    MEMORANDUM OPINION1
    ----------
    Gerald Robert Stephenson, M.D. appeals from the trial court‟s interlocutory
    order refusing to dismiss the health care liability claims of appellees Natasha
    Miller, in her individual and other capacities, and Cynthia Miller, individually and
    in her other capacities. In two issues, appellant challenges the expert reports
    proffered by appellees as to standard of care and causation. We affirm.
    Procedural Background
    Appellees sued appellant, a surgeon who transplanted a kidney into Steve
    Miller, alleging that Miller died after appellant failed to recognize signs of
    postoperative bleeding, failed to timely order labs that would have purportedly
    diagnosed the bleeding at an earlier time, and failed to institute timely and
    appropriate therapies that would have prevented Miller‟s death from cardiac
    arrest. Appellant filed a motion to dismiss for failure to file an adequate expert
    report, which the trial court denied.
    Standard of Review
    1
    See Tex. R. App. P. 47.4.
    2
    A trial court=s decision on a motion to dismiss under section 74.351 is
    subject to an abuse of discretion standard. See, e.g., Am. Transitional Care Ctrs.
    of Tex., Inc. v. Palacios, 
    46 S.W.3d 873
    , 875 (Tex. 2001). To determine whether
    a trial court abused its discretion, we must decide whether the trial court acted
    without reference to any guiding rules or principles; in other words, we must
    decide whether the act was arbitrary or unreasonable. Downer v. Aquamarine
    Operators, Inc., 
    701 S.W.2d 238
    , 241–42 (Tex. 1985), cert. denied, 
    476 U.S. 1159
    (1986).    Merely because a trial court may decide a matter within its
    discretion in a different manner than an appellate court would in a similar
    circumstance does not demonstrate that an abuse of discretion has occurred. 
    Id. at 242.
    A trial court does not abuse its discretion if it commits a mere error in
    judgment. See E.I. du Pont de Nemours & Co. v. Robinson, 
    923 S.W.2d 549
    ,
    558 (Tex. 1995).
    Expert Report Requirements
    In a health care liability claim, a claimant must serve on each defendant an
    expert report that addresses standard of care, liability, and causation no later
    than the 120th day after the claim is filed. Tex. Civ. Prac. & Rem. Code Ann. '
    74.351(a), (j) (West 2011); Barber v. Mercer, 
    303 S.W.3d 786
    , 790 (Tex. App.––
    Fort Worth 2009, no pet.).     If an expert report has not been served on a
    defendant within the 120-day period, then on the motion of the affected
    defendant, the trial court must dismiss the claim with prejudice and award the
    defendant reasonable attorney=s fees and costs. Tex. Civ. Prac. & Rem. Code
    3
    Ann. ' 74.351(b); 
    Barber, 303 S.W.3d at 790
    . A report Ahas not been served@
    under the statute when it has been physically served but it is found deficient by
    the trial court.   Lewis v. Funderburk, 
    253 S.W.3d 204
    , 207–08 (Tex. 2008);
    
    Barber, 303 S.W.3d at 790
    B91. When no report has been served because the
    report that was served was found to be deficient, the trial court has discretion to
    grant one thirty-day extension to allow the claimant the opportunity to cure the
    deficiency. Tex. Civ. Prac. & Rem. Code Ann. ' 74.351(c); 
    Barber, 303 S.W.3d at 791
    .
    A report is deficient (therefore subjecting a claim to dismissal) when it
    Adoes not represent an objective good faith effort to comply with the definition of
    an expert report@ in the statute. Tex. Civ. Prac. & Rem. Code Ann. ' 74.351(l);
    
    Barber, 303 S.W.3d at 791
    . While the expert report Aneed not marshal all the
    plaintiff‟s proof,@ 
    Palacios, 46 S.W.3d at 878
    , it must provide a fair summary of
    the expert=s opinions as to the Aapplicable standards of care, the manner in which
    the care rendered by the physician or health care provider failed to meet the
    standards, and the causal relationship between that failure and the injury, harm,
    or damages claimed.@ Tex. Civ. Prac. & Rem. Code Ann. ' 74.351(r)(6); 
    Barber, 303 S.W.3d at 791
    .
    To qualify as a good faith effort, the report must Adiscuss the standard of
    care, breach, and causation with sufficient specificity to inform the defendant of
    the conduct the plaintiff has called into question and to provide a basis for the
    trial court to conclude that the claims have merit.@

    ;
    4
    
    Barber, 303 S.W.3d at 791
    . A report does not fulfill this requirement if it merely
    states the expert=s conclusions or if it omits any of the statutory requirements.
    
    Palacios, 46 S.W.3d at 879
    ; 
    Barber, 303 S.W.3d at 791
    . The information in the
    report Adoes not have to meet the same requirements as the evidence offered in
    a summary-judgment proceeding or at trial.@ 
    Palacios, 46 S.W.3d at 879
    ; 
    Barber, 303 S.W.3d at 791
    .       When reviewing the adequacy of a report, the only
    information relevant to the inquiry is the information contained within the four
    corners of the document alone.

    ; see Bowie Mem‟l Hosp. v. Wright, 
    79 S.W.3d 48
    , 52 (Tex. 2002). This
    requirement precludes a court from filling gaps in a report by drawing inferences
    or guessing as to what the expert likely meant or intended. 
    Barber, 303 S.W.3d at 791
    ; see Austin Heart, P.A. v. Webb,

    ).
    “[I]t is not enough that the expert report „provided insight‟ about the
    plaintiff‟s claims. Rather, to constitute a good-faith effort to establish the causal-
    relationship element, the expert report must fulfill Palacios‟s two-part test.”

    (Tex. App.––Texarkana 2006, no pet.)).          The report must provide enough
    5
    information within the document to both inform the defendant of the specific
    conduct at issue and to allow the trial court to conclude that the suit has merit.
    Bowie Mem’l Hosp., 79 S.W.3d. at 52.
    Analysis
    In two issues, appellant challenges the adequacy of the expert reports
    provided by appellees because (1) the standard of care and breach opinions
    lump all the doctors together collectively and (2) the causation opinions lump all
    the doctors together and fail to specify how the breaches caused Miller‟s death or
    specifically link those breaches to the cause of death.
    Standard of Care
    Dr. Ronald Ferguson, appellee‟s first expert, had over thirty years‟
    experience in the “practice of transplant surgery and the care of kidney transplant
    patients.”   He opined that appellant was aware of Miller‟s postoperative
    hematocrit drop to 21.72 and elevated potassium of 8.8; a note from appellant the
    morning after surgery notes the potassium of 8.8 “and the delayed graft function
    (DGF) of the transplanted kidney.” It also notes that Miller “would be scheduled
    to be hemodialyzed „today.‟” At 8:03 a.m. the morning after surgery, appellant
    made a requisition for 1 gram of calcium gluconate by IV for Miller.
    2
    In some parts of the report, Dr. Ferguson refers to the hematocrit drop as
    being to 21.7, and in others, he refers to it as being 22.7. For purposes of this
    opinion, the difference is not significant.
    6
    Dr. Ferguson noted that appellant was an independent contractor of Harris
    Methodist Hospital and that he was bound by their Renal Transplant Program
    2006 Protocol guidelines. According to Dr. Ferguson,
    The transplant surgeon is to be available post-operatively for
    the usual post-operative care, [and] for consultation with the Medical
    Director, including the occurrence of possible surgical problems.
    Concurrently, the nephrologists are responsible for the management
    of the transplant patients post-operatively. In the case of Steve
    Miller, nephrologists Linh Le, M.D., Rubina Khan, M.D., Shane
    Kennedy, M.D., and Charles Andrews, M.D., all part of Dialysis
    Associates, were to be responsible for the care of Steve Miller.
    In addition to the above operational guidelines set by the
    Protocol for the Kidney Transplant Program and Unit, the Protocol
    set had established guidelines for the Post Operative Management
    of the Transplant Recipient. The protocol is their standard of care
    for the post-operative care and management of a kidney transplant
    recipient.
    According to the Harris Methodist Hospital – Fort Worth Renal
    Transplant Program 2006 Protocol, applicable to the care of Steve
    Miller on April 2nd and 3rd, 2007, . . . Gerald R. Stephenson, M.D. . . .
    failed to implement this Protocol in the care of Steve Miller by failing
    to assess, monitor, and/or communicate Steve Miller‟s fractional
    urine output that was significantly lower than the 500 cc per four
    hours set as the standard quantitative guideline of the Protocol.
    Steve Miller, whose urine output post-operatively, was less
    than 20cc per hour since surgery, necessitated laboratory monitoring
    every four hours. Accordingly, the Protocol dictated that a complete
    blood count (CBC) and basic metabolic panel (BMP) were to be
    analyzed every four hours until routine labs the following morning.
    This Protocol, had it been implemented as dictated, would have
    provided a CBC, including a hemoglobin and hematocrit, and a
    BMP, which included a potassium level, at 9:30 p.m., 1:30 a.m., and
    5:30 a.m. This pattern of monitoring was critical in the care denied
    Steve Miller.
    ....
    7
    . . . Gerald Robert Stephenson, M.D., failed to implement
    Harris Methodist Hospital – Fort Worth – Renal Transplant Program
    2006 Protocol and obtain on Steve Miller a complete blood count
    and basic metabolic panel every four hours post-operatively until
    morning, necessitated by his oliguric status.             The protocol
    recognizes the minimal standard set forth in the community for
    kidney transplant patients. The standard approach recognized for
    laboratory monitoring in the first 24 hours post renal transplant would
    be to obtain testing for hemoglobin, hematocrit, and electrolytes (at
    least) every six hours for the first twenty four hours post
    transplant. . . .
    Had their own Protocol been implemented, or the community
    standard cited above, Steve Miller‟s post-operative bleeding and
    hyperkalemia[3] would have been detected at a much earlier time
    allowing much earlier treatment.
    ....
    ●      Dr. Stephenson is documented in the nursing records to
    be at Steve Miller‟s bedside at 7:30 a.m. on April 3,
    2007.
    ....
    ●      Christina Collier, R.N. reports that “Dr. Stephenson was
    actually in the unit making rounds, so I provided him
    with a copy of the morning labs.                This was
    approximately 7:30 a.m. on April 3, 2007. . . .[”]
    ●      Christina Collier, R.N., reports that Dr. Stephenson was
    at Steve Miller‟s bedside at 7:30 a.m., and documents it
    in the nurse‟s notes. Further documentation by Nurse
    Collier notes that “Dr. Kahn and Dr. Stephenson aware”
    of Steve Miller‟s laboratory values, including his
    potassium of 8.8 and his hematocrit of 22.7.
    ....
    3
    Hyperkalemia is “[a] greater than normal concentration of potassium ions
    in the circulating blood.” Stedman‟s Med. Dictionary 921 (28th ed. 2006).
    8
    In addition to having the critical, life threatening potassium
    level, indicating his severe hyperkalemia, Steve Miller was also
    hypovolemic,[4] having critically low hematocrit and hemoglobin
    values that were made known to Drs. Stephenson and Khan at 7:25
    a.m., on 4/3/07. At this time, Steve Miller‟s condition was extremely
    critical and life threatening. Mr. Miller‟s kidney had produced very
    little urine (oliguria) and the hematocrit and hemoglobin values
    indicated an internal hemorrhage. As indicated before, the accepted
    standard for medical care for such a patient in critical condition
    would require urgent therapy with intravenous Calcium Gluconate or
    an insulin and glucose combination. . . .
    ....
    Furthermore, [although Dr. Khan ordered 1 gram of calcium
    gluconate “now”] neither Dr. Khan nor Dr. Stephenson took
    responsibility to assure that the Calcium Gluconate was immediately
    processed and administered. In fact, Dr. Stephenson testifies that
    he left the entire clinical emergency management of Steve Miller up
    to Dr. Khan, absent the ordering [of] an advancement of Steve
    Miller‟s diet to „clear liquids‟.
    Drs. Khan and Stephenson, Nurses Laureano, Collier, and
    Dickerson, Harris Methodist Fort Worth Hospital and its health care
    providers, each had a duty, as respective medical doctors,
    registered nurses and health care providers of Harris Methodist
    Hospital – Fort Worth, to Steve Miller, in an emergency situation, to
    see that the „Now‟ order was immediately communicated to the
    pharmacy, [and] processed and administered to Steve Miller within
    one hour. Steve Miller was administered the Calcium Gluconate
    over two hours later. This is below the standard of care for medical
    doctors, specifically Rubina Khan, M.D. and Gerald Stephenson,
    M.D. . . .
    ....
    1.     The standard of care for a post-operative kidney
    transplant patient is to have a blood assessment, at the
    very minimum, every six hours, post-operatively, which
    4
    Hypovolemic means having “a decreased amount of blood in the body.”
    
    Id. at 939.
    9
    would include a basic metabolic panel. The standard of
    care would require that both the surgeon, in this case,
    Dr. Gerald Stephenson, M.D., and the nephrologist
    group (Dialysis Associates), and the individual
    nephrologist, in this case, Linh Le, M.D., Shane
    Kennedy, M.D. and Rubina Khan, M.D., would be
    responsible for seeing that such order was entered. . . .
    ....
    3.     The medical records do not indicate that either Drs.
    Stephenson or Khan properly diagnosed the fact that
    Steve Miller was hypovolemic as a result of an internal
    hemorrhage, which was causing his low hematocrit and
    hemoglobin levels (as well as the critical potassium
    value of 8.8). The calcium gluconate, together with the
    insulin glucose combination should have been given
    intravenously and immediately. The accepted standard
    of care would require the proper diagnosis be made of
    Steve Miller‟s critical condition that he was bleeding
    internally, and thus, hyperkalemic, and the standard of
    care would require that he be administered the above
    therapy intravenously and that both Drs. Khan and
    Stephenson should have made certain that this order
    was carried out and that therapy was given immediately.
    It was a violation of the standard of care for them not to
    do so. . . .
    4.     It was a violation of the standard of care to not order the
    intravenous timely administration of Calcium Gluconate
    or the insulin glucose combination as well as dialysis,
    without ultrafiltration. . . .
    . . . Both Drs. Stephenson and Khan failed to treat the
    primary cause of Steve Miller’s hyperkalemia, the post-
    operative bleeding. The accepted standard of care for a
    post-operative kidney patient, such as Steve Miller,
    would have been not to decrease his fluid volume,
    created quite possibly by surgical post-operative
    bleeding, and to treat medically his hyperkalemia.
    Rubina Khan, M.D. and Gerald Robert Stephenson,
    M.D. failed to perform any of these that were required
    by the accepted standards of care, for a patient of Mr.
    10
    Miller‟s condition. Furthermore, it is a violation of the
    standard of care by both Rubina Khan, M.D. and Gerald
    Robert Stephenson, M.D., both of whom had the
    responsibility for Steve Miller upon examining him at
    7:25 a.m., on 4/03/07, to order and/or permit him to
    receive ultrafiltration . . . . The standard of care for the
    nephrologist on duty in the early morning hours of
    4/03/07, . . . as well as . . . Dr. Stephenson, the kidney
    transplant surgeon, was to diagnose Steve Miller as
    suffering from post-operative bleeding which required
    immediate treatment . . . . Rubina Khan, M.D. and
    Gerald Robert Stephenson, M.D. failed to take any of
    the appropriate actions necessary to treat the extremely
    critical conditions caused by Steve Miller‟s post-
    operative bleeding. [Emphasis added.]
    Dr. Gallon, appellees‟ second expert, had over ten years‟ experience in the
    practice of transplant surgery and the care of transplant patients. He states in his
    report that the nephrologists were responsible for postoperative management of
    transplant patients and that “[t]he transplant surgeon, Gerald Robert Stephenson,
    M.D., was concurrently responsible for Steve Miller‟s post-operative monitoring,
    care and intervention as it related to the surgical procedure and potential
    complications and/or issues related to the kidney allograft.”
    “Concurrent” is defined as “[o]perating at the same time[,]… covering the
    same matters.”     Black‟s Law Dictionary 331 (9th ed. 2009).         A reasonable
    construction of Dr. Ferguson‟s and Dr. Gallon‟s use of the word “concurrently” in
    their reports is that Dr. Stephenson was to be available for the usual post-
    operative care of Miller and that he was to be responsible for the post-operative
    management of Miller along with the nephrologists. Thus, any references in the
    report to a joint standard of care involving the post-operative management of
    11
    Miller would be appropriate. See, e.g., Barber v. Dean, 
    303 S.W.3d 819
    , 831
    (Tex. App.––Fort Worth 2009, no pet.). The excerpts above show that both Dr.
    Ferguson and Dr. Gallon concluded and opined that under Harris‟s Protocol, as
    well as prevailing standards of care for post-operative care and management of a
    patient, the transplant surgeon was responsible for both post-operative care and
    management of a patient like Miller. Both reports clearly state that the articulated
    standards of care are applicable to both Dr. Stephenson and the nephrologists;
    Dr. Ferguson‟s report also states how Dr. Stephenson as well as the
    nephrologists breached that standard.         Thus, the expert reports proffered by
    appellees fulfill their statutory purpose: to provide enough information within the
    document to both inform the defendant of the specific conduct at issue and to
    allow the trial court to conclude that the suit has merit. See Bowie Mem’l Hosp.,
    79 S.W.3d. at 52.
    We overrule appellant‟s first issue.
    Causation
    Appellant further contends that Dr. Ferguson‟s and Dr. Gallon‟s reports are
    deficient because they are conclusory and “also lump all physicians and
    defendants together for causation.”
    Appellant contends that appellees‟ experts failed to explain how he is
    linked to Miller‟s cardiac arrest, which occurred during ultrafiltration by Dr. Khan,
    the nephrologist.    According to appellant, the court must make improper
    inferences to “glean precisely how it is that the care of Appellant Dr. Stephenson
    12
    himself . . . caused the death of the patient.” He contends Dr. Gallon‟s report
    fails for the same reason because it is “not surprisingly identical to [that] of Dr.
    Ferguson.”
    Dr. Ferguson opined as follows:
    Had their own Protocol been implemented, or the community
    standard cited above, Steve Miller‟s post-operative bleeding and
    hyperkalemia would have been detected at a much earlier time
    allowing much earlier treatment.
    ....
    3.     The critical potassium value indicating the hyperkalemia
    condition that could immediately cause a patient to develop life-
    threatening arrhythmia required aggressive treatment as soon as
    that condition was diagnosed by the blood sample that was drawn at
    3:40 a.m. . . . [A]t 7:25 a.m., on 4/3/07 . . . Steve Miller‟s condition
    was extremely critical and life-threatening. Mr. Miller‟s kidney had
    produced very little urine (oliguria) and the hematocrit and
    hemoglobin values indicated an internal hemorrhage. . . .
    4.    . . . The ultrafiltration removed fluid volume from Steve Miller
    who was already presenting with a compromised hypovolemic
    condition, and was the finishing catalyst in Steve Miller‟s
    hemodynamic[5] collapse and a contributing cause to his death at
    11:27 a.m. on 4/3/07.
    . . . . Due to the cumulative effect of the negligent care, aggressive
    medical management of the hyperkalemia, followed by an operation
    to control bleeding or intraoperative dialysis, with life-support
    measures, accompanied by surgical repair of the postoperative
    bleeding, were at the time, (7:25 a.m.), the only heroic and plausible
    interventions to save the life of this 24 year-old young man.
    ....
    5
    Hemodynamic means “[r]elating to the physical aspects of the blood
    circulation.” 
    Id. at 868.
    13
    . . . [Miller] died of a cardiac arrest while in dialysis in a state of
    uncontrovertible ventricular tachycardia. . . . He experienced
    postoperative bleeding that caused dangerous hyperkalemia. A
    decision to use dialysis to treat the life threatening hyperkalemia,
    rather than, or in addition to, aggressive medical management, was
    made. While on dialysis, ultrafiltration led to hypotension as it
    frequently does in the early post-transplant dialysis setting and
    definitely does in a compromised hypovolemic post-surgical state.
    This was not recognized, but in fact, more fluid volume was removed
    by ultrafiltration that exacerbated rather than improved the
    hypotension and hypovolemic, thus setting up an environment of
    uncorrected hyperkalemia (repeat potassium in dialysis of 7.9),
    acidosis (arterial pH of 7.166), hypotension, hypovolemic, hypoxia,
    and ventricular tachycardia. Given this setting and environment, it is
    not surprising that the ventricular tachycardia could not be
    successfully reversed and became the ultimate cause of death.
    ....
    Each of the standards of care as I have indicated above was a
    proximate cause of the death of Steve Miller. . . . Earlier, had he
    received the proper treatment, Steve Miller, in all reasonable medical
    probability, would have resulted in his being able to survive the post-
    operative bleeding. . . . The failure to properly treat Steve Miller‟s
    condition by Rubina Khan, M.D., Shane Kennedy, M.D., Gerald
    Robert Stephenson, M.D. and Patricia Fenderson, M.D. [the Director
    of Harris Methodist Hospital – Fort Worth], combined with the failure
    of the nurses and health care providers . . . all of which . . . caused
    Steve Miller to ultimately go into cardiac arrest from which he could
    not be resuscitated, thus, causing his death. Each of the above
    violations of the standard of care was a proximate cause of Steve
    Miller‟s death.
    Earlier in his report, Dr. Ferguson faults Dr. Stephenson for breaching the
    following standards of care: failing to ensure the Protocol was implemented as to
    timely CBC and BMP laboratory tests, failing to ensure that Dr. Khan‟s “now”
    order for calcium gluconate was immediately processed, failing to diagnose and
    treat the primary cause of Miller‟s hyperkalemia, which was the postoperative
    14
    bleeding, and allowing Dr. Khan to order ultrafiltration when it was not indicated.
    In his report, he states that had the Protocol been implemented, Miller‟s
    hyperkalemic condition would have been evident earlier and would not have
    eventually progressed to ventricular tachycardia. According to Dr. Ferguson, Dr.
    Stephenson‟s failure to diagnose the underlying cause of Miller‟s hyperkalemia
    and his allowing the ultrafiltration exacerbated that continuing hyperkalemic
    condition, which eventually led to irreversible ventricular tachycardia.        Dr.
    Ferguson‟s report describes a chain of omissions that each had the effect of
    further exacerbating Miller‟s condition until it became irreversible.   See, e.g.,
    Menefee v. Ohman, 
    323 S.W.3d 509
    , 519–20 (Tex. App.––Fort Worth 2010, no
    pet.); Presbyterian Cmty. Hosp. of Denton v. Smith, 
    314 S.W.3d 508
    , 518–19
    (Tex. App.––Fort Worth 2010, no pet.); see also Del Lago Partners, Inc. v. Smith,
    
    307 S.W.3d 762
    , 774 (Tex. 2010) (holding that there may be more than one
    proximate cause of an event).
    Accordingly, we conclude and hold that Dr. Ferguson‟s opinions on
    causation are not conclusory, nor do they fail for lack of specificity as to Dr.
    Stephenson, with respect to each of the alleged standard of care violations
    except for the failure to ensure the timely administration of calcium gluconate or
    insulin. Dr. Ferguson does not explain how that failure was a proximate cause of
    Miller‟s death. However, Dr. Gallon states in his report that intravenous calcium
    gluconate would “stabilize the myocardium” and an insulin/glucose combination
    would “treat the hyperkalemia.” Thus, reading both reports together, the alleged
    15
    failure to ensure the timely administration of the proper medication was another
    omission in the chain that led to the exacerbation of Miller‟s hyperkalemia and
    ultimate cardiac arrest. See Tex. Civ. Prac. & Rem. Code Ann. § 74.351(i);
    Davisson v. Nicholson, 
    310 S.W.3d 543
    , 558 (Tex. App.––Fort Worth 2010, no
    pet.) (op. on reh‟g); Packard v. Guerra, 
    252 S.W.3d 511
    , 526–27 (Tex. App.––
    Houston [14th Dist.] 2008, pet. denied) (holding that we must review multiple
    reports “in the aggregate” to determine if they are adequate as to liability and
    causation).
    We conclude and hold that the trial court did not abuse its discretion by
    determining that the expert reports proffered by appellees constituted a good
    faith effort to comply with the statute. We overrule appellant‟s second issue.
    Conclusion
    Having overruled both of appellant‟s issues, we affirm the trial court‟s
    order.
