“appellants”), challenge the trial court’s order denying their motion to dismiss the health care liability claims2 brought against them by appellee, Marquita Jones (“Marquita”), as Power of Attorney for Shronda Jones (“Shronda”), in her suit for negligence. In their sole issue, appellants contend that the trial court erred in denying their motion to dismiss Marquita’s claims against them.3 We affirm.

Background

In her petition, Marquita alleges that on June 2, 2022, Shronda went to Memorial Hermann Texas International Endoscopy Center, doing business as Texas International Endoscopy Center (“Texas International Endoscopy Center”), for a colonoscopy procedure that was performed by Andrea Duchini, M.D. Shaffer, a certified registered nurse anesthetist, administered Shronda anesthesia for the colonoscopy procedure and was supervised by Les Yarmush, M.D. After the induction of anesthesia and approximately four minutes after the start of the procedure, at about 9:30 a.m., Shronda developed bradycardia and hypotension. According to Marquita, Shaffer did not tell Dr. Yarmush of Shronda’s “change in

status” for fifteen minutes, and during that time, Dr. Duchini continued with the colonoscopy procedure.

At 9:45 a.m., Dr. Yarmush arrived “to administer advanced cardiac life support” to Shronda. At 10:00 a.m., emergency medical services arrived and transported Shronda “to a subsequent facility where she was placed” in the intensive care unit (“ICU”). Shronda was diagnosed with “an anoxic brain injury as a result of prolonged oxygen loss.”4 Marquita brings a health care liability claim against Shaffer, alleging that he was negligent in failing to adequately and timely treat Shronda’s bradycardia and hypotension and was negligent in failing to timely report the complications during the colonoscopy procedure to his supervisor, Dr. Yarmush. In doing so, Shaffer breached the standard of care which was the proximate cause of the injuries sustained by Shronda. Marquita also brings a health care liability claim against Dr. Yarmush, asserting that he was negligent in failing to properly supervise Shaffer during the colonoscopy procedure, in failing to promptly diagnose and treat Shronda’s bradycardia and hypotension, and in performing advanced cardiac life support.

doing so, Dr. Yarmush breached the standard of care which was the proximate cause of the injuries sustained by Shronda.5 Additionally, Marquita brings vicarious liability health care liability claims against Epix Medical Services, alleging that it is vicariously liable for the negligence of Shaffer and Dr. Yarmush, who were acting in the course and scope of their employment at all relevant times.6 Marquita requested damages.

To support her health care liability claims, Marquita served appellants with an expert report authored by Jon Reynolds, M.D.7 In his expert report, Dr. Reynolds states that he is a board certified anesthesiologist and licensed to practice medicine in North Carolina. He is an associate professor of anesthesiology at Atrium Wake Forest Baptist Health and the medical director for procedural sedation at Wake Forest Baptist Medical Center. According to Dr. Reynolds, he has “substantial experience personally providing and medically directing anesthesia for colonoscopies.”

Further, Dr. Reynolds states that he is familiar with the applicable standard of care for anesthesia related to Shronda’s case based on his medical education and his

6 In her suit, Marquita also brought health care liability claims against Dr. Duchini and another entity, Gastroenterology and Transplant Hepatology International, P.A., but they are not parties to this appeal. Marquita nonsuited her claims against Memorial Hermann Endoscopy Center, who is also not a party to this appeal.

residency training in anesthesiology. Dr. Reynolds has consistently practiced in an endoscopy and colonoscopy setting, continued his medical education, and has maintained his board certification which allows him to have “a clear knowledge and familiarity of the [s]tandard[] of [c]are” relevant to the instant case. He is “familiar with the nation-wide provision of anesthesia for colonoscopies, now routinely provided by anesthesia staff using the more rapid and efficient drug propofol rather than sedatives administered by a gastrointestinal physician and a [r]egistered [n]urse.” His “education, background, and experience, and working with nursing staff and other physicians, including gastroenterologists, in an endoscopy setting,” has given him “knowledge of the accepted standard[] of care for physicians and nursing staff participating in [an] endoscopy and colonoscopy setting.”

As to Shronda, Dr. Reynolds’s expert report states that on June 2, 2022, Shronda went to the Texas International Endoscopy Center for a screening colonoscopy procedure. Dr. Duchini performed the procedure. Shaffer gave Shronda anesthesia for the procedure and was “medically directed” by Dr. Yarmush during the delivery of the anesthetic. After the induction of anesthesia and four minutes after the start of the colonoscopy procedure, at about 9:30 a.m., Shronda developed bradycardia. However, Shronda was not provided with “a higher concentration of oxygen via a bag-valve-mask . . . apparatus” until 9:46 a.m., sixteen minutes after she developed bradycardia. Shronda became hypotensive at

approximately 9:31 a.m. Sixteen minutes elapsed where Shronda’s breathing was not charted as either spontaneous or assisted in the anesthesia record. There is no evidence that Shaffer communicated with Dr. Yarmush that Shronda’s vital signs were unstable until 9:45 a.m. There is no evidence that the colonoscopy procedure was paused or terminated to see if that would resolve Shronda’s bradycardia or hypotension. Dr. Duchini continued performing the colonoscopy procedure until 9:45 a.m.

Dr. Reynolds’s report further states that at 9:45 a.m., fifteen minutes after Shronda’s vital signs had dropped, Dr. Yarmush was “called emergently to and arrived in the procedure room” where he ordered advanced cardiac life support, consisting of atropine, ephedrine, oxygen by bag-valve-mask, epinephrine, cardiopulmonary resuscitation (“CPR”), and ultimately intubation of the trachea. Shronda was intubated nine minutes after Dr. Yarmush arrived. Subsequently, Shronda was transported by emergency medical services to the hospital and admitted to the ICU. At the hospital, she remained intubated and was diagnosed with an anoxic brain injury resulting in severe injury and disability.

As to Shaffer, Dr. Reynolds’s expert report states that the standard of care for Shaffer, a certified registered nurse anesthetist, during the colonoscopy procedure, was to monitor Shronda’s blood pressure while she was under anesthesia and to adequately and timely treat a change in her blood pressure.
