What is a recommended action if a patient feels choking or pressure during ERCP?

In the context of an Endoscopic Retrograde Cholangiopancreatography (ERCP) procedure, if a patient experiences sensations of choking or pressure, it is crucial for them to remain calm and allow the procedure to continue. This recommendation is based on the understanding that some degree of discomfort is common during ERCP, as the procedure involves the manipulation of tools within the esophagus and duodenum, which can trigger such sensations.

While it is essential for the patient to communicate any feelings of distress to the medical team, maintaining calmness allows the healthcare providers to assess the situation and proceed safely. Stopping the procedure abruptly could lead to complications or incomplete diagnostic evaluations. The medical team is trained to manage discomfort and can adjust their approach or provide assistance while ensuring the procedure's integrity and the patient's safety.

The other options do not effectively support the procedural flow and the safety of the patient. Asking to stop the procedure might not be the best immediate action, and leaving the examination room could lead to further complications. Raising a hand to signal the nurse can be helpful, but it might not be as effective as the patient focusing on staying calm to help the team manage the situation while they continue the necessary interventions.
