Certified Nurses Operating Room (CNOR) Practice Exam

The maximum pressure range for initial insufflation flow during a procedure is often defined within 14-16 mm Hg. This range is critical for ensuring that the abdominal cavity is sufficiently distended to provide optimal visibility and access for surgical intervention without causing excessive pressure that can lead to complications.

Maintaining this pressure range helps prevent potential risks such as compromising the hemodynamic stability of the patient or causing damage to intra-abdominal organs. Appropriate insufflation pressure contributes to creating a workspace within the abdomen, allowing the surgeon to operate effectively while minimizing the risk of complications like pneumothorax or injury to surrounding tissues.

In surgical practice, understanding and adhering to these pressure limits is vital for patient safety and successful surgical outcomes.
