insufflating

Insufflating is the act of introducing a substance or gas into a body cavity or space by blowing or forcing it through a narrow opening. The term derives from Latin insufflare, to blow upon or into.

In medicine, insufflation refers to the deliberate introduction of gas into a body cavity to create space for visualization and instrumentation. In laparoscopy and other minimally invasive procedures, carbon dioxide is insufflated into the peritoneal cavity to lift the abdominal wall away from internal organs, creating a working space. Typical intra-abdominal pressures range from about 8 to 15 mmHg depending on the procedure and patient factors. Complications can include gas embolism, hypercarbia, acidosis, cardiovascular or respiratory effects, and inadvertent organ injury.

Nasal insufflation is a different context, in which powders, vapors, or aerosols are delivered through the nasal passages. This route is used for some medications and, historically, for illicit drugs such as cocaine. Advantages include rapid systemic absorption and avoidance of first-pass metabolism; disadvantages include nasal mucosal damage, septal perforation with chronic use, irritation, and variable dosing.

Other medical uses include insufflation of air or inert gases to distend cavities and improve visualization during procedures such as endoscopy, bronchoscopy, and gastroenterology, or to facilitate imaging and surgical access.

In sum, insufflating refers to the act of delivering a substance or gas by insufflation, with wide application in medical procedures and as a route of administration for certain substances. The context and the substance or gas used determine its purpose, benefits, and risks.
