Final answer:
Abdominal insufflation, which involves introducing gas into the abdominal cavity during surgery, has physiological effects on respiratory, cardiovascular, and gastrointestinal functions. It restricts lung expansion, decreases blood flow to the lower extremities, and can cause gastrointestinal issues.
Step-by-step explanation:
The physiologic response to abdominal insufflation is the increase in intra-abdominal pressure, which affects various body systems. Abdominal insufflation is the process of introducing gas into the abdominal cavity during surgical procedures, such as laparoscopy. This increase in pressure can impact respiratory function, cardiovascular function, and gastrointestinal function.
Respiratory function: Abdominal insufflation causes the diaphragm to be pushed upwards, restricting lung expansion and decreasing respiratory function. This can lead to decreased oxygen levels and increased carbon dioxide levels in the blood.
Cardiovascular function: The increase in intra-abdominal pressure can compress the blood vessels in the abdomen, impeding blood flow to and from the lower extremities. This can result in decreased venous return and cardiac output.
Gastrointestinal function: Abdominal insufflation can cause distension and displacement of the abdominal organs, potentially leading to impaired intestinal motility, delayed gastric emptying, and altered bowel function.
