What does insufflation mean in a medical context?

Insufflation in a medical context specifically refers to the process of introducing gas or air into a body cavity. This technique is often used in various diagnostic and therapeutic procedures, such as when performing laparoscopy, where carbon dioxide is insufflated into the abdominal cavity to create space and improve visibility for the surgeon. Insufflation can also be applied in procedures like the administration of certain medications or anesthetics, where gas is introduced directly into the respiratory system or other cavities for effective treatment.

The other options describe different processes that do not align with the definition of insufflation. For instance, removing fluid from the lungs relates directly to therapeutic procedures like thoracentesis, while compressing gas into a cylinder refers to gas storage techniques. Delivering oxygen through a mask describes a method of respiratory support rather than a process of gas introduction into a cavity.
