Abstract
According to one embodiment, a method includes positioning a trocar having a primary pressure sensor in or on the trocar into a patient cavity. The method also includes supplying an insufflation fluid to the patient cavity and measuring a pressure in the patient cavity by the primary pressure sensor. The method further includes controlling the supply of insufflation fluid by an insufflator to the patient cavity based at least on the measured pressure and determining by a processor associated with the insufflator that the measured pressure may be inaccurate and in response, controlling, by the insufflator, the supply of insufflation fluid to the patient cavity based at least on a pressure measured by a backup pressure sensor rather than based on the measured pressure.
