Which component of the inflation device indicates the pressure during inflation?

The component of the inflation device that indicates the pressure during inflation is the pressure gauge. This instrument is crucial in interventional procedures as it provides real-time feedback on the amount of pressure being applied to the balloon or other devices during inflation. Monitoring pressure is vital to ensure that the inflation is performed safely and effectively, preventing complications such as over-inflation, which could damage blood vessels or surrounding tissues. The pressure gauge allows healthcare professionals to adjust the inflation according to the specific needs of the procedure and to ensure that the desired outcome is achieved without exceeding safe limits.

The barrel, plunger, and tubing serve different functions in the inflation device; the barrel holds the inflation fluid, the plunger is used to apply force to expel the fluid from the barrel, and the tubing connects the device to the balloon or area that requires inflation but does not provide pressure readings.
