Electronics and Instrumentation Engineering Quiz

The indirect method involves using a sphygmomanometer to compress the artery and estimate pressure based on the sounds heard through a stethoscope.

Direct measurement involves inserting a catheter into the bloodstream while indirect measurement uses a sphygmomanometer.

The two methods are utilizing a pressure transducer connected to the catheter and using a manometer.
