The most common pulse to check for during CPR is the carotid pulse, which can be felt on the side of the neck. However, in emergency situations, any easily accessible pulse can be used to check for circulation, such as the brachial pulse in the upper arm, the femoral pulse in the groin, or the radial pulse on the wrist. The popliteal pulse behind the knee is not commonly used to check for circulation due to its location.
