POSED BY MODELS. Blood pressure check. Elderly man having his blood pressure measured as part of a check-up by a general practice doctor. The black cuff on his arm is inflated until it stops blood flow, and then released. The reading on the dial at lower centre gives first his systolic pressure and then his diastolic pressure as normal blood flow resumes. Blood pressure is an important measure of cardiac fitness and all-round health.
