MODEL RELEASED. Blood pressure. Nurse takes the blood pressure of an elderly woman in an old age home. The nurse is using a sphygmomanometer. The cuff on the patient's upper arm is inflated until it is tight enough to stop the flow of blood in the main artery. The cuff is slowly deflated and,using the stethoscope to listen to the pulse,both systolic (pumping heart) and diastolic pressure (relaxed heart) are taken. Blood pressure is expressed as the difference between these two measurements,in millimetres of mercury (mm Hg). Blood pressure is an important measure of bodily health | |
