polspulsdruk

Polspulsdruk, also known as blood pressure, is a measure of the force exerted by blood against the walls of the arteries as the heart pumps. It is typically expressed in millimeters of mercury (mmHg) and is given as two numbers: systolic pressure (the pressure when the heart beats) and diastolic pressure (the pressure when the heart rests between beats). Normal blood pressure is generally considered to be less than 120/80 mmHg.

Blood pressure can be measured using a sphygmomanometer, an instrument that inflates a cuff around the upper arm to restrict blood flow. The cuff is then slowly deflated, and a stethoscope is used to listen for the sound of blood flowing through the artery. The systolic pressure is the point at which the sound first becomes audible, and the diastolic pressure is the point at which the sound disappears.

High blood pressure, or hypertension, is a common condition that can lead to serious health problems such as heart disease, stroke, and kidney failure. It is often referred to as the "silent killer" because it may not cause any symptoms and can go undetected for years. Low blood pressure, or hypotension, can also be a problem, particularly in older adults, and can cause symptoms such as dizziness, fainting, and confusion.

Blood pressure can be influenced by a variety of factors, including age, sex, weight, diet, and lifestyle. Regular monitoring of blood pressure is recommended for people with risk factors for hypertension, such as obesity, diabetes, and a family history of high blood pressure. Treatment for hypertension typically involves lifestyle modifications such as a healthy diet, regular exercise, and weight loss, as well as medication if necessary.
