What is hypotension and hypertension (blood pressure ) range ?
Hypotension (HI-po-TEN-shun) is abnormally low blood pressure. Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood. Blood pressure is measured as systolic (sis-TOL-ik) and diastolic (di-a-STOL-ik) pressures. “Systolic” refers to blood pressure when the heart beats while pumping blood. “Diastolic” refers to blood pressure when the heart is at rest between beats. You most often will see blood pressure numbers written with the systolic number above or before the diastolic number, such as 120/80 mmHg. (The mmHg is millimeters of mercurythe units used to measure blood pressure.) Normal blood pressure in adults is lower than 120/80 mmHg. Hypotension is blood pressure that’s lower than 90/60 mmHg. Hypertension (HTN) or high blood pressure is a chronic medical condition in which the systemic arterial blood pressure is elevated. It is the opposite of hypotension. It is classified as either primary (essential) or secondary.
