First Aid For Hypertensive Emergency

Hypertensive emergency is a type of hypertensive crisis wherein blood level spikes to a very harmful level that it may potentially damage the organs of the body and cause other complications. There is a need to reduce blood pressure immediately to avoid imminent organ damage. Blood pressure readings is given in two numbers, written as 120/80 mmHg. The first number is called the systolic blood pressure whereas the second number is called the diastolic blood pressure. Normal blood pressure should read less than 120/80 mmHg most of the time, whereas hypertension is read as any number greater than 140/90 mmHg.
