Hypertension | Hypotension | Cardiac output
HYPERTENSION
- The increase in blood pressure than the normal range of blood pressure is called hypertension.it is also called high blood pressure. in this, both systolic and diastolic values are higher than the normal values.
- Hypertension is produced due to tension, worries, less elasticity of blood vessels.it is dangerous because such a person may get heart failure of the attack.
HYPOTENSION
- The decrease in the blood pressure than the normal range of blood pressure is called hypotension.it is also called as low blood pressure. in this, both systolic and diastolic values of blood pressure are less than the normal values.
- Hypotension is produced due to less volume of blood in the body. it is also dangerous because such a person may get heart failure or attack.
CARDIAC OUTPUT
- The total volume of blood pumped by the heart in one minute is called the cardiac output.
- Heart Rate:- The total number of heartbeats per minute is known as heart rate.in normal healthy man, the heart rate is 72 beats per minute.
- Stroke Volume:- During each ventricular contraction or systole about 70ml. of blood is pumped out, this known as stroke volume.
Thus, The cardiac output can be calculated by formula as, cardiac output=heart rate x stroke volume.=72×70=5040ml.
Thus, The cardiac output of the normal man is about 5litres pr minute.
