What is the norm blood pressure & units ?
Average blood pressure is (120 / 80) mmHg
How do you measure blood pressure manually?
1. Manual blood pressure is measured with a quality stethoscope, appropriately sized blood pressure cuff & sphygmomanometer.
2 Perpare the partient by resting them for 5 minutes.
3. Place the BP cuff along the patients brachial artery, so the artery marker points to the brachial artery.
4. Postition the stethoscope, at the antecubical fossa (crease of the arm) to locate the strongest pulse.
5. Inflate the BP cuff & listen until the blood flow has stopped (no sound through the stethoscopre)
6. Slowly deflare the BP cuff & listen for the systolic reading (first occurence of rhythmic sound
7. Listen for the Diastolic reading of the rhythmic sound stopping.
8. Double check for accuracry.
Define systolic & diastolic blood pressure?
- A normal systolic blood pressure reading is 90 - 120mm Hg.
- Measure of the amount of pressure that blood exerts on the arteries & vessels while the heart beats .
- Left ventricle contracts
- Represents the maximum pressure exerted on the arteries.
- A normal diastolic blood pressure reading is 60 - 80mm Hg.
- Measure of the pressure exerted on the walls of artieries in between heart beats (when the heart is relaxed)
- Ventricles of the heart fill with blood
- Represents the minimum pressure in the arteries.
Affects of exercise (walking) on blood pressure?
