The blood pressure assessment measures the force exerted by circulating blood on the walls of blood vessels, the pressure in the larger arteries and blood vessels that take blood away from the heart to the body.
The top number is called systolic and is the contraction of heart chambers, driving blood out of the chambers. The bottom number is called diastolic pressure and is the blood pressure when the heart is relaxed.
As blood pressure is continually changing depending on activity, temperature, diet, emotional state, posture, physical state, and medication use, ensure your client is relaxed and well rested. If the client is nervous, do some deep breathing before the test and ask them if they are relaxed before continuing.
If the client is on Blood Pressure medication, then enter 140/90.
