How to Assess Blood Pressure
![Page 2: How to Assess Blood Pressure. What is blood pressure? Blood pressure is the measurement of the pressure that the blood exerts on the walls of the arteries.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d885503460f94a6dce0/html5/thumbnails/2.jpg)
What is blood pressure?
• Blood pressure is the measurement of the pressure that the blood exerts on the walls of the arteries during the various stages of heart activity.

2 Types of Blood Pressure Measurement
• Systolic: pressure in walls of arteries when the left ventricle is contracting
• Diastolic: pressure when left ventricle is at rest (or between contractions)

How do we record Blood Pressure?
• BP• Systolic/Diastolic
![Page 7: How to Assess Blood Pressure. What is blood pressure? Blood pressure is the measurement of the pressure that the blood exerts on the walls of the arteries.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649d885503460f94a6dce0/html5/thumbnails/7.jpg)
BP Norms:
Category Systolic Diastolic
Normal Blood Pressure
<120 <80
Normal Range 100-120 60-80
Hypertension (high blood pressure)
>140 >90
Hypotension(low blood pressure)
<90 <60

Normal or Abnormal?
• 120/70• 210/100• 100/40• 110/68• 102/60• 140/70• 120/94
Normal range:
Systolic: 100-120 Diastolic: 60-80

Application:
• Read the definitions/info on Hypertension and Hypotension on page 447.
• List 5 causes of hypertension• List 5 causes of hypotension• What is orthostatic hypotension? What are
the S&S?• Why is hypertension often called the “silent
killer”?

5 Causes of Hypertension
• Stress• Anxiety• Obesity• High salt intake• Aging• Kidney disease• Thyroid deficiency• arteriosclerosis

5 Causes of Hypotension
• Heart failure• Dehydration• Severe burns• Depression• Hemorrhage• Shock• Orthostatic hypotension: sudden drop in BP
when pt moves from lying to sitting/standing

Let’s Practice!
Must maintain very quiet environment to make proper assessment.NO horseplay!Do not overinflate cuff.Must remove jackets/hoodies.Must roll up sleeve to expose arm.

BP Assessment
• Expose arm• Identify antecubital space• Identify brachial artery• Place cuff approx. 1 inch above brachial artery• Inflate cuff to approx. 160mm Hg• Open bulb valve SLOWLY!• 1st sound: systolic• Last sound: diastolic
