25
Consistently high= arteriosclerosis
Wide/High Pulse Pressure
A type of vascular disease where the blood vessels carrying oxygen away from the heart (arteries) become damaged from factors such as high cholesterol, high blood pressure, diabetes and certain genetic influences.
Arteriosclerosis
High PP= (>__ mmHg)
55
Maximize pressure of blood exerted on the arterial wall at the peak of the contraction of the left ventricle.
Systolic Blood Pressure (SBP)
Minimum pressure of blood exerted when the left ventricle is at rest but receives blood from atrium.
Diastolic Blood Pressure (DBP)
Recommendations: Healthy lifestyle choices and yearly checks.
Normal Blood Pressure
<120 mmHg
<80 mmHg
Recommendations: healthy lifestyle changes, reassess on 3-6 months
Elevated Blood Pressure
120-129
<80
Recommendations: 10-year heart disease and stroke risk assessment. If less than 10% risk, lifestyle changes, reassessed in 3-6 months. If higher, lifestyle changes and medication with mostly follow-ups with BP controlled.
High Blood Pressure/ Stage 1
130-139
80-89
Recommendations: lifestyle changes and 2 different classes of medicine, with monthly follow-ups until BP is controlled.
High Blood Pressure/ Stage 2
>140
>90
90/60 mmHg
Borderline low blood pressure
60/40 mmHg
Too low blood pressure
50/33 mmHg
Dangerously low blood pressure
Most serious and dangerous to organs. It can damage kidneys.
Low blood pressure
When the systolic is high but the diastolic is normal.
Isolated Systolic Hypertension
Equipments for BP
Sphygmomanometer
Stethoscope
4 locations in taking the BP
Radial Artery

R: If arm dangles, client may perform isometric exercises that can increase _______ pressure __%
Diastolic
10
Position cuff ____cm (1 inch) above site of brachial pulsation (________ space).
2.5
Antecubital
Loose fitting of cuff causes_______readings.
False high
Eye level placement ensures _____ reading of mercury level.
Accurate
When no stethoscope palpate the radial artery then when the pulse stops add ______
30 mmHg
Proper stethoscope placement ensures optimal _______ ______.
Sound receptions
Stethoscope improperly positioned causes _____ sounds that often results in false ___ systolic and false ____ diastolic pressure.
Muffled
Low

_______ korotkoff sound involves distinct muffling of sounds and is recommended by _______ Heart ________ as indication of diastolic pressure in ________.
Fourth
American
Association
Children
_____ can be measured in ° fahrenheit and _______
Temperature

How is body heat produced?
- Exercise- walking, doing activities
- Eating- metabolism of food (kinetic energy in cells)
How is body heat lost?
Skin- sweat glands by perspiration
Lungs through breathing during ventilation
