blood pressure (BP)
The sounds we hear are "Korotkov" sounds
Measured in mm Hg
systolic blood pressure
The MAXIMUM pressure of blood pushing against an arterial wall
Occurs during ventricular CONTRACTION
FIRST Korotkov sound
diastolic blood pressure
The MINIMUM pressure of blood pushing against an arterial wall
Occurs during ventricular RELAXATION
LAST Korotkov sounds
Aneroid
A dial with a circular gauge and needle, portable
Factors Influencing Blood pressure
Cardiac output, blood volume, blood viscosity (thickness), HR, strength of contraction,
Peripheral vascular resistance, etc
Normal BP data
Less than or equal to 120/80
High normal BP
130-139/85-89
Hypotension BP
Systolic BP less than 90
Hypertension BP
140/90 or higher
Orthostatic (postural) hypotension
Decrease in both systolic and diastolic blood pressure upon standing
Due to failure of autonomic mechanisms to maintain BP
Locating the Brachial Artery (elbow area)
In the medial part of the antecubital fossa (sometimes it's located at superior to the
fossa)
What does a Nurse MUST NOT do during BP Assessment?
To take a BP on an "affected" arm
From CVA; surgery from breast, shoulder, arm; brace or cast
average adult oral temperature
37C (98.6F)
Normal range for temperature
36-38 degrees Celsius or 96.8-100.4 degrees Fahrenheit
Hypothalamus
The body's thermostat
Action of hypothalamus (body too warm)
Discomfort, Vasodilation and diaphoretic (sweaty)
