Term
Define "Blood Pressure"
Definition
(BP) is a mesaure of the lateral force per unit area of the vascular wall and is conventionally expressed in millimeters of mercury (mmHg)
Term
Define "Systolic Pressure"
Definition
Systolic pressure is the highest pressure within the cardiac cycle, occurring just after contraction of the left ventricle. Normally about 120 mmHg. Considered abnormal if persistently above 140 mmHg
Term
Define "Diastolic Pressure"
Definition
Diastolic pressure is the lowest pressure within the cardiac cycle, occurring during the relaxation phase between heart beats, normally about 80 mmHg. Diastolic pressure persistently above 90 mmHg is considered abnormal
Term
What is "Pulse Pressure"?
Definition
The difference between systolic and diastolic pressures
Term
What is "Mean Arterial Pressure"?
Definition

(MAP) is the average pressure throughout each cycle of the heartbeat tending to push the blood through systemic circulatory system.

 

1/3 Pulse Pressure+Diastolic Pressure.

Term
What Korotkov sounds are you listening for to determine the patient's blood pressure?
Definition
Phase I for systole and phase V for diastole expressed 120/80 mmHg. If phase IV is observed then the BP can be expressed 120/85/80
Term
What are "Korotkov sounds"?
Definition
sounds heard in auscultation of blood pressure
Term
Define "Auscultation"
Definition
The procedure of listening for sounds within the body
Term
Why do you palpate the "Target Pressure"?
Definition
To avoid the auscultitory gap
Term
What is an "auscultatory gap"?
Definition
a cessation of the Korotkov sounds early in phase I which can confuse the determination of systolic pressure
Term
How do you apply the blood pressure cuff?
Definition
bladder over the artery 2 inches above antecubital
Term
How do you determine the correct cuff size for the patient?
Definition
1.2 X Limb Diameter (20% wider than limb diameter)
Term
What are the 3 types of manometers?
Definition
Mercury-gravity, aneroid, and automated
Term
What do you use on the stethoscipe to listen to low frequencies?
Definition
The bell
Term
What do you use on the stethoscipe to listen to high frequencies?
Definition
The diaphragm
Term
How should the earpieces of the stethoscope fit into your ears?
Definition
They should come into ear canals from behind
Term
At what rate should you deflate the cuff while taking a blood pressure?
Definition
2-3 mmHg per second
