Term
|
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
|
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 |

|
Definition
They should come into ear canals from behind |
