Blood pressure Flashcards
1
Q
How do you start taking a blood pressure?
A
- wash hands
- introduce self
- confirm name & DOB
- explain procedure
- gain consent
2
Q
What is systolic BP?
A
pressure exerted during ventricular systole
3
Q
What is diastolic BP?
A
pressure maintained by the elasticity of the arterial walls during ventricular relaxation
4
Q
What is korotkoff I a sign of?
A
- tapping sound
- systolic pressure as the artery just opens
5
Q
What is korotkoff V a sign of?
A
- muffled/no tapping
- diastolic pressure as the artery is completely open
6
Q
What is a normal bp?
A
120/80
7
Q
What is grade 1 hypertension?
A
- mild
- 140/90
8
Q
What is grade 2 hypertension?
A
- moderate
- 160/100
9
Q
what is grade 3 hypertension?
A
- severe
- 180/110
10
Q
What is hypotension?
A
below the normal expected for an individual in a given environment
11
Q
What is hypotensive shock?
A
- systolic <90
12
Q
Explain the bp procedure
A
- patient sitting
- arm supported
- appropriate cuff size
- applies cuff
- palpates radial artery
- inflates cuff to est. systolic bp
- place diahragm over brachial artery
- identify korotkoff I
- identify korotkoff V
13
Q
How do you summarise a BP?
A
- state bp
- hypotensive/normotensive/hypertensive
- source of arm
- patient position
- “would measure 2x more”
- “would compare with patient standing”
