Flashcards in Examination: Blood Pressure Deck (12)
What is BP?
Pressure of blood in the arteries as it is pumped around the body by the heart.
What influences BP?
Age, Exercise, anxiety, coffee, medications etc.
How is BP measured?
With a sphygmomanometer.
(BP) Step 1:
Prepare the Patient:
- explain the process
- uncovered upper arm
(BP) Step 2:
(BP) Step 3:
Select the appropriate cuff:
- Bladder length needs to be ~80% of the circumference of the arm and the width ~40%.
- If too small --> BP will be artificially high
(BP) Step 4:
Apply the cuff:
- Feel for the brachial pulse (medial aspect of the antecubital fossa)
- Wrap the cuff on the medial side of the arm with the arrow pointing to the brachial artery.
- Use a pillow to ensure the cuff is at the level of the heart.
(BP) Step 5:
Estimate SBP with palpation:
- feel for radial pulse and inflate cuff until that pulse dissapears
- release the cuff completely and wait 30 seconds
(BP) Step 6:
Listen to brachial pulse:
- Place diaphragm over brachial pulse and inflate the cuff to just above the SBP reading you got earlier
(BP) Step 7:
- Slowly deflate the cuff watching the pressure and listen for the auscultatory sounds.
(BP) Step 8:
Record the result and thank the patient
