Measuring The Blood Pressure Flashcards
A small bp cuff will affect bp reading how
Small bp cuff will lead to overestimation of bp - like in obese pxs
What is the ideal cuff size
Length and width should be 80% and 40% of arm circumference, respectively
The cuff should be deflated by
3 mmhg/ sec
Column or dial should be read to the nearest
2 mmHg
When is the auscultatory gap most likely to occur
In older, hypertension pxs with target organ damage
Korotkoff sounds may be heard all the way to 0 mmHg among what pxs or conditions
Pregnant
Severe AR
Presence of large fistula
Phases 4 and 5 should be noted
How should bp in the 2 arms differ
Only by 10mmHg
What will you suspect if you have a bp differential of more than 10
Subclavian artery disease
Supravalvular aortic stenosis
Aortic coarctation
Aortic dissection
If systolic leg pressures exceed arm pressures by more than 20mmHg, what will you suspect
Severe AR (Hill sign) Extensive and calcified lower ext PAD
How is leg BP obtained
Using largebthighbcuffs with auscultation at the popliteal artery or
Standard large cuffs at the calf with auscultation or palpation of the post tibial artery
Best method for pxs suspected to have white coat hon
Ambulatory bp monitoring
When will you suspect masked hypertension
Measurement of lownor normal bp in pxs with evidence of hypertensive end organ damage
Ie Severe PAD
Describe orthostatic hpn
A fall in bp of more than 20 mmhg systolic and more than 10 mmhg diastolic in response to moving from supine to standing within 3 mins
Lack of compensatory tachycardia - suugetsive of autonomic insuffiency can occur in
Dm and Parkinsons disease
The heart rate, blood pressure respobse to standing also depends on
Age, hydration, medications, foos, conditioning
Ambient temperature and humidity
