Q

What is orthostatic/postural hypotension

A

Dizziness and low blood pressure when going from reclining to upright position

17
Q

What is the ideal cuff size

A

Should be 40% of the circumference of the midpoint of the limb and bladder in cuff should encircle 80% of the limb

18
Q

What are some factors influencing blood pressure

A 
Age
Gender
Medications
Diurnal variation
Position
Sympathetic stimulation
Exercise
Weight
Ethnicity
Smoking
19
Q

What is the rationale for doing the 2 step method

A

Auscultory gap- a period of abnormal silence or diminished intensity during one of the korotkoff sound phases. During the silence, the pulse wave is palpable but not audible. Exact cause or mechanism is unknown

20
Q

Which patient usually have an auscultory gap

A

Hypertensive patients and those with arteriosclerotic heart disease
