Physiologic Exams Flashcards
(47 cards)
How should you prepare the patient to start the examination used to assess the venous refill time using photoplethysmography
seated at the edge of the table with lower legs dangling, sensor placed at medial malleolus
What are the average treadmill settings utilized in exercise testing
2mph at 12% grade
Where is the recommended placement for the pneumatic cuff when using a rapid cuff inflator to evaluate the distal femoral vein and GSV
upper calf
A patient presents with a history of recurrent upper extremity DVT due to paget schroetter syndrome. The referring physician ordered a PVR exam of the upper extremities instead of a venous doppler exam of the upper extremities. Why
to rule out thoracic outlet syndrome
The upslope of a waveform is called-
The downslope is called-
anacrotic, catacrotic
You are preparing for a lower extremity segmental pressure exam on a patient with leg pain. She was admitted to the hospital 2 days ago due to extensive lower extremity DVT. How will you proceed
obtain doppler waveforms and toe-brachial indices
You are evaluating a patient with suspected Raynaud disease using PPG. After obtaining a baseline tracing, you place the hand in cold water for 2 minutes. Once the hand is removed, PPG sensors are reapplied to the fingertips. Which of the following correctly describes normal results for this exam
waveforms return to baseline within 5 minutes after removing the hand from the cold water
What is the normal change in flow velocity in response to releasing the cuff during reactive hyperemia
increase to more than double the resting flow velocity
Lower extremity arterial segmental pressure exam resulting in a post exercise basal pressure recovery time of ________ suggests single level disease. Longer than 6 minutes is
2-6 minutes, multi level disease
Lower extremity arterial segmental pressure exam results in a post exercise basal pressure recovery time of 2 to 6 minutes which suggests
single level stenosis
When performing a lower extremity venous doppler for insufficiency, a minimum of ___________ between augmentation maneuvers is recommended
30 secs
A normal lower extremity arterial response to reactive hyperemia is
<35% drop in ankle pressures that return to normal within 1 minute
What setting on the photoplethysmography system should remain constant during an extremity arterial evaluation and if it is adjusted it must be documented on the tracing
size control
What patient would benefit from an exercise segmental pressure exam
patient with claudication and a resting ABI of 0.95
What technique can be used to assess the presence and timing of reflux in multiple vessels simultaneously
color doppler
Patients experiencing claudication typically have an ABI of
0.5-0.9
The Adson maneuver is helpful in the diagnosis of what vascular disorder
thoracic outlet syndrome
An abnormal penile/brachial index will be
<0.65
When evaluating suspected thoracic outlet syndrome, a PPG exam can be performed with the sensor placed on the ______ or a doppler exam can be performed with the transducer placed _________
2nd digit, on the radial artery
An arterial duplex exam demonstrates monophasic flow in the popliteal and calf arteries. The bilateral ABI calculations are over 1.0. What type of testing can be used to better evaluate the pressures in the lower extremities in this patient
digit plethysmography
What is a normal response from the capillary beds of the feet and ankles after 5 minutes of vigorous exercise
vasodilation
Which extremity arterial evaluation technique can be describes as the placement of multiple cuffs around the extremity that measures the volume changes beneath them
pulse volume recording
The normal pressure in the lower extremity digits is normally at least _______ of the brachial pressures
60%
If the systolic brachial pressure is 116mmHg, the toe pressure would be considered normal if it is _______ or greater
70mmHg
