thru R. atrium → R. ventricle and is pushed into pulmonary arteries in the lungs →after getting O2 → blood goes back to the heart thru pulmonary veins → L. atrium → L. ventricle → to the rest of the body.

Systole
HEART MUSCLE CONTRACTS
* blood pumps from chambers → arteries * S1: max. point of contraction
9
New cards
Diastole
HEART MUSCLE RELAXES
* allows chambers to fill with blood * S2: relaxed phase/refills with blood
10
New cards
S1
mitral & tricuspid closure (LUB)
* heard at the apex * max. point of contraction
11
New cards
S2
aortic & pulmonary closure (DUB)
* heard at L. sternal border * relaxed phase/refills with blood
* rate, rhythm, equality, amplitude BILATERALLY * +2 = normal
31
New cards
Grading scale for amplitude of peripheral pulses
0: absent
1: diminished/ weak
2: normal/brisk/expected
3: bounding

What is the purpose of the Allen test?
find out which side of PT body has better perfusion/arterial flow
33
New cards
How do you preform Allen Test ?
1. Occlude BOTH ulnar and radial artery in ONE HAND 2. ask PT to make a fist several times 3. have PT open hand 4. release ULNAR artery pressure only
34
New cards
Normal finding for Allen test
hand regains blush within **2-5 seconds**
* indicates __NORMAL CIRCULATION__
35
New cards
When do we evaluate Arterial Supply to Legs?
we evaluate if we suspect arterial deficit
36
New cards
How to evaluate Arterial Supply to Legs?
1. place PT lying down with **BOTH LEGS about 60°** up __(until max. pallor of feet develop)__ 2. have PT **flex ankles UP AND DOWN** to __drain venous blood__ 3. ask PT to sit up and dangle legs over side of bed 4. compare **BILATERALLY**
37
New cards
Normal finding for Evaluation of Arterial Supply to Legs
return of pinkness → **10 seconds**
filling of veins in feel and ankle → **15 seconds**
38
New cards
Abormal finding for Evaluation of Arterial Supply to Legs
* slow return of color & filling of veins * RUBOR (arterial insuffenciency)
