Q

Platelets

A

help to clot blood

17
Q

why would Hb levels increase (2)?

A
  1. dehydration

2. polycythemia

18
Q

WBC count

A

immune system

19
Q

INR

A

test for people who are on blood thinners (Coumadin)

20
Q

PTT

A

“partial thromboplastin time”

Test to see how long it would take blood to clot

21
Q

HR normal values

A

60-100 bpm

22
Q

BP normal values

A

120/80 mmHg

23
Q

Respiratory Rate values

A

12-20 breaths/min

24
Q

SaO2 values

A

“saturated oxygen”

95%

25
Q

as the cerebral motor cortex fires in anticipation/initiation of exercise, what happens to cardiac output

A

increases

26
Q

cardiac output

A

volume of blood ejected from the ventricle

- either the L.V. to the Aorta OR the R.V. to the pulmonary arteries

27
Q

Cardiac Output equation

A

CO=HR x SV

28
Q

Heart Disease: Class 1

A

no limits

max met=6.5

29
Q

Heart Disease: Class 2

A

slight activity limit
max met=4.5
comfortable usually at rest and with less than ordinary activities
- may have shortness of breath, palpatations, or heavy breathing

30
Q

Heart Disease: Class 3

A

marked limitation
max met=3.0
usually comfortable at rest but ordinary activity may cause pain, palpatation, or shortness of breath

31
Q

Heart Disease: Class 4

A

inability to carry out activity w/o discomfort
max met=1.5
discomfort with any activity
- pain, palpatations, heavy breathing

32
Q

hemorrage does what to arterial pressure?

A

decreases
