- respiratory rate
- vasodilation
2
Q
decreased physiological effects of heat
A
- BP
- muscle activity
- blood to internal organs
- blood flow to resting muscle
- stroke volume
3
Q
increased physiological effects of cold
A
- blood flow to internal organs
- cardiac output
- stroke volume
- arterial blood pressure (shivering occurs when core temp drops)
4

5
Q
What MHz should be used for US for superficial vs deep layers
A
3 MHz for superficial layers (1-2.5 cm deep)
1 MHz for deep layers (up to 6 cm deep)
6
Q
