10A: Aging Flashcards
1
Q
What element of the CV system decrease with aging?
A
- Vascular elasticity
- Adrenergic response to exercise
- Rate of calcium pump
- Cardiac muscle twitch force
- Rate of ATP activity
- Lean body mass
2
Q
What are three additional CV changes with age?
A
- Left ventricular hypertrophy
- Prolonged time to peak force of cardiac muscle
- Diastolic dysfunction
3
Q
What do CV changes with aging lead to?
A
- Decreased heart force
- Disturbances to cardiac cycle
- Peripheral changes
4
Q
What are four normal pulmonary changes with aging?
A
- Decreased peripheral chemoreceptor sensitivity
- Decreased thoracic cage mobility and lung tissue compliance
- Arthritic changes
- Increased O2 demand for respiratory muscles
5
Q
What is the result of normal changes due to aging on the pulmonary system?
A
Increased V/Q mismatch
6
Q
What are signs and symptoms of pulmonary changes due to aging?
A
- SOB and DOE
- Decreased endurance
- Rib and thoracic pain
- Postural changes
7
Q
How do you treat respiratory pathology due to aging?
A
- Breathing strategies
- Thoracic mobility
- Functional endurance
- Energy conservation
- Supplemental O2
