Physical inactivity can be deadly for older adults.
How does aging affect the cardiovascular system? Select the 2 most appropriate answers:
Decreases Max HR, Max/Resting SV, and Max/Resting CO.
Increases Max O2 Consumption, Exercise/Resting BP.
Decreases Max/Resting HR, Max/Resting SV, and Max/Resting CO.
Decreases Max HR, Max SV, and Max CO.
Decreases Max/Resting HR, Max SV, and Max CO.
Decreases Max/Resting HR, Max SV, and Max/Resting CO.
No Effect on HR, SV, or CO

Decreases Respiratory Rate.
What can cause cardiac arrhythmias in the older adult?
Loss of pacemaker cells in the right atrium and an increase in fibrous tissue in the conducting pathways.
Decreased parasympathetic activity.
Increased sympathetic activity.
Increased cardiac output.
How might normal aging changes in lung tissue influence gas exchange?
Loss of alveolar-capillary interface
Enlargement of alveolar wall and overall size
Thickening of Blood
Reduced blood volume
Increased blood pressure
Decreased rib-cage mobility and strength of respiratory muscles lead to decreased lung volume in the older adult.
COPD can result in limited pulmonary reserve due to decreased lung volume and/or obstruction of airflow.
Select the 2 appropriate exercise intensities for elderly patients.
Healthy elderly: 50-70% of max HR
Patients with Caridopulmonary conditions: 20-30% of max HR
Healthy elderly: 70-85% of max HR
Healthy elderly: 30-50% of max HR
Patients with Caridopulmonary conditions: 30-50% of max HR
Patients with Caridopulmonary conditions: 50-70% of max HR
