Gerontology Module 5

What is the formula for VO2? • VO2 = CO x (a - vo2 diff) – VO2 = oxygen consumption – CO = cardiac output; product of HR and SV (stroke volume)
What is the formula for arteriovenous oxygen difference? (a - vo2 diff) --> this value decreases with age, Indicating peripheral tissues receive less O2 for energy
How does oxygen consumption change with age? ↓ peripheral blood distribution, ↓ arterial oxygen, ↓ hemoglobin levels, and a loss of activity in tissue enzyme systems
What is cardiac output a product of? HR and SV -• Normal CO at rest is 4 to 6 liters per minute – Increases linearly with workload
What is an increase in CO with exercise due to? an increase in both HR and SV
What contributes to age-related decline in VO2max? A decline in max CO - – Factors include body size, physical fitness level, and condition of heart structures involved with CO
What is the amount of blood ejected by the left ventricle at each heartbeat? Stroke Volume – Difference between end-diastolic and end-systolic blood volume
What impacts SV response? Body position – SV is lower in sitting or standing versus in supine
What is the Frank-Starling mechanism? SV increases with an increase in the volume of blood filling the heart (the end diastolic volume) when all other factors remain constant. -• Increasing SV during heavy exercise
