3 Factors needed for resp. function
what stimulates people without COPD to breathe?
what stimulates a pt with COPD to breathe?
The hypoxic drive...O2 levels
two ways O2 is carried in the blood
plasma measured by PaO2
oxyhemoglobin measured by SaO2
t/f: In Carbon monoxide poisoning you get abnormally high SaO2 levels
How do you measure SaO2?
Factors that influence respiratory function
Level of wellness
: respiratory disorders, CV disorders including left sided CHF
: scoliosis, obesity (there's a high correlation bt obesity and chronic bronchitis), aging
: narcotics and analgesics → ↓RR
: sedentary lifestyle doesn't encourage alveolar expansion; cigarette smoking active and passive
: Air pollution has high corr. with lung cancer; high altitudes = less O2. Dangerous for COPD who rely on hypoxic drive
