FSHN 450-3 copd
| Question | Answer |
|---|---|
| Compliance | ability of lungs to contract and expand (highest at moderate lung volumes) |
| Increased compliance | (decreased rebound) decreased expiratory flow, low rate of deep inspirations |
| Decreased compliance | (increased rebound) rapid shallow inspirations |
| Bronchitis | chronic inflammation and production of mucous which may lead to fibrosis |
| Fibrosis | decrease in compliance (increased rebound) due to thickening and scarring of bronchial walls |
| 2 main causes of COPD | smoking, hereditary deficiency of alpha-1-protease inhibitor (elastase uninhibited) |
| diagnosis of COPD | forced expiratory volume after 1 second/forced vital capacity <70-75% |
| medical complications of COPD | right side heart failure and lower extremity edema |
| polycythemia | body’s attempt to adjust decreased amounts of oxygen by increasing RBC production (clogs small blood vessels) |
| sputum | mucous from COPD |
| hypomagnesia and hypophosphatemia effect | decreased respiratory muscle strength |
