Question | Answer |
---|---|
RESP FAILURE IS DEFINED BY WHAT DIAGNOSTIC VALUES / TEST ............................p1353 | ABG'S = PaO2 < 50 - 60 & PaCO2 > 50 = indicators of resp failure |
how is resp failure indicated in COPD CTs ...p1353 | acute drop in blood O2 levels & increased Co2 levels |
causes of resp failure are | hypoventilation, impaired gas xchg, significant ventilation-perfusion mismatch |
types of dysfunction that cause impaired ventilation are .......................p1354 | airway obstruction, resp disease, neurological causes & chest wall injury |
types of dysfunction that cause impaired diffusion are .........................p1354 | alveolar disorders & pulmonary edema |
examples of airway obstruction are ......p1354 | laryngospasm, foreign body aspiration & airway edema |
examples of resp diseases are: | asthma & COPD |
examples of neurological causes of impaired ventilation are: | spinal cord injury, poliiomyelitis, gullain-barre, OD, stroke |
chest wall injuries that impair ventilation are | flail chest , pneumothorax |
alveolar disorders that impair diffusion are: | pneumonia, pneumonitis, COPD |
impaired diffusion r/t pulmonary edema is seen in: | heart failure, ARDS, near drowning |
ventilation perfusion mismatch is seen in what condition ...............................p1354 | pulmonary embolism |
examples of gas xchg disorders are: | ARDS, asthma, atelectasis, bronchiectasis, chronic bronchitis, COPD, cor pulmonale, cystic fibrosis, emphysema, pulmonary embolism, pulmonary HTN, resp failure, sarcoidosis, status asthmaticus |
