T2 - AF, ARDS, PE, Chest Trauma (Josh) Flashcards
Acute Respiratory Failure (ARF):
Which type is Type I?
Which type is Type II?
Oxygenation Failure
Ventilatory Failure
Acute Resp. Failure (ARF):
What are ABGs in Type I?
PaO2 less than 60 (hypoxemia is hallmark sign)
SaO2 less than 90
PCO2 35-45 (normal)
Acute Resp. Failure (ARF):
What is etiology of Type I?
Breakdown of O2 transport from alveolus to the arterial flow
V/Q Mismatch
- air movement adequate but perfusion is decreased
Acute Resp. Failure (ARF):
What do ABGs look like with Type II?
PCO2 greater than 45 (Hypercapnea)
pH less than 7.35 (acidic)
Acute Resp. Failure (ARF):
Etiology of Type II
Musculoskeletal or anatomical lung dysfunction or suppression
V/Q Mismatch:
- air movement inadequate but perfusion ok
Acute Resp. Failure (ARF):
COPD, Head Injuries, Narcotic Overdose, ALS, Guillain-Bare, and Muscular Dystrophy are causes of which Type of ARF?
Type II (Ventilatory Failure)
Acute Resp. Failure (ARF):
Pneumonia, Aspiration, Atelectasis, and PE are causes of which type of ARF?
Type I (Oxgenation Failure)
