Acute Respiratory Distress Syndrome Flashcards
what are the 3 inclusion criteria for Acute Respiratory Distress Syndrome?
abrupt dyspnea within 7 days of insult
hypoxemia
diffuse lung infiltrates
what are the three phases of ARDS?
exudative
proliferative
fibrotic
what days is the exudative phase?
1-7
what occurs in the exudative phase of ARDS?
protein-rich edema accumulates in alveolar spaces and surfactant is lost
what is required when a patient is in exudative phase of ARDS? - except COVID patients
intubation and ventilation
what days is the proliferative phase?
7-21
what occurs in the proliferative phase of ARDS?
type II pneumocytes grow and synthesize new surfactant
what days is the fibrotic phase of ARDS?
over day 21
what occurs in fibrotic phase of ARDS?
edema and inflammatory exudate leads to alveolar and interstitial fibrosis
what are 3 symptoms of ARDS?
Retractions
Dysnea
Sounds - rales
what would ARDS look like on a chest xray?
diffuse bilateral infiltrates
costophrenic angles still present
what would ARDS look like in a chest CT?
dependent alveolar edema
what is the treatment for ARDS? (4)
treat underlying cause
intubation (most)
positive pressure ventilation
prone position
what should be restricted in patients with ARDS? (2)
fluid intake
diuresis
