Loudin - ARDS

Question 1

Oxygenation of patient is determined by ?

Answer 1

Mean airway pressure

This is PEEP on vent = positive end expiratory pressure

Question 2

How do you determine CO2 output on vent?

Answer 2

Minute ventilation -> change tidal volume and respiratory rate to change minute ventilation

MV = TV x RR

Question 3

Management strategies for ARDS:

Answer 3

Low tidal volume ventilation

Permissive hypercapnia

Sedation

Open lung ventilation

High PEEP
