Answer 1

ARDS is defined by 4 criteria:

1. The condition must be acute (< 7 days)
2. The findings are not solely explained by cardiogenic pulmonary edema
3. The chest X-ray must have bilateral opacities

Question 2

A partir de qual PaO2 / FiO2 é considerada ARDS ?

Quanto que é MILD ; MODERATE ; SEVERE ?

Answer 2

PaO2 / FiO2 must be < 300

1. Mild ARDS is a PaO 2 /FiO 2 ratio of 200-300
2. Moderate ARDS is 100-199
3. Severe ARDS is < 100

Question 3

Se há uma Pip de 35 , Pplateu de 32 o que pode se interpretar ? Qual seria o problema em termos patofisiologicos ?

O que pode ser feito ?

Answer 3

There is a minimal difference between the PIP (35 cm H 2 O) and the Pplat (32 cm H 2 O) indicating that the patient has only a COMPLIANCE problem without a resistance
problem.

In the image below, an inspiratory hold has been performed, providing a Pplat of 32. This
tells us two things:
1. There is a minimal difference between the PIP (35 cm H 2 O) and the Pplat (32 cm
H 2 O) indicating that the patient has only a compliance problem without a resistance
problem.

2. The Pplat is too high. The tidal volume should be lowered to 5 ml/kg PBW and reassessed.
