Q

fraction of inspired oxygen

17
Q
A

Acute onset
CXR +ve
PCWP
Refractory hypoxaemia (PaO2:FiO2)

18
Q
A

fraction of inspired oxygen

19
Q
A

comparison between [O2] in blood and the [O2] that is breathed

20
Q
A

less than 200

between 200-300 indicates acute lung injury

21
Q
A

low tidal volume mechanical ventilation

22
Q
A

reduced lung compliance = high pressure –> potential pneumothorax

23
Q
A

trigger (shock/trauma)
widespread inflammation/release of inflammatories
damaged alveoli/reduced surfacant

24
Q
A

BILATERAL (widespread inflammation)

25
Q
A

basically anything

Sepsis –> malaria –|> raised ICP
