Critical care medicine is the "health care provided to a critically ill patient during a medical emergency or crisis".[1]
Monitoring
Swan-Ganz catheterization
Oxygenation
- Alveolar-arterial oxygen (A-a) gradient (alveolar-arterial oxygen difference - AVO2D)
The A-a gradient is harder to calculate, but accounts for changes in ventilation as measured by the partial pressure of carbon dioxide.
- PaO2/FiO2 ratio (PF ratio)
This measure is easier to calculate. Comparative studies suggest it correlated better with pulmonary shunts.[2][3][4]
Preventing complications in critically ill patients
Selective gastrointestinal decontamination
Systematic reviews conclude that selective decontamination of the digestive tract may reduce morbidity in critically ill patients[5][6][7] although some randomized controlled trials have[8][9][10] and others have not found benefit[11].
Preventing gastrointestinal tract ulceration
Preventing deep venous thrombosis
Preventing healthcare-associated pneumonia
