Organ dysfunction Flashcards
1
Q
What is the calculation for mean arterial pressure?
A
systemic vascular resistance x CO
2
Q
Which is a serious complication of iatrogenic vasconstriction in the treatment of sepsis?
A
necrosis of digits
3
Q
What is the cause of type 1 respiratory failure?
A
ventilation/perfusion mismatching, functional loss of alveoli leads to shunting
4
Q
What is the cause of type 2 resp failure?
A
hypoventiation or increased dead space, leads to decreased alveolar ventilation, V/Q mismatch, and therefore reduced CO2 clearance
5
Q
What are the risks of ventilation?
A
ventilator associated lung injury, intubation associated pneumonia, respiratory muscle deconditioning, effects of sedation (delerium)
