Respiratory failure

empyema

myocarditis pericarditis hypotension septicaemia Atrial fibrillation
jaundice
type 1
venous blood bypasses ventilated alveoli (e.g. right to left cardiac shunt)
under-ventilated alveoli
60% high-flow oxygen
PaCO2 levels
empyema
COPD
normally PaCO2 is major driving force behind respiratory drive
COPD hypoxia is a major drive for rr and pulmonary venous constriction
o2 therapy reduces hypoxia
therefore reduced respiratory drive
REDUCED HYPOXIC CONTROLLED VASOCONSTRICTION
VQ mismatch as increased blood flow to poorly ventilated areas
therefore increase in CO2
fluid challenge
250mL colloid over 15 mins
increase in cardiac output of 10-15%
pleural inflammation
fluid exudation
accumulates faster than reabsorbed
