- High airway pressures in the intubated patient can signify the presence of a life-threatening emergency.
- The underlying cause is either with the ‘man or the machine’ (patient versus equipment).
- A structured approach to this problem is essential.
- inappropriate settings
- ventilator malfunction
- pooling of condensed water vapour
- wet filters causing increased resistance
- Endotracheal tube
- displacement, e.g. endobronchial intubation
- obstruction with foreign material
- bronchospasm (e.g. asthma)
- decreased compliance
- lung (e.g. collapse, consolidation, pulmonary edema)
- pleural (e.g. pneumothorax, pleural effusion)
- chest wall (e.g. abdominal distention, kyhposcoliosis, obesity)
- patient-ventilator dysynchrony, coughing
