Negative-Pressure Pulmonary Oedema
- Seen in the early postoperative period
- Due to forced inspiration in the presence of upper airway obstruction (e.g. from laryngospasm after extubation)
- After relief of laryngospasm, patients develop clinical and radiological features of pulmonary oedema
- Typically resolves over the course of a few hours with supportive care
- Cardiogenic pulmonary oedema should be excluded by clinical assessment, ECG and echocardiography
