Initial laboratory test results revealed a haemoglobin of 6.6 g/dl and the chest x-ray (Fig. 1A) was consistent with bilateral alveolar infiltrates. Over the next 2 hours, she continued to have haemoptysis and worsening hypoxaemia with increasing bilateral infiltrates on CT scan (Fig. 1B). A chest x-ray (Fig. 1C) obtained the following day showed worsening airspace disease. Her chest x-ray (Fig. 1D) and ABG also showed significant improvement (pH of 7.48, a Paco2 of 36, a Pao2 of 267 and an HCO3 of 27 on an FIO2 of 0.5 and PEEP of 8).
