The oxygen saturation was 95%. Other physical and cardiovascular examination was unremarkable. The patient had never been evaluated for any cardiorespiratory illness in the past. The chest radiograph showed right-sided pleural effusion with an underlying mass lesion. Tube thoracostomy was done and confirmed haemothorax.
