Open Access Abstract Introduction To determine whether subjecting patients to 100 ml of additional dead space after a 1 20-minute weaning trial could predict readiness for extubation. Methods This was a prospective non-randomised pilot study in an intensive care unit at a university hospital with 14 beds. It included all non-tracheostomised patients with improvement of the underlying cause of acute respiratory failure and those with no need for vasoactive or sedative drugs were eligible. Patients fulfilling the Consensus Conference on Weaning extubation criteria after 120 minutes spontaneous breathing n 152 were included. To the endotracheal tube 100 cc dead space was added for 30 minutes. Patients tolerating the test were extubated those not tolerating it received six hours of supplementary ventilation before extubation. The measurements taken and main results were arterial pressure heart rate respiratory rate oxygen saturation end-tidal carbon dioxide and signs of respiratory insufficiency were recorded every five .
