We hypothetised that the rate of pre‐oxygenation could be altered by the increase in lung volume and airflow obstruction observed in emphysema. End‐tidal oxygen concentration was monitored, using a paramagnetic oxygen analyser, during 10‐min pre‐oxygenation (tidal breathing of 100% oxygen) in 10 nor...
