IMPLICATIONS: With a bellows leak in an O2-driven Ohmeda 7810 ventilator, room contamination occurred but inspired oxygen fraction (Fio2), airway pressure, and tidal volume (Vt) were unaffected. Room contamination is likely in designs without scavenging of drive gas. Fio2, airway pressure, and Vt results may not apply to ventilators, e.g., Drager AV-E, where drive gas contains entrained air.
