Snippet: Patient Ventilatory Effort: While it is important that patients not spontaneously breathe for the PReVentS protocol, it is also important that the system be robust to unanticipated ventilatory effort. Depending upon how ventilatory efforts align with the ventilator cycle, the effects on the spontaneously breathing patient will be variable (Appendix S1).

Document: Patient Ventilatory Effort: While it is important that patients not spontaneously breathe for the PReVentS protocol, it is also important that the system be robust to unanticipated ventilatory effort. Depending upon how ventilatory efforts align with the ventilator cycle, the effects on the spontaneously breathing patient will be variable (Appendix S1). In general, the spontaneously-breathing patient's tidal volumes will increase, and room air may be entrained through the negative pressure relief valve into that patient's circuit. We anticipate that there will be no effect on the other patient's ventilation or FiO2. Respiratory effort will trigger the high VTe alarm.
