We speculated that clinicians might generate very high airway pressure during manual ventilation (much higher than the pressure delivered by a mechanical ventilator), and that the high airway pressure causes alveolar recruitment and thus improves oxygenation. Such high pressure might injure alveoli in some patients. METHODS: We tested the hypothesis that manual ventilation may involve substantially higher pressure than is delivered by a mechanical ventilator. We asked experienced respiratory therapists to manually ventilate a lung model that was set to represent several typical clinical scenarios. RESULTS: We found that the peak airway pressure generated by the therapists was sometimes in excess of 100 cm H2O. CONCLUSIONS: The high airway pressure during manual ventilation would be considered extreme in the context of conventional mechanical ventilation, which raises questions about whether manual ventilation causes barotrauma.}, issn = {0020-1324}, URL = {https://rc.rcjournal.com/content/50/3/340}, eprint = {https://rc.rcjournal.com/content/50/3/340.full.pdf}, journal = {Respiratory Care} }
