Web13 de jun. de 1996 · The respiratory response to CO 2 during pressure-support ventilation (PSV) was studied in 16 conscious normal humans. The subjects breathed through a mouthpiece connected to a ventilator in PSV mode, with pressure set to the highest comfortable level for each subject (10.1 ± 0.6 cm H 2 O, mean ± SE).
