An artifact induced by negative pressure ventilation

Chest. 1992 Feb;101(2):563-5. doi: 10.1378/chest.101.2.563.


This report draws attention to an artifact that influences the qualitative information gained from respiratory inductance plethysmography during negative pressure ventilation with a cuirass. This artifact may prevent identification of upper airway obstruction, a manageable complication of this mode of ventilation.
