Successful use of continuous negative chest-wall pressure (CNP) therapy is reported in management of progressively severe hypoxemia due to aspiration pneumonitis, in a spontaneously breathing child. Application of CNP therapy produced a sustained improvement in arterial oxygenation that permitted an early reduction in FIO2 requirement to a safe level. In addition, this method of ventilatory assistance eliminated the need for endotracheal intubation and use of muscle relaxants and sedatives.
