Noninvasive interface for transtracheal mechanical ventilation for patients with severe cervical spine deformity

This article describes a custom-molded patient-to-ventilator interface that permits mechanical ventilation via a tracheostomy site for patients for whom tracheostomy tubes can not be used because of severe cervical deformity. The nocturnal delivery of intermittent positive-pressure ventilation resulted in normalization of oxyhemoglobin saturation and end-tidal CO2 and alleviation of symptoms of alveolar hypoventilation. Thermoplastic patient-ventilator tubing interfaces can be constructed to permit ventilatory assistance for patients with tracheostomies who can not use tracheostomy tubes.
