A nearly fatal tracheal obstruction resulting from a transtracheal oxygen catheter.

Tracheal perforation. A complication associated with transtracheal oxygen therapy.

A 73-year-old woman with a transtracheal oxygen catheter in place developed sudden onset of respiratory distress and subcutaneous emphysema. Bronchoscopy revealed the presence of three posterior tracheal wall perforations and a blind pouch arising from one of the perforations. Subsequent bronchoscopies revealed complete healing of the perforations. We believe that these perforations occurred du...

Respiratory failure and cor pulmonale associated with tracheal mucoid accumulation from a SCOOP transtracheal oxygen catheter.

Transtracheal oxygen (TTO) delivery for patients with chronic hypoxemia has been used increasingly since its introduction in 1982. Most complications have been relatively minor and usually occur in conjunction with catheter placement. This report describes two patients with long-term catheter use who developed increasing respiratory failure and cor pulmonale, at least in part, due to a large tr...

Transtracheal oxygen, nasal CPAP and nasal oxygen in five patients with obstructive sleep apnea.

The effect of transtracheal oxygen administration by means of a 9-French (2.7 mm) percutaneous catheter was assessed in five patients with severe obstructive sleep apnea. We hypothesized that the delivery of oxygen below the site of airway obstruction should reduce the arterial oxygen desaturation during apneas and hypopneas, thereby increasing respiratory stability. Standard sleep and respirat...

Oxygenation and ventilation during cardiopulmonary resuscitation utilizing continuous oxygen delivery via a modified pharyngeal-tracheal lumened airway.

Use of continuous transtracheal oxygen delivery systems combined with rhythmic chest compressions can provide excellent oxygenation and ventilation during cardiopulmonary resuscitation. However, occasional displacement of the transtracheal catheter results in life-threatening pneumomediastinal complications. We investigated using the pharyngeal lumen of a pharyngeal-tracheal lumened airway (PtL...

Airway obstruction by a mucus ball from a transtracheal oxygen catheter.
