High-frequency ventilators are dependent on patient airway caliber for adequate volume delivery. A change in airway diameter (e.g., by accumulation of secretions or by migration of the tip of the ETT against the tracheal wall) may significantly reduce delivered volumes. The first step should be a quick assessment of chest wall movement. If chest wall motion is substantially decreased, a brief use of manual ventilation while troubleshooting the airway and ventilator may dramatically improve the situation. Steps should be taken to correct any problems with the ETT lumen or position (e.g., suctioning, chest radiograph).
