37-Year-Old Tracheostomized Woman With Overdistended Tracheostomy Cuff and Difficulty Ventilating.

Abstract

A 37-year-old woman with a medical history of myasthenia gravis resulting in progressive respiratory failure requiring continuous mechanical ventilation via tracheostomy, as well as multiple cardiac arrests leading to severe anoxic brain injury, was brought to the hospital from a nursing home because of difficulties with ventilation and oxygenation. On presentation to the ED, the patient was found to be agitated and tachypneic on a ventilator, generating low tidal volumes despite elevated peak airway pressures. Before the current presentation, the patient had been mechanically ventilated at a long-term acute care facility for the past 5 years. More recently, staff has noted intermittent loss of tidal volumes, temporarily responding to overinflation of tracheostomy cuff. Additionally, the tracheostomy tube was exchanged for an extra-long tracheostomy tube to improve tidal volumes; however, the problem persisted, prompting the current presentation.
