Patients die due to poor product design. Ventilator-dependent tracheostomy patients frequently experience accidental ventilator disconnect between the tracheostomy tube and the ventilator; a deadly problem known clinically as "pop-off". This issue occurs multiple times per day, sometimes every hour, for some patients. Hospital clinicians have stated that ventilator-dependent patients must stay in the Critical Care Unit (CCU) or the Intensive Care Unit (ICU) to have someone within reach to immediately reconnect the breathing tube to the ventilator when it pops off. If not reconnected within two to four minutes, the patient may die, or suffer catastrophic (permanent) lung and/or brain injury.
