In mechanical ventilation, the artificial airway can create a considerable amount of imposed work of breathing (WOB).([FOOTNOTE=Fabry B, Guttman J, Eberhard L, Wolff G.

The Puritan Bennett™ Tube Compensation software option is a spontaneous breath type that accurately overcomes imposed WOB from endotracheal and tracheostomy tubes. It compensates for the resistance across the artificial airway.
The easy-to-implement option is engaged after four variables are entered into the ventilator. The ventilator adjusts up to 200 times a second to a patient’s spontaneous breaths.
Key in the size of endotracheal tube or tracheostomy tube in place, and the ventilator automatically calculates the correct support.
Patients can experience a lower work of breathing with the Tube Compensation software option when compared to CPAP or T-piece breathing.,
Patients who breathe spontaneously through an endotracheal tube while the Tube Compensation software option is engaged show increased signs of comfort compared to CPAP or T-piece breathing.
A patient’s ventilatory drive and flow can change dramatically depending on whether the patient is asleep or awake, calm or agitated. The Tube Compensation software can vary pressure to compensate for flow demand.
