In mechanical ventilation, the artificial airway can create a considerable amount of imposed work of breathing (WOB).1,2
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.
