Adjust Effective Trigger Sensitivity in the Presence of a Leak
The Puritan Bennett™ Leak Compensation software adjusts effective trigger sensitivity in the presence of a leak during both noninvasive and invasive ventilation. Adjusting trigger sensitivity can help keep the ventilated newborn at a more desirable work of breathing.
In two recent studies, the Puritan Bennett™ 840 ventilator with Leak Compensation software outperformed all other ventilators included in the studies.8
In both studies, leak compensation was compared in five acute care ventilators (the Maquet SERVO-i®*, Dräger V500, Covidien Puritan Bennett™ 840 ventilator, Philips Respironics V60®*, and Hamilton C3), using an ASL5000 lung simulator.8
Invasive Ventilation Model8
- The study authors concluded that only the Puritan Bennett™ 840 and Philips Respironics®* V60 ventilators exhibited synchronization following all increasing and decreasing leak scenarios.
- The Puritan Bennett™ 840 ventilator required fewer breaths to synchronize to increasing and decreasing leaks compared with the Philips Respironics®* V60 ventilator (p < 0.0001).
Noninvasive Ventilation Model8
- The study authors concluded that, with the exception of the Dräger V500, all ventilators exhibited synchronization to increasing and decreasing leaks. The Puritan Bennett™ 840 ventilator required fewer breaths to synchronize to increasing and decreasing leaks compared with all other ventilators in this study (p < 0.0001).
By effectively managing airway leaks, Puritan Bennett™ Leak Compensation software can help clinicians provide the right ventilation even when faced with rapidly changing patient conditions, supporting the clinicians’ efforts to keep babies safe and comfortable.
