Helping to Protect Your Most Vulnerable Patients from Leak-Related Complications

The new Puritan Bennett™ 980 ventilator was designed with the challenges of safe and effective ventilation in mind. Automatically detecting and compensating for fluctuating leak sizes, Puritan Bennett™ Leak Sync software helps clinicians manage patients’ work of breathing.

Breathing circuit leaks can cause a ventilator to erroneously detect patient inspiratory efforts (called autotriggering) or delay exhalation in pressure support. Patient interfaces, such as masks and uncuffed endotracheal tubes, are particularly prone to significant leaks. Inaccurately declaring inspiration or exhalation can result in patient-ventilator asynchrony and increased work of breathing.

Leak Sync software accurately quantifies instantaneous leak rates in adults, pediatric and neonatal patients during invasive or noninvasive ventilation. It compensates for leaks up to 65 L/min in adults, 40 L/min in pediatric patients and 15 L/min in neonates.

Product Features

The Puritan Bennett™ Leak Sync software is similar to the Leak Compensation software on the Puritan Bennett™ 840 ventilator, but has been expanded to be used with VC+ and VS. Leak compensation software has been proven to synchronize faster than other leading ventilators to increasing and decreasing leaks.1

The Puritan Bennett™ 980 ventilator with Leak Sync technology is able to:

  • Automatically compensate for leaks up to 65 L/min in adults, 40 L/min in pediatric patients and 15 L/min in neonates, helping to reduce trigger and cycle asynchronies
  • Quantify and compensate for new leaks or changes in leak rate within approximately three breaths.2
  • Display the percentage of volume lost to the leak (% LEAK), leak rate (LEAK L/min) and leak volume directly on the graphical user interface (GUI)

Leak Sync software works with the following breathing strategies:

Airleaks Can Make Safe and Effective Neonatal Ventilation a Challenge

Clinicians strive to support healthy gas exchange and maintain clinical stability in NICU babies, while also protecting them from lung injury.3,4 Gas leaks around the endotracheal or tracheostomy tube can make this a challenge. Considerable leaks around the airway interface are common in newborns with the use of uncuffed endotracheal and tracheostomy tubes and airway masks.5

When breathing circuit leaks are not managed effectively, they can lead to6,7

  • Inappropriate breath triggering and cycling
  • Inadequate ventilation
  • Inaccurate patient data

Detecting and responding to leaks is an important initiative that can improve treatment and reduce the infant’s work of breathing.8

The Puritan Bennett™ 980 neonatal ventilator was designed to help protect your most vulnerable patients from leak-related complications. Puritan Bennett™ Leak Sync software is available to automatically detect and compensate for fluctuating leak sizes, resulting in more accurate delivered tidal volumes. The software adjusts the effective trigger sensitivity in the presence of leaks, helping to reduce the incidence of auto-triggering and manage the baby’s inspiratory work of breathing.

By effectively managing airleaks during both invasive and noninvasive ventilation, the Puritan Bennett™ 980 neonatal ventilator can help clinicians provide the right ventilation, supporting the effort to keep babies safe and comfortable.9

Connect with Medtronic Patient Monitoring & Respiratory Interventions
Your platform for clinical & product educational content. 


Medtronic announced that it has decided to keep the Patient Monitoring and Respiratory Intervention businesses as a part of Medtronic, given changing market conditions. These businesses will get increased investment and be combined and called Acute Care & Monitoring (ACM).

Medtronic also made the decision to exit the ventilator product line.

Amid evolving market conditions and a shift to lower acuity ventilators, this decision aligns with Medtronic’s strategy to concentrate resources on our market-leading positions and accelerate innovation-driven growth.

While this decision will take time and planning, we are committed to supporting our existing ventilation customers. We will continue to provide service and support throughout the ventilator life cycle, along with meeting our service contract obligations.
