Modernizing hand ventilation

Imagine you are walking down the hallway when someone collapses in front of you. First responders rush in and apply a bag valve mask also known as a manual resuscitator, ensuring life giving air makes it to the patient’s lungs. This simple device saves countless lives per year, but poor technique also causes severe problems that don’t show up until the first responders are long gone.

Bag Valve Masks

Bag valve masks, also known as manual resuscitators or “self-inflating bags,” are simple devices consisting of a flexible air chamber (about the size of a football) attached to a mask. When squeezed the device draws air from the environment or air cylinder into the bag, and when squeezed by a medical professional transfers air into the patient’s lungs. Squeezing too fast or too hard can damage the lungs, sometimes severely. 

The Problem

Bag valve masks are used tens of millions of times per year by first responders, battlefield medics, and hospital provides from all professional groups in the US and around the world. The incidents of damaged lungs run in the thousands, costing hundreds of millions of dollars in the chronic care that follows. Pneumico is modernizing hand ventilation using technology to monitor ventilation quality. It provides real-time, objective feedback and actionable cues to users. 

The Solution

Our compact electronic monitor can attach to any bag valve mask and ensure that the guidelines for specific parameters set by the American Heart Association (AHA) and European Resuscitation Council (ERC) are met, thus assuring that lifesaving intervention doesn’t end up creating lifelong problems. The patent pending Pneumico  device monitors ventilation quality (pressure and rate) allowing the responders to know they are in the safe zone. In addition, by giving timely, objective feedback to CPR trainees we  provide them with the skills to build their confidence and readiness to act.
