Project Summary

Full Project Summary

A Portable Emergency Ventilator (PEV) is a device that can provide positive pressure ventilation to a person who is incapable of breathing on their own. Reasons for this lack of ability to breath include cardiac arrest, heart attack, smoke inhalation, and many others. This device can eliminate the need for mouth-to-mouth resuscitation used by first responders during CPR, thus drastically eliminating the spread of diseases. The device can also be used when transporting patients or in home use when a large ventilator is too expensive and impractical.

Many PEVs already exist and are being used by EMTs and physicians today. This project focuses on improving a PEV developed in the early 1990s by Jeff Gutterman and Roman Press. The device is patented and has been approved by the FDA to market and manufacture. The PEV device includes different modes which can be used based on different situations. These modes are Constant Mandatory Ventilation (CMV), Assist, CPR, and Manual. The mode which would be most useful to first responders is CPR. In this mode, the rescuer would perform CPR on the patient just as they normally would, using only chest compressions. The PEV would keep track of the number of compressions through a feedback network, and, based on a setting applied by the rescuer, provide clean air to the patient after a specific number of compressions were performed.

The current device has many characteristics which we plan to keep in the updated model. First, since the device has already been approved by the FDA, the general operation cannot deviate from the current design. Second, the PEV is durable so it can be dropped or used in inclement weather and yet still provide it’s life saving function. Third, the device has redundancies so that if a malfunction occurs, the patient can still be ventilated by other means. Finally, the device is easy to use with paramedics. The large knobs and audible feedback allows the PEV to be used by those wearing gloves and ensures incorrect use is not possible.

The goal of this project is to update the model using technology available today by making it lighter, more efficient, and easier to use. To make it is portable as possible, we plan on make this device less than 8 kilograms. Also, this device will run on a battery, which should have the ability to operate the device for at least 2 hours without requiring a recharge. This should provide sufficient time for the patient to be transported to a larger machine not running on battery power. Lastly, one very important aspect of this device is that it will be able to record the patient’s vitals as resuscitation is occurring. This will benefit the rescuer from this feature since he/she will no longer have to worry about writing down this information, along with the time it was taken. We expect to market our device once a final product is built and extensively tested.

This project will be completed by May 2013 with a budget of $1000. The ultimate goal is to have a working prototype. We will be guided by our customers, Jeff Gutterman and Roman Press, and our faculty mentor, Edward Hanzlik.
