InSpiro

Every day as clinicians perform their morning rounds, patients are asked whether they have been using their incentive spirometer, an inexpensive bedside device that promotes deep breathing with a visual feedback mechanism. Current clinical protocol suggests performing deep breathing exercises using the incentive spirometers ten times per hour as a preventative measure to reduce postoperative pulmonary complications that include atelectasis, pneumonia, and bronchitis. As a testimony to their efficacy, incentive spirometers are provided to every single patient who undergoes general anesthesia. Unfortunately, it’s impossible to tell if a patient has actually been using the spirometer, forcing clinicians to rely on patient memory, which is neither objective nor accurate in the post-operative period.

This E-Team is designing an electronic, disposable incentive spirometer that will quantify when a patient uses it. The device is designed to allow hospital staff to monitor patient usage and lung capacity performance—features not possible with current embodiments. Ultimately, the team hopes to expand into the full spirometry market to help diagnose non-hospitalized patients for conditions such as pneumonia.
