PeDIA is a medical-grade whistling balloon that delivers anesthesia gases to children ages 3+ without using a traditional mask. Children inhale and exhale through the balloon's whistle mouthpiece, which creates a pleasant sound and inflates/deflates with each breath, allowing them to "play themselves to sleep." The device addresses a longstanding problem where 40-60% of children experience significant anxiety during mask placement, which can lead to aggressive behavior, nightmares, and bedwetting lasting weeks to months. PeDIA is FDA cleared, fully patented (awarded 2018), and the world's first mask-free inhalation induction system for pediatric anesthesia.
