The ZEPHYRx Breathe Easy app is very intuitive and easy to use with step-by-step instructions and motivational messages throughout your spirometry test. It connects to a personal spirometer via Bluetooth, captures test results and sends that data to a secure, web-based provider dashboard in real-time. Breathe Easy offers key features like spirometry task reminders, built-in video call enabling your provider to coach you through your test, and eight breathing exercise games. Patients face many roadblocks to accessing care: transportation, cost, distance to travel, taking time off from work, unnecessary exposure to pathogens, and quite simply – the inconvenience. With a remote spirometry cloud solution, you can perform spirometry at your convenience and in the comfort of your home. Visit www.zephyrx.com to learn more.
