CMI Health SpiroLink B1 Smart Peak Flow Meter
The CMI Health SpiroLink B1 is an FDA-cleared smart spirometer that measures peak expiratory flow (PEF) and forced expiratory volume in one second (FEV1) with clinical precision. Unlike turbine-based devices, the SpiroLink B1 uses a pressure sensor that resists debris, mucus, and moisture — extending device lifespan and maintaining measurement accuracy. Rechargeable and Bluetooth-enabled, it pairs with a mobile app for effortless data tracking and sharing.
- FDA-cleared for PEF and FEV1 measurement
- Pressure sensor design resists debris and moisture for longer device life
- Rechargeable battery with USB charging
- Bluetooth connectivity with companion mobile app
- Includes 2 removable mouthpieces for hygienic use
Clinical-Grade Lung Testing:
The SpiroLink B1’s pressure sensor technology is a significant step up from traditional turbine spirometers. Turbine devices can be thrown off by saliva or debris, while the pressure-based design maintains accuracy even under typical in-home use conditions — making it ideal for patients who need reliable, repeatable pulmonary results.
