FDA has cleared a Masimo 510(k) for the Radius PPG, a tetherless sensor associated with the Masimo SET patient monitor. The sensor eliminates the need for a cabled connection to a pulse oximetry monitor, allowing patients to move freely while still being continuously monitored. Through a wireless connection, measurements are displayed on Masimo host devices or third-party multi-parameter monitors with integrated Masimo technology, the company says. The device can also easily pair with multiple devices and it works with its integrated battery for about four days and stores up to four days of patient data.
