Intended Use

Intended for adult patients with heart failure for noninvasive fluid monitoring, and for adult patients at risk of lymphedema by measuring extracellular fluid differences via L-Dex ratio.

Technology

Cloud-based software facilitating bioimpedance spectroscopy measurements via SOZO or SOZO Pro devices. Measures electrical impedance parameters across multiple frequencies (3kHz to 1000kHz) to estimate body composition and fluid status. Uses Bluetooth paired tablet application and transmits data to cloud database for analysis and display.

Performance

Verification and validation testing were performed for software updates including user interface alignment, Bluetooth connectivity improvements, and L-Dex assessment module update. Algorithm verification confirms safe and effective performance matching predicate device.
