Indications for use parsed from FDA documents
? Radius VSM: The Radius VSM and accessories are intended to be used as both a wearable multi-parameter patient monitor and an accessory to a multi-parameter patient monitor that is intended for multi-parameter physiological patient monitoring in hospital and healthcare facilities. The Radius VSM and accessories are indicated for the monitoring of hemodynamic (including ECG, arrhythmia detection, non-invasive blood pressure, Sp02, Pulse Rate, PVi, heart rate, and temperature), and respiratory (e.g., impedance, acoustic, and pleth-based respiration rate) physiological parameters along with the orientation and activity of adults. The Radius VSM and accessories are indicated for the non-invasive continuous monitoring of functional oxygen saturation of arterial hemoglobin (Sp02) and Pulse Rate (PR) of well or poorly perfused adults during both no motion and motion conditions. The Radius VSM and accessories are indicated for continuous monitoring of skin temperature of adults. The Radius VSM and accessories are indicated for monitoring of the orientation and activity of patients including those susceptible to pressure ulcers. The Radius VSM and accessories are indicated for the continuous non-invasive monitoring of PVi as a measure of relative variability of the photoplethysmograph (pleth) of adults during no motion conditions. PVi may be used as a noninvasive dynamic indicator of fluid responsiveness in select populations of mechanically ventilated adult patients. Accuracy of PVi in predicting fluid responsiveness is variable and influenced by numerous patient, procedure and device related factors. PVi measures the variation in the plethysmography amplitude but does not provide measurements of stroke volume or cardiac output. Fluid management decisions should be based on a

ChatPPG interpretation
A 510(k) decision of "substantially equivalent" means FDA found the device as safe and effective as a legally marketed predicate. FDA's word for this is cleared, not approved. The clearance covers the device and indications in this submission; it does not extend to other features or versions of the same product that were not part of it. See FDA cleared vs approved.
Product code MHX is "Monitor, Physiological, Patient(With Arrhythmia Detection Or Alarms)", class 2, 21 CFR 870.1025.
