Risks and Benefits
Before using any medical device, it is important to consult your physician and weigh the risks
and benefits.
The following section describes the Benefits and Risks associated with using MightySat Rx.
Risks of MightySat Rx
•As with all medical electrical devices, there is always a risk of electrical,
mechanical, and fire hazards. However, these risks have been mitigated through
the design and testing of MightySat Rx.
•As with all devices with small parts, there is always a risk of a child’s swallowing a
component or choking. Keep small parts away from small children to prevent such
hazards.
•As with all items applied directly to the skin, there is always a risk of skin irritation,
pressure injury, and general discomfort while a sensor or cuff is applied to a
patient. Periodically check the areas where the patient’s skin makes contact with
the sensor or blood pressure cuff to prevent potential issues.
Benefits of MightySat Rx
•MightySat Rx is a portable fingertip device able to provide pulse oximetry
measurements including oxygen saturation (SpO2), pulse rate (PR), perfusion
index (Pi), Respiratory Rate (RRp), and pleth variability index (PVi) within a home
environment.
•The MightySat Rx with optional Bluetooth can wirelessly transfer data to a
compatible smart device for a larger display and/or storage of data.
