Study Notes

Indications for Use

Rad-57 and accessories are designed for continuous, noninvasive monitoring of functional oxygen saturation (SpO2), pulse rate, and levels of carboxyhemoglobin and methemoglobin.
Applicable for adults, pediatric, and neonatal patients, functioning effectively during both motion and still conditions, as well as for patients with varying perfusion states.
Suitable for use in hospitals, mobile environments, and home settings.

General Description of Pulse Oximetry

Pulse oximetry measures arterial oxygen saturation non-invasively through a fingertip sensor in adults, and on the hand or foot for neonates.
The sensor connects to an instrument via a patient cable, which processes and displays data.
Key output includes:
- SpO2 displayed as a percentage.
- Pulse rate as beats per minute.

Rad-57 Front Panel Controls

Features buttons to toggle between functional parameters; users can switch from SpO2 to SpCO readings using the display button.
Prioritizes clear monitoring of carboxyhemoglobin and methemoglobin levels through intuitive display controls.

Signal and Alarm Systems

Low PI (Perfusion Index) and SIQ (Signal IQ) indicators provide visual cues for weak perfusion and signal quality.
Alarm silencing options allow temporary muting for 120 seconds, ensuring caregivers can manage alarms effectively during monitoring.

Regulatory and Safety Information

Device classified for Rx only, to be sold by or under physician's order in the USA.
Conforms to European Medical Device Directive 93/42/EEC.
