Description
The AirOxy Fingertip Pulse Oximeter, model VM-2101, is a versatile device designed for non-invasive monitoring of arterial oxygen saturation (SpO₂) and pulse rate. Suitable for both adults and pediatric patients, it finds application in various settings, including hospitals, emergency care, sports medicine, and home care.
Display Features
Equipped with a vibrant OLED colour graphic display, the device provides clear readings with a resolution of 128 x 96 pixels. The display showcases essential metrics such as SpO₂ percentage, pulse rate, plethysmographic waveform, and a bar graph indicating pulse amplitude and signal quality. A battery status indicator ensures timely battery management.
Performance Specifications
- SpO₂ Measurement Range: 0–100%
- Pulse Rate Measurement Range: 20–300 bpm
- Accuracy:
- SpO₂: ±2% (70–100%)
- Pulse Rate: ±1 digit (≤100 bpm) or ±1% (>100 bpm)
User Controls and Operation
The VM-2101 operates efficiently on two AAA batteries, offering approximately 24 hours of continuous use. It features automatic power-off 15 seconds after finger removal to conserve battery life. User interaction is streamlined with a single button for display rotation, mode switching, and brightness adjustment across six levels.
Safety and Feedback
The device provides error messages for low battery and improper finger placement, along with warnings for environmental and patient factors that may affect measurement accuracy. It is not defibrillator-proof and should not be used during MRI scans. Proper finger placement is crucial for accurate readings, and it is not intended for sole use in clinical decision-making.
Physical Characteristics
- Dimensions: 57 x 33 x 27 mm
- Weight: Approximately 50 g (with batteries)
- Water Resistance: IPX2 rating
Maintenance
The oximeter requires no calibration and contains no user-serviceable parts. Cleaning is simple with a soft cloth and nonabrasive cleaner, or disinfection with a 10% chlorine bleach solution.
Compliance and Packaging
As a Class IIa medical device, the VM-2101 is CE marked and complies with relevant standards, including EN 60601-1-2 and BS EN ISO 9919:2005. The package includes the main unit, a lanyard, two AAA batteries, and a user manual on CD, providing comprehensive support for immediate use.
