Key Features
Design
This non-invasive, handheld patient monitor has three parameters: arterial oxygen saturation (SpO2), pulse rate (PR), pulse strength. The monitor measures parameters through a SpO2 sensor and displays them on the LED screen after processing them. Both an audio and a visual alarm sound and parameter measurements flash on the screen when normal parameters are exceeded or the sensor is removed. Customers can choose yellow or blue as the device colour.
Usability
This device is easy to use. It requires common 1.5V AA alkaline or rechargeable batteries.
Display/Controls
The monitor is operated and controlled by the buttons on the front panel. A LED screen displays measurements and supplementary status indicators. The screen shows a battery capacity indicator which has an automatic power-saving shutdown feature when no monitoring is detected for 3 minutes.
