USING YOUR PULSE OXIMETER

The Pulse Oximeter may be used while the user is seated, standing or
lying down. The user should not be walking or running during
measurements and should take care not to excessively move the arm

Keeping the sensors clean will help ensure
accurate readings. Before and after each
