What the Pulse Oximeter Is For

The YM504 fingertip oximeter measures blood-oxygen saturation and pulse rate for adults and children aged six and above. It stores up to 20 readings and displays the last five on startup, giving home users a simple way to track daily trends without clinical equipment.

Installation and Common Issues

Open the battery cover, insert the two supplied AAA batteries, and clip the device onto a finger. A single press powers it on; holding the button for two seconds opens the settings menu. Readings can fail if the finger is cold, moving, or has nail polish, and the silicone cushion must seat fully to avoid ambient light leaks.

Practical Limits of the Finger Clip Design

The spring-loaded clip fits a range of adult and child fingers, but very small or very large digits may not achieve the snug seal needed for accurate SpO2 and perfusion-index data. The 30-second auto-save countdown means rapid consecutive checks overwrite each other, so the 20-slot memory suits periodic spot checks rather than continuous monitoring.
