Using a Pulse Oximeter

Here's a step-by-step guide:

1. Prepare your finger: Sit upright. Wiggle your fingers and rub them together to get the blood flowing. This will ensure the most accurate reading.
2. Attach the device: Place the pulse oximeter clip onto one of your fingers. Make sure the tip of your finger touches the end of the device.
3. Position your hand: Keep the palm of your hand facing down.
4. Read the screen: Ensure the screen of the pulse oximeter is facing up so you can see the reading.
