Step 1 – Turn On The Recorder


Press the green power button on the left to turn the recorder on. The light next to the power button should illuminate.

Step 2 – Connect to the Sensors


Connect yourself to the three sensors as shown. 

1. Airflow Sensor and Nasal Cannula: This measures your breathing patterns directly through airflow and sound.

Place the cannula underneath your nose with the longer prongs facing down toward your mouth. Each cannula is single-patient use and can be fit to your measurement.

2. Respiratory Effort Sensor and Chest Belt: This measures how much effort you are making to breathe through your chest movement.

Place the belt around your upper chest with the two ends fastened in front. Adjust the size so that it’s snug, but comfortable. The belt can be worn over your clothing.

3. Pulse Oximetry Sensor: This measures your heart rate and blood oxygen levels from your fingertip.

Slide your finger into the sensor so that your fingertip just reaches the end of the sensor. Children receive a pediatric sensor that can be worn on either the finger or the big toe, whichever fits best.

Step 3- Press Record


Once all sensors are connected, press the red record button to begin recording. A green light next to the record button indicates that the device is recording.

Don’t worry about stopping the recording. It will turn off on its own after 6 hours.

When testing for multiple nights, simply repeat these steps. Test for the number of nights ordered by your doctor. If you are unsure of how many nights your doctor ordered, you can contact Snap support or your doctor. Usually, Snap Diagnostics recommends testing for 3 full nights of sleep, as breathing patterns can vary significantly from one night to the next.

After Recording


Once you have finished recording, return your test for analysis.

  • If you received the test kit from your doctor’s office, return it to them.

  • If the test kit was delivered to your home, follow the return instructions in your kit to have it picked up.
