Pulse Oximeter: Measures the amount of oxygen in the blood

When a person overdoses, their breathing slows/stops and they do not have enough oxygen in their blood. Using a pulse oximeter can help tell IF and WHEN a person needs Narcan.

Reading the Pulse Ox (%SpO2)

Above 96% No Narcan! 89% - 95% Check for signs of an overdose Place person in the recovery position Stay with the person and continue to check their pulse ox

Below 89% Give Narcan Call 911 After Narcan is given place person in recovery position

Best practices:

  • A pulse ox is not 100% right, always check for other signs of an overdose! If individual stays unresponsive, call 911!

  • Use the middle or ring finger as they are least likely to be calloused Black or darker skin can cause higher read on the pulse ox. Nail polish can also impact how well the pulse ox works.
