Respironics Hand Held Pulse Oximeter

Authorized Retailer

Respironics Hand Held Pulse Oximeter is a small, easy-to-use hand-held device that delivers on-the-spot oximetry readings. It is perfect for home use. The 920M has the added capability of storing up to 18 hours of trend memory. This pulse oximeter is intended for spot check use and can be connected to an external printer. The 920 has visual alarms for tracking patient status. It typically will operate for 100 hours continuously between battery replacements. The 920 requires no routine calibration or maintenance.

  • Model 920 or 920M Hand Held Pulse Oximeter
  • Instruction and Service Manual for Models 920 and 920M
  • Six AA batteries Model
  • 936 Sensor (Adult Articulated Finger Clip)
Estimated Shipping Time: 4-8 Business Days

How does Respironics 920 Oxygen Saturation Meter works?

  • The 920 determines arterial oxyhemoglobin saturation (%SpO2) by measuring the absorption of red and infrared light passed through tissue.
  • Changes in absorption caused by pulsation of blood in the vascular bed are used to determine arterial saturation and pulse rate.
  • Oxygen saturation and pulse rate are displayed on light emitting diode (LED) digital displays. On each detected pulse, the perfusion LED flashes. Patient perfusion signals are graded as good, marginal or inadequate and are indicated as such by the LED flashing green, yellow, or red. This simple method gives the user a pulse-by-pulse visual indication of waveform signal quality without requiring the user to perform complex waveform analysis during critical patient care situations.
  • Sensor disconnects or malfunction is indicated by lack of good perfusion flashes and/or a dash to the left of the SpO2 value on the LED display. Ultimately, if adequate perfusion pulses are not received, the SpO2 and Pulse Rate numerical values will be replaced by dashes.
  • When the batteries are low, the digital displays will blink.

When to use Respironics 920 Portable Pulse Oximeter?

  • The 920 Hand Held Pulse Oximeter is intended to be used for monitoring oxygen saturation and pulse rate for adult, pediatric, and neonatal patients in hospital, ambulatory, home, and EMS environments.
  • The 920 may be used for spot checking and/or continuous monitoring when attended by a healthcare professional. The variety of individual sensors available must be checked frequently to ensure proper circulation and application

What to buy with Respironics 920 Oximeter

How to use Respironics 920 Handheld Oximeter?

The 920 Hand Held Pulse Oximeter is portable and is intended for attended patient monitoring by trained personnel. It displays numerical values for oxygen saturation and pulse rate. Because the 920 Pulse Oximeter has no patient alarms, the user must frequently observe the Sp02 and Pulse Rate displays.

Respironics Pulse Oximeter

  • Turning on the Pulse Oximeter
    • Turn on the 920 Hand Held Pulse Oximeter by depressing the "|" button on the front of the pulse oximeter. When the 920 is powered on, the SpO2 and displays will cycle through the following sequence before displaying valid data values:
      • "888 888"
      • time saved in memory in hours and minutes
      • software revision number
      • “- -“


Respironics Pulse Oximeter

  • Verifying Operation
    • Verify that the sensor is properly positioned. Ensure the system is sensing the adequate perfusion by observing that the indicator is blinking green, and the blinking is correlated to the pulse rate for 10 seconds. Should the perfusion light be red or yellow or flashing erractically, reposition the sensor or try a different sensor.
  • Cleaning the Pulse Oximeter
    • The 920 Pulse Oximeter may be cleaned with a mild detergent and a soft cloth or with an isoprophyl alcohol wipe. Allow enough time for the 920 to dry thoroughly before reusing.

  • Contraindications
    • Do not operate in an explosive atmosphere.
    • Do not operate the Respironics 920 in an MRI environment.
    • Do not use the 920 in a situation where alarms are required. The 920 and 920M models have no audible alarms.

    • The 920 is intended only as an adjunct in patient assessment. It must be used in conjunction with clinical signs and symptoms.
    • Use only Respironics-manufactured sensors. These sensors are manufactured to meet the calibration requirements for Respironics pulse oximeters. Use of other manufacturer's sensors may cause improper pulse oximeter performance.
    • Check application site frequently to determine circulation, positioning, and skin sensitivity of the patient. Each patient's sensitivity to Respironics sensors may vary depending on their medical status or the condition of their skin.
    • Use of Respironics double-backed adhesive strips or the Hydrogel tape strips should be discontinued if the patient exhibits allergic reactions to the adhesive material.
    • Do not stretch the adhesive tape while applying the sensors. This may cause inaccurate readings or skin blisters.
