General Description

The 920M PLUS is a digital handheld pulse oximeter that displays numerical

values for blood oxygen saturation and pulse rate (Figure 2).

The 920M PLUS operates for approximately 100 hours continuously

between alkaline battery replacements, or for 45 hours with the Rechargeable

NiMH (Nickel Metal Hydride) Battery Pack (optional). The 920M PLUS

requires no routine calibration or maintenance other than replacement of

alkaline batteries or recharging the optional battery pack using the Model

920MPC Charger Stand. (Refer to the Model 920MPC Operator’s Manual.)

Figure 2. 920M PLUS displays, indicators, and switches.

Oxygen saturation and pulse rate values are displayed by light-emitting diode

(LED) digital displays. On each detected pulse, the pulse quality LED blinks.

Patient pulse quality signals are graded as good, marginal, or inadequate and

are indicated as such by the pulse quality indicator blinking green, yellow, or

red, respectively. 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.

The 920M PLUS features pulse oximeter sensors for a wide range of patient

monitoring. Each sensor is designed for a specific site application and specific

patient size and weight range. Refer to specific sensor instructional inserts for

more detailed information about sensor use.
