Start-Up and Use

Monitoring Mode

In Monitoring Mode - Pleth View (Figure 5), the NPB-295

displays SpO

2 readings, pulse rate readings, and a pleth

waveform. In the Monitoring Mode - Magnified (blip) View

(Figure 6), the Pulse Amplitude Indicator and a larger %SpO

2 and

pulse rate reading are displayed. The pleth waveform is not

displayed. How to select one of the two views by using the

softkeys will be discussed later in this section.

%SpO

2 is displayed for values between 0% and 100%. Pulse

rates are displayed for values from 20 to 250 beats per minute and

zero beats per minute. Pulse rates below 20 (except zero) will be

displayed as 20, and pulse rates above 250 will be displayed as

250. A pulse rate of zero is used to indicate that the monitor is

not monitoring a pulse.

A variable-pitch beep sounds once for each pulse, and the Pulse

Amplitude Indicator (in the Magnified View) visually displays

relative pulse strength at the sensor site. The pitch of the beep

decreases as %SpO

2 decreases.

Note: Verify that indicators, display information, and audible

sounds including alarms are operational, indicating that

the monitor is functioning. Each valid button push

should generate an appropriate audible or visual action.

Observe movement of the Pulse Amplitude Indicator or

pleth waveform, and listen for pulse beeps to verify that

measurements are being made.

If any action does not seem appropriate, do not use the

monitor. Instead, contact Mallinckrodt’s Technical

Services Department or your local Mallinckrodt

representative.

In Monitoring Mode, if the acquired pulse is lost, the monitor

enters Pulse Search Mode.
