Pulse Rate (PR) Cont'd

F4 and the UP/DOWN Arrows allow the user to dial any value they want from 15-330

BPM.

Pressing F4 changes the size of the steps the arrow keys will increment/decrement by

(1, 5, 10, or 50)

To leave press MENU again, or simply begin another reading on the monitor. With the

generic keypad the ESCAPE key is a third way to exit this menu.

Meter Mode

Press the Meter button (NIBP keypad) or for (Generic Keypad) use the Escape button to

return to the menu and select Meter Mode.

Here the AccuPulse acts as a pressure meter (manometer) with 0.1mmHg resolution. In

addition to the current value, min, max and a moving average are also simultaneously

displayed.

The user has the option to use the internal pump to inflate the system to various

pressures.

Using the Cal button increases the pressure in 50mmHg steps providing an easy way to

do a multi-point calibration check.

Using SetP allows the user to select any value for an inflation point from 50-400 mmHg

and adjust it up and down in steps as small as 1 mmHg by using the UP/DOWN arrow

keys.

Leak Test Mode

Press the Leak Test button (NIBP keypad), or for the (Generic Keypad) use the Escape

button, to return to the menu and select Leak Test.

The default is an automated test. When Start is pressed the AccuPulse Plus pump will

inflate to a preset pressure, settle at that point, then begin counting down the preset

time. At the end of this the difference between the start and end pressure is displayed.

Over-P Mode

Press the OverP Test button (NIBP keypad), or for (Generic Keypad) use the Escape

button, to return to the menu and select OverP Test.

When Start is pressed the AccuPulse Plus pump will inflate and the AccuPulse Plus

graphs the pressure. When the overpressure valve releases, the AccuPulse reports the

maximum pressure achieved.

Section 5. Detailed Operation

1) BP Test Mode

The Simulation Engine operates in this mode, delivering pressure pulses to the cuff. The

servo action begins when pressure in the system is > 10mmHg. If the user leaves the

menu tabs displayed, the servo will still start up if the system pressure becomes >

10mmHg. When it starts, the software will change the screen to display the test being

performed.

The figure below shows a typical BP Test Mode Screen with a maximum pressure scale

of 200mmHg (left edge of screen).

The pressure is at 0 mmHg ( upper right corner of screen ).

Approximately 27 seconds of pressure data is displayed on screen at one time ( bottom

scale is seconds ).

The top line of text indicates the current test settings in the format:

A(dult) patient, 120/80(93) SYS/DIA(MAP) pressure, 80 Beats Per Minute pulse, and

100% nominal amplitude.

At the bottom is an indication of the envelope set being used. The default Generic Presets

are used in this example.

Three parameters may be adjusted directly in this mode:

• The Up/Down arrow buttons cause the pressure scale to shift between 100, 200 and

300 mmHg max.

• The Left/Right arrow buttons cause the pressure data to be scrolled 10 seconds at a

time from 0 seconds to 120 seconds if the test time exceeds one screen of time. The

Left/Right arrow buttons are only available for test review, they do not scroll while the

test is active.

• Motion Artifact: This is a purchased option upgrade. Toggle motion artifact

off and on by pressing F1.

(The Motion Artifact option is covered in detail later in the manual)

The base AccuPulse Plus has supporting adjustment tabs accessible from this mode.

The support tabs are accessed by pressing the <Menu> button. These tabs

allow the user to make adjustments for this mode, selecting Adult or Neonatal patient

types, different Systolic / Diastolic presets, and Pulse Rate. Support tabs also provide the

more advanced ability to tune the presets if needed by shifting them up or down,

adjusting the overall amplitude of the pulses, and within the default generic envelope

adjusting the output for a better match to your monitor.
