WARNING: Do not clean the monitor or sensors while it is on and/or

connected to AC power.

WARNING: Ensure that the ECG lead wires are neatly secured in a

manner that will prevent them from encircling the patient’s
neck, creating a strangulation hazard.

WARNING: Perform the decontamination process with the unit powered

these cases, a longer time duration between measurements
should be considered to decrease the number of cuff
inflations over a period of time. In extreme cases, a thin
layer of soft roll or cotton padding may be applied to the
limb in order to cushion the skin when the cuff is inflated.
This measure may affect NIBP performance and should be
used with caution.

NIBP is set to the Continuous mode and the 1 minute
Interval. When the NIBP “Continuous” interval is chosen, the
Trio will continually take back to back blood pressure

with a cleaning solution.

CAUTION: Do not use sensors or cables that are damaged or have

deteriorated.

CAUTION: Replace the battery with one of the following part numbers:

0146-00-0043 (for a sealed lead acid battery),
0146-00-0069 (for a Lithium Ion battery).

CAUTION: Remove the battery if the Trio is not likely to be used for an

extended period of time.

CAUTION: Remove the battery prior to shipping the Trio.

CAUTION: To avoid permanent damage, do not expose metal

components (pins, sockets, snaps) to disinfectants, soaps or
chemicals.

CAUTION: The cuff must be properly applied to the patient's limb

before inflating. If it is inflated without being securely
wrapped, damage to the cuff can result.

2. Technical Alarms

Technical Alarms are failures or errors that require resolution or attention to continue patient
monitoring (also called System Error Messages).

3. Waveform Data/Menus

The waveform data/menus area is used to display parameter waveforms and system menus.

Waveform Data

Up to four (4) waveforms may be displayed. When all waveforms are selected in the
TRACE SETUP menu, the waveforms will be displayed, from top to bottom, as follows:
ECG, SpO

(Pleth), IBP (optional), Respiration (RESP). (Refer to Trace Setup for details.)

2

Up to four (4) waveforms may be displayed on this monitor.

• If the parameter waveforms only include ECG, SpO2 (PLETH), and Respiration (RESP),
and the ECG cascade is set to OFF, then only three (3) waveforms will be displayed. If
the ECG cascade is set to ON, then four (4) waveforms will be displayed. The first two
(2) will be ECG.

• For those monitors in which IBP is ordered as an option, and the cascade is set to OFF,
the display will show four (4) waveforms: ECG, SpO

(PLETH), IBP, and Respiration

2

(RESP). If the ECG cascade is set to ON, then the cascaded ECG will replace the

(PLETH) waveform.

SpO

2

ECG Lead, Gain and Filter are displayed in the upper left corner of the main display. The
IBP waveform label is displayed in the upper left corner of the IBP waveform window.

The waveforms are refreshed according to the rate designated by the user. (Refer to
specific parameter sections for details of sweep speed.)

Menus

When performing menu functions, a menu will be displayed, potentially obstructing the
view of select waveforms. Select NORMAL SCREEN in the menu (or on the Front Panel
Keypad) to exit all menus and return to the normal screen. If the user does not perform
any screen operation for 30 seconds, the menu will be removed automatically and the
screen will return to the normal display mode. Trend displays do not time out.

5. Status Bar

The status bar is located at the bottom of the screen. It displays the DEMO MODE status, the
battery icons and the MENU icon.

• The DEMO MODE status message indicates that the monitor is in demo mode and is
displaying simulated patient data.

• The battery icons indicate the relative charge status of the optional battery.

• Battery (Full)

The battery full icon appears in the lower right portion of the display when the unit is
operated by battery power. When the batteries are fully charged, the color will be
filled in as shown.

• Battery (Low)

The battery low icon appears in the lower right portion of the display when the unit is
operating on battery power. When the batteries are running low, color appears only
on the right portion of the indicator.

• No Battery in Unit

The no battery icon appears in the lower right portion of the display when a battery is
not installed in the monitor.

•The MENU icon is used to access the SYSTEM MENU. It is a rectangular icon
positioned below the parameter tiles and is the same width as that area.

Operations

2.1 Getting Started

The Trio features default factory settings that enable monitoring to begin without setting
waveforms, parameters, alarms, or functions. Each of these settings can be changed based
on specific patient or departmental needs. Certain operating characteristics (e.g. NIBP start
pressure) are based on the selected patient size.

CAUTION: The patient size selection should be matched to the actual

patient before monitoring begins.

Before using the monitor, complete the following steps:

1. Examine the device, all external cables, inserted modules and accessories for damage

2. Check all monitor functions for proper operation.

NOTE: If the monitor is damaged, contact the biomedical engineer

of the hospital or Customer Service immediately.

2.1.1 Setting-up Patients

1. Turn the monitor ON using the POWER key on the front panel.

2. Remove all of the previous patient data (except BED # and SIZE) as follows:

a. Use the Navigator™ Knob to select the MENU icon located in the bottom right

corner of the screen. The SYSTEM MENU (FIGURE 2-1) is displayed.

b. From the SYSTEM MENU, select PATIENT SETUP. The PATIENT SETUP menu

(FIGURE 2-2) is displayed.

c. Select PATIENT DISCHARGE. A confirmation dialog is displayed with the prompt,

Discharge patient from monitor?.

d. Select YES to remove the previous patient data from the monitor.

3. Connect the patient to the monitor, apply appropriate accessories such as ECG

electrodes, NIBP cuff, SpO

probe, etc.
