1: Introduction Features and Capabilities
Features and Capabilities
The HeartStart MRx is a lightweight, portable, monitor/defibrillator. It provides four modes of
operation: Monitor, Manual Defib, AED, and Pacer (optional).
In Monitor Mode you can monitor up to four ECG waveforms, acquired through a 3-, 5-, or 10-lead
ECG set or multifunction electrode pads. Optional monitoring of pulse oximetry (SpO
pressure (IP), non-invasive blood pressure (NBP), temperature (Temp), and carbon dioxide (EtCO
also available. Measurements from these parameters are presented on the display and alarms are available
to alert you to changes in the patient’s condition.
Monitor Mode also provides an optional 12-Lead ECG function, enabling you to preview, acquire, store,
transmit, and print 12-Lead ECG reports, with or without analysis/interpretation.
Manual Defib Mode offers simple, 3-step defibrillation. You analyze the patient’s ECG and, if
appropriate: 1) select an energy setting, 2) charge, and 3) deliver the shock. Defibrillation may be
performed using paddles or multifunction electrode pads. Manual Defib Mode also allows you to
perform synchronized cardioversion and internal defibrillation.
In AED Mode, the HeartStart MRx analyzes the patient’s ECG and determines whether a shock is
advised. Voice prompts guide you through the 3-step defibrillation process, providing easy-to-follow
instructions and patient information. Voice prompts are reinforced by messages that appear on the
display.

Both Manual Defib and AED Mode incorporate the Philips’ low energy SMART Biphasic waveform for
defibrillation, Q-CPR, and audio recording.
Optional Pacer Mode offers non-invasive transcutaneous pacing therapy. Pace pulses are delivered
through multifunction electrode pads, using a monophasic waveform.
The HeartStart MRx is powered by rechargeable lithium ion batteries. Available battery power is easily
determined by viewing the convenient battery power indicators located on the device display or by
checking the indicators on the battery itself. Additionally, an external AC or DC power supply may be
applied as a secondary power source and for continual battery charging.
The HeartStart MRx performs Automated Tests on a regular basis. The status of the device’s critical
functions are reported to the Ready For Use (RFU) indicator. Prominently displayed, the RFU indicator
communicates the status of your device, letting you know if it is operating correctly, needs attention, or is
unable to deliver therapy. In addition, performing the specified Operational Check ensures that the
HeartStart MRx is functioning properly.
The HeartStart MRx M3535 model with the IntelliVue Networking Option can connect to the Philips
IntelliVue Clinical Network.
The HeartStart MRx automatically stores critical event and trend data in its internal memory, such as
Event Summaries and 12-Lead Reports. The HeartStart MRx also enables you to copy data and event
information to an optional external data card for downloading to Philips’ data management solution,
HeartStart Event Review Pro, as well as transfer data using Bluetooth
transferred using Rosetta-Lt™.
The HeartStart MRx is highly configurable to better meet the needs of diverse users. Be sure to
familiarize yourself with the device’s configuration before using the HeartStart MRx.

NBP Safety Features
The NBP module is equipped with the Timeout and Overpressure safety features that prevent injury to
the patient and damage to the device.
NBP Timeout
The NBP module times out when the pressure remains greater than 10 mmHg for 3 minutes. Do not
keep the cuff pressurized for more than 3 minutes during the calibration.
NBP Overpressure
The NBP module overpressure occurs when the cuff pressure reaches 300 mmHg. Do not raise the
pressure in the cuff to more than 280 mmHg during the calibration.
The safety features cause the valve to open and the pressure to drop.
To reset the module if a safety feature is triggered during calibration:

set up as they were at the end of the previous test.
If all results are as described, the device passes that portion of the test. Return to the Service Mode Main
menu by pressing the
If there is any failure, begin troubleshooting and repairing the device as needed. See “Troubleshooting”

Accuracy Test
To test the NBP Module accuracy:
1 Connect the NBP tubing to the NBP port on the monitor/defibrillator, and connect the test
manometer and cuff to the tubing. See Figure 10 “NBP Calibration Setup” on page 15.
2 Pressurize the cuff to approximately 250 mmHg.
3 Wait for 30 seconds to allow the pressure in the unit to equalize.
4 When the pressure stabilizes, compare the displayed pressure reading to the pressure indicated by the
manometer.
Main Service softkey.
5 If the difference between the manometer and the displayed pressure is more than 2 mmHg, calibrate
the NBP module as described in “NBP Module Calibration” on page 14 and repeat the test.
6 Release the pressure in the cuff before proceeding to the next test to avoid the safety timeout.
Leakage Test
To test the NBP Module for leaks:
1 Pressurize the cuff to approximately 250 mmHg.
2 Wait for 30 seconds to allow the pressure in the unit to equalize.
3 Watch the displayed pressure for 60 seconds.
4 Record the pressure drop at the end of 60 seconds.
5 If the pressure decreases by more than 6 mmHg, there is a leak. Replace the tubing and cuff assembly
and try the leakage test again. If the pressure still decreases by more than 6 mmHg, begin
troubleshooting and repairing the device as needed.
6 Release the pressure in the cuff before proceeding to the next test to avoid the safety timeout.
Linearity Test
To test the NBP Module linearity:
1 Pressurize the expansion chamber to approximately 150 mmHg.
2 When the pressure is stabilized, compare the displayed pressure reading to the pressure indicated by
the manometer.
3 If the difference between the manometer and the displayed pressure is more than 2 mmHg, calibrate
the NBP module as described in “NBP Module Calibration” on page 14 and repeat the test.

2: Maintenance EtCO2 Module Calibration
EtCO2 Module Calibration
This section describes how to calibrate the HeartStart MRx EtCO2 (sometimes called CO2) module.
EtCO2 Calibration Equipment
To calibrate the HeartStart MRx EtCO2 module you need:
•Gas flow valve
• Modified Filterline set with T-shaped tubing assembly
• 5% calibration gas cylinder (15210-64010, six cans per case)
•Calculator
• Barometer to measure ambient pressure or other means of determining the ambient pressure.
Both the gas flow valve and Modified Filterline are provided in the CO
# 453564063851. The CO
troubleshooting only (see “EtCO
Calibration Kit, also contains a flow tube and two air plugs that are used for
2
Module Checks” on page 23) and not used in calibration.
