    you demandOptimized for a variety of uses and environments AED, crash cartdefibrillator, critical care transport monitor and cardiograph itsremarkably easy to operate:

    Thoughtfully organized controls and

    ports clearly separate functions,

    monitoring from therapeutic.

    Monitoring starts once a patient cable is

    connected to the device.

    Monitoring and therapy data are clearly

    and logically arranged on-screen.

    Large numeric measurements,

    waveforms, and alarm indicators enable

    the user to quickly locate information.

    The appearance of measurements

    and waveforms can be customized,

    and the screen organized to the

    users preferences.

    On-screen menus simplify navigation

    for configuring data, setting and

    responding to alarms, and accessing

    additional functionality.

  • Superior Diagnostic Measurements

    A typical monitoring view shows somebasic patient information, the date,time and battery status. Next are thenumerics and waveforms.The bottomhalf of the screen shows additional monitoring parameters, SpO2 and CO2numerics followed by their waveforms,and soft keys for customizing the display,setting and responding to alarms, andselecting parameters to view additionalmonitoring data.

    HeartStar t MRx features many of thesame measurement algorithms andalarms found in our industry-leadingpatient monitors and cardiographs.The ECG cables, NBP cuffs, SpO2sensors, and CO2 filter lines used onHeartStar t MRx are interchangeablewith those other devices.

    Arrhythmia MonitoringHeartStar t MRx employs Philips' ST/ARBasic arrhythmia algorithm to analyzeECGs for hear t rate, while continuouslymonitoring for ventricular arrhythmiasand generating visible and audiblealarms as needed. ST/AR detects 10 rhythm disturbances, including 5 life-threatening arrhythmias: asystole,ventricular fibrillation, ventriculartachycardia, extreme bradycardia, andextreme tachycardia.

    SpO2 with Fourier ArtifactSuppression Technology (FAST-SpO2)With its low-noise hardware andpatented digital processing, FAST-SpO2produces few false readings, drop-outsand false alarms in the presence ofmotion and other interferences.Thealgorithm uses numerous technical andphysiological criteria, as well as qualityindicators, and applies rule-based analysisand scoring to generate the Fourierspectrum.The FAST-SpO2 algorithmeven measures reliably in the presenceof low peripheral perfusion.

    Noninvasive Blood Pressure (NBP)HeartStar t MRx is equipped with theADVANTAGE oscillometricnoninvasive blood pressure system fromSunTech Medical Instruments.Developed for transport applications,this motion-tolerant system accuratelyand reliably measures systolic anddiastolic pressure and calculates meanar terial pressure in any environment.

    Microstream Capnography (etCO2)With Microstream CO2 measuringtechnology from Oridion Medical, thereis no zeroing, no heating and no sensorto interfere with the patients airway.And the Microstream system monitorsetCO2 on both intubated andnonintubated patients.On nonintubatedpatients,respiration samples are collectedthrough a nasal cannula. MicrostreamsFilterLine airway adapter and sampleline inhibit the build-up of condensedwater and secretions from the patient(i.e., no water trap), allowing theinstrument to collect CO2 samples inany orientation without clogging.

    Philips 12-Lead ECGThe 12-lead algorithm in HeartStar tMRx, which is also used in PhilipsPageWriter Touch cardiograph andIntelliVue bedside monitors, delivers

    both ECG data and interpretation.And, for patients with symptoms of ST-segment elevation acute myocardialinfarction (STEMI), the algorithm detectsand stratifies early acute coronarysyndromes.

    Philips 12-Lead Algorithm features asophisticated pacemaker pulse detectorand paced rhythm classifier. The algorithmis designed to understand a variety ofatrial, ventricular, and A-V sequentialpacing modes and to recognizeasynchronous pacing typically seen with a magnet in place. In addition toautomated detection capabilities, thealgorithm provides user-selectedconfiguration of pacemaker patientor non-pacemaker patient for more accurate analysis.

    With patients under the age of 16,the algorithm employs its PediatricCriteria Program, which recognizes 12 distinct age groups to ensure that the most age-relevantinterpretation criteria are applied for analyzing ECG data.

    Q-CPR Measurement andFeedbackHeartStar t MRx, with the power of Q-CPR by Laerdal, monitorsand analyzes CPR performance compression rate and depth,ventilation volume and frequency providingmeasurements and indicators on-screen and audio feedback when needed. Q-CPR reinforces CPR training with each and every use.

    In code view, a single ECG wave is shownin the top half of the display, the incidenttimer is prominent and all alarms arepaused. CPR numerics and thecompression wave appear in the middle.The bottom of the display accomodatesthe CO2 wave and active soft keys.4

  • Clinically Proven Therapies

    Pediatric and adult paddle electrodes with Philips patented Patient Contact Indicator (PCI).


    A flashing hourglass in the ready-for-useindicator window signals that HeartStart MRx hasample battery power to monitor and deliver ashock. If battery power is low, ECG capability iscompromised, or MRx detects that it cannot paceor shock, a red X replaces the hourglass and thedevice audibly chirps until the situation is corrected.

    Defibrillation therapies are activated, using thetherapy knob on the front right side of MRx.

    SMART Biphasic TechnologyPhilips patented low-energy SMARTBiphasic (truncated exponential)waveform is proven effective inemergency resuscitation and forminimizing post-defibrillation hear tdysfunction. Its impedance compensationalgorithm measures chest impedanceand delivers a low-energy shock basedon the patients unique physicalrequirements.

    No other external defibrillationwaveform is supported by more peer-reviewed clinical data.

    AED Mode AED mode enables the first caregiveron-scene to deliver a lifesaving shockwithin seconds of arrival. Clear, concisevoice and text prompts guide the userthrough the process.

    Manual DefibrillationWhen switching to manual mode, theuser selects defibrillation energy (1)with the therapy knob.With the press

    of a button (2), MRx charges. Hear tStar tMRx charges to its highest energy level,200 Joules, in less than 5 seconds.Then,pressing the shock button (3), MRxdelivers defibrillation therapy.

    HeartStar t MRx defibrillates with eitherpaddles or pads. If paddles are preferred,MRx can be equipped with a set ofexternal paddles.These anterior/anterior paddles (water resistant available)are for adult and pediatric use andconvert from adult to pediatric byremoving the outer contacts. Sensors inthe external paddles electrodes assesspaddle-to-patient contact and displaytheir readings in the Patient ContactIndicator (PCI) located on the sternumpaddles handle.

    For open-hear t and other intrathoracicprocedures, HeartStar t MRx can be usedwith our line of internal defibrillationpaddles, which come in a range of sizes.

    HeartStart Defibrillator PadsOptimized for Philips defibrillators,Hear tStar t Multifunction DefibrillatorPads come in adult, pediatric, andspecialty choices to fit the needs of avariety of depar tments, caregivers,patients and treatments fromemergency use to ECG monitoring and radiological procedures.Whenconnected to MRx, they can provideECG monitoring, synchronizedcardioversion, and noninvasive pacing,in addition to external defibrillation.

    Synchronized CardioversionPhilips SMART Biphasic waveform hasundergone clinical testing, and peer-reviewed evidence supports itseffectiveness in cardiover ting atrialfibrillation. Synchronized cardioversion

    is activated by selecting an energysetting, then pressing the sync key justabove the therapy knob. In sync mode,R-wave markers are shown on-screenabove (or on) each detected R-wave.

    Noninvasive PacingHeartStart MRx paces with a monophasictruncated exponential waveform.Thepacers 40 msec pulse width is constant,while rate and output (mA) areadjustable. MRx offers both us
