The M4735A HeartStart XL Defibrillator/Monitor is a lightweight, portable, semi-automatic external defibrillator. It offers two modes of operation for defibrillation:
- Automated External Defibrillation (AED) Mode
- Manual Mode
Both modes incorporate a low energy SMART Biphasic waveform for defibrillation.
In AED Mode, the M4735A HeartStart XL Defibrillator/Monitor analyzes the patient’s ECG and advises you whether or not to deliver a shock. Voice prompts guide you through the defibrillation process by providing instructions and patient information. Voice prompts are reinforced by messages that appear on the display.
In Manual Mode, the M4735A HeartStart XL Defibrillator/Monitor turns control of the defibrillation process over to you. You assess the patient’s ECG, and select the energy setting for defibrillation if necessary. Manual Mode also allows you to perform synchronized cardioversion and offers noninvasive pacing (optional).
Defibrillation is performed through external or internal paddles (both optional), or through multifunction defibelectrode pads. Monitoring is avail- able in AED and Manual Mode through pads, 3-lead ECG monitoring electrodes, or optional 5-lead ECG monitoring electrodes. Optional pulse oximetry (SpO2) monitoring is also available in AED and Manual Modes.
While monitoring ECG or SpO2, you may set heart rate and/or SpO2 alarms to alert you when these parameters are outside the defined limits.
The M4735A HeartStart XL Defibrillator/Monitor automatically stores critical events in its internal memory, such as shocks and alarm violations. Additional events of interest may also be marked for storage. These events can be printed as they occur or as part of an Event Summary. The M4735A Heart- Start XL Defibrillator/Monitor also allows you to store data and events on an optional HeartStart XL-compatible data card (see Chapter 11 for a listing) for downloading to HeartStart Event Review Data Management Systems.
The versatile M4735A HeartStart XL Defibrillator/Monitor is highly configurable to better meet the needs of diverse users. The messages and softkeys vary, depending on how the M4735A HeartStart XL Defibrillator/Monitor is configured. Be sure to familiarize yourself with your configuration before using the M4735A HeartStart XL Defibrillator/Monitor (see “Configuring the HeartStart XL” on page 10-7).
The M4735A HeartStart XL Defibrillator/Monitor is powered by AC power and a rechargeable sealed lead acid (SLA) battery which allows the defibrillator to charge to 200 joules in less than three seconds. Proper care of your batteries will ensure that they have the energy required to operate the M4735A HeartStart XL Defibrillator/Monitor and to deliver the appropriate therapy. (See “Battery Maintenance” on page 11-8.) Similarly, performing the specified operational checks will ensure that the M4735A HeartStart XL Defibrillator/Monitor is functioning properly and ready for use. (See “Operational Checks” on page 11-2.)
The M4735A HeartStart XL Defibrillator/Monitor is for use in the hospital by qualified medical personnel trained in the operation of the device and qualified by training in basic life support, advanced cardiac life support, or defibrillation. It must be used by or on the order of a physician.
When operating as a semi-automatic external defibrillator in AED Mode, the M4735A HeartStart XL Defibrillator/Monitor is suitable for use by medical personnel trained in basic life support that includes the use of an AED.
When operating as a defibrillator/monitor in Manual Mode, the M4735A HeartStart XL Defibrillator/Monitor is suitable for use by healthcare professionals trained in advanced cardiac life support.
Defibrillation therapy is the definitive method for termination of a variety of potentially fatal arrhythmias. The M4735A HeartStart XL Defibrillator/Monitor provides this therapy through the application of a brief biphasic pulse of electricity to the cardiac muscle. This electrical energy is transferred through attached internal paddles applied directly to the patient’s heart, or through attached paddles or disposable multifunction defib electrode pads applied to the patient’s bare chest.
Note: Successful resuscitation is dependent on many variables specific to the patient’s physiological state and the circumstances surrounding the patient event. Failure to have a successful patient outcome is not a reliable indicator of defibrillator/monitor performance. The presence or absence of a muscular response to the transfer of energy during electrical therapy is not a reliable indicator of energy delivery or device performance.
Indications for AED Therapy
An AED is to be used in the presence of a suspected cardiac arrest on patients of at least 8 years of age that are:
- Not breathing
Contraindications for AED Therapy
An AED is not to be used on patients that exhibit one or any combination of the following:
- Spontaneous breathing
- Palpable pulse
Precautions for AED Therapy
The AED algorithm is not designed to handle erratic spiking problems caused by a properly or improperly functioning pacemaker. In patients with cardiac pacemakers, the M4735A HeartStart XL Defibrillator/Monitor may have reduced sensitivity and not detect all shockable rhythms.
NOTE: The Philips HeartStart XL AED algorithm is not intended for children under 8 years of age. For children older than 8 years, the American Heart Association recommends that standard operating procedures for AEDs be followed.
