Physio-Control Lifepak 20 Features

AED

The Physio-Control Lifepak 20 AED provides quick and effective use. The Lifepak 20 easily converts to manual mode and is compact and lightweight for easy carrying. This AED is easy to maintain and service and is versatile to use. This Lifepak comes with SpO2 and pacing as options.

Modes

Manual Mode provides a normal operating capability for ALS users. Manual mode allows energy selections up to 360J, offers synchronous cardioversion, and pacing. The ECG waveform is displayed on the 4.53-inch display.

AED Mode provides a normal operating capability for BLS users. All user features are available except manual defibrillation, synchronous cardioversion, pacing, and access to archived patient records. This mode provides shock energy defaults up to 360J. Users have the option to display ECG waveforms and/or visual AED prompts on the display.

Setup Mode allows the operator to configure the device settings.

Service Mode allows the operator to execute diagnostic tests and calibration, display device mode software and hardware versions, and display and print the diagnostic code log.

In-service Mode simulated waveforms are available for demonstration purposes. The waveforms consist of short segments of realist data, which are repeated to form a continuous waveform.

Archive Mode provides the operator the opportunity to access records of previous patients for review, transmission, printing, editing or deletion.

Auto Test Mode performs daily self-tests.

Physio-Control Lifepak 20 Specifications

Power

The device is an AC line operated device with an internal battery as back up.
AC Power: 90-132 VAC 50/60 Hz, 198-264 VAC 50/60 Hz
total power draw less than 75 Watts
Internal battery back up: NiMh, batteries charge while device operates from AC power
Operating time: a new fully charged internal backup battery will provide the following prior to shutdown: 120 minutes of monitoring, 135 minutes of monitoring without pulse oximeter, 90 360 joules discharges, and 70 minutes of monitoring plus pacing
Typical battery charge time: <2 hours when the device is powered off and AC power is applied
Low battery indication and message: when the device is unplugged from AC power, it switches to battery. When the battery gets low, the battery detection icon is indicated with low battery message in the status area, and warning tone occurs

Data Management

The device can easily print a CODE SUMMARY report, including an introduction to the patient information and critical event record. The summary report also includes event and vital signs log, and waveform associated with certain events.

Communications

The device can print archived patient records and has two data communications port, which supports a serial data cable.

Monitor

ECG: can be monitored through 3-wire or 5-wire ECG cables. Standard paddles or therapy electrodes are used for paddles lead monitoring
Lead selections: Leads I, II and III with a 3-wire ECG cable, leads I, II, III, AVR, AVL, and AVF, V acquired simultaneously with a 5-wire ECG cable.
ECG size: 4, 3, 2.5, 2, 1.5, 1, 0.5, 0.25 cm/mV
Heart rate display: 20-350 bpm digital display
Voice prompts: used for selected warnings and alarms, configured on/off
SpO2: saturation range: 1 to 100%
Saturation accuracy: (70-100%) (0-69% unspecified): Adults/ Pediatric: ±2 digits with no motion, ±3 digits with motion. Neonates: ±3 digits with or without motion
SpO2 update averaging rate: user selectable 4, 8, 12 or 16 seconds
SpO2 measurements: functional SpO2 values are displayed and stored
Pulse rate range: 25 to 240 pulses per minute
Pulse rate accuracy: ±3 digits without motion and ±5 digits with motion

Why defibrillation?

Sudden Cardiac Arrest (SCR)-Rapid irregular rhythm causing the heart to quiver
Cause: Ventricular Fibrillation (VF)
Can lead to death if emergency shock not delivered
Defibrillation – to counteract fibrillation

The device used to administer an electric current (shock) to the heart

Types of Defibrillators

Manual external
Manual Internal
Automated External (AED)
Semi-Automated External
Implantable Cardioverter-Defibrillator (ICD)
Manual External Defibrillator

Widely used in hospitals and clinics

Inbuilt EKG reader
Clinician Diagnoses the condition and accordingly administers the shock through paddles or pads
Manual Internal Defibrillator

Exclusively used in operation theatres

The charge delivered through internal paddles in direct contact with the heart
Automated External Defibrillator (AED)

Used by laypersons requiring little training

Built-in heart rhythm analyzer
Advice whether a shock is required
Semi-Automated External Defibrillators

Used by paramedics and emergency medical technicians

Automated capabilities of AED
With ECG display and a manual override option
Implantable Cardioverter Defibrillator

Implants similar to pacemakers

Constantly monitor heart rhythm
Automatically administers shock for arrhythmias
Types of the waveform – Shape of defibrillation current

Monophasic damped sine waveform – delivers energy in one direction

Relies on the adjustment of joule settings
Biphasic damped sine waveform – bi-directional current flow
Measures impedance of patient and delivers a precise dose of electricity
Uses significantly low energy levels
Decreases risk of burn in Myocardial damage

Final Thoughts

Have you ever used a Lifepak 20? Are you looking to purchase a Lifepak 20? Soma Technology, Inc. not only technically refurbishes these defibrillators but also cosmetically refurbishes them to make them function and look the way they did when they originally came from the manufacturer.
