MEDTRONIC LIFEPAK 20 Fact Sheet (Read info and take quiz)
The Medtronic Lifepak 20 is a semi-automatic defibrillator.
This model is a biphasic defibrillator which uses a biphasic truncated exponential waveform.
The energy protocol for this model is 200 joules for the first shock, 300 joules for the second shock and 360 joules thereafter.
Standard paddles can be used for Quick-Look ECG monitoring, defibrillation and synchronized cardioversion.
The hinged door hides the manual defib and noninvasive pacing buttons.
To enter the manual mode, press the MANUAL button located on the left lower corner of the door. This takes the device out of the AED mode to allow for manual defibrillation and pacing. After entering the manual mode, closing the door will not return the device to the AED mode, however, pushing the ANALYZE button while in the manual mode will return the device to AED operation.
Pressing the HOME button will return you to the main screen.
Using the speed dial will scroll through the menu items. The LED light will illuminate when in use.
A conductive medium such as gel or pre-gelled defib pads must be used between the standard paddle surface and the skin.
A significant shock hazard does exist if the operator discharges the defibrillator prior to clearing the patient.
Anterior-lateral position for defib pads: the positive electrode pad should be placed lateral to the left nipple with the center of the pad in the midaxillary line. The sternal pad is placed on the patient's upper right chest, lateral to the sternum with top edge underneath the clavicle.
Anterior-posterior position for defib pads: The positive electrode is placed over the left precordium with the edge of the electrode under the left nipple. (Do not place over the nipple, diaphragm or bony prominence of the sternum.) The negative electrode pad sandwiches the chest and is placed behind the heart in the infrascapular area. The anterior-posterior pad placement is an alternative position for noninvasive pacing, maunal defibrillation or synchronized cardioversion. It cannot be used for automatic defibrillation or ECG monitoring.
The pediatric defibrillator paddles are stored in the handset of the standard paddles.
To connect the therapy cable to the Lifepak 20, orient the cable so the arrow is on top with the cable angled to the right. Insert into the therapy cable connector until the connector "clicks".
The best lead to use when attempting a synchronized cardioversion is Lead II or the lead with the greatest QRS amplitude.
You must depress the "SYNCH" button each time a synchronized shock is desired. A sensing traingle marker will flag the R wave of the QRS complex.
When discharging the paddles in synch mode, you must press and HOLD the shock button until discharge occurs.
To use the pacing function, you must use the pacing pads as well as the three lead electrodes.
Pushing and holding the PAUSE button while in pacing mode will decrease the pacing rate to 25% of preset rate so that you can view the underlying rhythm. When you release the pause button, pacing rate returns to set rate.
The pacing current or rate can be changed two ways. Press the CURRENT or RATE button to increase by increments of 10. Press the CURRENT or RATE button, then rotate the speed dial by increments of 5.
The defibrillator charge will be maintained for 60 seconds at which time it will be disarmed if the shock button is not depressed.
To remove a charge from the defibrillator, push the ENERGY select button.
Do not use pacing/defib pads that have been out of the foil package for more than 24 hours. Do not remove pacing/defib pads from the skin and reapply. this can cause air pockets that can burn skin during defibrillation attempt. One set of pads should be effective for up to 50 shocks. Replace pads after 50 shocks, 24 hours on skin or after 8-12 hours of continuous pacing.
Wipe standard paddles after use with mild soap and water, using only a damp sponge and dry thoroughly.
To maximize battery life, plug the machine into AC outlet to recharge whenever the Lifepak is not in use.
