USING THE HEARTSTART ONSITE

IMPORTANT NOTE: Be sure to read the WARNINGS and CAUTIONS throughout this manual as well as in Section 1.

WARNING: Do not use or stack the OnSite unit with other equipment. If the unit is used or stacked with other equipment, verify proper operation prior to use.

OVERVIEW ABOUT Philips HeartStart OnSite Defibrillator M5066A 
If you think someone is in SCA, act quickly and calmly.

• If the patient is an infant or child, first perform CPR, then call for emergency medical services (EMS) before you apply the OnSite. See the special section on treating infants and children.
• Call your emergency services provider. If someone else is available, ask him or her to call for emergency medical assistance while you get the OnSite.
• Quickly get the OnSite and bring it to the victim’s side. If there is any delay in getting the defibrillator, check the patient and perform cardiopulmonary resuscitation (CPR) if needed until the OnSite is available.
• It is safe to use the HeartStart OnSite Defibrillator on a patient lying on a wet surface. Before doing so, remove the patient from standing water, such as a pool or bathtub. It is also safe to use the HeartStart OnSite Defibrillator on a patient lying on a conductive surface, such as a metal surface. It is important to dry the patient’s chest completely, so that the pads stick well to the dry, bare skin.
• Check the immediate environment for flammable gases. Do not use the OnSite in the presence of flammable gases, such as an oxygen tent. However, it is safe to use the OnSite on someone wearing an oxygen mask.

There are three basic steps to using the OnSite to treat someone who may be in sudden cardiac arrest:

1. PULL up the handle on the SMART Pads Cartridge.
2. PLACE the pads on the patient’s bare skin.
3. PRESS the flashing Shock button if instructed.

The following pages provide details about each step.

STEP 1: PULL THE GREEN HANDLE

• Turn on the OnSite by pulling the SMART Pads Cartridge’s green handle.*

  

• Remove the hard cover from the pads cartridge and set it aside. Remain calm and follow the OnSite’s instructions.

• The OnSite starts by directing you to remove all clothes from the patient’s chest. If necessary, rip or cut off the clothing to bare the person’s chest

  

  
  * You can also turn on the OnSite by pressing the green On/Off button.

STEP 2: PLACE THE PADS

• Pull the tab at the top of the pads cartridge to peel off the film seal.

  

• Inside are two adhesive pads on a plastic liner. Remove the pads from the cartridge.
• Peel one pad off the liner. Place the pad on the patient’s bare skin, exactly as shown in the picture on the pad.
• Press the pad down firmly. Then repeat this with the other pad. Be sure the pads have been removed from the liner before placing them.

• Where to place pads on adults (anterior-anterior).

  

• Where to place pads on infants or children under 55 pounds/25 kg or 8 years old (anterior-posterior).

  

STEP 3: PRESS THE SHOCK BUTTON
As soon as the OnSite detects that the pads are attached to the patient, it begins analyzing the patient’s heart rhythm. It tells you that no one should be touching the patient, and the Caution light begins flashing as a reminder.

If a shock is needed: 
The Caution light goes from flashing to solid, the orange Shock button starts flashing, and the OnSite tells you to press the flashing orange button. Before you press the button, make sure no one is touching the patient. When you press the Shock button, the OnSite tells you that the shock has been delivered. Then the OnSite tells you it is safe to touch the patient, instructs you to begin CPR, and invites you to press the flashing blue i-button for CPR guidance if desired.

If a shock is not needed: 
The OnSite tells you it is safe to touch the patient and instructs you to perform CPR if needed. (If CPR is not needed – for example, if the patient is moving or regaining consciousness – follow your local protocol until emergency medical personnel arrive.) Then the OnSite invites you to press the flashing blue i-button for CPR guidance, if desired.

For CPR guidance: 
Press the flashing blue i-button during the first 30 seconds of the patient care pause to activate CPR guidance.* (If the Infant/Child SMART Pads Cartridge is inserted, CPR guidance will provide guidance for infant/child CPR.) When the pause is over, the OnSite tells you to stop CPR, so it can analyze the patient’s heart rhythm. The motion caused by CPR can interfere with analysis, so be sure to stop all motion when instructed.

* The default configuration for the OnSite provides CPR guidance when you press the i-button in this situation; however, the default setting can be revised by your Medical Director using Philips software available separately. See Appendix E for more information.

TREATING INFANTS AND CHILDREN

WARNING: Most cardiac arrests in children are not caused by heart problems. When responding to cardiac arrest in an infant or child:

• Provide infant/child CPR while a bystander calls EMS and brings the OnSite.
• If no bystander is available, provide 1-2 minutes of CPR before calling EMS and retrieving the OnSite.
• If you witnessed the child's collapse, call EMS immediately and then get the OnSite.

Alternatively, follow your local protocol.

If the patient is under 55 pounds (25 kg) or 8 years old, and you have an infant/child SMART Pads Cartridge:

• Remove the Infant/Child SMART Pads Cartridge from its package.*
• Locate the latch at the top edge of the defibrillator, and slide it to the side. Any installed SMART pads cartridge will be released. Remove the old cartridge.
• Install the new infant/child SMART Pads Cartridge: slide the bottom end of the cartridge into the recess, then press in the cartridge until the latch clicks into place. Be sure the green handle is pressed down firmly. The OnSite will tell you that infant/child pads have been inserted, then it will turn off to be ready for use.
• Pull the green handle to start the rescue.
• Remove all clothing from the upper body, to bare both the chest and the back. Place one pad in the center of the chest between the nipples, and the other in the center of the back (anterior-posterior).

With the infant/child SMART Pads Cartridge inserted, the OnSite automatically reduces the defibrillation energy from the adult dose of 150 Joules to 50 Joules† and provides optional infant/child CPR guidance. Place the pads exactly as shown on the illustration on the pads.

* Philips recommends that the OnSite be stored with an adult pads cartridge installed, as pediatric cardiac arrest is not common.
† This lower energy level may not be effective for treating an adult.

If the patient is under 55 pounds (25 kg) or 8 years old, but you do NOT have an infant/child SMART Pads Cartridge:

• DO NOT DELAY TREATMENT.
• Remove all clothing from the torso, to bare both the chest and the back.
• Apply the OnSite using the adult SMART pads cartridge, but place one pad in the center of the chest between the nipples, and the other in the center of the back (anterior-posterior).

If the patient is over 55 pounds (25 kg) or 8 years old, or if you are not sure of the exact weight or age:

• DO NOT DELAY TREATMENT.
• Remove all clothing from the chest.
• Apply the OnSite using the adult SMART pads cartridge, and place the pads as illustrated on the pads (anterior-anterior). Make sure the pads do not overlap or touch each other.

WHEN EMERGENCY MEDICAL SERVICES ARRIVE
When Emergency Medical Services (EMS) personnel arrive to care for the patient, they may decide to apply another defibrillator to allow monitoring of the patient. The SMART Pads should be removed from the patient prior to using another defibrillator. EMS personnel may want a summary of the last-use data* stored in the OnSite. To hear the summary data, hold down the i-button until the OnSite beeps.

NOTE: After the EMS team removes the SMART Pads from the patient, remove the used SMART pads cartridge, and insert a new SMART pads cartridge before returning the OnSite to service, to be sure it is ready for use.

REMINDERS

• Remove any medicine patches and residual adhesive from the patient’s chest before applying the pads.
• Do not allow the pads to contact other electrodes or metal parts that are in contact with the patient.
• Avoid placing the pads directly over an implanted pacemaker or defibrillator. A noticeable lump with a surgical scar should indicate the position of an implanted device.
• If the pads do not stick well, check that the pads adhesive has not dried out. Each pad has a layer of adhesive gel. If the gel is not sticky to the touch, replace the pads with a new set.
• Keep the patient still and keep any movement around the patient to a minimum during rhythm analysis. Do not touch the patient or the pads while the Caution light is on solid or flashing. If the OnSite is unable to analyze due to electrical “noise” (artifact), it will tell you to stop all movement and remind you not to touch the patient. If the artifact continues for more than 30 seconds, the OnSite will pause briefly to allow you to deal with the source of the noise, then resume analysis.
• The OnSite will not deliver a shock unless you press the flashing orange Shock button. If you do not press the Shock button within 30 seconds after the OnSite tells you to, it will disarm itself, and (for the first CPR interval) give a reminder to make sure emergency medical services have been called, then begin a CPR interval. This is designed to minimize interruption of CPR and help ensure ongoing patient support.
• While waiting for you to press the Shock button, the OnSite will continue to analyze the heart rhythm. If the patient’s rhythm changes before you press the Shock button, and a shock is no longer needed, the defibrillator will disarm and tell you a shock is not advised.
• If for any reason you want to turn off the defibrillator during a use, you can press the On/Off button – holding it down for at least one second – to return the device to standby mode.

Setup Guide

To set up and operate the Philips HeartStart OnSite Defibrillator M5066A, follow these steps:

1. Ensure the device is properly charged and that the SMART Pads cartridge is installed correctly.
2. In the event of a cardiac emergency, turn on the device by pressing the green button.
3. Follow the voice prompts and visual instructions to prepare the patient for defibrillation.
4. Apply the SMART Pads to the patient's bare chest as directed by the device.

MAINTAINING THE HEARTSTART ONSITE

ROUTINE MAINTENANCE 
The OnSite is very simple to maintain. The OnSite performs a self-test every day. In addition, a battery insertion self-test is run whenever a battery is installed in the device. The OnSite’s extensive automatic self-test features eliminate the need for any manual calibration. The OnSite has no user-serviceable parts.

WARNING: Electrical shock hazard. Do not open the OnSite, remove its covers, or attempt repair. There are no user-serviceable components in the OnSite. If repair is required, return the OnSite to Philips for service.

REMINDERS:

• Do not leave the OnSite without a SMART pads cartridge installed; the OnSite will start chirping and the i-button will start flashing. For directions on changing the pads cartridge, see Chapter 4, “After Using the HeartStart OnSite.”
• The OnSite runs daily self-tests. As long as the green Ready light is blinking, it is not necessary to test the OnSite by initiating a battery insertion self-test. This uses battery power and risks draining the battery prematurely.

PERIODIC CHECKS
Other than the checks recommended after each use of the OnSite, maintenance is limited to periodically checking the following:

• Check the green Ready light. If the green Ready light is not blinking, see Troubleshooting Tips, below.
• Replace any used, damaged or expired supplies and accessories.
• Check the outside of the OnSite. If you see cracks or other signs of damage, contact Philips for technical support.

Record each periodic check in your inspection log/maintenance booklet.

CLEANING THE ONSITE

The outside of the OnSite and its carry case can be cleaned with a soft cloth dampened in soapy water, chlorine bleach (2 tablespoons per quart or liter of water), or ammonia-based cleaners.

REMINDERS:

• Do not use isopropyl (rubbing) alcohol, strong solvents such as acetone or acetone-based cleaners, abrasive materials, or enzymatic cleaners to clean your OnSite.
• Do not immerse the OnSite in fluids or allow fluids to spill onto it.
• Do not sterilize the OnSite or its accessories.

TESTING

• As long as a battery is installed, the HeartStart OnSite Defibrillator automatically tests itself every day and alerts you if it finds a problem. The selftest includes pads readiness testing. In addition, it runs a pads self-test each time a SMART pads cartridge is inserted. It alerts you if it finds a problem.
• You can also test the OnSite at any time by removing the battery for five seconds then reinstalling it. This test takes about one minute. Because the battery insertion self-test is very detailed and uses battery power, running it more often than necessary will drain the battery prematurely. It is recommended that you run the battery insertion self-test only:
  • when the OnSite is first put into service.
  • after each time the OnSite is used to treat a patient.
  • when the battery is replaced.
  • when the OnSite may have been damaged.
• If you need to use the OnSite in an emergency while you are running a battery self-test, pull the SMART Pads Cartridge handle to stop the test and to turn on the OnSite for use.

TROUBLESHOOTING

The OnSite’s green Ready light is the signal that tells you if the OnSite is ready for use. The OnSite also uses chirps and the i-button flashes to alert you to a problem.
RECOMMENDED ACTION DURING AN EMERGENCY 
If for any reason the OnSite does not turn on when you pull the SMART Pads Cartridge handle, press the On/Off button. If that does not turn on the OnSite, remove the battery and replace it with a new battery if available and press the On/Off button to turn on the OnSite. If no spare battery is available, remove the installed battery for five seconds, then reinsert it and run a battery insertion self-test.

If the problem continues, do not use the OnSite. Attend to the patient, providing CPR if needed, until Emergency Medical Services Personnel arrive.
TROUBLESHOOTING WHILE THE ONSITE IS IN USE
(green Ready light is solid)

TROUBLESHOOTING WHILE THE ONSITE IS NOT IN USE
(green Ready light is not on)
NOTE: In the event of a triple-chirp alert, even if the failure is cleared by a battery insertion test, please contact Philips for service. In the event of repeated instances of a self-test failure resulting in single-chirp alerts, even if such failures are cleared by a battery insertion test, please contact Philips for service.
