Before placing AED pads, check for transdermal medication patches, like nitroglycerin. Remove any you find from the person’s skin. Always wear gloves during removal to avoid contact with any medication residue.
4. Thick chest hair
For those with thick chest hair, pads must contact the skin. This is vital for effective defibrillation. Shaving the areas for AED pads may be necessary for conductivity.
Understanding AEDs and Sudden Cardiac Arrest
Sudden cardiac arrest is when the heart stops beating suddenly and irregularly. In these critical moments, an automated external defibrillator (AED) can be life-saving. An AED delivers a shock. It helps restore a normal heart rhythm. This gives a chance of survival to the person in need.
Using an AED may seem easy. But, it’s vital to check the user’s manual for safety and maintenance. Knowing these instructions can be vital when helping someone with cardiac arrest.
If you see signs of sudden cardiac arrest, call 911. Have someone get a defibrillator. Then, start CPR right away.
Preparing for AED use in special situations
In some cases, using an AED can be challenging due to the circumstances.
- Excessive chest hair
- Wet or submerged patients
- Pediatric patients
- Patients with implantable devices
- Those with transdermal medication patches
It’s vital to know how to manage these situations. It is key to delivering effective care to a cardiac arrest victim.
Dealing with excessive chest hair.
Excessive chest hair can reduce an AED’s effectiveness. It can prevent the electrode pads from fully sticking to the skin. This lack of contact can weaken the shock delivered. It is especially true if the patient has an implantable defibrillator. This may hinder successful defibrillation.
The AHA’s BLS Provider Manual suggests ways to ensure the electrode pads connect well with the skin. Options include shaving or removing excess chest hair or using a pediatric pad set. These steps help enhance the likelihood of successful resuscitation.
Managing Wet or Water-Submerged Patients
Using an AED on wet or submerged patients is risky. Moisture can reduce the shock’s effectiveness. To maximize the shock’s impact and reach the heart, we must dry the patient’s chest before using the AED pads.
Even if a patient’s chest is dry, it is advisable to move them away from a wet surface before using the defibrillator. This precaution boosts the chances of successful resuscitation. It also ensures the safety of the patient and the rescuers.
AED Use on Pediatric Patients
When using an AED on kids, consider their unique physiology. We must understand these factors to use the device safely and effectively.
- For pediatric patients, a lower electrical shock is recommended. It is safer and more effective for defibrillation.
- If available, always use pediatric pads for children.
- For infants under 12 months, a manual defibrillator is often better. Standard adult pads may not suit this age group.
Correct pad placement is essential for pediatric patients. When using adult pads, one should be positioned in the center of the chest and the other in the middle of the back. By following these guidelines, you can improve the chances of resuscitating a child.
Handling Patients with Implantable Devices
Patients with implantable devices, like pacemakers, pose challenges when using an AED. These devices often leave scars on the chest or abdomen. There may also be a hard lump, the size of a playing card or smaller. If precautions aren’t taken, the AED shock may be blocked. The device could also be damaged during use.
For safety, position the electrode pad a few inches lower. Or, use an anterior-posterior placement. Do not place the defibrillator directly over the pacemaker. Following these guidelines reduces the risk of damaging the implantable device. They also ensure effective defibrillation.
Addressing Transdermal Medication Patches
Transdermal medication patches can burn if someone shocks them with an AED. To reduce this risk, remove the patch. Then, clean any adhesive residue from the skin before applying the AED pads.
Wear gloves while removing the patch. This prevents your skin from absorbing the medication. This precaution ensures your and the patient’s safety when using an AED.
Immediately after providing an AED shock.
After delivering an AED shock, know the immediate actions to take. They are vital for effective life-saving care in emergencies. Following the shock, promptly assess the victim’s breathing and pulse. If there is no pulse or breathing, resume CPR, beginning with chest compressions. If the victim breathes or shows signs of life, place them in the recovery position. Watch them closely until emergency services arrive. Also, keep the AED on. It will guide you and may need to shock again. These steps, taken after a shock, can save a victim. They can also aid recovery.
AED usage tips for non-medical professionals
Although trained for emergencies, medical professionals are not always available. Non-medical people can use an AED effectively during critical situations. AEDs are easy to use. They have clear instructions and voice prompts to guide users.
Knowing the parts of an AED can boost your confidence when using it. These include the razor, pediatric pads, and gloves. Knowing these elements and their functions will help you in an emergency.
