ACLS review

216.  Is it safe to use an AED in water?
No, it is not safe.  The water conducts electricity.  If the patient is in water, move the patient to a dry surface and wipe off as much water from the skin surface as possible. 

217.  What problems are posed when attempting to use an AED on a patient with a hairy chest?
The hairy chest may prevent the pads from sticking properly to the skin surface.   When this occurs the electricity from the defibrillation is conducted across the skin surface and not through the myocardium.   If too much hair is present, then quickly pull off the pads to remove the hair and reapply fresh pads or use a razor to shave off the hair.

218.  Is the use of an AED contraindicated in patients with an implantable pacemaker or defibrillator?
No, an AED can be safely used in patients with an implantable pacemaker or defibrillator.   In such patients, avoid placing the AED electrode pads over the device.    Place the pads about 1 inch (2.5cm) to either side of the implanted devise.

219.   What are the problems posed when attempting to use an AED on a patient with a medication patch on their chest wall?   If the AED electrode pad is placed on the medication patch, it will block the delivery of current from the AED to the patient’s heart.  In order to prevent this, remove the medication patch and wipe the skin surface free of any residual medication before attempting to attach the AED electrode pad.

220.  What are the general steps for using an AED?
Power on AED
Plug in cord connector
Analyze the rhythm
Shock if indicated
