Final answer:
Special circumstances that may affect AED pad placement and defibrillation include wet or moist chest, hairy chest, and implanted medical devices.
Step-by-step explanation:
AED pad placement and defibrillation can be affected by various special circumstances. Some of these circumstances include:
- Wet or moist chest: If the patient's chest is wet or moist, it can interfere with the electrical conductivity of the pads. In such cases, it is important to dry the chest before applying the pads.
- Hairy chest: Excess hair on the chest can create a barrier between the pads and the skin, reducing the effectiveness of the shock. Shaving the chest or using pads with built-in razors can help overcome this issue.
- Implanted medical devices: If the patient has a pacemaker or an implantable cardioverter-defibrillator (ICD), special precautions must be taken to ensure safe defibrillation. The AED pads should be placed at least 1 inch away from the device to avoid interference.
