Final answer:
Defibrillation is a medical procedure used during open-heart surgery to restore a normal heart rhythm. The dose for defibrillation using a biphasic monitor can range from 120 to 200 joules. It is important for this procedure to be performed by trained medical professionals.
Step-by-step explanation:
Defibrillation is a medical procedure used during open-heart surgery to bring a patient out of cardiac arrest. It involves delivering an electric shock through a defibrillator monitor to the heart in order to restore a normal heart rhythm. The appropriate dose for defibrillation using a biphasic monitor can vary depending on the specific situation, but it typically ranges from 120 to 200 joules. The exact voltage applied during defibrillation depends on the impedance of the patient's body, which is determined by factors such as current flow and resistance. It is important for this procedure to be performed by trained medical professionals to ensure safety and effectiveness.
