For a 14-year-old in cardiac arrest, what age group techniques and equipment should be used?

For a 14-year-old in cardiac arrest, techniques and equipment appropriate for the adult age group should be used. This is because at the age of 14, a person is typically closer in physiological development to adults than to children or infants. The adult protocols take into account the size, strength, and anatomical differences that exist in individuals who have already reached their adolescent stage. When performing CPR or using an AED (Automated External Defibrillator) on someone who is 14, responders should follow the guidelines established for adults to ensure effective care.

Using techniques designed for younger age groups, such as those intended for infants or children, may not provide sufficient force or depth for effective compressions, nor would it adequately account for the specific physiological needs of a teenager. Therefore, adult techniques are essential for performing effective lifesaving measures in a 14-year-old in cardiac arrest.
