Is the 30:2 ratio for compressions and breaths applicable in all cases?

April 5, 2026

Quick Answer

The 30:2 ratio is primarily recommended for adult CPR, but variations exist for pediatric, infant, and newborn CPR. The American Heart Association has adjusted the compression-to-breath ratio based on age and other factors.

CPR Variations by Age Group

When it comes to CPR, the age of the patient is a crucial factor in determining the correct compression-to-breath ratio. For adults, the 30:2 ratio is the standard, but for children, the ratio is typically 30:2 as well. However, the American Heart Association recommends a 15:2 ratio for children weighing 40-59 pounds (18-27 kilograms) and a 30:2 ratio for children weighing 60 pounds (27 kilograms) or more.

BLS and ACLS Guidelines

For Basic Life Support (BLS) and Advanced Cardiovascular Life Support (ACLS) guidelines, the 30:2 ratio is generally recommended for adult CPR. However, for pediatric patients, the 15:2 ratio may be more suitable. In addition, for newborns (0-1 month), the compression-to-breath ratio is 3:1 for 30 minutes, with a focus on compressions rather than breaths.

Infant and Newborn CPR

For infants (1-12 months), the American Heart Association recommends a compression of 30:2 with a focus on chest compressions. Newborn CPR (0-1 month) involves a compression-to-breath ratio of 3:1 for 30 minutes. It’s essential to note that for newborn CPR, the focus should be on compressions rather than breaths. In all cases, CPR should be continued until emergency medical personnel arrive or the patient shows signs of regaining consciousness.
