What does the "B" in ABC refer to?

The "B" in ABC stands for Breathing, which is a critical component of assessing and managing a patient’s airway and circulation. In the context of emergency care, the ABCs represent a sequence used to prioritize actions to ensure vital functions are maintained or restored.

Breathing involves checking for adequate air exchange and the effectiveness of ventilation. If a patient is unable to breathe adequately, this can lead to hypoxia and significantly threaten life. Assessing breathing includes checking for signs of respiratory distress, measure the rate and quality of breaths, and look for any obstructions or issues that may compromise airflow.

Proper management of breathing is essential alongside airway management and ensuring circulation is intact, highlighting the interconnectedness of these factors in emergency medical response.
