How is breathing rate calculated on victims in the field?

Breathing rate in victims is commonly calculated by counting the number of chest rises within a specific time period, and the method of counting the number of chest rises in 15 seconds and then multiplying that number by four provides a quick and efficient way to estimate the number of breaths per minute. This approach allows for a straightforward assessment, as it requires only a short observation period, making it practical and less intrusive, particularly in emergency situations where time is of the essence.

Using this method ensures that the calculation is made by assessing visible indicators of respiration, which can be critical in assessing the victim's condition. In emergencies, rapid decisions often need to be made, and finding a quick way to ascertain the breathing rate helps in prioritizing treatment and interventions.
