The normal range of respiration for most residents is typically between 12 to 20 breaths per minute. This range is considered standard for adults at rest and indicates that the body's respiratory system is functioning effectively to meet metabolic demands.

Monitoring respiration is a crucial part of a CNA's responsibilities, as it provides valuable information about a person's health status. Breathing that falls within this range suggests adequate oxygenation and carbon dioxide exchange. While individual factors such as age, fitness level, and medical conditions can influence respiratory rates, the 12 to 20 breaths per minute range is widely accepted as normal for most adults. Other ranges listed might pertain to specific populations or situations but do not reflect the general standard for healthy adults.
