Final answer:
The normal rescue breathing rate without an endotracheal tube for adults is 12 to 15 breaths per minute, but varies with age. For infants, it is 30 to 60 breaths per minute, for children around 10 years old is 18 to 30 breaths per minute, and by adolescence, it decreases to an adult breathing rate. This rate is important for effective alveolar ventilation.
Step-by-step explanation:
The normal rescue breathing rate for a person without an endotracheal tube is approximately 12 to 15 breaths per minute for adults. For children, this rate is higher and decreases from birth to adolescence. Infants under 1 year of age normally breathe at a rate of 30 to 60 breaths per minute, while a child around 10 years old has a normal respiratory rate of 18 to 30 breaths per minute. By adolescence, it decreases further to match the adult rate of 12 to 18 breaths per minute. These breathing rates are essential for maintaining alveolar ventilation, which is crucial to prevent carbon dioxide buildup in the alveoli and ensure the body receives sufficient oxygen.
When performing rescue breathing on someone, it is vital to maintain this normal rate to ensure the individual receives the proper amount of oxygenated air. The rescue breathing rate should be adjusted based on the individual's age group to closely simulate normal breathing patterns.
