The assessment of breathing and ventilation specifically focuses on the respiratory rate (RR) because it directly measures the number of breaths a person takes per minute. This metric is crucial for evaluating a patient’s respiratory function, as increases or decreases in the respiratory rate can indicate various conditions such as respiratory distress, metabolic issues, or neurological deficits. By monitoring respiratory rate, healthcare providers can gain valuable insights into the patient’s overall respiratory status and the effectiveness of their ventilation.

While heart rate, pulse oximetry, and capillary refill time are important vital signs and provide useful information about the cardiovascular system and overall oxygenation, they do not specifically convey information about the breathing mechanics or ventilation itself. Therefore, in the context of assessing breathing and ventilation, the respiratory rate is the most relevant component.
