Respiration rate is the number of breaths taken per minute, indicating how well the body is taking in oxygen and expelling carbon dioxide.

Front

What are physical signs?

Back

Physical signs are observable indicators of a patient's health status, such as skin color, temperature, and pulse.

Front

What are symptoms?

Back

Symptoms are subjective experiences reported by the patient, such as pain or fatigue, that indicate a potential health issue.
