When recording the respiration rate in a medical record, the typical format is to write the number of breaths per minute followed by the abbreviation "bpm" (breaths per minute). For example, if the patient has a respiration rate of 20 breaths per minute, it would be recorded as "20 bpm". It is important to record the date and time of the measurement, as well as the patient's name and other relevant information, such as their medical history or any medications they are taking. Additionally, any observations or notes about the patient's condition at the time of the measurement should be included in the medical record.
