Respiratory rate reporting.
The respiratory rate is a valuable component of patients' vital signs. Abnormal rates may indicate direct cardiopulmonary diseases, adverse responses to drugs, and compensating responses to acid-base abnormalities. Furthermore, a rate of more than 20 is 1 of the 4 defined criteria for systemic inflammatory response syndrome (SIRS). The other 3 SIRS criteria include a temperature higher than 38°C or lower than 36°C; pulse of more than 90/min; and a white blood cell count of more than 12 × 109/L, less than 4 × 109/L, or with more than 10% bands [1].
