Respiratory Rate

For education. Check every result.

Anatium is a study resource, not medical advice. Nothing here is a diagnosis, a prescription or a substitute for a clinician who has seen the patient. Check every number against a current local protocol before it touches anyone, and never act on a result you cannot reproduce yourself.

Reference range

Adolescent & adult (12+ years)12 to 20 /min
Child (1-12 years)18 to 30 /min
Infant (<1 year)30 to 60 /min
Neonate (<28 days)40 to 60 /min

About

Breaths per minute, and the most neglected observation on the chart. A rising rate is often the FIRST sign of deterioration, hours before pulse or blood pressure move.

When it is low

Bradypnea: May indicate CNS depression, opioid overdose, metabolic alkalosis, or hypothyroidism

When it is high

Tachypnea: May indicate hypoxia, pain, anxiety, fever, metabolic acidosis, PE, or pneumonia

How it is measured

Count for 30 sec × 2. Observe depth and pattern. Most sensitive early warning sign.
