What is the expected respiratory rate for an adult casualty?

The expected respiratory rate for a healthy adult at rest typically falls within the range of 12 to 20 breaths per minute. This range is considered normal for a resting adult and is used as a guideline in assessing respiratory function in clinical settings. A rate below 12 breaths per minute may indicate respiratory depression, while a rate above 20 breaths per minute could signal conditions such as anxiety, exercise, or respiratory distress.

It's essential for medical personnel to understand these ranges to accurately assess a casualty's condition and respond appropriately. This knowledge allows for early identification of potential respiratory problems, guiding further intervention or monitoring as needed.
