When artificial respiration is necessary, how soon should it be started?

• A. After 60 seconds
• B. Immediately
• C. After checking for breathing for 10 seconds
• D. Only after calling for help

Answer: (B)

Starting artificial respiration right away is essential because oxygen delivery to the brain and other vital organs falls quickly when breathing stops. Any delay increases the risk of brain injury or death, so you should begin rescue breaths immediately once you determine the person is not breathing (and if needed, perform a quick breathing check without letting that delay your action). If you can, call for help right away, but don’t wait for the call to begin providing breaths. Continue giving breaths at a steady, appropriate rate until the person resumes normal breathing or professional help arrives.
