What to do if someone collapses at home? Cardiac surgeon shares steps to take in the first 5 minutes

Knowing what to do when someone collapses at home can save a life. Dr. Santosh Gupta, a cardiac surgeon, shares the immediate steps to take in the first five minutes.

First, call emergency services. Then, check the person's breathing and pulse. If they're not breathing, start chest compressions. If they're breathing, open their airway and give rescue breaths.

While these skills are universally useful, they are particularly important for seafarers who may be far from immediate medical help.
