Sudden cardiac arrest during exercise is uncommon, but gyms are one of the more likely public places for it to happen, because exertion increases cardiac demand and because gyms concentrate a lot of people doing exactly that. The good news is that a witnessed arrest with immediate CPR and early defibrillation has a genuinely good survival rate.
The person collapses suddenly, is unresponsive, and is either not breathing or is making occasional noisy gasps. Those gasps mislead a lot of people into thinking the person is still breathing. They are not. Agonal gasping is a sign of cardiac arrest, not of recovery. If someone is unresponsive and not breathing normally, treat it as cardiac arrest and start immediately.
Survival falls sharply for every minute without compressions and defibrillation. An ambulance in a metropolitan area may take eight to twelve minutes to reach the gym floor, so the outcome is largely determined by what happens before it arrives. Starting slightly imperfect compressions immediately is far better than starting perfect compressions two minutes later.
Most Australian gyms have a defibrillator, but plenty of trainers working in a facility could not say precisely where it is kept. Find out now, check that the pad expiry date is current, and make sure new staff are shown its location during induction. In a shared building, find out whether there is a closer unit in the lobby or in a neighbouring tenancy.
Document what happened while it is fresh, notify the facility manager, and check on the staff and members who witnessed it. A resuscitation is distressing to watch even when it goes well.
