Rescues are exhilarating, tense, and confusing. Your mind will often be racing. We do the best we can based on our training and skill level. Most rescues are sucessful which is great news - we get there eventually. Once the dust has settled, it doesn't hurt to take some time to discuss what happened and think about alternative strategies that may take less time, decrease risk, or less taxing. While evaluating the exercise, take a closer look at things that perhaps didn't go wrong but might have. Did you set safety? Did you use everyone in some useful capacity? Were your first-aid skills current? Great atheletes always look for ways to improve. This is why we practice rescue skills periodically - besides it can be a great deal of fun as well.
