PFO Concerns in Dive Injury Treatment
If the diver is symptomatic and you are rendering care, then you need to treat the symptoms. Give them the highest concentration of oxygen available, and get them to definitive health care and treatment. Remember that many conditions show symptoms that may mimic DCS. Just because someone was diving does not mean they have a dive-related illness. When creating your emergency action plan, note the location of the nearest emergency room or where and how to access local emergency services.
Introduction to Swim Fitness
Swimming is a noncontact physical activity that lets you be socially distant while still receiving many health benefits. Exercising in water can increase cardiac function, reduce blood pressure and improve muscle blood flow, respiratory function and brain function. Water reduces joint impact, so you can do high-intensity exercise with little to no discomfort from impact. Swimming targets your entire body and allows a greater range of motion for joints than land-based exercise. Blood flows more freely to your upper body, while the water supports you and lowers gravity’s impact.

I removed my gear and was talking to my buddy when I started involuntarily leaning forward until I lost my balance and collapsed face-down on the deck. I felt paralyzed and couldn’t get up.
