Nitrox is a gas mixture with more oxygen than regular air. It helps divers have longer bottom times and shorter surface intervals. Nitrox is safe for sport divers and has become common in diving. This gas can cost more to refill, and divers must monitor oxygen levels. Proper planning and training are important for safe […]

Hyperbaric oxygen therapy (HBOT) is known for treating decompression sickness in divers, but recent studies show it can also help heal brain injuries. A clinical trial found positive results for patients with traumatic brain injuries (TBI) and post-traumatic stress disorder (PTSD). This therapy has shown effectiveness in reducing symptoms and helping over 31,000 patients recover, […]

A new crystal made from cobalt could change scuba diving by allowing divers to breathe without tanks. This crystal absorbs oxygen from the air, up to 160 times more than normal, and can release it when needed. This technology could make diving easier by extracting oxygen from the water, potentially allowing divers to leave their […]

Compression-only CPR, also known as hands-only CPR, is getting renewed attention for its effectiveness in emergencies. It focuses on providing continuous chest compressions without rescue breaths, making it easier to remember and safer for those worried about disease transmission. This method can circulate oxygen to vital organs, and even though it’s not as comprehensive as […]
