Coughing is typically the first symptom of pulmonary oxygen toxicity. An oxygen concentrator—a device that pulls oxygen from the air around you—is a helpful option for those who use oxygen therapy, as it eliminates some of the tasks you have if you use an oxygen tank, such as monitoring remaining levels and getting timely replacements. That being said, with oxygen therapy, one needs to be doubly careful and be aware of the risks and dangers as well. readmore 02 /8 Tips to keep in mind while following home-based oxygenation 67 “CO2 cylinders at user’s premises” for more details about the additional hazards of carbon dioxide). Diving with and handling nitrox raise a number of potentially fatal dangers due to the high partial pressure of oxygen (ppO 2). A common hazard in a health care facility is storing and handling compressed oxygen in cylinders. The risk for this side effect of oxygen therapy comes into play primarily when patients on home treatment increase the oxygen flow rate to a level higher than prescribed. Nitrox is not a deep-diving gas mixture owing to the increased proportion of oxygen, which becomes toxic when breathed at high pressure. 4.1 Oxygen is essential for life Oxygen is the only gas that supports life. NFPA 99, Health Care Facilities Code minimizes these hazards by defining optimum design and construction of cylinder storage locations as well as safe operation and handling of the cylinders. Associated health risks include burns, electrocution, suffocation and asphyxiation, poisoning, crush injuries, brain damage and death. The normal concentration of oxygen in the air we breathe is approximately 21 %. The main hazards presented by this type of work environment are lack of oxygen, toxic or flammable and explosive vapours, engulfment and mechanical equipment. Portable oxygen tanks are small aluminum cylinders that carry compressed oxygen gas or liquid oxygen that turns into a gas. The risk of pulmonary oxygen toxicity proves highest when inhaling pure oxygen for several hours to days. As more oxygen is stored in cylinders, the hazard increases. The contents of an oxygen tank are under extreme pressure, which allows you to get a constant flow of oxygen until the tank is empty. (See IGC Doc.
