3 Types of Chambers - Multiplace - A Monoplace - B Veterinary - C A diver makes a dive to 100 fsw for 10 minutes. What is his repetitive group designation? (Per US Navy Dive Tables) - A diver makes a dive to 60 fsw and stays for 70 min. Is that a dive no-decompression dive? - A diver makes a dive using Nitrox 32 to 130 fsw. What is his/her PPO2 while diving? - A diver makes a dive using Nitrox 40 to 70 fsw. What is his/her PPO2 while diving? - AGE - Blockage of blood supply caused by air bubbles in a blood vessel/heart AGE Symptoms - Loss of consciousness, cessation of breathing, vertigo, convulsions, tremors, loss of coordination, lack of control of bodily functions, numbness, paralysis, extreme fatigue, visual + hearing abnormalities, personality changes, cognitive impairment, nausea/vomiting, bloody sputum, weakness in extremities AGE/DCS Determination: - Timing is critical, 10 minutes= AGE 10 minutes= DCS Air/Gas Embolism - Gas embolisms occur when gas bubbles become trapped within the arteries or veins, HBOT can be used to treat gas embolisms due to the effect of higher ambient pressure on the bubble, reducing its volume. The saturation of oxygen on the damaged tissues causes leukocytes to adhere to endothelium, and creates a much faster healing process for the patient.Are aquatic life injuries mostly due to aggressive actions on the part of the animal? (If not... what are they due to?) - Arterial Inefficiencies: Central Retinal Artery Occlusion - CRAO is a rare eye condition resulting in sudden, painless vision loss. HBOT can be used to treat CRAO by reoxygenating the inner retinal layers of the eye. Sooner the patient is treated, the higher the likelihood of improvement in vision. At what depth would your patient be exposed to 2.0 ppO2 while breathing 75% Oxygen? - At what PPN2 do symptoms of nitrogen narcosis become a problem? What is the biggest problem with nitrogen narcosis symptoms? - BIBS - Build in breathing system Boyle's Law (Think of water boiling, P&V inversely related) - A law stating that the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature. P1V1=P2V2 Bubbles get bigger as you get closer to the surface Pressure and volume are inversely proportional Can ACLS be performed while the chamber is at depth? - Carbon Monoxide (CO) - CO poisoning occurs when the carbon monoxide builds up in your blood stream. When there is too much CO in the air, your body will replace the oxygen in your RBC with CO. HBOT has many mechanisms which cure CO poisoning such as the ability to rapidly clear CO from the blood + tissues, as well as dissolving oxygen in the blood.Charles' Law (Charles is watching TV - T&V directly related) - A statement that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant. V1/T1=V2/T2uu Clostridal Myositis + Myonecrosis (Gas Gangrene) - Gas gangrene is a rapidly progressive and invasive clostridial infection of the muscles which causes massive death to tissues and a small degree of gas production. HBOT is used to treat gas gangrene by detoxifying the gaseous tissue.
