Treatment of diving<unk>  depends on the symptoms. Lung over-pressure injury may require a chest drain to remove air from the pleura or mediastinum. Recompression with hyperbaric oxygen therapy is the definitive treatment for arterial gas embolism, as the raised pressure reduces bubble size, low inert gas partial pressure accelerates inert gas solution and high oxygen partial pressure helps oxygenate tissues compromised by the emboli. Care must be taken when recompressing to avoid a tension pneumothorax.<unk> s that do not involve gas in the tissues are generally treated according to severity and symptoms for similar trauma from other causes. First aid Pre-hospital care for lung<unk>  includes basic life support of maintaining adequate oxygenation and perfusion, assessment of airway, breathing and circulation, neurological assessment, and managing any immediate life-threatening conditions. High-flow oxygen up to 100% is considered appropriate for diving accidents. Large-bore venous access with isotonic fluid infusion is recommended to maintain blood pressure and pulse. Emergency treatment Pulmonary<unk> : * Endotracheal intubation may be required if the airway is unstable or hypoxia persists when breathing 100% oxygen. * Needle decompression or tube thoracostomy may be necessary to drain a pneumothorax or haemothorax * Foley catheterization may be necessary for spinal cord AGE if the person is unable to urinate. * Intravenous hydration may be required to maintain adequate blood pressure. * Therapeutic recompression is indicated for severe AGE. The diving medical practitioner will need to know the vital signs and relevant symptoms, along with the recent pressure exposure and breathing gas history of the patient. Air transport should be below if possible, or in a pressurized aircraft which should be pressurised to as low an altitude as reasonably possible. Sinus squeeze and middle ear squeeze are generally treated with decongestants to reduce the pressure differential, with anti-inflammatory medications to treat the pain. For severe pain, narcotic analgesics may be appropriate. Suit, helmet and mask squeeze are treated as trauma according to symptoms and severity. Medication The primary medications for lung<unk>  are oxygen, oxygen-helium or nitrox, isotonic fluids, anti-inflammatory medications, decongestants, and analgesics. Outcomes Following<unk>  of the ears or lungs from diving the diver should not dive again until cleared by a diving doctor. After ear injury examination will include a hearing test and a demonstration that the middle ear can be autoinflated. Recovery can take weeks to months.
