Decompression 1

What is a decompression chamber? **Decompression chamber** (English Decompression Chamber, DEC) is a part of the complex for diving and underwater work, which provides periodic stops and a decrease in pressure in the breathing mixture - unloading nitrogen (exhaled gases) from the body. If a diver spends the entire day underwater or surfaces for a long time or frequently, then the physiological state of the diver causes significant negative consequences. Such as headache, muscle spasms, nausea, decreased performance. All these sensations cause discomfort both during work and when returning to base, in order to relieve stress you need to take medicine or tea, this is not a solution to the problem. Rest and restoration of lost depth can only be obtained by undergoing decompression after a dive.

There are two types of decompression chambers. With low power and high power – sporty. Strong athletes need more powerful equipment; the camera can be changed to another without increasing the price for diving. Most divers can safely use these cameras without any questions from hotel receptionists or dive technicians.

Decompression (recompression) is the reverse process of ascent. This is a set of measures aimed at returning normal gas pressure to the environment, which ensures the safe movement of the worker to the surface and stay on it.

Based on the time of implementation, the following types of recompression are distinguished: - Accelerated. Carried out in the event of an accident or deterioration of the victim’s condition. It is carried out by pumping air into the pockets of a suit or a cylinder. Decompression chambers: * Used in case of damage to the protective circuit (tent, oxygen mask, etc.). * Necessary for deep decompression * Allows you to quickly restore acceptable pressure without the use of a cylinder or gas systems * Made of stainless metal - Emergency. When the living compartment of an underwater vehicle is depressurized. First of all, those being saved are provided for, then everyone else. Use of compressed air cylinders in gas-hazardous hand pumps or oxygen apparatuses;

For minor decompression sickness! - Shallow (reason - work in a polluted atmosphere at high pressure). Includes rehabilitation and preventive treatment. . It takes up to 2 weeks, involves physical exercises and wearing an oxygen tank while breathing. ! - Severe (causes: partial or complete cessation of pulmonary ventilation or prolonged respiratory hypoxia occurring without a protective atmosphere). It is carried out under conditions of artificial lung ventilation, as well as when using equipment and devices to rescue people who have lost consciousness or are in an unconscious state. Helps establish normal blood pressure. Using 5 cylinders, inhalation is carried out (an oxygen mixture of 90% oxygen and 10% carbon dioxide), this process allows you to saturate the tissues with oxygen, even if the victim has no symptoms. The procedure allows you to maintain consciousness and reduce the load on the respiratory system. But before using resuscitation methods, it is recommended to check for circulatory arrest. To do this, the pulse is checked and the condition of the pupils is checked. Medicines prescribed during the incubation period: angiotensinamide acetylcysteine, an antihistamine, drugs that cause diuresis and diuretic effects; for hydrocephalic syndrome, levodopa and methyldopa are recommended; for hyperthermia - amidopyrine, butazol, dipyridol. Potassium chloride, thiamine, dipotassium chloride, and mucolytics are also used; after an hour after hyperbaric oxygenation, you can begin decongestant procedures (administration of diuretics in large doses, diuretics, administration of anticholinesterase, use of aminophylline). The prevention of cerebral edema is carried out using accelerated methods: using diuretics, cardiac glycosides, glucose and insulin. Treatment of decompressive illness involves a great risk to the life of the victim, so it should only be carried out by a specialist.
