Place alarm should have the following features: 1, when the medical air supply, medical vacuum exchange, anesthesia emissions vacuum unit of the main supply compressors, vacuum pump downtime, you should start the alarm; when the spare compressors, vacuum pumps in operation , should start the backup operation alarm 2, medical air supply should be set carbon monoxide alarm, when exceeded triggers an alarm when the carbon monoxide concentration of other symptoms require oxygen therapy body frail people with poor immunity, heat stroke, gas poisoning, drug poisoning. Such as gas poisoning is in a closed room where the use of coal stoves for heating, cooking, bathing the gas water heater for a long time but poor ventilation, prone to gas poisoning accident. After the gas poisoning, people tend to dizziness, nausea, vomiting, palpitation, pale skin, confusion, severe confusion, lockjaw, convulsions, incontinence, appear pale cherry red lips, breathing and pulse fast growth . After oxygen gas poisoning is very important because the higher the concentration of oxygen inhaled oxygen machine maintenance and price, the greater the oxygen partial pressure of carbon monoxide in the blood separation speed, discharge more. Studies have shown that oxygen, carbon monoxide in the blood half-time in the indoor oxygen machine industry need 200 minutes, it takes 40 minutes inhaling pure oxygen. So the application of hyperbaric oxygen treatment of carbon monoxide poisoning is the most effective way. Patients were placed in the 2 to 2.5 atmospheres hyperbaric chamber medical air separation oxygen plant, after 30 to 60 minutes, blood carboxyhemoglobin can be reduced to zero, and heart damage does not occur.
