The risk of these is higher in people who lost consciousness from the carbon monoxide and older people. Symptoms can include fatigue and pain in muscles. Symptoms related to the nervous system and brain can come on after recovery from carbon monoxide poisoning. This resolves during ascent, which must occur at an appropriately slow rate to avoid decompression sickness Decompression Sickness Decompression sickness is a disorder in which nitrogen dissolved in the blood and tissues by high pressure forms bubbles as pressure decreases. This public health statement tells you about carbon monoxide and the effects of exposure to it. For more information, call the ATSDR Information Center at 1-80. (See also Overview of Diving Injuries.) Air is a mixture of gases. The effects of exposure to any hazardous substance depend on the dose, the duration, how you are exposed, personal traits and habits, and whether other chemicals are present. When an animal inhales smoke, it brings a combination of toxic gases, such as carbon monoxide and hydrogen cyanide, and particulate matter, a mixture of small liquid and solid particles, into its. However, diving with helium at depths greater than 500 to 600 feet can precipitate the high-pressure nervous syndrome High-Pressure Neurologic (Nervous System) Syndrome Problems during diving can result from toxic effects of gases such as nitrogen, oxygen, carbon dioxide, and carbon monoxide. Indoor pets also appear ill, exhibiting symptoms such as drowsiness and lethargy (human flu viruses are not transmitted to pets). CO decreases oxygen saturation in dose-dependent fashion and shifts the oxygen dissociation curve to the left, despite a normal partial pressure of oxygen (PO 2). Low concentrations of oxygen are used, diluted with helium rather than nitrogen, because helium does not cause narcosis. Carbon monoxide absorption in plasma is diffusion-limited and binds 200 to 250 times more avidly to hemoglobin than oxygen, effectively displacing oxygen from heme-binding sites. To minimize these effects, divers who must dive to great depths typically breathe a special mixture of gases rather than regular air.
