  Carbon Monoxide a Hidden Hazard
Carbon monoxide is a poisonous gas produced by incomplete combustion of fossil fuels such as oil, gas and coal.
Household carbon monoxide poisoning is usually related to the malfunctioning or improper use of a water heaters, ovens, ranges, furnaces, gas or oil heaters.
Carbon monoxide then may be drawn from the furnace into living spaces when you turn on an exhaust fan or a vented clothes dryer.

  Hypercapnia - Wikipedia, the free encyclopedia
Carbon dioxide is a gaseous product of the body's metabolism and is normally expelled through the lungs.
In closed circuit SCUBA (rebreather) diving, exhaled carbon dioxide must be removed from the breathing system, usually by a scrubber containing a solid chemical compound with a high affinity for CO If not removed from the system, it may be re-inhaled, causing an increase in the inhaled concentration.
The scrubber in the rebreather the diver is failing to remove sufficient carbon dioxide from the loop.

 Carbon Dioxide
This mode of transportation of carbon dioxide is one of the most extraordinary features of the blood and respiration.The evidence for it rests upon 2 facts demonstrated by Pfluger and others during the great epoch of German physiology in the second half of the 19th century.
Carbon dioxide is the chief hormone of the entire body; it is the only one that is produced by every tissue and that probably acts on every organ.
A normal regulation of the carbon dioxide pressure is adequate to compensate either a high or a low blood alkali in practically all conditions compatible with the continuance of life.

 Carbon dioxide poisoning the oceans : Hawai'i IMC
Long-term emissions of carbon dioxide by the world's automobiles, power plants and industries could sharply increase the acidity of the oceans and devastate much of their marine life, scientists at Lawrence Livermore National Laboratory warn.
Carbon dioxide emissions are already known as the biggest offenders in global warming, but the new findings by the scientists at one of the Department of Energy's major laboratories point to a wholly different problem -- the increasing acidity of the world's oceans -- that has received scarcely any public attention.
At current rates, carbon dioxide is entering the atmosphere 50 times more rapidly than it does from natural sources, according to Caldeira, and thus the oceans are rapidly becoming more acidic too.

 Oxygen Poisoning
All this adds to extra carbon dioxide production and the difficulty in getting it out of the body, the problem may be magnified by the increased breathing resistance of a poorly maintained or poorly adjusted regulator, again most modern regulators allow the diver to alter the resistance of the second stage part of the regulator.
At depth the carbon dioxide in the breathing air is breathed at a higher partial pressure and this adds to the impaired expiration of the carbon dioxide from the lungs.
The headaches normally encountered with carbon dioxide poisoning is caused by the dilation of blood vessels in the brain due to the increase in pulse rate and blood pressure, the headache is usually in the front of the skull and can be severe lasting for a few hours after the dive.

 Carbon monoxide poisoning Summary
The main reason to suspect CO poisoning is evidence that fuel is being burned in a confined area, for example a car running inside a closed garage, a charcoal grill burning indoors, or an unvented kerosene heater in a workshop.
Carbon monoxide (CO) is a product of combustion of organic matter under conditions of restricted oxygen supply, which prevents complete oxidation to carbon dioxide.
Carbon monoxide binds to hemoglobin (reducing oxygen transportation), myoglobin (decreasing its oxygen carrying capacity), and mitochondrial cytochrome oxidase (inhibiting cellular respiration).

Rising carbon dioxide levels are increasing the acidity of the world's oceans more rapidly than any time since the age of dinosaurs -- adding a worrisome new element to the debate over global environmental change.
Continuous measurements of carbon dioxide -- an inevitable byproduct of burning coal, oil and natural gas -- have recorded steadily increasing levels of the gas in the atmosphere every year since 1958, a total rise of 17 percent during that period.
At current rates, carbon dioxide is entering the atmosphere 50 times more rapidly than it does from natural sources, according to Caldeira, and thus the oceans are rapidly becoming more acidic too.
