“Carbon dioxide (CO2) is a gas the body naturally produces as waste. We breathe in oxygen (O2) to fuel organs and tissues and the end product is CO2. The balance between these two gases is required for a healthy body. However, when we rebreathe CO2 it can have harmful and sometimes dangerous effects on the body.
When CO2 levels are elevated in the body it is known as hypercapnia. Hypercapnia can occur for a number of reasons, one of which is rebreathing our own exhaled CO2. Rebreathing CO2 can lead to increased blood pressure, headaches, muscle twitches, rapid heart rate, chest pain, confusion, and fatigue. In extreme cases, if left untreated, hypercapnia can lead to organ damage and even have long standing effects on the brain.”

Hypercapnia, the elevation of CO2 in blood and tissues, commonly occurs in severe acute and chronic respiratory diseases, and is associated with increased risk of mortality. Recent studies have shown that hypercapnia adversely affects innate immunity, host defense, lung edema clearance and cell proliferation. Airway epithelial dysfunction is a feature of advanced lung disease, but the effect of hypercapnia on airway epithelium is unknown. Thus, in the current study we examined the effect of normoxic hypercapnia (20% CO2 for 24 h) vs normocapnia (5% CO2), on global gene expression in differentiated normal human airway epithelial cells. Gene expression was assessed on Affymetrix microarrays, and subjected to gene ontology analysis for biological process and cluster-network representation. We found that hypercapnia downregulated the expression of 183 genes and upregulated 126. Among these, major gene clusters linked to immune responses and nucleosome assembly were largely downregulated, while lipid metabolism genes were largely upregulated. The overwhelming majority of these genes were not previously known to be regulated by CO2. These changes in gene expression indicate the potential for hypercapnia to impact bronchial epithelial cell function in ways that may contribute to poor clinical outcomes in patients with severe acute or advanced chronic lung diseases.”

“Warning: Exposure to atmospheres containing less than 10% oxygen can rapidly overcome a person and bring about unconsciousness without warning so they are incapable of helping themselves. Lack of sufficient oxygen can cause serious injury or death.”

“Effects of exposure to low oxygen concentrations can include giddiness, mental confusion, loss of judgment, loss of coordination, weakness, nausea, fainting, loss of consciousness and death.
The immediate effects of low oxygen environments are due to our body’s oxygen transport system. Blood absorbs oxygen from the air in our lungs to fuel the cells in our bodies. The brain is the body organ most sensitive to the lack of oxygen.
Within five seconds after inhaling only a few breaths of oxygen-free gas, there is a rapid drop in the oxygen concentration of the blood. Mental failure and coma follow a few seconds later. Symptoms or warnings are generally absent, but even if present, the loss of mental competence, weakness, loss of coordination, or fainting prevents victims from helping themselves or even summoning help. Death follows in just two to four minutes.”
