Effect of Inhaling Various Concentrations of CO2 on Electrical Activity of the Heart

Influence of different concentrations of CO2 inhalation on cardiac electrical activity The human body plays an optimum role in a relatively stable environment. Deviations outside the allowable tolerance range can cause unpleasant results. Thus, the dramatic change in the air breathing by humans exerts a devastating effect on the body. Because breathing inhales oxygen and spits out carbon dioxide, breathing is the basis of gas exchange. In some environments such as small enclosed rooms, humans inhale dangerously high concentrations of carbon dioxide when oxygen consumption exceeds production, or when there is a disease like COPD.

Although mass media and public attention focuses on the impact of this high concentration of carbon dioxide on global climate, the rise in carbon dioxide concentration independently extends extensively to plant growth, physiology, chemistry There is a possibility that it may have a negative influence. Climate impact (Ziska 2008). These effects are due to the important role of carbon dioxide in plant metabolism. As photosynthetic organisms, plants absorb carbon dioxide from the atmosphere and chemically reduce carbon. This not only represents the acquisition of plant storage chemical energy but also provides a carbon skeleton for the organic molecules that make up the plant structure. In general, carbon absorbed by organic molecules by photosynthesis accounts for about 96% of the total dry mass of typical plants (Marschner 1995).

Increasing atmospheric carbon dioxide (CO 2) concentration usually exerts two direct and transient physiological effects on plants. First, since the enzyme immobilizes CO 2 at higher CO 2 concentrations, they increase the photosynthetic rate of leaves. Secondly, they partially block pores and reduce water loss due to transpiration. Subsequently, when the plant experiences a long-term increase in CO 2 concentration, a secondary effect can occur. As the respiratory rate decreases or increases, the chemical composition of plants may change, leaf morphology and anatomy may occur.
