Hypercapnia (from the Greek hyper, "above" or "too much" and kapnos, "smoke"), also known as hypercarbia and CO 2 retention, is a condition of abnormally elevated carbon dioxide (CO 2) levels in the blood. Carbon dioxide is a gaseous product of the body's metabolism and is normally expelled through the lungs.
Normocapnia or normocarbia is a state of normal arterial carbon dioxide ... tissue carbon dioxide levels; Hypocapnia – State of reduced carbon dioxide in the blood;
With the lower level of carbon dioxide, to keep the pH at 7.4 the kidneys secrete hydrogen ions into the blood and excrete bicarbonate into the urine. [ 50 ] [ 51 ] This is important in acclimatization to high altitude .
The carbon dioxide content of the blood is often given as the partial pressure, which is the pressure which carbon dioxide would have had if it alone occupied the volume. [73] In humans, the blood carbon dioxide contents are shown in the adjacent table.
Under most conditions, the partial pressure of carbon dioxide (PCO 2), or concentration of carbon dioxide, controls the respiratory rate. The peripheral chemoreceptors that detect changes in the levels of oxygen and carbon dioxide are located in the arterial aortic bodies and the carotid bodies. [2]
Carbon dioxide is a by-product of food metabolism and in high amounts has toxic effects including: dyspnea, acidosis and altered consciousness. [8] Arterial blood carbon dioxide tension. P a CO 2 – Partial pressure of carbon dioxide at sea level in arterial blood is between 35 and 45 mmHg (4.7 and 6.0 kPa). [9] Venous blood carbon dioxide tension
[citation needed] For example, a person with increased minute volume (e.g. due to hyperventilation) should demonstrate a lower blood carbon dioxide level. The healthy human body will alter minute volume in an attempt to maintain physiologic homeostasis. A normal minute volume while resting is about 5–8 liters per minute in humans. [1]
