Acute respiratory acidosis occurs when an abrupt failure of ventilation occurs. This failure in ventilation may be caused by depression of the central respiratory center by cerebral disease or drugs, inability to ventilate adequately due to neuromuscular disease (e.g., myasthenia gravis, amyotrophic lateral sclerosis, Guillain–Barré syndrome, muscular dystrophy), or airway obstruction ...
k H CO 2 is a constant including the solubility of carbon dioxide in blood. k H CO 2 is approximately 0.03 (mmol/L)/mmHg; p CO 2 is the partial pressure of carbon dioxide in the blood; Combining these equations results in the following equation relating the pH of blood to the concentration of bicarbonate and the partial pressure of carbon ...
Hypocapnia also results in bronchoconstriction [3] in order to decrease ventilation. This mechanism is meant to counteract hyperventilation, and decrease the amount of oxygen coming into the lungs. The body's "goal" is to have a relatively even ratio of the partial pressure of oxygen to the partial pressure of carbon dioxide.
Blood gases of a patient with Kussmaul breathing will show a low partial pressure of CO 2 in conjunction with low bicarbonate because of a forced increased respiration (blowing off the carbon dioxide). Base excess is severely negative. The patient feels an urge to breathe deeply, an "air hunger", and it appears almost involuntary.
Likely factors in the development of cerebral edema are dehydration, acidosis and low carbon dioxide levels; in addition, the increased level of inflammation and coagulation may, together with these factors, lead to decreased blood flow to parts of the brain, which then swells up once fluid replacement has been commenced.

Metabolic acidosis is a serious electrolyte disorder characterized by an imbalance in the body's acid-base balance.Metabolic acidosis has three main root causes: increased acid production, loss of bicarbonate, and a reduced ability of the kidneys to excrete excess acids. [5]

A decreased respiratory drive can also be the result of metabolic alkalosis, a state of decreased carbon dioxide in the blood; Central sleep apnea. During sleep, the breathing centers of the brain can pause their activity, leading to prolonged periods of apnea with potentially serious consequences. Hyperventilation followed by prolonged breath ...
