Breathing into and out of a paper bag for a long period of time will lead to?
Ilya [14]

Breathing into and out of a paper bag for a long period of time will lead to respiratory acidosis.

<h3>What is respiratory acidosis?</h3>
  • When the lungs are unable to expel all of the carbon dioxide the body produces, a condition known as respiratory acidosis develops.
  • Body fluids, particularly the blood, become too acidic as a result.
  • The main causes of respiratory acidosis are inadequate ventilation and carbon dioxide buildup.
  • The main issue is an increase in arterial carbon dioxide partial pressure (pCO2) and a decline in the arterial bicarbonate to arterial pCO2 ratio, which causes a drop in blood pH.
  • When there is acute respiratory acidosis, the body initially tries to make up for it.
  • If the acidosis lasts more than 12 hours, a reaction known as metabolic compensation2 takes place.
  • By increasing the release of hydrogen ions through ammonium, the kidneys will lower the blood's acidity.
  • Too much carbon dioxide in the body can result in general symptoms including headache, exhaustion, and twitching muscles.
  • Frequently, it goes away fast on its own.
  • But in cases of severe hypercapnia, the body is unable to return to a stable CO2 level, and the symptoms are more severe.
