Respiratory alkalosis is a medical condition in which increased respiration elevates the ... High altitude areas ... This causes decreased circulating hydrogen ion ...
However, hyperpnea also causes the adverse effect of respiratory alkalosis, inhibiting the respiratory center from enhancing the respiratory rate as much as would be required. Inability to increase the breathing rate can be caused by inadequate carotid body response or pulmonary or renal disease.
Altitude sickness, the mildest form being acute mountain sickness (AMS), is a harmful effect of high altitude, caused by rapid exposure to low amounts of oxygen at high elevation. [ 1 ] [ 2 ] [ 3 ] People's bodies can respond to high altitude in different ways.
This respiratory alkalosis reduces the concentration of HCO3 and return plasma pH to normal levels. The respiratory center responds to the stimulation of the peripheral chemical receptors produced by the hypoxia after the kidneys have recover the alkalosis. [14]
Factors that may induce or sustain [2] hyperventilation include: physiological stress, anxiety or panic disorder, high altitude, head injury, stroke, respiratory disorders such as asthma, pneumonia, or hyperventilation syndrome, [5] cardiovascular problems such as pulmonary embolisms, anemia, an incorrectly calibrated medical respirator, [1] [3 ...
Altitude sickness, also known as acute mountain sickness (AMS), altitude illness, hypobaropathy, or soroche, is a pathological effect of high altitude on humans, caused by acute exposure to low partial pressure of oxygen and respiratory alkalosis arising from low partial pressure of blood carbon dioxide caused by hyperventilation. [11]
The equipment must supply breathing gas for all users for at least 15 minutes at a cabin altitude of 8,000 ft at a respiratory minute volume of 30 liters per minute, either by continuous flow or via a demand system, and must not cause a significant increase in oxygen content of the local environment. [25]
At high altitude, the partial pressure of oxygen is lower and people have to breathe more rapidly to get adequate oxygen. When this happens, the partial pressure of CO 2 in the lungs (pCO 2 ) decreases (is "blown off"), causing a respiratory alkalosis .
