WebDec 7, 2015 · Dr. Laura Arbogast answered. Yes: Actually, since you're at high altitude the low pressures cause you to breathe faster to get enough oxygen and therefore you're blowing off co2 at a faster rate which results in a respiratory alkalosis. This can be prevented by a medication called Diamox ( acetazolamide) and also controlling how high … WebRespiratory alkalosis. Respiratory alkalosis is defined as a disease state where the arterial blood pH rises into the alkaline range greater than 7.45 secondary to alveolar hyperventilation or sustained tachypnea or hyperpnea (breathing more deeply with or without an increased rate of breathing) 1), 2), 3)..
