<prompt> During acclimatization to high altitude all of the following take place exceptIncrease in minute ventilationIncrease in the sensitivity of central chemoreceptorsIncrease in the sensitivity of carotid body to hypoxiaShift in the oxygen dissociation curve to the left  <response>: At high altitude there can be acute changes and changes due to acclimatization.Acute mountain sicknessDyspnoea, dizziness, tiredness, tachycardia, palpitation, nausea, vomiting etc.At higher altitudes- pulmonary edema and cerebral edema may occur.Acclimatization changesHyperventilation leading to respiratory alkalosisIncreased 2,3DPG- Hb-O2 dissociation curve shifts to right.Increased erythropoietin leading to absolute polycythemiaIncreased renal excretion of bicarbonateIncreased tissue vascularityIncreased oxidative metabolismIncreased diffusion capacity of lungIncreased myoglobin
