In the presence of a simple metabolic acidosis of >24 hours duration the lower limit of compensation of PCO2 is usually

In the presence of a simple metabolic alkalosis of >24 hours duration the upper limit of compensation of PCO2 is usually

In the presence of a simple respiratory acidosis, for every 10 mmHg increase in PCO2 the HCO3 would be expected  to increase within 10 minutes by

In the presence of a simple respiratory acidosis, every 10 mmHg increase in PCO2 would be expected  to increase the HCO3 at 4 days by approximately

In the presence of a simple respiratory alkalosis, each 10 mmHg decrease in PCO2 would be expected to decrease HCO3 within 10 minutes by approximately
