Answer
1) Non compensated metabolic acidosis
a) pH is low
b) Bicarbonate ion is low
c) PCO2 level is normal
2) Compensatory mechanism
a) Intracellular compensation
- Potassium- hydrogen ion exchanges (H+ enters cell, K+ exits cell)
b) Respiratory mechanism
- Increase in ventilation to get rid of CO2 (Hyperventilation) after chemoreceptors sense a deranged acid-base system
c) Renal mechanism (longer course, after 3-4 days)
- Renal excretion of Hydrogen ion
- Potassium- hydrogen ion exchanges (H+ enters cell, K+ exits cell)
- Kidney tries to conserve bicarbonate ion.
