@mikeJB Increase of blood ph or basicity of blood results in alkalosis which is harmful. But considering your blood ph it seems perfectly normal to me as alkalosis occurs when blood ph exceeds ph levels of about 7.45 or 7.5 and increase in CO2 concentration takes place in acidosis when your blood ph drops below a certain level(i think below 7.3) so according to your blood ph i think you're quite fine.
