may high/may low

English to French Medical Medical: Health Care dialysis, potassium, electrolytes

EFFECTS OF LOW CONCENTRATION (of potassium)

Arrhythmogenic effect amplified by a rapid
correction of metabolic acidosis, low dialysate
calcium concentration and ****may high**** dialysate
to blood potassium gradient

EFFECTS OF HIGH CONCENTRATION
Risk of insufficient potassium removal with
secondary hyperkalemia in the interdialytic
period due to ****may low**** dialysate to blood
potassium-gradient

This is a booklet for healthcare professionals, about the importance of electrolytes in dialysis.

I can't determine what may high and may low mean, or whether it is a typo/unnecessary word.

Thanks !
