Can you clarify this further?

By hypoxic, do you mean the patient is short of breath?

How do you know the patient is hyperkalemic when missing dialysis? Could s/he not be simply volume overloaded?

I suppose if one was hyperkalemic and it precipitated and arrhythmia leading to heart failure, then I suppose s/he might complain of shortness of breath. But we would require more information to determine this further.

I notice my pt po2 is 87% with hyperkalemia and after dialysis po2 became 94 %

Hello,

An obvious question but are you removing fluid on dialysis? This would be the most likely reason for improvement, that is improvement in pulmonary edema.
