Impact of Different Serum Potassium Levels on Postresuscitation Heart Function and Hemodynamics in Patients with Nontraumatic Out-of-Hospital Cardiac Arrest

Table 4

Initial potassium levels in serum were associated with the chance of survival (the median laboratory data during the first 24 hours of the postresuscitation period).

	Total patients ()	Survival to discharge ()
		Success	Failure	value
Initial K level (median) (mmol/L)	4.4	4.2	5.1	<0.001
Initial pH (median)	7.10	7.14	7.08	<0.001
Initial PaO2 level (median) (mmHg)	164.2	185.2	127.3	<0.001
Initial PaCO2 level (median) (mmHg)	58.6	49.0	62.7	<0.001
Initial creatinine clearance (median) (mL/s)	1.2	0.9	1.4	<0.001
