Table 4 Absolute and Percent change in electrolyte concentrations in PHH compared to Control

	Control (mmol/L)	PHH (mmol/L)	Absolute change (mmol/L)	Percent change (%)
Total protein	5.3	11.2	5.9	111.3
Glucose	2.9	1.3	− 1.6	-55.2
Sodium	142.3	179.9	37.6	26.4
Potassium	3.1	4.1	1	32.3
Chloride	122.4	143.3	20.9	17.1
Bicarbonate	17.3	19.8	2.5	14.5
Calcium	0.16	0.24	0.08	50.0
Magnesium	0.14	0.21	0.07	50.0
Calculated Total Osmoles	296.2	364.1	67.9
Measured Osmolality	280.8	336.5	55.7	19.8
Unaccounted Osmoles	15.4	27.6	12.2

Absolute change is the difference in concentration between the Control and PHH values. Percent change is the difference divided by the control value and multiplied by 100. Calculated total osmoles is the sum of the electrolytes, total protein, and glucose in each group (control or PHH). Measured osmolality is the mean osmolality obtained from actual measurement with VAPRO osmometer. Unaccounted osmoles represent the difference in the calculated total osmoles and the measured osmolality
