Analysis of Fluid Balance as Predictor of Length of Assisted Mechanical Ventilation in Children Admitted to Pediatric Intensive Care Unit (PICU)

Table 4

Correlation between duration of mechanical ventilation (days) and various other variables.

Variables	Pearson correlation	Duration of mechanical ventilation	Age (yrs.)	Duration of PICU stay (days)	Fluid balance (%)	PIM2 score
Duration of mechanical ventilation (days)	Pearson’s	1.000	-0.224	0.925	0.297	0.034
	value		0.165	0.01	0.063	0.833
Age (yrs.)	Pearson’s	-0.224	1.000	-0.175	-0.302	-0.031
	value	0.165		0.280	0.059	0.852
Duration of PICU stay (days)	Pearson’s	0.925	-0.175	1.000	0.168	0.027
	value	0.01	0.280		0.299	0.869
Fluid balance (%)	Pearson’s	0.297	-0.302	0.168	1.000	0.176
	value	0.063	0.059	0.299		0.278
