Influence of technique used to attach the infusion set to peristaltic finger smart-pumps on dispensing time: an experimental study

Table 3 Tukey-Kramer multiple comparisons of the time extension ratios (%) at varying dispensing rates and 3-cm traction

Dispensing rate comparison (mL/h)	Infusion set material	Pump type (%)
Dispensing rate comparison (mL/h)	Infusion set material	Pump I	Pump II	Pump III
50 vs 100	PVC	1.9 ± 0.6*	1.5 ± 0.5*	0.6 ± 0.2*
50 vs 100	PB	1.9 ± 0.6*	1.9 ± 0.6*	1.9 ± 0.6*
50 vs 200	PVC	1.4 ± 1.4*	1.3 ± 1.1*	1.0 ± 0.8*
50 vs 200	PB	1.9 ± 0.6*	1.9 ± 0.6*	1.9 ± 0.6*
100 vs 200	PVC	1.4 ± 0.8*	1.4 ± 0.7*	1.1 ± 0.3*
100 vs 200	PB	1.9 ± 0.6*	1.9 ± 0.6*	1.9 ± 0.6*

The numbers indicate increases from the average time extension ratio (%) for all infusion sets. The results of the comparison are shown in Fig. 4. *NS: Not Significant, Mean ± SD
