Validation of at-the-bedside formulae for estimating ventilator driving pressure during airway pressure release ventilation using computer simulation

Table 2 Pearson correlation coefficients indicating the strength and direction of the relationship between the actual ΔP and baseline lung compliance or baseline PF ratio for different APRV settings

	Correlation coefficient
Actual ΔP_adult vs Compliance P_high = 25 P_low = 0	0.00
Actual ΔP_adult vs Compliance P_high = 30 P_low = 0	− 0.11
Actual ΔP_adult vs Compliance P_high = 30 P_low = 5	− 0.07
Actual ΔP_adult vs PF ratio P_high = 25 P_low = 0	− 0.12
Actual ΔP_adult vs PF ratio P_high = 30 P_low = 0	− 0.19
Actual ΔP_adult vs PF ratio P_high = 30 P_low = 5	− 0.07

The correlation coefficients were found to not be statistically significant (p < 0.05)
