Bedside scoring tool to determine RTX-responsiveness 4 hours after initiation of therapy in children with acute respiratory failure

Input:
Does the patient have etiologies(Dx)?
FiO2 setting on RTX at 8 hours (Range:0.21~1):
Negative pressure setting on RTX at 4 hours (please enter as a negative number)(Range:-24~-8):
Positive pressure setting on RTX at 4 hours (leave blank if on CNEP):(Range:0-8)
Is the patient on any form of non-invasive positive pressure ventilation?

Result:

Predicted Score and  Confidence Limits for Predicted Score:

The score is calculated as exp(lp)/(1+exp(lp)) where lp = 7.5235-0.6047 * Dx -2.3652 * FiO2+ 0.2420 * RS4NEG +0.3924 * RS4POS -2.5693 * NIPPV.

Please contact Dr. Amanda Hassinger at the University at Buffalo, State University of New York, for more information or if you would like to contribute raw data to further refine the calculator.
