A method for automating physiologic alerts and derived parameters with trending heuristics includes receiving at a mobile patient monitor interface, a first input expression indicative of a first parameter source for first patient parameters from a first medical device from a user. The method further includes receiving, at the mobile patient monitor interface, a second input expression indicative of a second parameter source for second patient parameters from a second medical device from a user. The method further includes applying, at the mobile patient monitor interface, a smoothing operator to the first input expression and the second input expression. The method further includes evaluating, at the mobile patient monitor interface, a complex expression of the first patient parameters and the second patient parameters based on the smoothing operator to initiate display of at least one parameter, derived parameter, trend, or alert on a remote device.
