Enthalpy

The definition of enthalpy specifies that it is the amount of heat released or absorbed at constant pressure; how is it affected/what is it considered if pressure is variable?

Then, it would no longer be the enthalpy, it would just be the heat related or absorbed at the differing pressures. Enthaply has to be measured at a constant pressure.
