Narrative:
During pushback, APU air was insufficient to start engines. Consulted MEL while coordinating with ground crew, flight attendants, ramp control, and maintenance. Didn't discover until after takeoff that while flight crew could placard the APU, dispatcher approval is required. Contacted dispatcher who gave his approval. We should have completed MEL procedure prior to departure.
