1. A method for operating at least two pumps, comprising:

  • activating a first pump using a multiple channel adjustment apparatus configured to operate with the first pump to provide nonzero fluid pressure at a first nonzero fluid pressure level; and

    transitioning from the first pump providing nonzero fluid pressure at the first nonzero fluid pressure level to a second pump providing nonzero fluid pressure at a second nonzero fluid pressure level using the multiple channel adjustment apparatus;

    wherein said transitioning comprises a gradual transitioning from the first nonzero fluid pressure level from the first pump toward the second nonzero fluid pressure level from the second pump while maintaining a relatively constant fluid pressure level within a surgical region of a patient.
