1. A method for treating a lung condition, said method comprising:

  • implanting an air flow restrictor in an airway of the lung, wherein said restrictor allows a reduced bidirectional volumetric rate of air flow exchange between upstream of the restrictor and downstream of the restrictor through a tube that is integral to the restrictor, wherein the bidirectional volumetric rate of air flow is equal in both directions and wherein such air flow rate reduction induces at least one of controlled atelectasis and localized hypoxia in a treated region of the lung downstream of the restrictor.
