The maximal static Inspiratory and Expiratory Pressure measurements ([PI.sub.max] and [PE.sub.max]; cm [H.sub.2]O) were obtained by a Pocket-Spiro Mouth Pressure Monitor with a differential pressure transducer (MPM100; Medical Electronic Construction[R]).
Maximum inspiratory pressure and maximum expiratory pressure (MEP) are simple, convenient, and noninvasive indices of RM strength at the mouth (12).
Before the operations, respiratory function test, maximum expiratory pressure, maximum inspiratory pressure and arterial blood gas assessment tests were done and recorded as T0.

MEDICAL SCIENCE SUPPORTS RESPIRATORY TECHNOLOGY AEROSURE's mode of action is based on two well-established systems; these are inspiratory muscle training (IMT) effects and oscillatory positive expiratory pressure (OPEP).
We suggest that in our patient cough may have increased positive expiratory pressure leading to rupture of endobronchial cartilage and subsequent lobar collapse.
The high frequency jet ventilation generates an expiratory plateau pressure creating a positive end expiratory pressure responsible for the oxygenation through diffusion mechanisms.
