In the later stages of the disease, patients become "blue pyhtelschikov".
Diagnostics
The diagnosis is based on the manifestations of the disease, respiratory function, gas composition analysis arterial blood, also analyzed cytogramme bronchoalveolar wash (UAS) to the exclusion of other diseases. Radiologically the lungs may look unchanged. X-ray examination change detected in the lungs in 50% of cases. Computed tomography reveals changes in the lungs in 90% of cases.
