Improvement of preoperative abnormal lung function after
individualized airway intervention
To further improve abnormal lung function to prevent airway
complications, we treated these patients with individualized atomization
intervention and tested lung function. Lung function tests showed that
the FEV1% pre values of the 45 patients were all increased up to 80%
after atomization inhalation
before surgery. Among them, the
FEV1%pre values of 27 mild patients and 4 moderate patients were
increased up to 80% after 2 days of atomization intervention, and
FEV1%pre values of the remaining 1 mild patient, 9 moderate patients
and 4 moderate-severe patients all reached 80% after 4 days of
atomization intervention (Figure 2A, B) . In addition,
we also found that the indexes of
lung function (e.g., FEV1%pre, FEV1/FVC% pre, MEF50% pre, MEF25%
pre, and MMEF% pre) in each patient with mild, moderate or
moderate-severe lung function obstruction were improved significantly
after different frequencies of atomization inhalation(Figure 2C-F) .
