Interventional Bronchoscopy Under Noninvasive Ventilation

Interventional Bronchoscopy Under Noninvasive Ventilation for Central Airway Stenosis

To evaluate the effect and safety of noninvasive ventilation assisted interventional bronchoscopy for hypoxemia patients with central airway stenosis.

With the sedation and analgesia, noninvasive ventilation assisted interventional bronchoscopy for hypoxemia patients with central airway stenosis is safe and effective, carries high satisfaction rate.

Inclusion Criteria:

• (a)patients with central airway stenosis need interventional bronchoscopy. (b) partial pressure of arterial oxygen (PaO2)/fraction of inspired oxygen (FiO2) ratio less than 300;

Exclusion Criteria:

• (a) facial deformity sufficient to preclude mask fitting; (b) upper gastrointestinal bleeding; (c) upper airway obstruction; (d) acute coronary syndromes; (e) tracheostomy or endotracheal intubation(ETI) before admission; (f) need for urgent ETI due to cardiac or respiratory arrest.
