To check for the effect of two methods of providing oxygen and ventilation (named bag mask ventilation and jet ventilation) on breathing parameters of wind pipe using a monitoring technique named electrical impedance tomography during procedure for cancer-related disease of windpipe.

To evaluate the effect of two ventilatory strategies (conventional bag mask ventilation and manual jet ventilation) on peak inspiratory pressures and dynamic compliance using electrical impedance tomography after interventional rigid bronchoscopy for malignant central airway obstruction.

Design outcomes

Primary

Measure	Time frame
Peak inspiratory pressures (PIP) and dynamic Compliance (C). The recorded values will be the mean of first three readings.Timepoint: T1 and T2. T1: this is defined as time point after induction and insertion of i-gel, prior to Rigid Bronchoscopy (RB). T2: this time point is defined as the one at the end of procedure, after removal of RB and re-insertion of i-gel.	—

Secondary

Measure	Time frame
1. Regional distribution of ventilation defined as ROI in dorsal and ventral segments of both lungs 2. Respiratory Rate and minute ventilation. 3. At the end of the procedure, PulmonologistÃ¢â?¬â?¢s satisfaction score will be recorded.Timepoint: At baseline (before introduction of Rigid Bronchoscope), 0 min (immediately after introduction of RB), and every 10 minutes afterwards till the end of the procedure.	—
