Eligibility

Inclusion criteria

Inclusion criteria: All adult patients ( >18years), ASA physical status 1 to 4 scheduled to undergo surgical/ diagnostic procedure under general anaesthesia .

Exclusion criteria

Exclusion criteria: 1.Patient’s refusal to participate 2.Planned for rapid sequence induction 3.No plan to administer neuromuscular blocking drugs (NMBD) for securing airway (awake intubation, already intubated, tracheostomized patient)

Design outcomes

Primary

MeasureTime frame
To find association between clinically anticipated and actual difficult mask ventilation using capnographic grading based objective scoring systemTimepoint: Baseline, at mask ventilation without NMBD (1 minute), at mask ventilation with NMBD (2 minute)—

Secondary

MeasureTime frame
To compare the objective capnographic score before and after neuromuscular blockade, to internally validate the objective capnographic scoring system with subjective assessment of mask ventilation and to assess the choice of neuromuscular blocking drug in such scenarios.Timepoint: Baseline, at mask ventilation without NMBD (1 minute), at mask ventilation with NMBD (2 minute)—
