Clinical Performance of the Baska MaskⓇ, the I-GelⓇ and the Self-Pressurized Air-QⓇ i

Study Overview
=================
Brief Summary
-----------------
The Baska mask (proact Medical Ltd, Northants, UK) is the latest addition to an era of supraglottic airway devices in clinical use. It is made of medical grade silicone; it has many advantages in its constructions over other LMA, a cuff less membranous bowl in which the saliva secretion collected. An inbuilt tab that allows to extend its angulation for straightforward negotiation of the oropharyngeal curve during placement

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| insertion time | To determine the time taken for insertion of the device. (It will be calculated from the time of the mask will be taken away from the patient's face till the moment of the appearance of square wave capnography upstroke with the presence of sufficient ventilation) (second ) | 1 hour | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Ease of device insertion | will be graded using a five-point scoring system (4 = insertion at first attempt without tactile resistance, 3 = insertion at first attempt with little tactile resistance, 2 = insertion at first attempt with significant tactile resistance, 1 = insertion successful at second/third attempt, 0 = insertion failed at three attempts). | 1 hours | 
| Oropharyngeal leak pressures | Oropharyngeal leak pressures (OLPs) will be recorded | 1 hours |
