Confirm the position of the LMA by auscultating bilateral breath sounds and an absence of sounds over the epigastrium, observing chest rise with ventilation, and placing an ET CO2 to look for color change.

Ensure that the vertical black line on the tube is at the patient’s midline.

Assess for ability to generate up to 20 cm of water pressure without a leak.
