*7.3.3 The LMA Guardian™ (GLMA)*

The Guardian laryngeal mask airway™ (GLMA) (Teleflex®, USA) is a new disposable silicone SGA device. The cuff forms a seal with the glottis for ventilation, and with the hypopharynx for airway protection. The gastric drainage port helps to suction the stomach contents. Also, it has a port for suctioning material from the hypopharynx. The pilot balloon valve with pressure logo indicates visual intracuff pressure (Yellow <40 cmH2O, Green 40–60 cmH2O and Red >60 cmH2O) (**Figure 10**). A study suggests that it provides sealing pressures as high as 32 cm H2O [72, 73].
