The dial has two zones of measurement graded in cm H2O with colour coding for optimum visibility. The Luer connection allows the gauge to be connected to laryngeal masks or intubation tubes, either directly or via the connecting tube. The Ambu Cuff Pressure Gauge has an ergonomic design and is easy to operate thanks to the integrated inflation bulb and release valve. It addresses the particular needs of anaesthesia and resusitation services.
