Subglottic Suctioning Inner Cannula
The inner cannula has a suction catheter attached to the outside. This allows it to removes secretions (accumulated above the cuff) through the fenestration of the Blom Fenestrated Cuffed Tracheostomy Tube. It can be used at a continuous suction of 20-30mmHg or an intermittent cycled suction at 100-150mmHg. The suction line cap allows for intermittent manual suctioning when needed.
This cannula comes in 4 sizes and the suction cap is color coordinated:
Size 4= Grey
Size 6= Green
Size 8= Blue
Size 10= Black
