Single lumen tube has only an outer cannula, without an inner cannula

• With or without a balloon cuff at the end of the tracheostomy
• Typically used with the paediatric population
• Very uncommon in the adult patients

Cuffed Tracheostomy A low volume, high pressure tracheostomy cuff has the following functions:

• Minimises aspiration of oral/gastric contents
• Maintains an effective seal for ventilation
• Can aid in tracheostomy positioning

The cuff pressure should be checked at least 2-3 hourly using a Manometer. Pressure should be kept within the green pressure zone. To inflate the cuff or add pressure a 10ml syringe must be used.

Uncuffed Tracheostomy Tube(No Balloon) Cuffless tracheostomy tubes directives of usage:

• Never used at first insertion, except for few rare cases usually ENT cases
• It is used when tracheostomy patients are about to be weaned
• For patients who talk removal of balloon, allow airflow to upper airway
• Beneficial for patients with no issues of upper respiratory tract secretions or aspiration
