7. My tracheostomy tube does not have a 15mm hub to attach the PMV. What do I do?

Plastic Tracheostomy Tube - If you have a plastic tracheostomy tube, make sure that the inner cannula is in place. There are some plastic tubes that must have the inner cannula in place in order to have a 15mm hub. Some plastic tracheostomy tubes come in a low-profile model. If you have a low-profile model, it usually comes with a second inner cannula that has a 15mm hub. Remove the low-profile inner cannula and replace it with the inner cannula that has the 15mm hub.

Metal Trachestomy Tube - If you have a Pilling Weck Improved or Premier Medical metal tube in a size 4, 5, or 6, the PMV 2020 Tracheostomy Speaking Valve with PMA 2020-S adapter can be used. This Pilling Weck tube is unique from the original metal tubes because it has a small hub (about 1/2 cm) that is attached to the inner cannula.

If the metal tracheostomy tube you have is not a Pilling Weck Improved or Premier Medical in a size 4-6, then an endotracheal tube (ETT) adapter sized to fit your tracheostomy tube can be used to create a 15mm hub. Once the 15mm hub is in place you need to place a PMV other than the PMV 2020. Below is a list of reasons why you would need to utilize an ETT adapter:

• You have an original metal tracheostomy tube (the inner cannula is flush with the neckline).
• You have an improved metal tracheostomy tube in a size larger than 6.
• You have an improved metal tracheostomy tube, but it is not a Premier Medical or Pilling Weck brand tube.
