You can not use the cannula in the follow up study after 3 months of treatment. Ask the participant to bring their own mask and tube from the pap machine.
To measure the flow in the mask please use a green hose and a connector – see pictures below. This is not included in the consumables from Nox Medical, you need to buy the green hose but one connector (to reuse) will be handed out to each center at the General Assembly.
You open a new bag of cannula (included in consumables from Nox Medical) and loosen up the filter and use this filter to connect the green hose to the A1s.
Then you fit the other end of the green hose to the connector and link between the mask and the tube that connects to the PAP machine.
Configure as usual but only for one night.
