When the aerosol tubing becomes disconnected from the trach mask, a caregiver may with some ingenuity attach the aerosol tubing directly to the trach guard and to the cuffed trach rather than the trach mask.If this aerosol set up has no pop off inline, the patient has no way to exhale and may develop a pneumothorax.In this case, the caregiver mistakenly was connecting aerosol tubing directly to a trach guard making a pressure-tight seal.In order to do this the connector must be inserted over the trach guard at an angle.We will add to the instructions a warning not to use the trach guard as an airway connector.It is only for use to protect an open airway from accidental occlusion.
