hi guysi just have a quick question about tracheostomy care. if a patient have a disposable inner cannula, do you guys change it once a day or when you are doing a trach care do you wash inside inner cannula but place it back after washing it? how often do you change the inner cannula? what is considered trach care? does anybody have like any nursing journal about how often inner cannula needs to be changed or what needs to be done?
