The present MDI/HME apparatus includes a valve to direct fluid flow to or away from the HME portion and to or away from the MDI portion. The present MDI/HME apparatus includes a valve arm to communicate to the caregiver whether fluid is passing through the MDI portion or the HME portion and to structurally close off an MDI port when the valve is open relative to the HME portion.
