Inadequate humidification for tracheostomized patients can result in an assortment of adverse complications, which ultimately negatively impact the epithelial integrity of the airway. This is the case in situations where patients breathe the cold, dry air delivered by the gas supply systems of hospitals. According to the American Association for Respiratory Care (AARC) clinical practice guidelines for humidification, adequate humidification requirements when the upper airway is bypassed entails a humidity output of 33-44 mg H2O/L, with a 100% relative humidity at 34-41°C. Several types of devices may be used in the clinical setting to provide humidity therapy. Thus, awareness of the type of humidity therapy they provide is just as important as understanding their principles of operation, application, as well as their potential hazards. The use of large volume jet nebulizers (LVNs) is very common in respiratory care practice as a modality for humidification therapy. These devices are pneumatically powered, and deliver cool/bland aerosol by using a variable oxygen diluter and water passing through a jet nozzle. The aerosols provided by LVNs are usually unheated, cool and bland. Thus, one would expect to see complications arise from the wide use of LVNs in the clinical setting. However, superior efficacy of a device still remains questionable and as evident, there exists huge inadequacies in studies on humidification of spontaneously breathing tracheostomy patients and overall tracheostomy care. Heated humidifiers entail the use of active humidity, which use energy and water external to the body (e.g. a wick humidifier or passover humidifier) for conditioning inspired gases. Passive heated humidifiers on the other hand, rely on body temperature and the humidity gradient between the body and external environment. One of the most widely used types of passive humidifiers is the heat and moisture exchanger (HME), which contains a condenser element designed to enhance capturing the exhaled moisture (in the form of water vapor) from the patient's breath, then transfer and release this moisture back into the inspired air on the next breath.
