This course is an updated version of Alternative Ventilator Humidity: When and How (V7190).
Expiration Date: October 28, 2018
This course is designed for respiratory care practitioners working with mechanical ventilators and focuses on the indications, rationale, and application of alternative humidification methodology in ventilator management. The differences between traditional hot water-bath (active) and the alternative (passive) heat-moisture exchangers (HMEs) and the application of each of these humidification methods during mechanical ventilation are discussed.
- List three general complications that arise secondary to inadequate humidification of the lower airway during mechanical ventilation.
- Name the minimum amount of water molecules in milligrams that need to be provided by either an active or passive humidifier.
- Name two methods of providing humidity therapy during mechanical ventilation.
- List three reasons for promoting the clinical use of alternative (passive) humidification.
- List the sequence of correct attachments when introducing a small-volume nebulizer (NEB) or metered-dose inhaler (MDI) to the ventilator circuit using a passive humidifier.
- Describe secretion viscosity scoring developed by Dr. Suzukawa and colleagues and the rationale for this assessment method.
- Describe flex tubing condensate scoring developed by Dr. Beydon and colleagues and the rationale for this assessment method.
- Identify the alarm parameter on the mechanical ventilator that alerts the clinician to replace the heat and moisture exchanger filter (HMEF; passive humidifier) with a new unit.
- Outline the protocol that helps providers select the appropriate method (passive versus active) of providing humidity during mechanical ventilation.
- Explain why passive humidification should not exceed 4 days while a patient receives mechanical ventilation.
- Recognize when to replace an HMEF.
