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.

Course Objectives

  • 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.

Traci Marin, PhD, MPH, RRT, RPGST, is an assistant research professor, program director, and professor for the Department of Cardiopulmonary Sciences, Schools of Allied Health and Medicine, at Loma Linda University. She is also an adjunct researcher and advisor at the Department of Medicine, at Dr. John Shyy’s laboratory at the University of California, San Diego, as well as the founder of Tranquility Community Health. Dr. Marin received a PhD from the University of California, Riverside, in biochemistry and molecular biology; an MPH in epidemiology and biostatistics from Loma Linda University; a bachelor’s degree in emergency medical care from Loma Linda University; and an associate’s degree in respiratory therapy from Victor Valley College.

Brian Parker, MPH, RRT, has been a practicing respiratory therapist since 1964. His background includes clinical assignments in routine care and critical care, as well as in education, management, and marketing. His clinical assignments have included patients at high risk (organ transplant, burns, trauma) requiring strict adherence to infection control principles. Brian’s clinical education assignments included departmental management responsibilities for infection control and quality assurance at a large university-affiliated medical center. Additionally, he has held faculty posts with numerous respiratory care programs, where he was responsible for the didactic presentation of evolving infection control methods, along with clinical presentation and evaluation of student implementation of those methods. He has taught respiratory care courses for 15 years. Brian has also conducted laboratory exercises for respiratory care students annually in preparation for their introduction to clinical experience. His education has included graduate-level course work in epidemiology, statistics, and microbiology that all contribute to content knowledge and have enriched his practice knowledge in professional respiratory care.
