An online continuing education course for nurses, medical health care professionals, and other interested individuals.

The aging of America’s population combined with new extended life expectancies is resulting in an unprecedented demand for long-term care. This course is designed for nursing and other departments who have ventilator patients in their every day environment.

These ventilator patients may be located in hospital ICUs, Long Term Acute Care Hospitals (LTACH), Skilled Nursing Facility (SNF) and in-home ventilator patients across the country.

The Science of HMEs program will answer many questions regarding heat and moisture exchangers HMEs, which are also known as passive humidifiers.  We will explain what can be expected with different types of heat and moisture exchangers and why many heat and moisture exchangers will not work on all patients. 

Staying current in evidence based practice and education is important. This information is essential when understanding Respiratory Care and the humidification of the ventilated patient.


  1. Define the basic concepts of humidity and the differences between Absolute Humidity, Relative Humidity, Specific Humidity and Dew Point.
  2. Describe the body’s natural humidification process.
  3. Recognize the clinical uses for molecular water and conditions requiring humidification.
  4. List the American Association of Respiratory Care Clinical Practical Guidelines for humidifying patients when the natural humidification process is bypassed.
  5. Describe the differences between Active Humidification and Passive Humidification.
  6. Humidification of patients with Passive Humidifiers.
  • Define the definition of the artificial nose
  • Identify how passive humidifiers function
  • List the 6 different types of passive humidifiers
  • Recognize why the design of passive humidifiers is important
  • Name the different types of humidification media

  • List  important features of passive humidifiers
  • Demonstrate documentation of passive humidifier effectiveness
  • Describe what to look for when using a passive humidifier
  • Identify the procedure of humidifying patients with tracheostomy (Trach) tube
