Tracheostomy Humidification
The nose and mouth provide warmth, moisture and filtration for
the air we breathe. Having a tracheostomy tube, however, by-passes these
mechanisms so humidification must be provided to keep secretions thin
and to avoid mucus plugs. To keep the environment at an optimal humidity level,
follow the procedures below.
Equipment
- Air
compressor
- Nebulizer bottle
- Aerosol
tubing
- Trach mask
- Sterile
water
- Saline ampules (“bullets”)
- Heat Moisture Exchanger (HME) Also known by several other
terms including: Thermal Humidifying Filters, Swedish nose, Artificial
nose, Filter, Thermovent T.
- Room/home
humidifiers
Attach a mist collar (trach mask) with aerosol tubing over the
trach with the other end of tubing attached to the nebulizer bottle and air
compressor. Sterile water goes into the nebulizer bottle (do not overfill, note
line guide). Oxygen can also be delivered via the mist collar if needed.
Heated mist may be ordered. Heated mist is accomplished by an
electric heating rod that fits into the nebulizer bottle. Extra care should be
taken to be sure the bottle does not go dry, which could melt plastic. Many of
these heating elements do not have automatic shut-offs and this could be a
potential fire hazard. Also, more moisture will accumulate in the aerosol
tubing with heated mist. Moisture that accumulates in the aerosol tubing must
be removed frequently to prevent occlusion (blocking) of the tube and/or
accidental aspiration (inhalation). Disconnect tubing at the trach end, empty
into a container and discard. Do not drain fluid into the humidifying unit.
Fluid traps (or drainage bags) are helpful in preventing occlusion and
aspiration. These collection devices also need to be emptied frequently.
Position the air compressor and tubing lower than the patient to help prevent
aspiration from moisture in the tubing. A mist collar can also be worn during
the day when mucus is thick or blood tinged. Sterile saline drops can be
instilled into the trach tube if secretions become thick and difficult to
suction. A saline nebulizer treatment is also helpful to loosen secretions if
the patient has a nebulizer machine. Additional fluid intake also helps to keep
secretions thinner.
Secretions can be kept thin during the day by applying a Heat
Moisture Exchanger (HME) to the trach tube. An HME is a humidifying filter that
fits onto the end of the trach tube and comes in several shapes and sizes (all
styles fit over the standard trach tube opening). There are also HME’s
available for portable ventilators. Bedside ventilators have built-in
humidifiers. HME’s also help prevent small particles from entering the trach
tube. Change HME daily and as needed if soiled or wet.
