Aspiration: Inhalation
of any foreign matter, such as food, drink, saliva,
or stomach contents (as after vomiting) into the airway
below the level of the vocal cords.
Closed Position "No Leak":
Design pertaining to the PMV. The PMV opens on inhalation
and automatically closes at the end of inhalation.
It remains closed without air leak during exhalation.
This restores a closed respiratory system and a more
normal breathing pattern to the PMV user.
Cuff Deflation: The
act of removing air from the cuff of a tracheostomy
tube.
Diaphragm: A thin, dome-shaped
muscle, important in breathing; separates stomach
and chest cavities.
Hub (15mm): The part
of the tracheostomy tube that adapts to standard respiratory
equipment, such as a ventilator.
Humidifier: A device
that provides moisture to the air we breathe.
|
Lower Airway: That portion
of the respiratory tract beginning at the larynx (voice
box) and ending at the smallest units in the lungs.
Peak Inspiratory Pressure (PIP):
A measurement of pressure in the lungs at the end
of the inspiratory phase of ventilation. It is reflected
on the airway pressure manometer of the ventilator.
Pilot Balloon: Plastic
sack-like component connected to the inflation line
and luer valve of the tracheostomy tube which allows
for inflation and deflation of the cuff.
Pulse Oximeter: Device
which measures the oxygen saturation level of arterial
blood when placed on finger, toe, or ear.
Suction: Removal of
gas or fluid (secretions) by mechanical means.
Tracheostomy: An artificial
opening in the trachea that facilitates the passage
of air and removal of secretions.
Upper Airway: That portion
of the respiratory tract beginning at the mouth and
nose and ending at the larynx (voice box).
