an airway (passage from nose or mouth to lungs) that is open and clear and will remain open and clear, without interference to the passage of air into and out of the body.
curtainlike fibers that line either side of the tracheal opening; not only close shut for protection but also vibrate with the passage of air to create the voice
shieldlike cartilage that protects the front of the larynx and form's the adam's apple
ting sacs that occur in grapelike bunches at the end of the airway (where gas exchange occurs on the capillaries)
that contraction of smooth muscle that lines the bronchial passages that results in a decreased internal diameter of the airway and increased resistance to air flow
severely restricted air movement in the upper airway. identified by high pitched, whistling sound when breathing. can be a foreign body or swelling of tissues in upper airway.
sound of soft tissue of the upper airway creating impedance (or partial obstruction) to the flow of air.
head-tilt, chin-lift maneuver
a means of correcting blockage of the airway by the tongue by lifting the head back and lifting the chin. ised when no trauma, or injury, is suspected.
a means of correcting blockage of the airway by moving the jaw forward without tilting the head or neck. used when trauma, or injury, is suspected to open the airway without causing further injury to the spinal chord in the neck.
a vurved device inserted through the patient's mouth into the pharynx to help maintain an open airway.
a flexible breathing tube inserted through the patient's nose into the pharynx to help maintain an open airway
vomiting or retching that results when something is placed in the back of the pharynx. this is tied to the swallow reflex.
use of a vacuum device to remove blood, vomitus, and other secretions or foreign materials from the airway.
3 rules of suctioning
1) always use appropriate infection control practices
2) suction for no longer than 10 seconds
3) place the tip or catheter where you want to suction and suction on the way out
special considerations for children
1) smaller nose and mouth
2) bigger tongue
3) narrower, flexible trachea
4) cricoid cartilage is less rigid and developed
