EMT chapter 10: Airway Management
Terms in this set (22)
Airway junction used in your oropharynx airway. It has two principle uses (1) To keep the tongue from blocking the upper airway, (2) to make it easier to suction the oropharynx if necessary.
is a simple technique for opening the airway in a patient without a suspected cervical spine injury.
Intrapulmonary shunting occurs when:
-the presence of pulmonary surfactant causes a decrease in alveolar surface tension, thus impairing the exchange of gases in the lungs.
-a decrease in respiratory rate and depth causes carbon dioxide accumulation in the alveoli and an overall decrease in blood oxygen levels.
-blood coming from the right side of the heart bypasses nonfunctional alveoli and returns to the left side of the heart in an unoxygenated state.
-any impairment in circulatory function causes a reduced ability for oxygen and carbon dioxide to diffuse across the alveolar-capillary membrane.
Blood coming from the right side of the heart bypasses nonfunctional alveoli and returns to the left side of the heart in an unoxygenated state.
Structures of the lower airway include all of the following, EXCEPT:
The diaphragm is innervated by the _________ nerve, which allows it to contract.
The process of exchanging oxygen and carbon dioxide between the alveoli and the blood of the capillaries is called:
-alveolar ventilation. Incorrect
All of the following are signs of hypoxia, EXCEPT:
Air moving in and out the lungs
(can be provided)
loading oxygen molecules into hemoglobin molecules in the bloodstream.
(needs to naturally occur)
exchange of oxygen and carbon dioxide.
(occurs in the alveoli and tissues of the body).
12-20 breaths per minute at rest
Indicators for a Oropharynx airway
(1) Unresponsive patients without a gag reflex
(2) Apneic patients being ventilated
patients who are no longer breathing
The introduction of foreign material into the lungs
Not enough healthy red blood cells. Hemoglobin is the protein inside red blood cells that carries oxygen. Red blood cells remove carbon dioxide by transporting it to the lungs for you to exhale.
When a patient is breathing deeply
Place a patient on their left side. They need
-to be breathing on their own
-adequate tidal volume
-they may not be injured
Airway junction used in your nasopharynx. Only to be used on
-patients with an intact gag reflex
-who is unable to maintain the airway spontaneously
-patients that are semiconscious or unconscious
