Airway Anatomy
This structure prevents food and liquid from entering the trachea during swallowing
What is the epiglottis?
The movement of air into and out of the lungs is called this.
What is ventilation?
This airway adjunct is inserted through the mouth.
What is an oropharyngeal airway?
The first priority when approaching an emergency scene is determining this.
What is scene safety?
This vital sign measures the force exerted by circulating blood against arterial walls.
What is blood pressure?
The trachea divides into these two major airways
What are the right and left mainstem bronchi?
The exchange of oxygen and carbon dioxide between alveoli and pulmonary capillaries is called this.
What is external respiration?
An OPA is contraindicated when this reflex is intact.
What is the gag reflex?
During the primary assessment, the EMT forms this overall impression immediately upon seeing the patient.
What is the general impression?
This pulse is commonly palpated at the wrist.
What is the radial pulse?
Gas exchange occurs primarily in these microscopic structures.
What are the alveoli?
A patient breathing four times per minute with shallow chest rise requires this intervention.
What is positive-pressure ventilation with a BVM?
This airway adjunct may be useful in a patient with an intact gag reflex.
What is a nasopharyngeal airway?
A patient who responds only when you apply a painful stimulus receives this AVPU classification.
What is P?
Cool, pale, clammy skin may suggest poor this.
What is perfusion?
This dome-shaped muscle is primarily responsible for normal inhalation.
What is the diaphragm?
When ventilating an adult with a pulse, each breath should be delivered only until you observe this.
What is visible chest rise?
A patient has gurgling respirations after vomiting. This should be performed before inserting an airway adjunct.
What is suctioning?
A patient with severe respiratory distress, cyanosis, and decreasing mental status should be considered this transport priority.
What is high priority/immediate transport?
A patient's pulse changes from 92 and strong to 124 and weak. This trend should concern you more than this type of measurement.
What is a single isolated vital sign?
Damage to this structure can cause upper-airway obstruction because the tongue loses muscular support.
What is the mandible?
Excessive ventilation can decrease venous return to the heart by increasing this pressure inside the chest.
What is intrathoracic pressure?
A rigid suction catheter is most appropriate for clearing this area of an adult patient's airway.
What is the oropharynx/mouth?
During a primary assessment, severe external hemorrhage should be managed at this point rather than waiting for the secondary assessment.
What is immediately/as soon as identified?
A patient has an SpO₂ of 98% but is breathing 6 times per minute with shallow respirations. The EMT should prioritize this over the apparently normal saturation.
What is ventilation?
