Upper Airway Anatomy
This is the scientific name for the voicebox
The larynx
The structure in which gas exchange occurs
The alveoli
The primary function of the respiratory system
To provide the body with oxygen and eliminate carbon dioxide
Respiratory disorder that is usually caused by a sensitivity to an allergen
Asthma
When would you use a BVM and when would you use a non rebreather mask on a patient?
Use a non rebreather when the patient is breathing independently, but their oxygen saturation is lower than normal. Use a BVM when the patient is not breathing or whose breathing is too slow or shallow
This structure is immediately posterior to the trachea
The esophagus
The reason the left lung is smaller than the right lung
To make room for the heart
What stimulates the medulla and what it does when it’s stimulated
An increase in carbon dioxide stimulates the medulla to initiate the ventilation cycle
Condition in which the body’s cells don’t receive enough oxygen
Hypoxia
Can an EMT administer an MDI
They can assist the patient in administering one if the patient already has one
The thin, leaf shaped flap that prevents food and liquid from entering the trachea
The epiglottis
The lobe that is present in the right lung and not the left lung
The middle lobe
The difference between respiration and ventilation
Ventilation is the movement of air in and out of the lungs and respiratory is the exchange of oxygen and carbon dioxide in the alveoli and tissues
Inflammation of the membrane lining the lungs
What should you do if you find a patient who is not breathing but has a pulse
Open the airway via jaw thrust or head tilt chin lift and check for obstructions
Name the three structures of the pharynx
The nasopharynx, oropharynx, and the laryngopharynx
Lower airway pathway
Trachea, Bronchi, Bronchioles, Alveoli
What pH does carbon dioxide level affect?
The pH of the cerebral spinal fluid
The noninfectious, chronic respiratory infection that occurs when the walls of the alveoli deteriorate and lose their elasticity
Emphysema
The cure for an upper respiratory infection
There is no cure for infections
Name all the structures of the upper airway
Nasopharynx, Nasal air passage, Pharynx, Oropharynx, Mouth, Epiglottis, Larynx
Location of the crichothyroid
Between the thyroid cartilage and cricho cartilage
Hypoxic drive function
The back up system that controls respirations when stimulated by low oxygen levels
Inflammation of the nasal mucous membrane
Rhinitis
What do you do for a patient with agonal gasps
You must use a BVM and you should check for cardiac arrest because atonal gasps are a sign the heart has stopped
