AIRWAY UNIT EXAM EMT 110/111 UPDATED ACTUAL
QUESTIONS AND CORRECT ANSWERS
Question:
1. Upper airway
Answer:
Pharynx, Mouth, Epiglottis, and Larynx
Question:
2. lower airway
Answer:
trachea, bronchi, bronchioles, alveoli
Question:
3. Ventilation
Answer:
the process of moving air in and out of the lungs to facilitate gas exchange
Question:
4. Respiration
Answer:
The exchange of O2 and CO2 in the lungs.
Question:
5. Central respiratory control mechanism
Answer:
the neural system located primarily in the medulla oblongata and pons of the
brainstem that regulates the rhythm and depth of breathing by responding to
changes in blood carbon dioxide levels, oxygen levels, and pH,
Question:
6. Peripheral respiratory control mechanism
Answer:
the system where specialized sensory receptors, called "peripheral
chemoreceptors," located in the carotid bodies and aortic arch, monitor changes
in blood oxygen and carbon dioxide levels, sending signals to the brain to adjust
breathing rate and depth in response to fluctuations in these gases, essentially
maintaining proper gas exchange in the body
, Question:
7. Hypercapnia
Answer:
increased CO2 in blood
Question:
8. hypoxic drive
Answer:
A "backup system" to control respiration; senses drops in the oxygen level in the
blood.
Question:
9. COPD
Answer:
chronic obstructive pulmonary disease
Question:
10. pulse oximetry
Answer:
An assessment tool that measures oxygen saturation of hemoglobin in the
capillary beds.
Question:
11. Alpha & Beta receptors
Answer:
receptors in the blood vessels that help the bodies fight o flight response
Question:
12. respritory distress
Answer:
refers to breathing that becomes difficult or labored
Question:
13. respiratory arrest
Answer:
stops breathing
Question:
14. Cheyne-Stokes respiration
Answer:
Irregular respiration followed by a short period of apnea
