AEMT AIRWAY Flashcards
once air enters the lungs, oxygen and carbon dioxide are exchanged across the respiratory membrane composed of the alveolar and pulmonary capillary walls in a process called
respiration
the exchange of oxygen and carbon dioxide between the blood and the cells of the body is called
internal respiration
T/F ventilation is controlled by the levels of carbon dioxide and O2 in the blood.
T
during swallowing a leaf shaped flap of tissue called
closes over the glottis
epiglottis
in the presence of irritation the vocal cords can spasm, closing the glottic opening. this is known as
laryngospasm
the pharynx which is in the upper airway is composed of
nasopharynx
oropharynx
laryngopharynx
where does the lower airway begin?
at the glottic opening and proceeds into the trachea
angle formed by the junction of the manubrium and the body of the sternum
angle of Louis
minute volume is
tidal volume and respiratory rate
3 upper airway problems
snoring
gurgling
stridor
partial obstruction by the tongue causing harsh, vibrating, rattling sounds
snoring
fluid in upper airway liquid, bubbling sound
gurgling
may indicate laryngeal edema, FBAO, or epiglottitis is a harsh inspiratory sound
stridor
3 lower airway problems
wheezing
crackles
rhonchi
a narrowing of bronchioles from edema or bronchoconstriction
whistling, sounds
wheezing
fluid in the alveoli
fine bubbling cracking sounds`
crackles or rales
secretions from the bronchi, coarse liquid
rhonchi
T?F the modified jaw-thrust maneuver displaces the mandible forward without hyperextending the neck
true
normal breathing rate and pattern
eupnea
increased respiratory rate caused by fever, anxiety, exercise and shock
tachypnea
gradual increases and decreases in respirations with periods of apnea
increasing intracranial pressure , brainstem injury
cheyne stokes
rapid, deep respirations with short pauses between sets
spinal meningitis, CNS, head injury
Biot’s
tachypnea or hyperpnea
renal failure metabolic acidosis, diabetic ketoacidosis
kussmaul’s
prolonged inspiratory phase with shortened expiratory phase
apneustic respirations
T/F pulse ox uses technology to assess the oxygen saturation of hemoglobin in the peripheral tissues
true
what is the measurement of carbon dioxide in exhaled air
capnometry
