Question 1: chemoreceptors are regulated by?

Answer:

PaCO2,pH,CSF

Question 2: cricothyrotomy procedure

Answer:

make a 1 cm horizontal incision through the cricothyroid membrane

Question 3: Dead space volume definition? (VD)

Answer:

amount of gases in tidal volume that remains in the airway. (approximately 150 ml in adult male)

Question 4: cricothyrotomy Needle size

Answer:

14 G

Question 5: Total lung capacity definition? (TLC)

Answer:

maximum lung capacity (average male 6 liters)

Question 6: normal ranges for PaCO2?

Answer:

35-45 torr (average 40)

Question 7: O2 regulator specs

Answer:

green,chrom,white, 2:5 pin index

Question 8: Cricothyrotomy anatomical landmarks

Answer:

between the cricoid cartilage and the thyroid cartilage

Question 9: Kussmaul's respiration

Answer:

Deep,slow or rapid, gasping (common in DKA)

Question 10: Esophageal detector device test (bulb)

Answer:

• if the bulb does NOT refill then incorrect placememnt.
• if the bulb refills easilyupon release,indicates proper placement

Question 11: Difference of pediatric airways?

Answer:

• smaller jaw 2.larger tongue 3.narrowest part of the pediatric airway is cricoid cartilage
• epiglottis is rounder and floppier

Question 12: Agonal respirations

Answer:

shallow,slow,or infequent breathing (indicating brain anoxia)

Question 13: Chronic Bronchitis

Answer:

Pathophysiology: results from increased mucus-secreting cell in respiratory tee. Alveoli relatively unaffected. Decreased alveolar ventilation. Physicla exam: often overweight,RHONCHI present,JVD, ankle edema, hepatic congestion, "BLUE BLOATER"

Question 14: will a patient with PaCO2 of 30 be alkalotic or acidic?

Answer:

pt will be alkalotic thus decreasing respiratory rate

Question 15: Hering-Breuer Reflex?

Answer:

triggered to prevent over-inflation of the lungs. Pulmonary stretch receptors present in the smooth muscle of the airways respond to excessive stretching of the lung during large inspirations.

Question 16: does hyperventilation lower or raise CO2 levels?

Answer:

hyperventilation LOWERS CO2 levels due to increased respiratory rates/deeper respirations.

Question 17: Most common cause of airway obstruction?

Answer:

the tongue

Question 18: baroreceptors in carotid body regulate?

Answer:

BP

Question 19: Normal Respiratory rates? (adult,pediatric,infant)

Answer:

adult 12-20 pediatric 18-24 infant 40-60

Question 20: OPA placement

Answer:

insert with tip facing palate & rotate airway 180 degrees into position.

Question 21: Chronic Bronchitis TX

Answer:

maintain airway,position of comfort,monitor,IV,Meds (bronchodilators & corticosteroids)

Question 22: Cheyne-Stokes respirations

Answer:

Progressively deeper,faster breathing alternating gradually with shallow,slower breathing (indication brain stem injury)

Question 23: Inspiratory reserve volume definition? (IRV)

Answer:

the amount of air that can be maximally inhaled after normal inspiration

Question 24: Tidal volume definition? (TV)

Answer:

average volume of gas inhaled or exhaled in one respiration cycle (avergae adult male 500 ml)

Question 25: Airway sounds

Answer:

stridor,wheezing,rales,rhonchi,snoring,crackles

Question 26: what is the definition of VENTILATION?

Answer:

the mechanical process that moves air into and out of the lungs

Question 27: what is the definition of RESPIRATION?

Answer:

the exchange of gases between living orginisms and its environment
