Cards

Term
breathing pattern associated with flail chest and respiratory alternans
Definition
paradoxic breathing
Term
breathing pattern associated with no hypoxia and diabetic acidosis
Definition
Kussmaul's
Term
breathing pattern most commonly caused by stroke
Definition
acute cerebral edema
Term
breathing pattern most commonly caused by CHF
Definition
Cheyne-Stokes
Term
alternating apnea and hyperventilation; breathing pattern?
Definition
Cheyne-Stokes
Term
how do kidneys contribute to respiratory failure?
Definition
kidney retain bicarbonate to offset the elevated PaCO2; this causes a metabolic alkalosis that inhibits ventilation
Term
endurance athletes are [more/less] sensitive to changes in ABGs
Definition
less
Term
high altitude climbers are [more/less] sensitive to changes in ABGs
Definition
more
Term
at what point does ventilation increase in response to PaO2 changes?
Definition
when PaO2 drops to 50mmHg
Term
1. diaphragm contains mostly [Golgi tendon organs/muscle spindles]
2. intercostal mm. contain mostly [Golgi tendon organs/muscle spindles]
Definition
1. diaphragm = Golgi tendon organs
2. intercostal mm. = muscle spindles
Term
location and function of PNC and APC
Definition
pons; stop inspiration
Term
location and function of DRG and VRG
Definition
medulla; DRG controls inspiration; VRG controls inspiration and expiration
Term
1. response elicited by irritant receptors
2. ...by stretch receptors
Definition
1. rapid, shallow breathing
2. Hering-Breuer reflex: stop inspiration
Term
response elicited by J receptors
Definition
rapid shallow breathing, laryngeal constriction, hypotension, bradycardia
Term
what do central chemoreceptors respond to?
Definition
changes in PaCO2 and CSF pH
Term
central chemoreceptors are more sensitive to [respiratory/metabolic] acidosis
Definition
respiratory acidosis
Term
peripheral chemoreceptors: location, function
Definition
carotid body; responds to changes in PaO2, PaCO2, and pH; effects via CN IX
Term
how do peripheral chemoreceptors respond to decrease in O2?
Definition
increase in dopamine production
Term
definition of hypopnea
Definition
decreased airflow by 30% for more than 10sec
Term
pt with hx of CHF complains of insomnia; shows reduced cognitive functions and memory loss; dx?
Definition
central sleep apnea
Term
obese pt complains of daytime sleepiness and morning headaches; physical exam shows red tonsils; dx?
Definition
obstructive sleep apnea
Term
most of sleep is [NREM/REM]
Definition
NREM (80%)
Term
diagnostic criteria for obstructive sleep apnea
Definition
polysomnographic monitoring shows >5apneas per hour of sleep that are >10sec in duration AND evidence of respiratory muscle effort
Term
treatment of obstructive sleep apnea
Definition
CPAP
