QuestionAnswer
amount of air that makes it into the alveolar airways
an decrease in alveolar ventilation with unchanged metabolism causes a ____ (increase or decrease) in blood CO2
an increase in alveolar ventilation with unchanged metabolism causes a ____ (increase or decrease) in blood CO2
defined as (tidal volume - anatomic dead space) x respiratory rate
Normal pH of the blood
main blood base
blood carbon dioxide levels (mm Hg)
blood oxygen levels (mm Hg)
calculated by taking the ratio of CO2 produced over the O2 consumed.
main blood acid
increase in respiratory rate with an increase in alveolar ventilation
Calculated by multiplying tidal volume x respiratory rate
normal tidal volume (mL)
What factor is most important in determining alveolar gas composition? (Tidal Volume or Respiratory Rate)
an increase in alveolar ventilation with unchanged metabolism causes a ____ (increase or decrease) in blood O2
QuestionAnswer
an decrease in alveolar ventilation with unchanged metabolism causes a ____ (increase or decrease) in blood O2
high blood pH
low blood pH
alveolar partial pressure of oxygen @ sea level (mm Hg)
inspired partial pressure of oxygen @ sea level (mm Hg)
T/F: An increase in respiratory rate ALWAYS increases alveolar gas exchange or alveolar ventilation.
______ partial pressure of O2 is calculated by atmospheric pressure X FIO2
_______ partial pressure of O2 is calculated by [(atmospheric pressure- water pressure) X FIO2]
atmospheric partial pressure of oxygen @ sea level (mm Hg)
ventilation _____ (increases or decreases) with an increase in pCO2
_______ partial pressure of O2 is calculated by [(inspired partial pressure of O2) - (pCO2/R)]
as you increase in altitude, what happens to barometric pressure? (increases or decreases)
defined as the volume of air held in the conducting airways during each tidal volume breath (not used for gas exchange)
amount of air that is breathed in and out each minue
increase in Respiratory rate without an increase in alveolar ventilation is known as _____.
