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