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