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