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