Gravity effects on lung and work of breathing

Gravity effects on lung and work of breathing

Question 1 of 5

1

At the apex of the lung

Select one of the following:

  • Increase in RV

  • Increase in FRC

  • Complaince is increased

  • VC is decreased

  • all of the above are correct

Explanation

Question 2 of 5

1

Airflow will go the area of highest compliance First so it will go to the apex

Select one of the following:

  • True
  • False

Explanation

Question 3 of 5

1

Relative ventilation is highest at the base of the upright lung due to the base having higher compliance at FRC than the apex

Select one of the following:

  • True
  • False

Explanation

Question 4 of 5

1

Work of breathing involves elastic (35%) and viscous resistance (65%)

Select one of the following:

  • True
  • False

Explanation

Question 5 of 5

1

Regarding Work of breathing Pressure volume curves

Select one of the following:

  • Restrictive disease elastic work increases

  • Obstructive disease - viscous work increases

  • In patients with increased lung compliance (emphysema) slow deep breaths would minimize the work of breathing

  • all of the above are correct

  • None of the above are correct
