Regarding Work of breathing Pressure volume curves

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

1At the apex of the lung
1. AIncrease in RV
2. BIncrease in FRC
3. CComplaince is increased
4. DVC is decreased
5. Eall of the above are correct
2Airflow will go the area of highest compliance First so it will go to the apex
1. AVerdadero
2. BFalso
3Relative ventilation is highest at the base of the upright lung due to the base having higher compliance at FRC than the apex
1. AVerdadero
2. BFalso
4Work of breathing involves elastic (35%) and viscous resistance (65%)
1. AVerdadero
2. BFalso
