  1. Why is there a difference between the set tidal volume and the volume that the patient recieves?
  2. What happens to airway pressure as the tidal volume is increased?
  3. What gas law this Volume, Pressure relationship?
  4. Why dosn't the Inspiratory and expiratory time change with the increase in tidal volume?
  5. Why does the peak flow increase with the increase in tidal volume?
