1.  ___________________ describes a secondary inflammatory response or a biological response to injury caused by energy transferred from the ventilator to the lungs.
  1. Volutrauma
  2. Barotrauma
  3. Atelectrauma
  4. Biotrauma
2.  All of the following are CORRECT about ventilator-induced lung injury (VILI), EXCEPT:
  1. Alveoli microphage with other alveoli, referred to as homogenous parenchyma disease
  2. Some alveoli will be exposed to more or less volume and pressure than others
  3. One alveolus might “distort” others as they are stretched
  4. Some are fully functional
3.  A retrospective analysis from Amato et al. (2015) found which of the following to be CORRECT?
  1. Increasing driving pressure with fixed PEEP leads to higher mortality
  2. Mortality significantly increases once driving pressure is less than 10 cm H2O
  3. Increasing PEEP with fixed driving pressure has a profound effect on mortality
  4. Decreasing PEEP leads to a decrease in driving pressure and poor survival outcomes
4.  The STRAIN in mechanical power is related to ______________.
  1. Force applied to the lungs (Driving Pressure)
  2. Response to applied stress (Distortion)
  3. Number of cycles (rate)
  4. Relationship between strain and frequency
5.  Minimizing mechanical power injury during the inspiration cycle incorporates permissive hypercarbia along which of the following?
  1. Improve compliance
  2. Redistribute Stress
  3. Reduce the number of cycles
  4. All of the above
