ASV - Adaptive Support Ventilation Summary
Basic Set Parameters:
  1) Target MV (80-120%)
  2) PEEP
  3) FiO2
What's Happening:
 - Input height (IBW) to determine ideal minute ventilation. The vent attempts to achieve this MV w/ lowest amount of work by optimizing
  1) Pinsp (pressure with each breath)
  2) Rate, which depends on the # of breaths the patient initiates.
 - Patients can be almost completely dependent to completely spontaneous.
Best for:
 - Patients with some respiratory drive
 - Patients with no significant pulmonary pathology
 - While a "weaning" mode, it's hard to know exactly how reliant the patient is on the vent.
 - Limited control. Not ideal for patients with ARDS, COPD, asthma or other sig pulm pathology
 - Confirm the patients height and IBW are entered correctly.
 - Decreasing the % of predicted needed MV can mitigate hyperventilation but if <80% choose different mode
 - If pt apneic on SBT after being on ASV, it's like they were hyperventilated
 - No. of spontaneous breaths
 - Degree of support for delivered breaths
