Commodity----ASV

  It seems the most desired piece of equipment today is the Mechanical Ventilator, for Adaptive Support Ventilation, the Breathing Machine. But would  everyone want one, even if they were medically eligible and the machines were available. 
   Several years ago, I was contemplating knee replacement surgery. I researched extensively on youtube and hospital surgical sites. I viewed dozens of TKR's performed on models, cadavers and living patients. I felt encouraged and informed enough to proceed with both surgeries, with complete success.
  Not that I'm contemplating the use of a ventilator, but curiosity as to how they functioned led me to check once more with youtube.
   Right away, with the insertion of the breathing tube the first line of  defense, I thought I'd seen enough to say I'd pass my potential ventilator on to then next patient in line. But then, I do believe that a breathing tube is inserted during TKR's also. But the videos focus on the sawing and cutting of bones, tendons and patellas and such, so the patient is unaware of other invasions.
