Rebuttal to APC a False Sense of Security

In a previous post "Adaptive Pressure Control Ventilation during Anesthesia: a False Sense of Security", I argue that the anesthesia provider should use this mode with caution and described how the mode reacts during changes in pulmonary mechanics. 

After reading the post one could assume that I'm against using this mode of ventilation.

However, I believe this mode has many advantages.

Flu season not for me!: Surveillance screening for scheduling.

So what are the optimal times to be at work versus being on vacation, in regards to working smarter?

Dr. Ben Goldacre presents the topic of research misconduct in medicine and how unreported negative trials may mislead practitioners to the actual safety of a pharmaceutical agent.

In a previous post "Determinants and Limits or the Draeger Narkomed Anesthesia Machine in Regards to Ventilating the Morbidly Obese Patient", I tried to calculate the largest patient a bellows system could ventilate safely. 

I concluded that if you wanted to deliver a minute ventilation greater than 9 liters per minute, using conventional ventilator settings (tidal volume of 10 ml/kg/IDBW) that the operator would run into issues.
