Could someone who knows please explain what the difference is.
And how a ventilator works...is the patient anaesthetised as they are when intubated? Or is it as I imagine just oxygen being pushed through at a greater rate than the usual oxygen mask but requiring more complicated monitoring.
Thank you.

theres different types.
some are done via a mask (cpap)continuous poitive airway pressure which i much like your econd example, and some are done with a tube while patient are anathematised. Some are done via a tracheostomy (so no tube)
anaesthetised of course
When a person breathes normally, air is drawn into the lungs by the negative pressure formed by the expansion of the ribcage and flattening of the diaphragm. In a ventilated patient, the air is pushed in via positive pressure. The patient is normally given anaesthetic agents when an intubation tube is inserted, how long sedative agents are continued depends on how the patient is weaning. The general principle is to use minimal sedation to keep the patient comfortable. When a patient is weaning there may well be period when no sedation is used at all ( we have had patients up and walking whilst still ventilator dependent).

Oops, just noticed these answers.
Thank you both, a bit clearer now as to how they both work.
