do you have respiratory therapists where you work? they could give you an awesome education on your machine and the alarms.

We work with drägers and we have no respiratory therapists either. Keep in mind that with the Evita line of ventilators even alarms from hours ago remain visible in the bar on top until you reset the alarms. Problems I've come across over the years is that many times you have to adjust the alarm settings on these ventilators because they are very tightly chosen by the ventilator.

When you lose your volume measurements it might be time to calibrate the flow sensor and when your oxygen levels differ too much from your settings either you're not having a reliable oxygen source with enough pressure or your oxygen cell is faulty/worn out etc. and we generally have our technicians check out when we have alarms that we can't fix and it isn't a problem on the side of the patient. In the mean time we use another machine so they have time to check it out.

As far as I know on a Dräger IPPV+autoflow is a pressure regulated volume controlled modus and IPPV equals volume control
