Good advice there Alsacienne
I had a general anaesthetic a couple of years ago and the recovery team just didn't have a clue
It's especially important to get back on your CPAP after the operation in case you fall asleep - yet when I told the recovery team that (I felt really drowsy at that point) they kept pointing out that it wasn't necessary as I had oxygen. I showed them how it's possible to have oxygen at the same time as CPAP - they didn't even realise that was possible
I explained that oxygen wouldn't keep my airways open. To be fair, they were really pleased at me passing on this knowledge, and a year later when I had to be re-admitted, they were 'on the ball.'
Most hospitals in the UK now insist on us staying overnight (even if the surgery we've had doesn't normally warrant it) in the High Dependency Unit so we can be observed closely. Interestingly, on one of my stays in this unit I was in a bed next to a lady who'd had a trachaeostomy for her OSA as she didn't feel she could tolerate CPAP. She was there because she had yet another nasty infection and was in a terrible state. Thank goodness for CPAP I say, as I wouldn't like her problems.
