CPAP in the hospital, can't do without

here in aussie land, the NIV/ventilation are in ICU and some other departments. There are none on general wards, you bring and self manage your own CPAP for your sleep apnea.
Last time I was in hospital from A&E I didn't have my cpap, The best I got was o2 and they hooked me up to an alarming o2 meter.

If you have a respiratory problem needing niv/ventilation by the hospital. You would be transferred to a respiratory ward/icu and the hospital would use their ventilators and NIVs.

To this long list of users who were "allowed" to use their own xPAP machine while in hospital, I will add my most recent:
A year ago I twisted a knee while spending a week on Captiva Island on the south Gulf coast of florida. Upon return, I went into hospital when it did not respond to treatment. While there, I had a heart attack and was transferred to the cardiac ICU and subsequently to in-patient rehab. During the entire month in hospital I used my own AirSense 10 Auto with zero negative comment or concern by the nursing staff or any of the myriad specialist docs I encountered. In fact, one nurse commented that it took a load off them because I could deal with setup and tear down with each use. She also commented that they did not have a respiratory specialist assigned to the cardiac unit and would have to request and wait for one to do what I did for myself each day. The only thing they provided was distilled water each day (since I never saw a bill, I have no idea of how much they charged for it, or even if they did).
