Yes, your CPAP, APAP or bi-level sleep apnoea machine should work in a foreign country. However, power sockets differ between countries, so make sure you pack an appropriate adapter plug. Adapters can be bought from most electronics and travel stores, as well as in airports. If you’ll be abroad for an extended period, you may wish to tell your sleep clinic that they shouldn’t expect to receive any data from your device while you are away.
