Anyhow it ends up as a note in your PNR, you can take a bag along with the CPAP (it would be virtually impossible to avoid that) and if challenged at the gate they can read the notes. I would still take a medical letter identifying your name against the CPAP, you probably have something already. The reason being that due to the healthcare economics of the USA, CPAP are much more common in the USA than in Europe / Portugal, where we would normally prescribe other pathways apart from CPAP as much as possible. So it's rare for these to show up at a gate outside the USA, and a doctor's letter or similar may help.
