My Father needed supplemental oxygen for his COPD for the last seven years of his life and I believe it extended the length and quality of those years.
I'm always happy when I see someone that is out and about with their oxygen tank because they're able to enjoy some time outside of their home because of using it, and I think they should be encouraged to do as much as they can.
My Father used an oxygen concentrator and it could be transported easily, even though it was about the size of a large console style dehumidifier. Hopefully, they've had a chance to make them smaller and lighter since 1990.
If your Father will need oxygen, I'm sure it'll require the formality of a Prescription from his Doctor. I was curious about the size of the oxygen concentrators since 1990 and I did a search on the Internet for them. I found a Website at Healthtology.com that has lots of info about traveling with portable oxygen and they have a link about providing oxygen for cruise ship passengers, and I thought, how appropriate! Here's the link:
Oxygen for Vacation Travel I'm sure there are many others that would also supply it, but I though it would be good for information at least.
I would also suggest that you contact
DCL either directly or through your
Travel Agent and ask for the Medical Needs Form. By filling it out, you inform them of your medical needs so that can be aware of them and also prepare for them, if necessary. I fill out the form because I have Obstructive Sleep Apnea and will bring my own equipment and I also need to adhere to the same diet that a diabetic needs.
I'm sure your Dad will enjoy the cruise!
