Hi I'm looking for some advice I'm currently caring for my 82 year old mother who has secondary breast cancer she's been suffering with breathlessness for a while and uses a fan to help she also takes oramorph although this only helps A  little she has an appointment with a respiratory nurse soon but the weather recently has been making it worse and she's struggling I'm not sure if this is an appropriate place to ask but I just want some independent advice I've been looking into portable air conditioning units and am just getting a little overwhelmed as they all seem to have mixed reviews and it's a lot of money to spend on something that might not work so I'd just like to ask if anyone can recommend one or give any advice on how to keep a room cool or things that could help with her breathing I appreciate any advice anybody could give thank you.
