'It stops me being hospitalized'

(CNN) -- Marcella Creedon, 20, from Cork in Ireland has cystic fibrosis. She has software loaded on her mobile phone that allows doctors to keep track of her condition remotely.
When I first heard about the concept of software being installed in mobile phones, which would enable doctors to monitor my cystic fibrosis, it was unlike anything I'd heard before. It certainly is a novel idea.
Every night before I go to bed, I blow into a peak flow meter that measures my lung capacity.
The peak flow meter is connected to my phone -- a bit like you connect headphones to a cell phone to listen to the radio.
There's software on my phone that measures my breath and then asks me a few basic questions about how breathless I am feeling and how I am feeling in general.
The data is then sent off to a server where my doctors analyzes it. It's really simple to use -- you don't have to be a computer whiz and I've been using the device for nearly a year. It takes you through everything really simply, step by step.
If there's a problem, they call me up and check to see how I'm feeling. The first time they rang and asked how I was feeling. I told them not to worry because I was feeling fine. The next day I was practically dying in hospital with a really bad chest infection.
Now when they phone me, I believe them that something's wrong. I've lived with this illness for 20 years. I thought I knew it really well, but now I know that this technology has a better handle on it than me.
I am the type of person who, when I feel just a little bit ill, I keep on going. But this software makes me take notice of my symptoms more.
Basically, it can be the difference between spending two weeks in hospital on an IV drip and having major scar tissue damage to my lungs, to having two weeks on oral antibiotics. It's also a huge saving to the country -- time not spent in hospital saves a lot of money.
I am studying veterinary nursing in Bristol, in south west England, and when I go back home to Cork in Ireland during the holidays my doctors can keep track of my condition while I'm away.
It's nice to have that peace of mind that my doctors are looking after me -- they're a really dedicated bunch who notice the tiniest of changes to my condition. It's amazing.
