I had an appointment with the Respiratory Specialist last week. Not much has changed, but we ended up having a bit of a chat about all of the extra stress my heart is under due to the state of my lungs.
I already know that my heart is enlarged and I have secondary pulmonary hypertension. During the day, if I'm sitting still, it pumps along at about 100 bpm, trying desperately to push oxygenated blood around my body. What it does at night is anyones guess!
But in the interests of finding out, there were two choices:
- Invest in an overnight recordable pulse oximeter so that I could monitor my oxygen levels and heart rate overnight
- Go to hospital for an overnight stay and monitoring
I guess you can imagine which one I chose!
So, here are the results from the first overnight study on my normal overnight oxygen flowrate - 2 litres per minute.
I have terrible trouble getting to sleep every night, so the first hour of monitoring I'm probably just lying in bed tossing and turning and still awake.
It looks like my oxygen level and my heart rate both drop once I'm asleep.
So the next step is to turn the flow rate up to 2.5 litres per minute overnight and see what effect that has.
