Last night, as I was posting pictures from a week ago, Jen was figuring out that Timmy was being super fussy because his oxygen sats. were in the 50s. Timmy's cardiologist has told us as long as it is over 70, everything is fine, so 50s was not fine. He had been struggling to breathe a little and just was plain cranky - makes perfect sense if his oxygen sats. were so low.
So, we scratch our heads, and came up with the answer quicker this time - since this has happened before. The cooler weather came in, but since it had been so hot, the humidity was very high with the cooler temps. The AC doesn't run so much when it is cooler out, and the air was more humid than normal. One of the VNA nurses brought the humidity problem up last year, and it makes sense that is what is happening again.
We upped his oxygen and he is doing better, but it appears we need to be able to dry the air when it is cooler out, so I guess it is time for a dehumidifier for the downstairs to use when it isn't hot enough for the AC to be running. In the meantime, we're hoping it warms up enough today to have the AC running more to dry out the air, windows open with 90+ percent humidity doesn't do any good for Timmy.
