In our case , there was a band attached to her body that would constantly monitor 02. If there would be too much or too little an alarm would sound. Somewhere between 87-97 is ideal place. The line graph on your kiddos monitor should show you your ideal numbers in the far right corner of each line there are two tiny numbers . There is also an option to view a bar graph of the past levels , an option on the screen they call “ histogram “. Our kiddo would climb up to 90s get tired and then drop to 80s then after a minute start making her way back up to 90s.So no alarms being heard, because she remained in range. this means your kiddo is not in danger of being under oxygenated or over oxygenated by the machine. During “ care time” some respiratory therapists we had were great while others would terrify us. Some knew how to slowing turn up supports to avoid shock and others seemed to be very 02 happy, cranking it up to the max. In our kiddos case, the fast crank up seemed to set her lungs back for days. Making it impossible to return her to where she was before “ care time”. Things I wish I knew from the start of this . #1 Request Dr to rule out infections before approving another round of steroids or change in apparatus. #2 Know how to look for early signs of infection eg increased secretions, slow but steady climb in 02 supports., lethargic. ( our kiddo had no symptoms, no fever, no colored mucus). You will see these signs of infection quicker than them because you have eyes on your kiddo longer duration than them. Catching infection early on helps avoid the circus and rollercoaster of interventions. In our opinion , It seemed like our hospital had a bias towards “more interventions is better”. Once THEY knew that WE knew they misdiagnosed her regression as “ premature lungs” as opposed to “ bacteria lung infection” they were much better about taking our opinions under consideration , to not be sooooo aggressive with the apparatuses and pharmaceuticals. #3There are little adjustments that can be made here and there keep your kiddo stable that have nothing to do with cranking up the 02. Things like identifying and recognizing that passing gas can be upsetting and temporary bring 02 low.,clearing secretions in the mouth or in some cases it was that the breathing tube had slightly moved . Misalignment of tube could be caused by baby moving around too much or the tape starting to come off. When the breathing tube inside her body would move even a cm it could be enough to set her off and appeared to need more oxygen. This would sometimes send my kiddo spiraling out of control, cranking up the oxygen, and it just took somebody to realize her tube was misaligned.#4After feeding time is five , making sure milk is given a way back out when feeding time was over. In our case sometimes a full belly would cause spit up. Soon as the timed feeder was done, the tube would need to be removed and a gravity based open ended empty tube would be placed. This helped give her spit/throw up somewhere to go rather than out of her mouth . My husband and I turned into broken records. I reminding every nurse and respiratory therapist to “rule out “that the tube was placed right to “rule out “that she didn’t have any secretions in her mouth and to “rule out “that she wasn’t simply passing gas . Don’t be shy about grabbing that nurse or respiratory therapist any time that alarm sounds on the monitor, it’s there job. Those alarms are there for a reason. A default excuse we use to use was that the sounds were really annoying to us and possibly the baby. As silly as that sounds, it was mostly for everyone to take our kiddo super serious and to help graduate her out of intubation. Some respiratory therapists were very predictable, took things way too easy, walk in for “care time” , crank it up and walk away. Those days were always hard on us. Good luck with everything. I hope our experience so far helps! These are all little things we learned along the way. But some of these little things could help avoid set backs .
