Owlet or something similar

So our baby girl was born yesterday with meconium so she’s currently in the nicu for breathing. She’s doing pretty good but I’m a bit concerned about her dropping back down once we get home. We don’t have a baby monitor yet and my husband has an HSA so we were considering buying something like the Owlet and put it on the HSA to help monitor her breathing. We asked the Nicu nurse and she was all for them just to have an extra peace of mind. So my question is, what type? I know there’s owlet, snuza, and then we saw one that is like a pad you put under their sheet that monitors. What type would you suggest?
