I hear ya! Our pulm and cardio did not want her having any surgerys right now. Her adnoids, tonsils, and uvula are all large…but a nasal spray everyday is helping enough for now. Shes on meds for reflux and adtrovent to hopfully help with the tracheomalacia plus pro-air, albuteral, and a ocapella device. Ist helping some. So i hope the next sleep study is better…just the low heart rate:) 38-45 at night:( scares me to put her to bed! I check on her all night! 55-60 is her resting hr. During day.we also put a ionizer in her room…its the freshest room in the house! Better be for the price! And sleeping on a incline. Did yours say anything about varying qrs?
