25 F, slim (152cm, 41.5kg). Cardiologist ordered a-home sleep screening study because of fatigue and shortness of breath during the day. Told me I have mild sleep apnea (5.9 episodes per hour) but was more surprised at the fact that my O2 levels went down to 75 at one point. I’m having an official sleep study done in two weeks but I’m very concerned and feel like I shouldn’t be waiting that long. Any advice/tips would be greatly appreciated..
