When you can’t breathe in your sleep and almost suffocate, the first thing to do like this is to go to the hospital first to rule out if it’s apnea syndrome. If breathlessness is present during the day and there is panic, chest tightness and breathlessness, it may be necessary to rule out a physical problem in addition to panic disorder if the heart and lung tests are fine. Depending on the disorder, the treatment is different: if panic disorder is considered, antidepressant treatment is required. If it’s apnea syndrome, look for the cause, whether it’s an ENT problem or primary apnea syndrome. If it is primary, you need to sleep with a respirator to avoid a prolonged state of lack of oxygen in the brain, which can cause accidents. So the treatment for sleep apnea is different depending on its disease.
