      <i_freetext>Intervention group: Patients are hospitalized for sleep test. Meanwhile, checklists for the Depression Questionnaire will be collected before the non-invasive ventilation and one month after the procedure. Diagnosis of depression in patients during the relevant tests is done using questionnaires and approved by a psychiatrist. Before treatment and also one month after non-invasive ventilation treatment, patients' blood gases are measured by a blood gas test. In the invasive ventilator method, the patient's breathing is supported by the CPAP device, which is connected to the patient by a mask, and helps the patient to breathe effectively. This procedure may be needed first during the patient's sleep at night and eventually with the progression of lung disease during the day. In these patients, there is a gradual improvement in daily performance and good night's sleep, and in many cases even proper weight gain occurs, so the patient gradually comes to the conclusion that he himself tends to use NIV. In this method, the pressure starts from 4 to 6 CmH2O and increases to 10 or even more if needed..</i_freetext>
