Case 6 involved a 79-year-old man with a medical history of myocardial infarction, HT, and cardiac insufficiency. He had a BMI of 20.8 kg/m2 and presented to the emergency department with spasms and sudden loss of consciousness. He was admitted to the ICU after a right middle cerebral artery (MCA) infarction was detected in his cranial diffusion MRI. He was followed-up on in the ICU for 16 days and he was tracheostomized on day 11. He performed the apnea test with the tracheostomy mask (5L/min O2) on day 15 between 00:00 and 06:00 am. The results were as follows: AHI 34/hr, AI: 3/hr, HI: 31/hr, ODI: 7hr, min. SpO2: 79%, and max HR: 97/min. It was decided that he should be scheduled to be discharged as tracheostomized, with home care conditions assured under home ventilator support (Table ).
Case 4 involved a 26-year-old man with no known medical history and a BMI of 19.5kg/m2. He was transferred to the ICU unconsciously, with a Glasgow Coma Score (GCS) score of 6 and tracheostomy due to head assault-related trauma. He stayed in the ICU for 26 days and was separated from mechanical ventilation support after 6 days. Twelve days after admission, he performed an apnea test between 00:00 and 06:00 am in the room air, which yielded the following results: AHI: 2/hr, AI: 2/hr, HI: 0/hr, ODI: 0/hr, min. SpO2 95%, and max. HR: 109/min. It was decided he should be scheduled to be discharged as tracheostomized, and with spontaneous respiration under nurse supervision (Table ).
