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 8 involved a 42-year-old man with a diagnosis of hypertension who presented to the ICU unconscious and after a 20-minute resuscitation. His pupils were with fixed and dilated, his GCS score was 3, he was orally intubated, and had hypotension following a loss of consciousness and cardiac arrest. After detecting a subarachnoid hemorrhage in his cranial CT scan, he was started on anti-edema therapy and sedative medication. The cerebral angiogram performed twelve hours after admission to the ICU showed that there was no cerebral hemorrhage, and so a standard apnea test was performed with ApneaLink™ recording the apnea data. After nine minutes, his PaCO2 value increased from 41 to 76mmhg and ApneaLink™ showed that there was no respiratory effort present. This demonstrated that the presence of apnea can be seen and recorded by ApneaLink™ during the apnea test.\nAll patients were Caucasian.
