Case 7 involved an 8-year-old girl with a diagnosis of ventricular septal defect. She presented to the ICU as intubated after ventricular septal defect (VSD) closure. She was on 7.4mcg/kg/min dopamine, 8mcg/kg/hr dobutamine, and 0.08mcg/kg/min adrenalin support postoperatively. She received a 1mg/hr midazolam infusion for 14 hours and a 0.15mg/kg/hr tramadol infusion for 23 hours. After 24 hours, her pupils were dilated and an epidural hemorrhage and shift were detected in her cranial computational tomography (CT) scan, after which the epidural hemorrhage was extracted. Despite the lack of sedative administration for the first 96 postoperative hours, she was sedated and the conditions of her pupils did not change. A reverse flow was detected in her carotid Doppler scan but no intracerebral hemorrhage was detected in her cerebral angiogram. At 98 postoperative hours, she performed the standard apnea test and her ApneaLink™ recordings were made simultaneously. Due to the desaturation occurring at the end of the apnea test that lasted 4 minutes and 38 seconds, continuous positive airway pressure (CPAP) treatment was applied. Her PaCO2 value increased from 45 to 75mmHg and the 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.
Case 5 involved an 80-year-old man with a diagnosis of HT and DM. He had a BMI of 27.7kg/m2 and presented to the emergency department with a high sleep tendency and plegia on the left side. A right thalamic and cerebellar infarction was detected in his cranial diffusion magnetic resonance imaging (MRI) scan. He was admitted to the ICU with GCS score of 4. He was followed-up on in the ICU for 38 days and tracheostomized on day 21. The results of the apnea test conducted on day 26 between 00:00 and 06:00 am with the tracheostomy mask (5L/min O2) were as follows: AHI 18/hr, AI: 6/hr, HI: 12/hr, ODI: 3/hr, min. SpO2: 89%, and max HR: 83/min. It was decided he should be scheduled to be discharged as tracheostomized, with home care conditions assured under home ventilator support (Table ).
