Ultrasonographic assessment of diaphragm function in long-term mechanical ventilation patients

Objective To evaluate the condition of the diaphragm in patients with long-term mechanical ventilation using ultrasound technology and to analyze its relationship with ventilation time and muscle atrophy in order to clarify the reasons for diaphragm dysfunction in long-term mechanical ventilation patients.Methods Patients admitted to the respiratory department in the Chinese PLA General Hospital between June 2018 and April 2019 with mechanical ventilation were included in this study.

Utility of the type 3 portable monitor for the diagnosis of patients with obstructive sleep apnea

Med J Chin 2019;99(38):2994-99.Objective To evaluate the utility of a portable monitor at home for diagnosis of obstructive sleep apnea(OSA)in Chinese adults.Methods Eighty nine patients suspected of OSA underwent overnight,unattended home sleep apnea testing(HSAT)with a portable monitor(Nox-T3,Nox Medical Inc.Iceland)followed by an inlaboratory polysomnogram(PSG)with simultaneous portable monitor(PM)recording within one week.PSG and PM recorder were scored according to recommended guidelines by independent technicians.The correlation between PSG apnea hypopnea index(AHI)and PM respiratory disturbance index(RDI)were evaluated.Results Sleep testing showed RDI was(30.0±20.9)events/h on HSAT,and(33.4±22.4)events/h on inlaboratory PM recording.Apnea-hypopnea index(AHI)on PSG was(35.1±23.7)events/h.
