title: [The effects of Peking Union Medical College Hospital Critical Ultrasonic Management scheme on the etiological diagnosis of dyspnea and/or hemodynamic instability in ICU patients].
abstract: OBJECTIVE
  To investigate the effects of Peking Union Medical College Hospital (PUMCH) Critical Ultrasonic Management (PCUM) scheme on the etiological diagnosis and treatment decisions for the patients with dyspnea and/or hemodynamic instability in ICU.
  
  
  METHODS
  Patients who suffered from dyspnea and/or hemodynamic instability in PUMCH ICU were included in this study. The time to preliminary diagnosis, time to final diagnosis, diagnostic accuracy, time to accurate treatment, time to consultation with other specialties, time to other examinations were recorded.
  
  
  RESULTS
  A total of 129 patients were included in this study. In patients applied with PCUM scheme, time to preliminary diagnosis, final diagnosis and accurate treatment were (15 ± 6)min, (65 ± 16)min and (34 ± 14)min respectively, and the accuracy of diagnosis was 93.0%. PCUM patients had high sensitivity and specificity for the diagnosis of acute respiratory distress syndrome (ARDS)(sensitivity 90.2%/specificity 93.6%), distributive shock(sensitivity 92.5%/specificity 93.6%) and pulmonary edema(sensitivity 93.4%/specificity 92.7%) etc.
  
  
  CONCLUSIONS
  The PCUM scheme is associated with short time to preliminary diagnosis and high diagnostic accuracy and could improve the treatment for patients with dyspnea and/or hemodynamic instability.
