A computerized pneumatic tube specimen delivery system with system-wide air cushion soft handling features was evaluated. There were no significant differences in values (largely normal) for components of a standard chemical profile or complete blood count in specimens delivered from the outpatient center or neonatal intensive care unit by pneumatic tube compared to couriers. The pneumatic tube system also did not affect values for pO2, pCO2, and pH over a wide range (pO2, 25 to 438 mmHg) in specimens sent from the operating room during cardiac surgery. The pneumatic tube system decreased the median turnaround time for potassium and hemoglobin results on specimens from the emergency department by 25%. The system evaluated is a rapid, efficient mechanism for sending specimens to the clinical laboratory that produces no significant effects on analytical results and has the ability to decrease turnaround time.
对一个具有全系统气垫软处理功能的计算机化气动管道标本输送系统进行了评估。与快递员运送的标本相比，通过气动管道从门诊中心或新生儿重症监护病房运送的标本中，标准化学分析或全血细胞计数各成分的值（大多正常）没有显著差异。在心脏手术期间从手术室送出的标本中，气动管道系统在很宽的范围（pO2为25至438 mmHg）内也不影响pO2、pCO2和pH值。气动管道系统将急诊科标本中钾和血红蛋白结果的中位周转时间缩短了25%。所评估的系统是一种快速、高效的将标本送往临床实验室的机制，对分析结果没有显著影响，并且有能力缩短周转时间。
