When the new Erie County Medical Center (Buffalo, NY) was built, a pneumatic tube network, manufactured by Mosler Airmatic and Electronic Systems Company, was installed. This network, called the Mosler System 4000, was designed to handle 600 transactions per hour in the hospital, and therefore had to have a high carrier speed (8m/sec). When blood specimens were sent through the system, blood cells were slightly damaged and lactic dehydrogenase activity in the serum was consistently elevated. But neither acidic phosphatase, potassium, blood gases nor urinary casts were significantly affected by tube transport.
当新的伊利县医疗中心（纽约州布法罗市）建成时，安装了由莫斯勒气动与电子系统公司制造的气动管道网络。这个网络被称为莫斯勒4000系统，设计用于处理医院每小时600笔业务，因此必须具备较高的载体速度（8米/秒）。当血液标本通过该系统传送时，血细胞会受到轻微损伤，血清中的乳酸脱氢酶活性会持续升高。但酸性磷酸酶、钾、血气或尿沉渣均未受到管道运输的显著影响。
