Summary Syringe pumps are almost universally used for constant perfusion oesophageal manometry, despite important technical limitations. A pneumatically driven perfusion pump has been designed specifically for oesophageal manometry. This pump requires less than one third the flow setting of a syringe pump to achieve a given rate of pressure rise. It is simple to operate and needs infrequent refilling. Nearly two years' practical experience with this pump has confirmed its superiority over the syringe pump for constant perfusion manometry.
