• catheter
  • We have performed rapid pull-through vector manometry (8 channel catheter, 0.5 ml/min perfusion, 0.5 cm/s pull-back speed) 10 times each on 17 volunteers. (bmj.com)
  • The poor reproducibility of vector manometry has been described previously by Bemelman et al using rapid pull-through vector manometry (8 channel catheter, 0.7 ml/s pull-back speed). (bmj.com)
  • Entailing the insertion of a sensor-equipped catheter through the nose and down through the esophagus and into the stomach, esophageal manometry is performed to assess function of the organ as it moves food down into the stomach through a process called peristalsis. (pressureprofile.com)
  • sensors
  • High-resolution manometry (HRM) uses 36 sensors capable of recording pressure in asymmetrical structures, offering the spatial and temporal resolution necessary to capture pharyngeal pressure events ( 14 ). (pubmedcentralcanada.ca)
  • system
  • Rather than forcing this newer approach on healthcare providers, the manometry system was designed to accommodate those who were used to the status quo and might be resistant to change. (pressureprofile.com)
  • function
  • Symptoms were assessed at intervals of three months for 24 months by an independent observer, and the effects of sphincterotomy on sphincter function were monitored by repeat manometry after three and 24 months. (bmj.com)
  • analysis
  • We would like to raise two issues with the authors-the method of analysis used and the reproducibility of vector manometry. (bmj.com)
  • technique
  • Our own experiences with vector manometry of the LOS have shown that this technique has poor reproducibility. (bmj.com)
