But how do you know what size catheter to use? Take a look at our guide to figuring out French sizes for urinary catheters. Catheter Sizes: French Catheter Sizing All internal urinary catheters, including Foley catheters and intermittent catheters, are sized by a universal gauge system. This...
The purpose of the study is to quantify the variation in the metric equivalent of French size in a range of medical devices, from various manufacturers, used in interventional radiology.The labelling of a range of catheters, introducers, drains, balloons, stents, and endografts was examined. ...
Furthermore, the current catheter sizing using the "French" measurement of outer diameter is unhelpful; it does not reflect the internal diameter and gives no information on flow rate. To illustrate this and to improve catheter selection, notably for chest drainage, we assessed the variation of ...
