Catheter Sizes: French Catheter Sizing All internal urinary catheters, including Foley catheters and intermittent catheters, are sized by a universal gauge system. This gauge system is known as a French size, which is based upon a measurement of the external diameter of the catheter tube. The ...
Products were chosen to achieve a broad range of French sizes from several manufacturers. To assess manufacturing accuracy, eight devices were selected for measurement using a laser micrometer. The external diameters of three specimens of each device were measured at centimeter intervals along the ...

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 ...
Measurement of intima-media thickness is useful in detecting vascular inflammation. Simplified cut-off values have been defined: 0.4 mm for the whole face, 0.7 mm for the vertebral arteries, and 1 mm for the axillary and common carotid arteries [20]. The lack of sensitivity and specificity of...
He gave his name to the savart, a unit of measurement for musical intervals, and to Savart's wheel—a device he used while investigating the range of human hearing. Birthplace: Charleville-Mézières, France Albert Calmette Dec. at 70 (1863-1933) Léon Charles Albert Calmette ForMe...
In less than 5% of the cases, the diagnosis will be suggested as a result of regional or general symptoms: abdominal pain or mass, respiratory distress, gynaecomastia, Virchow's node [10]. Paraclinical examinations Serum tumour markers Measurement of 3 serum markers is recommended before and ...
Medicine sure has some weird measurement systems.Besides the more standardized units like microliters, milligrams, and International Units, we’ve got some odd stuff like French (tubes) and gauge (needles). When dealing with tubes and catheters, the size is usually specified in French units. ...
Interstitial lung disease • High-resolution CT scan • Pulmonary function tests (PFT) with measurement of lung volumes, in particular FVC (spirometry) and total lung capacity (TLC) (spirometry or plethys- mography), measurement of the FEV1/VC ratio, and measurement of cDLCO. • High-...
