I can't say why it persists, but tubing sizes are called "french" because they were invented by a French man who made surgical instruments.
Catheters come in various sizes, typically measured by French (Fr) gauge, where one French unit equals 0.33 mm in diameter. Common sizes range from 6 Fr to 34 Fr, with specific sizes chosen based on the patient's needs and the procedure being performed. Additionally, catheters may vary in length and design depending on their intended use, such as urinary, intravenous, or cardiovascular applications. Always consult a healthcare professional to determine the appropriate size for an individual patient.
'FR' by itself is not a valid two-letter scrabble word according to the official dictionary.
The use of hotmail fr is used by person in the country of France. The hotmail fr is something that lets you know they are in France and not some other country.
