By providing increased access and flexibility in employee benefits, employers can not only recruit but retain qualified employees; Providing benefits to employees is seen as managing high-risk coverage at low costs and easing the company's financial burden
While an 18-gauge, or a catheter measuring 0.234 inches (about 5.94 mm), used to be the standard, the development of short peripheral catheters with smaller but stronger walls made it possible to use a smaller size for a larger fluid flow.
The French size is a measure of the external diameter of a catheter (not internal drainage channel). So, for example, if a two-way catheter of 20 Fr is compared to a 20 Fr three-way catheter, they both have the same external diameter but the two-way catheter will have a larger drainage channel than the three-way.Three-way catheters accommodate an extra channel for irrigation within a similar external diameter. round catheter of 1 French has an external diameter of 1â3 mm, and therefore the diameter of a round catheter in millimetres can be determined by dividing the French size by 3: D (mm) = Fr / 3. or. Fr = D (mm) * 3. For example, if the French size is 9, the diameter is 3 mm.
