Refimprove date July 2011 The Frenchscale or French gauge system is commonly used to measure the size of a catheter . It is most often abbreviated as Fr, but can often abbreviated as Fg, FR or F. It may also be abbreviated as CH or Ch for Joseph Fr d ric Beno t Charri re Charri re , its inventor in French speaking countries. A catheter of 1 French has a diameter of mm, ref cite web url http www.wolframalpha.com input ?i 1 french title 1 French publisher Wolfram Alpha accessdate 20 March 2012 ref and therefore the diameter of a round catheter in millimeters 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. An increasing French size corresponds to a larger diameter catheter. This is contrary to Needle gauge comparison chart needle gauge size , where an increasing gauge corresponds to a smaller diameter catheter. The french size is a measure of external diameter of the catheter not internal drainage channel . So, if a 2 way catheter of eg. 20 Fr is compared to a 20 Fr 3 way catheter then they both have same external diameter but 2 way catheter will contain larger drainage channel than 3 way. 3 way catheters accommodate an extra channel for irrigation in the similar external diameter. The French gauge was devised by Joseph Fr d ric Beno t Charri re, a 19th century Parisian maker of surgical instruments, who defined the diameter times 3 relationship. ref cite journal pages 545 8 doi 10.1016 0736 4679 87 90218 6 title J.

A balloon catheter is a type of soft catheter with an inflatable balloon at its tip which is used during a catheterization procedure to enlarge a narrow opening or passage within the body . The deflated balloon catheter is positioned, then inflated to perform the necessary procedure, and deflated again in order to be removed. Some common uses include angioplasty or balloon septostomy , via cardiac catheterization heart cath tuboplasty via uterus uterine catheterization Angioplasty balloon catheters Balloon catheters used in angioplasty are either of Over the Wire OTW or Rapid Exchange Rx design. When a balloon catheter is used to compress plaque within a clogged coronary artery it is referred to as a plain old balloon angioplasty or POBA. Balloon catheters are also utilized in the deployment of stents during angioplasty . Balloon catheters are supplied to the cath lab with a stent premounted on the balloon. When the cardiologist inflates the balloon it expands the stent. When the cardiologist subsequently deflates the balloon the stent stays behind in the artery and the balloon catheter can be removed. Stents that are used in conjunction with a balloon catheter are known as balloon expandable stents.

File Arterial kateter Seldinger .jpg thumb Arterial catheter Seldinger technique File Arterial kateter.jpg thumb Arterial catheter Punktion technique An arterial line , or art line , or a line , is a thin catheter inserted into an artery . It is most commonly used in intensive care medicine and anesthesia to monitor the blood pressure real time rather than by intermittent measurement , and to obtain samples for arterial blood gas measurements. It is not generally used to administer medication. Since many injectable drugs used in intensive care and anesthesia , such as sodium pentothal , may lead to serious tissue damage and even amputation if given in an artery the arterial line must be clearly marked to avoid accidental intraarterial injection of intravenous drugs. An arterial line is usually inserted in the wrist radial artery but can also be inserted into the elbow brachial artery , groin femoral artery , foot dorsalis pedis artery . Insertion is often painful however an anesthetic such as Lidocaine can be used to make the insertion more tolerable and additionally help prevent vasospasm thereby making cannulation of the artery somewhat easier.

Multiple issues no footnotes July 2011 unreferenced July 2011 wikify July 2011 Intermittent catheterisation is an effective technique for people who need catheter based bladder management. Intermittent catheterisation is considered the gold standard of care for bladder emptying, and this approach is supported by several international and national guidelines on urinary incontinence. The principles of using intermittent catheterisation are based on regular and complete emptying of the bladder to maintain a low bladder pressure and minimal residual urine volumes, consequently securing bladder and renal health. Correctly performed intermittent catheterisation is a safe method suitable for long term use, minimising the risk of urological complications e.g. those relating to bladder and kidney dysfunction, Urinary tract infection urinary tract infection UTI , urethral stricture s and male infertility and improving a person s quality of life. People who benefit from intermittent catheterisation include those with neurogenic spinal cord injury, spina bifida and multiple sclerosis and non neurogenic bladder disorders infravesical obstruction due to prostate enlargement, urethral strictures and post operative urinary retention .

It is a sliding secondary scale that is used to indicate where the measurement lies when it is in between two of the marks on the main scale. Verniers are common on sextant s used in navigation , scientific instrument ... instruments, the measure is read off a finely marked data scale the fixed scale, in the diagram . The measure taken will usually be between two of the smallest graduations on this scale. The indicating scale vernier in the diagram is used to provide an even finer additional level of precision without ... mm is read off from the upper fixed data scale. The 0.58 mm is obtained from the lower sliding indicating scale at the point of closest alignment between the two scales. The superimposed red markings ... whether the right value is 0.58 mm or 0.60 mm small History The vernier scale was invented in its modern form in 1631 by the France French mathematician Pierre Vernier 1580&ndash 1637 . Its use was described ... at a finer level of measure. File Vernier scale Direct vernier.gif thumb Vernier scale Direct vernier Direct vernier Direct verniers are the most common. The indicating scale is constructed so that when its zero point is coincident with the start of the data scale, its graduation instrument graduation s are at a slightly smaller spacing than those on the data scale and so none but the last graduation coincide with any graduations on the data scale. N graduations of the indicating scale would cover N 1 graduations of the data scale. File Vernier scale Retrograde vernier.gif thumb Vernier scale Retrograde vernier Retrograde vernier Retrograde verniers are found on some devices, including ... except its graduations are at a slightly larger spacing. N graduations of the indicating scale would cover N 1 graduations of the data scale. The retrograde vernier also extends backwards along ... more details
