Coagulation or blood clotting is a protective mechanism of the body against bleeding. When damage occurs to a blood vessela series of reactions take place involving substances found in the blood known as clotting factors. They are called this because they contribute to the formation of a blood clot. Normally, clotting only occurs when there is blood loss from a damaged blood vessel.
However, there are several what does i & r mean in medical terms that can cause blood clots to form in the absence of active bleeding. When this occurs, a person may be at an increased risk of thromboembolic disease. In thromboembolic diseasefragments of blood clots dislodge and circulate in the blood, potentially obstructing blood vessels in the lungs and causing pulmonary embolismor vessels in the heart and causing heart attackor in the brain and causing stroke.
These conditions are all potentially fatal. Therefore, when a person is at high risk of one of the above conditions e. People who require long-term anticoagulant therapy are usually given warfarinan anticoagulant that can be taken in the form of a tablet instead of injection. This is often referred to as oral anti-coagulant therapy. The international normalised ratio INR is a laboratory measurement по ссылке how long it takes blood to form a clot.
It is most romantic places to denver to determine the effects of oral anticoagulants on the clotting system. Devised inthe INR provides a standardised method of reporting the effects of an oral anticoagulant such as warfarin on blood clotting. Prior to this, the effects of warfarin on blood clotting were determined by a laboratory measure known as prothrombin time.
Measurement of prothrombin time has its advantages, including that it is cheap and simple to perform. However, the disadvantage of this measure is that there can be large differences in the values obtained, depending on which laboratory the value was obtained from — different commercial measuring systems can produce different results. Therefore it is impossible to compare results that come from different laboratories. In an attempt to overcome the variability between laboratories, prothrombin times were initially expressed as a ratio of the prothrombin time of a control value.
The control value was the average of prothrombin times from 20 or more healthy subjects. While expressing prothrombin times смотрите подробнее to a control value was seen as an improvement, it was still insufficient.
The ISI is a numerical value representing the responsiveness of any given commercial system relative to the international standard. It takes into what does i & r mean in medical terms the variability in results obtained using взято отсюда commercial systems in calculating the result.
In this way, results from different laboratories and countries can be compared more readily. We regularly monitor the INR of people using warfarin in order to balance the risk of excessive bleeding when the INR is too high, meaning that the blood is too thin against the risk of clotting or thrombosis when the INR is too low or the blood is too thick.
INR values over 4. Evidence suggests that more frequent testing will result in more time within the desired INR target range. Monitoring then occurs every 2—3 days for the next few weeks, and then with decreasing frequency depending on the stability of the results.
If the INR remains stable, testing can be spread as far apart as every four weeks. Many medications, foods and even concurrent illness are known to interact with warfarin and therefore interfere with подробнее на этой странице INR.
These affect the way warfarin is processed by the body. Therefore, you should consult your doctor if you:.
The desired INR depends on the reason why you need anticoagulation. The three most common reasons for warfarin use, along with their target INRs, include:. INR can be monitored either by laboratory blood testing or by using a portable monitoring device. Laboratory blood testing is the traditional practice in Australia. Blood is drawn from a vein, typically by a GP, and sent to the laboratory for testing.
What does i & r mean in medical terms is a what does i & r mean in medical terms delay before results are returned to the GP, who analyses the need for dose adjustment with the help of computerised algorithms. The practitioner will then let what does i & r mean in medical terms know whether a dose adjustment is needed.
A dose adjustment will be required if your INR value for the test is outside the therapeutic range too high or too low. Portable devices, introduced in the s, allow you, your doctor or another health practitioner e. The blood drop is placed on a test strip which is inserted into the portable device so that the clotting time can be measured. These devices have been demonstrated accurate and reliable and to provide reproducible results which are similar to those obtained through laboratory testing.
If the device is used for monitoring in a health facility, a health practitioner often a nurse conducts the blood test and records the result on your behalf. In consultation with the doctor prescribing warfarin or based on a computerised algorithm, the health practitioner can notify you immediately if any dose adjustments are necessary.
Benefits have been associated with this testing method. In particular, obtaining on the spot what does i & r mean in medical terms enables better management of oral anti-coagulation therapy, as dose adjustments can be made immediately and discussed with the health practitioner face to face rather than over the phone. Some people also prefer not needing to have blood drawn from a vein using a needle with this method.
When a portable device is used for home monitoring, you usually conduct the test yourself. However, in some countries health practitioners can visit you in your homes or aged care settings to conduct blood monitoring. This enables you to have your INR monitored without the inconvenience of attending a healthcare facility.
Self-testing has the advantage of being more convenient and making it easier for you to take the correct dose of warfarin at the correct time. People who use this method are more likely to monitor their INR more frequently. They are also less likely to experience blood clot or bleeding complications. These reductions may be the result of people who self-test spending more time within the therapeutic range, due to more frequent monitoring and more timely dose adjustments. On what does i & r mean in medical terms spot results enable immediate adjustments to the warfarin dose.
It may also be particularly beneficial for individuals who need to travel long нажмите чтобы перейти to attend a clinic for laboratory blood testing. There are, however, some limitations with this model of INR monitoring. It can cause some individuals to become more anxious about their health and in these people, without proper support and supervision from a health professional, their INR regulation may be poorer.
Of those people who did agree and attempted INR self-monitoring, The main reasons for this included physical limitations, problems attending training sessions, failing training assessments, and problems with the device.
