What should be my INR level if I'm taking warfarin?

Aug 28,  · As heparin may affect the INR, patients receiving both heparin and COUMADIN should have INR monitoring at least: • 5 hours after the last intravenous bolus dose of heparin, or • 4 hours after cessation of a continuous intravenous infusion of heparin, or • 24 hours after the last subcutaneous heparin injection. Jan 24,  · For this reason, if you take Coumadin, you must go for regular blood tests that will measure how long it takes for your blood to clot. The test is called prothrombin time test, or protime (PT). The result of the PT is reported as the International Normalized Ratio (INR). When the INR is too low, you have a higher risk of developing a blood clot.

Has 12 years experience. I feel like this is my one big fuzzy area in nursing. Can you explain to me exactly what INR stands for and based on what should inr be if on coumadin numbers how you well, the physician or NP adjust Coumadin therapy?

Thanks so much. Specializes in Utilization Management. Jan 22, Certain conditions or inactivity can cause clotting. Clotting is bad. Heparin and Lovenox work fast, so patients will be given those while in the hospital. Simultaneously, the doc will start them on Coumadin. The reason is that Coumadin takes a few days worth of doses to begin to be effective. You check the INR. Most people have a normal INR of around 1.

It's really not necessary to remember exactly what the letters stand for--I think it's International Normalized Ratioso that wherever you go in the world, the numbers will be the same, so that everyone is on the same page when the numbers come in. When the Coumadin kicks in, the INR should go up. The desired INR will vary for the condition being treated. A person who is an A-fibber will usually go home once the INR reaches around 2. That is why the Coumadin is given at around It then has a chance to peak in the system when labs are drawn for the morning.

Then you'd check in the Dr. Has 44 years experience. Has 10 years experience. Jan 23, Wow, excellent reply Angie O'Plasty! That's a good explanation about heparin acting faster and Coumadin slower. Many pt's how to reset fios ont why they are on both. Also I believe each medication affects a different end of the coagulation cascade remember that from phys class? When I worked in a subacute nsg home, we had a paper printout, much just an insulin sliding scale.

For example, if daily INR was 1. Where I work now, we have a computerized protocol. The computer pulls the daily INR lab results and determines what amount we should give at Sometimes the protocol tells us to call the physician for the amount. While people are in the hospital, they usually have daily INR's. If people are on coumadin for chronic health problems such as stroke or afib like Angie said, then they will most likely go into their family clinic to have their INR's checked every couple of weeks or monthly or so.

Has 28 years experience. Jan 24, Usually while on Coumadin therapy, the INR should what is the definition of eu between 2 and 3. Occasionally the range should be 2. Many things can affect the INR; antibiotics for one, and an increase or decrease in consumption of green, leafy vegetables. Patient's on Coumadin need very good education, stressing the importance of their periodic INR draws.

Too high of an INR can lead to bleeding, etc Specializes in Gerontological, cardiac, med-surg, peds. Has 16 years experience. Feb 10, At least a dozen blood proteins, or blood clotting factors, are needed to clot blood and stop bleeding coagulation. Prothrombin, or factor ii, is one of several clotting factors produced by the liver.

Prothrombin time pt measures the presence and activity of five different blood clotting factors factors I, ii, v, vii, and x. This test measures the integrity of the extrinsic and common pathways of coagulation. The prothrombin time pt measures the clotting time from the activation of factor vii through the formation of the fibrin clot. Adequate amounts of vitamin k are needed to produce prothrombin.

Warfarin coumadin is sometimes prescribed as a "Blood thinner" because it is an effective vitamin k antagonist blocks the formation of vitamin k. The activated partial thromboplastin time ptt measures the function of several other clotting factors, found in what does idv mean in text intrinsic and common blood clotting pathways.

It measures the clotting time from the activation of factor xii through the formation of the fibrin clot. Heparin prevents clotting by blocking certain factors in the intrinsic pathway. Ptt and activated partial thromboplastin time aptt are basically the same thing. Pt is used to monitor treatment with warfarin coumadin.

Once warfarin is discontinued, it usually takes several days to clear it from the system. The ptt test allows the provider to check that there is enough heparin in the blood to prevent clotting, but not so much as to cause bleeding.

Once heparin is discontinued, its blood-thinning effects usually only last a few hours. The inr stands for international normalized ratio. The INR is a method of standardizing the pt for coumadin anticoagulation. Before the INR, different labs using different reagents had different controls and widely differing pt value ranges.

An INRof 1 means the blood clots "Normally" for that pt. The greater the INR, the longer it takes the blood to clot. The warfarin coumadin dosage for people being treated to prevent the formation of blood clots is usually what should inr be if on coumadin so that the prothrombin time is about 1.

A patient may take warfarin to anticoagulate for atrial fibrillation target inr around 2. An inr of 3 means the blood takes about three times as long to clot compared with the normal value for that pt. Has 20 years experience. Feb 17, Has 2 years experience. Feb 25, OK so the if the normal persons blood takes 30 secs to clot a person on coumadin you want their INR to be 2 or 3 so you want their blood to take 60 to 90 secs to clot.

This is Kitt and the info and the links posted here were fantastic. It is proving to be very beneficial to the patients in keeping thier levels in control. Also there is a huge emphasis on patient education when the patient comes into the clinic to be seen and evaluate their lab results.

This provides the patient with a one on one monitoring by a trained person that deals only with Anticoagulation management. Has 7 years experience. Feb 28, I concur, great info already provided!! I'm one of those AC anticoag nurses as the screen name indicates. Mar 29, Apr 1, Very informative Apr 2, Understanding the need for the anticoagulant will lead you to the answer you seek.

Apr 26, I've been a "coumadin cinic" nurse at a large cardiology practice, and loved it. Anticoag therapy is challenging, especially for patients. I agree with the info you've been given. There is a mind boggling amount of info out there concerning this topic. Which is really pretty simple once you get the hang of it. May 20, I can't thank you all enough. I planned on spending this summer really understanding lab values and medication.

The information here is wonderful. Has 14 years experience. May 21, Aug 12, All this is really good info.

Using Coumadin Internat. Normalized Ratio Prothrombin Time by Vaughn Aubuchon: Here is a brief simplified chart of human blood INR Range, showing INR levels, and the factors that affect them.. - This chart illustrates typical therapeutic INR levels, while using Coumadin (warfarin) therapy. Your target INR depends on the condition for which you are receiving treatment with anticoagulation. The most common INR range for patients is to "Low-intensity" is to and "high-intensity" is to Continue Learning about Anticoagulant. Patients who take warfarin should consult with their healthcare provider before taking any new medication, including over-the-counter (nonprescription) drugs, herbal medicines, vitamins or any other products. Many medications can alter the effectiveness of warfarin, resulting in an INR .

In the previous version of this guideline , Table 2. Pre-existing conditions associated with higher and lower risk of thrombosis , the conditions for higher and lower risk of thrombosis were reversed. This has since been corrected PDF , page 3. Perioperative management of non-vitamin K antagonist oral anticoagulants can be found in BCGuidelines. Non-perioperative management of warfarin is covered in BCGuidelines. The management of warfarin therapy in patients undergoing surgery or other invasive procedures involves a fine balance between the risk of hemorrhage if the procedure was performed while on warfarin, and the risk of thrombosis if warfarin was discontinued.

The thrombotic risk in the perioperative period depends on pre-existing conditions, the time since the last episode of thrombosis , and the thrombotic effect of surgery. It is recommended that the anesthesiologist and the surgeon be consulted in determining the hemorrhagic risk. Patients with a high risk of thromboembolism or stroke may benefit from bridging with heparin during the preoperative period, either as outpatients LMWH subcutaneously or inpatients unfractionated heparin intravenously by shortening the duration of subtherapeutic anticoagulation.

Postoperative management of warfarin therapy consists of re-initiation of anticoagulation. Postoperative anticoagulation increases the rate of major bleeding. Restarting warfarin may be delayed in neurosurgical patients, those receiving epidural analgesia and in patients who are bleeding. For patients at high risk of thrombosis, LMWH by injection is given concurrently with warfarin and the overlap is maintained until a therapeutic INR has been reached.

LMWH used postoperatively may allow earlier discharge of the patient compared with using unfractionated heparin. When reversal of anticoagulation is required within 6 hours, intravenous vitamin K and prothrombin complex concentrate PCC e. Table 1. Procedures associated with high and low risk for bleeding.
