Your patient weighs 65 kg. Accounts only for scatter arising from treatment head. \begin{equation} \textrm{TMR} = \textrm{PDD} (\frac{SSD + d}{SSD + d_{ref}})^2(\frac{S_p(r_{d_{ref}})}{S_{p}(r_d)}) \end{equation}, \begin{equation} PDD = TMR (\frac {SSD + d_{max}}{SSD + d})^2 (\frac{S_p(r_{d_{max}})}{S_{p}(r_d)}) \end{equation}, \begin{equation} TMR = \frac{TAR}{BSF} \end{equation}, \begin{equation} TPR = \frac{TMR(d)}{TMR(d_{ref})} \end{equation}. These Dopamine drip practice problems were designed to help you better understand how to calculate an IV flow rate based on a patient's weight, the ordered dose, and the amount of solution supplied. tama po ba? Full buildup in MV photon beams requires large “mini-phantoms.” Because of this, use of TAR in modern clinical calculation is uncommon. Save time, make your life easier & add value to your nuclear cardiology lab. Although direct measurement is always preferred, it is useful to have an understanding of how to convert between these quantities. formula was used:(Stock/vol) x (1,000mcg/1mg) divided by 60mgtts/ml=500mg/250ml x (1,000mcg/1mg) divided by 60mgtts/ml= 33.33 mcg/mgtts (concentration)To find cc/hr= desired dose x weight divided by conc.= 5mcg/kg/min x 82.7kg divided by 33.33mcg/mgtts=12.4 mgtts/min (which is the same with cc/hr), a) Convert the weight from lbs to kg. Infuse Dobutamine 500 mg in 250 ml D5W at 5 mcg /kg/min using microdrip tubing. BSF is a special case of TAR evaluated at depth of maximum dose (d. BSF is highest for low energies and large field sizes. Determine the ml/hr and the. Ordered amount of drug = X Dose/mL (Drug concentration) = 500/250 = 2 mg/mL Convert to mcg = 2000 mcg/mL Patient weight 65 \( AF = \frac{\textrm{Output with applicator}}{\textrm{Output with reference applicator}} \), The cutout factor is the ratio of output with the cutout placed in the applicator to the output of the applicator with no cutout in place. Although many prescriptions will simply define the prescription dose to be the 100% isodose lines, special cases (such as electron treatments and stereotactic radiosurgery) may not. The formulas and step by step procedure has been helpful. 1. Defined as the ratio of dose rate at the reference depth for a given field size to a reference field size. paturo ako :) please tahnky ou, hello po!if me nakakabasa nito, triny ko po ung way ko pagsolve ng dopamine sa problem ng dobutamine prob eh same po ung answer ng 12.4ml/hr... eto po ang link sa youtube... mas madali po actually...https://www.youtube.com/watch?v=VMc_2lDoqNw, hello po! bottle (drug concentration or number of mL of fluid).

TMR is a special case of TPR with the reference depth taken as depth of maximum dose. (1kg/2.2lbs), NOTE: Stock dose varies, there is what we call Double dose which simply means that the dosage of the stock medicine is greater. Would you like an easy way to know your exact total dose of Dobutamine?.

Find out what's in your I.V. How do you solve this problem? The American Heart Association (AHA) has provided the fol-lowing formula, multiply 6 times the weight in kg times the desired dose in µg/ kg/min, divided by the desired amount of fluid to infuse in ml/h which provides the amount of dopamine in mg to add to each 100 ml solution prepared. Register or login for access to the full knowledge test, ABR Radiation Oncology Qualifying Exam Tests, NCRP 116: Limitations of Exposure to Ionizing Radiation. Percent Depth Dose (PDD) is the ratio of dose at a given depth to maximum dose. Tissue Maximum Ratio (TMR) is the ratio of dose at a given point and depth in phantom to dose at the same point at the depth of maximum dose in phantom. Tissue Phantom Ratio (TPR) is the ratio of dose at a given point and depth in phantom to dose at the same point at the reference depth in phantom. We know that the given above is a double concentration of dopamine (33.33). Or just use microset,and the ugtts/min para kayang iregulate manually. Mayneord’s F factor the ratio of the inverse square component of percent depth dose (PDD) from the reference souce-to-surface distance (SSD) to another SSD. Please log in again. For example, a physician may prescribe to the 90% isodose line in which case TT would be taken as 0.9. Determine in which units your drug is measured (units/hour, mg/hour, or mcg/kg/minute). A 10MV photon beam has a PDD of 0.839 at a depth of 7cm using an SSD setup. The contribution of scatter to clinical dose calculations depends on both the amount of scatter generated in the treatment head and the amount of scatter generated within the phantom. the answer 3gtts/min is wrong..12.41 ml/hr x (1 hr/60 min) x (60gtts/ml) == 12.41 gtts/min... to anonymous above:kung ang drop factor mo is 60 (microdrip tube) then 12 ang sagot, if 20 then 4 or kung 15 then 3 ang sagot, in this case 15 yung ginamit kasi drops/min yung hinahanap hindi microdrops(ugtts)yung (60ugtts/mL) yan yung nagiiba, pwede din yan maging 20gtts/min or 15gtts/min depende sa drop factor. Your patient has a dobutamine IV drip running. How many MU per field should be delivered? The backscatter factor (BSF) is the ratio of dose at depth of maximum dose in the phantom (Dmax) to dose at the same point in free space (Dfs) with full build-up.

by Jim McGee, BA BS CNMT RT(R)(N) May 30, 2018. All you need to do is to understand the problem and to memorize your conversion. A full correction would require addressing changes to phantom scatter and attenuation (air). Note that only PDD is used in photon calculations. Assuming a prescription depth of 7cm, which setup would have a higher maximum dose and by how much? Key Point: While Mayneord’s Factor is accurate for small shifts, it only accounts for the effect of inverse square law on PDD. Key Point: In MU calculations, Collimator Scatter Fractor should always be taken as the field size at the central axis. Don't worry about, The client weighs 182 lbs. 3.

Measure output for various field sizes in phantom which exceeds dimensions of maximum field size. I think ung 16.6 is a constant... Kpag nman dopa, 13.3 ang constant...these are for single dose constant.. Hi everyone. Defined as the ratio of output in air for a given field to that of a reference field. we arrived at same answer po which is 12.4ml/hr pro ung formula na ginamit ko is ung sa pagsolve ng dopamine problem... eto po ang tutorial nakita ko sa youtube...mas simplified po and youre dealing with small numbers lng po..https://www.youtube.com/watch?v=VMc_2lDoqNw. ung 16.6 atsaka ung double dose? \begin{equation} \textrm{TAR}(d, r_d) = \frac{D_d}{D_{fs}} \end{equation}. All you need to do is to understand the problem and to memorize your conversion. Post Comments PDD is a function of depth, source to surface distance, and field size.
Accounts only for scatter arising from the phantom. Defined as the ratio of dose rate for a given field size at a reference depth to the dose rate at the same depth using a reference field size, May be determined for all field sizes by \( S_p = \frac{S_{c,p}}{S_c} \), For PDD calcualtions this may be taken as \( (\frac{Source-to-Calibration-Depth}{SSD + d})^2 \), For TMR calculations this may be taken as \((\frac{Source-to-Calibration-Depth}{SAD})^2 \). The same beam has a TMR of 0.913 at a depth of 7cm using an SAD setup. Calculations in mcg/minute. The login page will open in a new tab. Although many prescriptions will simply define the prescription dose to be the 100% isodose lines, special cases (such as electron treatments and stereotactic radiosurgery) may not. \begin{equation} \textrm{TMR}(d, r) = \frac{D_d}{D_{d_{max}}} \end{equation}. The applicator factor is the ratio of the the output with the utilized applicator to the output of with the reference applicator size (typically 10cm by 10cm). Contact us if you have any questions, ideas for content, or other suggestions. I want to share the other formula that we are using to make it simple.

2. \begin{equation} \textrm{MU} = \frac{Rx}{O \times (factor) \times S_c(r_c) \times S_p(r) \times ISC \times TT \times WF \times TF \times OAF } \end{equation}, \begin{equation} \textrm{MU} = \frac{Rx}{O \times PDD \times AF \times CF \times TT \times ISC } \end{equation}. I hope it will also help the other reviewees:To find the cc per hour, first we need to calculate the concentration. dose (mcg/kg/min) x weight (kg) x 60 min/hr concentration (mg/cc) x 1000 mcg/mg Created: Friday, December 28, 2001 Last Modified: The client weighs 182 lbs. For TMR calculations this may be taken as \((\frac{Source-to-Calibration-Depth}{SAD})^2 \) TT is the treat to level, taken to be 1 if isodose line is not specified. Would you like an easy way to know your exact total dose of Dobutamine? Compute the required monitor units for a 6MV beam delivered 105SSD with a field size of 12x12cm2. Simple & Free Online Calculator: Do you perform Dobutamine Stress Tests for Nuclear Cardiology or Echocardiography?. Tissue Air Ratio (TAR) is the ratio of dose at a point in the phantom (Dd) to dose at the same point in free space (Dfs) with full build-up. 4. ), Find the dosage for every total weight of the patient, Convert your stock dose so that you can cancel the units or use the popular formula D/S*Q, We can now use the popular formula D/S*Q (desired / stock * quantity). Step 1 - Know the given: 500mg/250ml (may 500mg na Dobutamine sa bawat 250 mL na hawak mong gamot galing pharmacy/ stock dose) 5 mcg … Jim has been the Technical Director of an IAC Nuclear/PET nuclear cardiology lab for 11 years. Determine the ml/hr and the gtts /min. \begin{equation} \textrm{TPR}(d, r) = \frac{D_d}{D_{d_{ref}}} \end{equation}. Percent Depth Dose (PDD) and Tissue Ratios such as TPR and TMR are closely related. Know the patient's weight in kg if your calculation is weight based.

The exact amount of non-radioactive pharmaceuticals administered is an  IAC Nuclear/PET “ICANL” report requirement: Maximum dose is also a requirement for ICAEL / IAC Echocardiography: The Quickest, Easiest, Most Affordable Way to Create IAC ​​​​​Compliant Nuclear Cardiology Reports. ^_^ Mahirap nga i-regulate ang 3gtts/min,siguro nag-assume yung nagtanong nyan na gagamit ka ng infusion pump. Absorbed dose at a point is a function both of primary and scattered photons.

\begin{equation} \textrm{BSF}(r_{d_{max}}) = \frac{D_{max}}{D_{fs}} \end{equation}.

Just check the label and compute as is. Thanks. Accounts for scatter arising from both treatment head and within the phantom. The F factor is used to convert PDD curves from one SSD to another, for the same depth and collimator setting.
