easy dobutamine calculation

Percent Depth Dose (PDD) and Tissue Ratios such as TPR and TMR are closely related. 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. by Jim McGee, BA BS CNMT RT(R)(N) May 30, 2018. 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. Here %DD = 75.3, Sc = 1.008, Sp = 1.009, TMR = 0.82, and OAF = 1.023. 1. Jim has been the Technical Director of an IAC Nuclear/PET nuclear cardiology lab for 11 years. A full correction would require addressing changes to phantom scatter and attenuation (air). Defined as the ratio of dose rate at the reference depth for a given field size to a reference field size. Infuse Dobutamine 500 mg in 250 ml D5W at 5 mcg /kg/min using microdrip tubing. Full buildup in MV photon beams requires large “mini-phantoms.” Because of this, use of TAR in modern clinical calculation is uncommon. The client weighs 182 lbs. Defined as the ratio of output in air for a given field to that of a reference field. 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. I think ung 16.6 is a constant... Kpag nman dopa, 13.3 ang constant...these are for single dose constant.. Hi everyone. Just to show how it was taken, the ff. After logging in you can close it and return to this page. Please log in again. How many mcg/kg/min is your patient receiving? 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. Percent Depth Dose (PDD) is the ratio of dose at a given depth to 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. 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. \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}. Don't worry about, The client weighs 182 lbs. Or just use microset,and the ugtts/min para kayang iregulate manually. Just check the label and compute as is. How many MU per field should be delivered? Would you like an easy way to know your exact total dose of Dobutamine? The same beam has a TMR of 0.913 at a depth of 7cm using an SAD setup. and in this case sabi nga sa observation bakit ka gagamit nang macro set mali nga yung tanong. 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. Know the patient's weight in kg if your calculation is weight based. All you need to do is to understand the problem and to memorize your conversion. TAR is approximately independent of distance from source. The IV bag has 500 mg of dobutamine in 250 mL of fluid. 180cGy is prescribed to a depth of 12cm at a point 5cm off of the central axis. dosage calculations. \begin{equation} \textrm{TMR}(d, r) = \frac{D_d}{D_{d_{max}}} \end{equation}. 4. We can also be contacted directly at support@oncologymedicalphysics.com. I want to share the other formula that we are using to make it simple. Accounts only for scatter arising from treatment head. How do you solve this problem? 3. The login page will open in a new tab. \begin{equation} \textrm{TAR}(d, r_d) = \frac{D_d}{D_{fs}} \end{equation}. Superior reports protect your accreditation, enhance your reputation & improve patient care. \begin{equation} \textrm{TPR}(d, r) = \frac{D_d}{D_{d_{ref}}} \end{equation}. 2. The quickest, easiest & most affordable way to create IAC Nuclear/PET compliant nuclear cardiology reports. 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! Atom 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. Register or login for access to the full knowledge test, ABR Radiation Oncology Qualifying Exam Tests, NCRP 116: Limitations of Exposure to Ionizing Radiation. I hope it will also help the other reviewees:To find the cc per hour, first we need to calculate the concentration. 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). PDD is a function of depth, source to surface distance, and field size. Post Comments tama po ba? ;), may mas mdaling computing tech.wt (kgs) x therapeutic dose devide sa 16.6=single dose82.7x5 /16.6/2 (double dose)= 12.4 sa hospital prating microset (60 dripping factor) ang ginagamit..jun (ER nurse)makati, the answer is 20.15 drops per minute..250ml x 60 gtts/min____________________12.41 ml/hr x 60 min, sir jun pano mo nakuha ung therapeutic dose? Accounts only for scatter arising from the phantom. ), 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). Calculations in mcg/minute. The IV rate is 30 mL/hour. You will be required to solve problems that require you to understand: mcg/kg/min 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. Your patient has a dobutamine IV drip running. Very helpful sa mga nagrerecall like me. Find out what's in your I.V.
