# LearningTools: Reading Height Measurements on a Physician Mechanical Beam Scale with Height Rod

hi I’m Josh Ferguson and this is reading height measurements on a physician mechanical beam scale with adjustable height rod by the end of this lesson you will interpret the calibration markings on the adjustable height rod of a physician mechanical beam scale and determine the height indicated on height rods width and without the number of feet indicated on the rod let’s begin here are the parts of the height rod that we will focus on today the lower rod with the indicator line and the upper rod with the headpiece the lower rod also called the outer rod is stationary and cannot be adjusted the upper rod also called the inner rod is the adjustable portion of the height rod it can be raised and lowered as needed the headpiece which is currently in its resting position extends and is placed on top of the patient’s head during height measurement the indicated line is also called the read line some rods also include a read arrow you will determine the patient’s height by observing the indicator line and calibration markings here’s a general overview of how the height rod works the patient steps on the platform raise the height rod so the headpiece is above the patient’s head lower the headpiece on to the patient’s head make sure the headpiece is flat if it is slanted downward or upward you will produce an inaccurate result remember make sure the headpiece lays flat on top of the patient’s head now that you have a general concept of how the height rod works we will now focus on interpreting the calibration markings on the height rod the logo rod is generally used for those who have a standing height of less than three feet four and three-quarter inches let’s look at each of the calibration markings on the lower rod closely we will focus only on the right side of the rod since our concentration is in feet and inches and not in centimeters notice that you have lines for feet inches and fractional inches the fractional lines represent quarter half and three quarters on the lower rod the numbers increase from bottom to top for example here is a three foot line this line represents three feet and a quarter inch this line represents three feet and a half inch in this line represents three feet and three quarters of an inch and this line represents a height of three foot one inch let’s practice a few state the height and feet and inches according to the marker if you stated three foot three inches you are correct here’s another if you stated three foot four and a quarter inches then you understand the calibrations on the bottom rod completely let’s see if you can master the upper rod as well remember with the bottom rod the numbers increase from bottom to top well on the upper rod the numbers increase from top to bottom let’s see why this makes a difference we will compare the fractional lines between two and three inches on the bottom right and the top rod on the bottom bar on the left image the fractional line that represents the two and a quarter inch mark is here the two and a half inch mark is here and a two and three quarters of an inch mark is here now on the Opera R and the right image the fractional line that represents two and a quarter inches mark is here the two and a half inch mark is he and a two and three quarters of an inch mark is here remember the bottom rod numbers increase from bottom to top the upper rod numbers increase from top to bottom the simplest way to interpret the calibration markings correctly is to observe the direction that the whole numbers are increasing then you will be able to interpret the fractional markings correctly now here’s some good news if you’re measuring someone who is taller than the height of the bottom rod you can ignore the numbers on the bottom right completely and focus on the upper rod and indicator line for the rest of this lesson we will focus on using the upper rod and reading from the indicator line now that you have learned the basics let’s determine a patient’s height and feet and inches in this image the patient’s height is five foot three and a half inches here’s how this was determined once the patient is on the platform with the headpiece flat on their head follow these steps step one find the number of feet nearest to the indicator line in this case it is five feet step to find the nearest whole number in inches in this case it is 3 inches step 3 find the fractional inch closes – or on the indicator line in this case it is in half an inch and step 4 document the final result in this case you will document the height as five foot three and a half inches it’s your turn what is the height indicated on the height rod I’ll lead the steps there for you for the first one pause the video then play it when you’re ready for the answer if you stated five foot four and a quarter inches you are correct now try it without the steps in view what is the height indicated on the high rod if you stated six foot four and three-quarters of an inch you are correct great job next we will examine a hydride that only has the number of inches you will notice that there are no feet calibration markings on this hydride for this type of rod you must know how to correctly convert the number of inches to feet and inches to do this you must know your multiples of 12 I strongly suggest that you know at least up to 12 times 7 without having to even think about it as you see a person who is 36 inches is 3 feet tall 48 inches is 4 feet tall 60 inches is 5 feet tall and so on quickly what’s 12 times 7 if you stated the answer before it appeared great job if not don’t worry you just have some studying to do remember commit to knowing that multiples of 12 up to 12 times 7 to memory I say up to 7 because very few people are above 7 feet tall let’s practice applying the multiples of 12 to measure a patient’s height correctly in this image the height indicated is 4/5 7 and 3/4 of an inch how was this determined here’s how step 1 find the whole number inches nearest to the indicator line in this case it is 55 inches step 2 convert the whole number of inches to feet if the patient is 55 inches tall that means there are at least 4 feet tall we will document the number of feet as 4 feet step 3 determine the remaining whole number of inches since the patient is 55 inches and 48 inches equals 4 feet there is a remainder of 7 inches document this in your answer so far we know that the patient’s height is at least 4 feet 7 inches now let’s add the fractional inches to complete the patient’s height step 4 find the fractional inch closest to the indicator line in this case it is 3/4 of an inch step 5 finally add the fractional lines to your answer in this case the patient’s height is 4 foot seven and three quarters of an inch now it’s your turn determine the height indicated on the height rod I’ll leave the steps there for you for the first one you may pause the video and play when you’re ready for the answer if you stated 4 foot nine and a quarter of an inch you are correct now try it without the steps in view what is the height indicated on the height rod if you stated five feet and a half an inch you are correct as you have noticed knowing the multiples of 12 is very important don’t get caught counting on your fingers document the patient’s height quickly and accurately and there you have it you have learned to interpret the calibration markings on the adjustable height rod of a physician mechanical beam scale and determine the height indicated on the height rods with and without the number of feet indicated on the rod if you found this video helpful please make sure to click the like button to stay up to date on other great allied health learning tools subscribe to my youtube

love this thank you

Thank you sooo much! I feel better about doing physicals now.

This was such a helpful tool to discover, I'm studying for my CNA test, thank you!

Omg I take my intro to healthcare final in a week and this has helped tremendously you took time explaining how you got the answer and I really understand it now… You are a lifesaver

I suck in math this is going to be a nightmare for me..Im doomed.

Very helpful 👌

very helpful

Thank you

Thank you so much. Just started working in a clinic and your tools were amazing thanks for teaching a dummy in measuring the heights don't stop

very informative

Mr. Farquharson, these videos you created are highly helpful. You speak crystal clear when demonstrating step by step procedures. Is it possible if you created more educational videos? Thank you.

I can not believe how this video helped me too much, you are a super helper

Awesome👍 This Video dumbed it down for me perfectly!! Thanks

Very,very,very helpful and simple 👌

This video helped me learn how to measure height !! Thank you so much !

If you want to know what 55 inches is you divide 55 by 12 which is 4 ft 7 in.

Tailor tape height is equal to stadio meters height ? I'm tried in my home with tailors tape it was shown 5feet 6.5 inches which is accurate

To whomever cannot understand this tutorial is slow . This informative piece was damn helpful . Thanks ! 😆

Such OF good explanation infinity 👍👍👍👍👍

WERE THERE IS NO DOCTOR NURSES CAN PLACE OBSRV

Thank you helpful hits

Well I read it wrong when the doctor measured me so I gues I got to wait another year to be measured proper because it’s always different when people I’m family do it.

Thank you from Nigeria

57 is also close to 6o

Really helpfull

🙈🙈🙈

Excellent!!!

Amazing video I finally learned

Thank you so much! My instructor did not explain any of this!! 😣

k

Wow! its the best of the best! i been looking for some videos and i didnt understand anything!!!

Plus in this video if you go to their page http://www.alliedhealthtools.com they give you free exercices! Is not the best?

Thank you sooo much! you save me!

this satdio meters don't measure height accurately

Thank you so much for this video. You have no idea how much this has helped me. Unfortunately, I did not know how to do this, and let’s just say I do now. That’s all that matters. Thank you!

I got it!!! Thank you so much!!!

So good to learn

Excellent. Better than MA school.

"Quick, what's twelve times seven?"

Me:

freezes like a deer in headlightsPTSD returnsThank you!!! Very helpful!

I will count on my fingers.

I just measure my height earlier and I can't read or determine how the adjustable height rod works, so that's the reason why I'm here studying how to measure HAHAHAHA

Im 170+ cm
