Why Do Doctors Use Stethoscopes?

Got a question? Let me know! :)

How is sound amplified in a stethoscope?

[@DocUnlock]

It's actually a really neat application of physics: the part of the stethoscope that is placed on the skin is called the diaphragm. Sound waves that are produced inside the body (like the sound of heart valves) make the diaphragm vibrate. The vibration of the diaphragm transmits the sound into the hollow rubber tube, which then leads to the ear pieces. The amplification happens for 3 main reasons: 1) Without a stethoscope, sound waves from inside the body would travel outwards in all different directions. The diaphragm 'collects' all of these sound waves, and channels them in a specific direction (i.e. up the rubber tube and then to the ear pieces). 2) The size of the diaphragm is much larger than the opening of the ear piece. This means that the vibrations of the diaphragm are funnelled to a small area within the ear piece. 3) The ear piece is placed very close to the ear drum so that the sound is not lost to the environment. The design for the stethoscope that Rene invented is said to be inspired from an ear trumpet. You can read more about them here: en.wikipedia.org/wiki/Ear_trumpet Thank you for the question!

Except mbbs and nursing who use stethoscope in med. Field.?

[@dr.anonymous8005]

Cann u explain why sustained release, Prolonged release etc' Modified release, gastro resistant & IP,BP,USP is written in medicines???

Bless Dr Laennec for being modest!

[@DocUnlock]

A true gentleman indeed!

[@jmm1233]

not just the stethoscope , they have bundles of wooden lollipop sticks , sometimes the old tech is useful for quick diagnostics

[@farisatar383]

If René didn’t invent the stethoscope 90% of the men would have became doctors 😂😂

[@caribaez5711]

you got great content. please upload more. :)

[@DocUnlock]

Thank you Cari! Yup I'll be uploading more in July

[@mukeshkanna.v925]

@@DocUnlock super sir. Please upload uses of other clinical instruments.

[@bobateasedits]

Extremely underrated! You deserved more views and likes 😊

EMT Here. Use the stethoscope all the time since in a field setting we don't have a lot of other tools. Mostly for taking blood pressures and auscultating the lungs (and occasionally the upper airway), but it is pretty much useful for anything in the human body you can hear. I've seen a salty old paramedic use it to increase their index of suspicion for a tib fracture by auscultating one end and tapping the other with the handle of their shears, for example. They did put it in the report and it caused... some discussion to say the least! A review of literature showed that such a technique was dated but valid

thank you dr the video was so entertaining and beneficial i am year 1 medical student and i'm learning the basics

[@dhrubojyotichakravorty4617]

Hi Dr. Ankit, thanks for this brilliant and crisp video. I like the part where you made us hear different heart beats. Cna you do that for other parts of the body like the Lungs and Intestines.

My brother wants to be a doctor so I know why he hugs me on the top of my back Btw he’s 6

[@subratabhowal41]

Focus on right choice or approach in the riht spirit for diagnosis of heart ailments and associated illmess.

[@blessyponnachen9528]

Which all medical specialization doctors use stethoscope while they diagnose patients?

[@jiechang1508]

i still want to learn more about heart from you

[@blessyponnachen9528]

Hi I would like to ask you that from where do you collect the heart sounds used in this video . Is it from patients or a platform where companies or doctors can use for purposes like these ?

[@sakthi7184]

Nice video 👍👍👍👍

[@alvinhenna4537]

Is the information correct?, if yes then I'm gonna represent this in my skul project

[@lookatcha]

you have an awesome beard

[@stethoscope1817]

No, you don't get rid of us!! ;)

[@spytonic4171]

can you make a video about fissures some say it is because of lack of fiber and some are saying it is because of eating fiber and why they come again and again if possible cover piles also please Thanks in advance !

[@duydang2879]

Behind the diaphragm there is a smaller rounded part. What is that and what is it function?

[@DocUnlock]

I think you're probably referring to the bell of the stethoscope. The bell is better for low pitched sounds that may not be strong enough to vibrate the diaphragm. This can be useful for certain heart murmurs that are difficult to hear (eg diastolic murmurs)

[@tGoldenPhoenix]

thank you

[@para9676]

others than aortic stenosis , whats are the sounds that we can use stethoscope to hear it ?

[@jonathan49731]

So if this didn’t exist a lot of creeps would go for being a nurse or doctor

[@divyatdbnawa.122]

The stethoscope is only patter for doctors to seem like they are doing something worth paying money for.
