Valsalva Maneuver | Physiology, Benefits, Dangers 

The best explanation I've watched! Thank you so much Dr.!!!!

Thank you for this man, love your enthusiasm and knowledge. RN's like me need videos like this. THANKS!

All the way from India here. Thank you Dr. Mike for being the best teacher ❤️

the best explanation I've ever had

Thank you Sir for explaining that in detail. I have tachycardia and every kind of defense I can use is a blessing

Thanks doc you've made it much easier than our lecture note wish you the best 👌 🔥

YOU ARE AMAZING AT EXPLAINING THESE CONCEPTS! THANK YOU

Amazing, just the explanation I was looking for. Thank you!

you've earned a subscriber. 🙏🏻 love your lectures.

Thanks for providing one of the easiest and most understandable explanation of valsalva maneuver. Could you also explain its use and effect in change of ambient pressure like during flight descent, diving,etc?

the best explanation online for that maneuver

Thanks a lot for such an amazing explanation! Hope i remember it for the maximum time.

I literally gave a presentation on SVT and the VSM this morning and now this pops up! 😅

Amazing Explanation Dr Mike..Loved it❤

This is one fine doctor. Great explanation too

Thank you. An excellent explanation.

Thank you for sharing this knowledge. This works to manage my SVT episodes until I can get ablation surgery. Works like a charm.

Learned this the hard way while deadlifting. Collapsed with the straps still in my hand. Just muscle strained back THANKFULLY but I lost all feeling in my legs before feeling a surge of heat returning to my legs (which was the blood). My immediate reaction was that I must’ve tore something but now I know better. I also learned just how important breathing out is during a lift. It’s not just for show. It’s to prevent injuries and sudden collapse. *Update* 2 months after initial post: actually herniated the L4-L5 and L5-S1. Have spinal stenosis where the nerve now compresses onto my sciatic nerve. Annnnnd the Doctors say once a disc is herniated it never replaces itself. The herniation may dissolve over time or can be removed surgically but the space where it used to be (the gap leftover from the disc pushing outwards) is said to remain that way for life. Thankfully it wasn’t an extreme herniation. It’s a moderate and mild one. Be safe fellow lifters! I’ve been advised not to Squat or Deadlift ever again but we’ll see how it goes. The biggest factor outside of the weight itself (515) was that I started another set while winded. And I was dehydrated that day. I contemplated getting a sip at the water fountain because I had dry mouth but decided to do it after my final set. Big mistake! Your spines discs are composed of fluid that needs water to retain its shape and structure. Lifting heavy while dehydrated isn’t only bad because you can pass it, it is also bad structurally for your spines strength!

Thank you so much Dr Mike!!

Such a great explanation! Thanks for making it so simple to understand!

Thanks for excellent explanation.

Great explanation! Just what I needed. Please do more!

Great first 2 minutes of this video.

Thanks, that was a very clear explanation.

Wonderful teaching

Well explained. Thanks

Great video. Explains a lot. I notice that when lifting heavy, I'll get episodes of a really high heart rate. This triggering of the sympathetic system triggers a panic attack that makes things worse. I'll try this maneuver next time to lower my heart rate.

I loved and am retired from teaching. You are an excellent teacher!! Thank you for your clear and descriptive explanation of the Valsalva maneuver!! 👍

Always making things simple. Thanks Dr Mike

A masterclass!!!

Thank you sir.❤ Very informative ❤

Excellent explanation 😍

Great explanation

It is a good explanation 👏👏👏👏

Very much helpful

Very well explained, 👍

Great way to learn Physiology.

Great lecture 🎉

Ameizing, greetings from Mexico!!!!!!

Nice explanation of something I've had to use many time to reverse my PSVT. I've also found that if I drink something with carbon dioxide, sparkling water then slightly invert my body and burp that can convert my PSVT episode. I also massage my aorta in my neck to calm myself so I dont go into an episode. Most of my episodes happen when Im playing pickleball.

You make it easy to understand thank you doctor .

Thanks for the highly informational video. You mentioned passing out as a short term consequence from the valsalva maneuver. What about the consequence of blood pressure raising? If one does let's say 1h of repetitive valsalva maneuver 4-5 times a week. Does the higher blood pressure provoke health issues like a rupture of vessels and or other cardiovascular problems?

Nice💯

I severe have mitral valve leak and now with moderate aorta problem , I dont want surgery is there any option?

Excellent ❤️ lecture 👌 😊❤🙏

Hi, do you recommend valsalva maneuver exercise (Pinch your nose closed, close your mouth, and then try to exhale forcefully) to regulate heart rate when experiencing palpitation?

As per @drkaran It's Resetting the Body during Svt

Hello Doctor Matt,the Trendelenburg position also pruduces bradycardia,is the physiological process behind the same as the valsalva?

I didn't understand one thing Why the increase of the vassels resistance => increase the blood return (it's the opposite no ?)

Isn't all of this controlled by the parasympathetic nervous system? Maybe my confusion just comes from the very basic points we were taught about the two nervous systems but I was told parasympathetic controls all subconscious, reactive actions and the sympathetic is when the body starts introducing the brain into the loop and we are able to start reacting with conscious intent. Again, I know I've got to be the wrong one here. I just want to figure out where I'm wrong and fix it.

Can we circumvent the valsalva manoeuvre by decreasing thoracic pressure during heavy lifting? Or does the nervous stimulation not respond, or metabolites override any mechanical circumvention to decrease thoracic pressure?

I live with heart disease right now I have svt and didn't know this could be dangerous for my heart

Ok so in weightlifting is good or bad to do it and does it have any effect on back or disc injuries

Isn't the transient pressure increase also potentially dangerous to someone who already has high blood pressure, or an aneurysm?

So we need to rest after each valsava manuver right? Any suggestions on how long should we take a rest

Does it lower high BP?

Tried several times. Didn't work even though I feel more relaxed. Pulse went up then stayed the same around 90+.

Is this good for people with BAVD?

Todorović? Are you from 🇷🇸? ❤️

Is there something more effective for SVT? The Valsalva manoeuvre seems to only work for a few seconds as you mentioned, then the heart goes back into SVT from normal sinus rhythm?

does an increase in vasoconstriction result in an increase or decrease in blood flow ?

What happens during breath work like that of "Wim Hoff"

Have you ever played a trumpet or trombone? Do you know what "breathe support" is? Have you ever watched a baby sleeping on it's back? Or watched it cry while on it's back? Breathe in, abdominal muscles out, then abdominal muscles tensed and cry. Same for play an instrument. Raising of the shoulders and consciously expanding the ribs outward only as a possible 2nd stage yoga type "topping off", which frankly, very few people do. In fact, we learn to NOT raise our shoulders and breathe from the abdomen. Breath in into the abdomen, which means the diaphragm pushed the intestine downwards and outwards with relaxed abdominal muscles, which then tighten and, tempered by the size of the mouth cavity controled through tongue position (forward towards the teeth and or arched towards the roof of the mouth). Speed of the air being expelled is also tempered by relative jaw position, meaning for slow air speed, the jaw is brought to the point where opne is blowing parallel to the floor, for fast speed, the jaw is retrcted and the air is blow downwards. Of course the lips and the tension in the lips also have to do with the speed of air being expelled and the abdominal muscles help (support) especially in extreme low registers (slow air but a lot) or extreme high registers (fast and little amount of air). The danger to us wind instrument players is the back pressure where not enough air can be expelled quickly enough. Also not supporting it combined with extreme register can cause us to black out. Never happened to me on my present instrument but did when I was playing extremely high trumpet parts and also when playing orchestral flute - not enough resistence can also lead to this happening. The other danger, more prevelant to instrument with high levels of resistence like high trumpets and oboe is the so-called "closed throat". An involuntary attempt to counter the resistence found in the instrument. While I suffereed from this on the trumpet, I never had it on trombone. I was instructed to do this type of breathing, but to hold my breathe in the middle and consciously constrict my abdominal muscles, feeling them also contract at my spine - this to build them up to support (that word again) my L5/S1 disks, ie to take the pressure off them to relieve back pain . this from a physical therapiest specialising in back problems. I noticed immediately that this was extremely similar to what I'd been doing for decades with my musical instruments and "breathe support".

Preshah

First here

...... you are so handsome!!!! Hard to concentrate 😘☺

Dude you explain everything 3-4 times, get to the point man! Video could be at least half as long.

Pretty pathetic...you see this guys motive very easy! So every human being who has a hard push when going to the washroom has died or is going to die? Unreal...get educated.
