Respiratory Therapy - Deadspace, Alveolar Tidal Volume and Alveolar Minute Volume 

I'm a 30yr RT veteran and I enjoy watching your videos. Great refreshers for us "seasoned" therapists and useful tips for teaching our students.

Your videos are getting me through my second year as an RT student. I keep learning English as I go, when I don’t understand something in school because professors speak fast your videos have helped me a lot. I’m not going to give up! Thank you for all you do for us!!!! 🙏🏼

Your ability to break it all down is incredible. As a first semester, first-year student, during COVID, hybrid learning has presented many challenges. This channel is a life-saver in terms of high-level comprehension, application, and in turn, retention. Thank you, Thank you, Thank you!

Is there a HUG button apart from LIKE? Because that's what I want to do now with you for your priceless teachings!

You are getting me through RT school by the skin of my teeth, coach. Appreciate all you do!!

Thank you for these videos & your incredible ability to teach these concepts. I feel like I learn so much in every video I watch on your channel! You are greatly appreciated.

Hi there! I love the way you teach!! Im in the 3rd term of an accelerated program that is only 17 months. Its hard to keep up so i watch your videos more than once to get the ideas better. Thank you for making these!!

We just covered deadspace in our last vent lecture before our final this week. I understand the concepts, but working through these problems with you really helped give me a better understanding of it. I'm glad I stumbled upon this video while studying!! So thankful for your channel!

I really wish you had been my teacher once upon a time. You are great at what you do. Your such a blessing to.so many RTs. Could you please talk about base excess with ABG samples. Thanks again

Excellent explanation! I'm in an 18 month-long RT program and some of this information goes by so fast. I really appreciate your videos breaking it down.

Thank you so much, you explained deadspace in simplest way.

love you so much! Thank you for all your help!

I SO APPRECIATE your Channel. I learn so much and better understand concepts with the help of your videos! Thank you so much for everything you put into your channel! Appreciate you, your knowledge and expertise! 👏😊👍

Like pieces of a puzzle, I knew what deadspace was- at least in terms of a formula- and I knew what Ve was in terms of RR and Vt. But I didn’t know what they looked like when those “pieces” fit together. You always say: “Why > How”. Thank you for the breakdown!

Thank you so much for this video. I am about to take my test ( TMC) and you were great. I have been out of school for a while but this bring my memory.

I appreciate your clear explanation of this concept. Thank you very much!!

Thank you! So enlightening!

Thank you, Coach!

thank you and as your usual you make it simple BUT clear

THANKS FOR CLEARING MY UNDERSTANDING OF Vd to Vt ratio

Thank you again bro. You are patching in a lot of holes for me

Great info! Your videos are getting me through first semester with classes being online due to the pandemic. Thank you so much!

You are TRULY AWESOME! Your last illustration of using Ve and VD/VT helped answer a question from my summer packet! Now I have to figure out 1 more.🥳

thanks coach your lecture just answered the question: . If the rate of breathing increases without any change in total minute ventilation (VE constant): A. The alveolar ventilation per minute will increase B. The alveolar ventilation per minute will decrease C. The deadspace ventilation per minute will decrease D. The alveolar ventilation per minute will remain constant it's letter A

This is juz amazing...very well explained and made it so simple

Thank you so much for these videos

Thank you so much, you explained it beautiful! very easy to pick up were i was lost in class the other day.

Highly appreciated coach vividly understood the concept.thanks a lot more power to your channel.God bless 🙏

Thank you for this. I actually have a visual for the MD's to understand now.

Coach you summed up a lec under 20min. Thank you for your easy to understnd video's keep it up, you make studying easier. :)

Awesome vid!!!

Thank you, I especially love your visuals. #waytoteach!!

Your videos are a blessing! 1st yr student, 4 weeks in-pulling my eyelashes out trying to master these concepts. Videos are great, easy to follow, and VISUAL! love them and will be visiting often!! I will be sharing the link with my PEEPS

🙌your the best!!!

I am currently in my first semester of respiratory school and this helped me so much!!! Thank you

Hi, first year vet student here! Found this helpful to understand tidal volumes more, we haven't really practiced equations, more just applying them to respiratory diseases. I'll be searching your channel for some more help with this application!

😊 this helps so much thank you

Thank you very much!!

Thx a lot. U explained very clearly.

Thank you so much

Thank you very much!

Can you do a video about electrolytes and understanding their relationships and how they play into ABGs? Also I appreciate your videos, thank you!!!

Thank you so much 💓

Not sure if you already covered this but I can find a video on it. But could you help me with a better understanding of Oxygen Transport and the Oxygen Transport equation? Thank you so much!! You are helping me get through RT school SO much!!

Thank you

GREAT!!!!

Good afternoon, I just started my third semester and today is day 2 on learning mechanical ventilation formulas. We learned a couple, but I'm having trouble knowing what to do with ABG gas if the patient is in respiratory alkalosis?? This morning, a question on my quiz ex: " what do you do to the patient next?" I believe they mentioned something about decrease minute ventilation and added PEEP? I'm so confused about what minute ventilation has to do with respiratory alkalosis; how are we supposed to know what to do next on a patient entering the ER. I would greatly appreciate it if you could add the video link to my comment if you had made a video explaining decreased minute ventilation. Thank you so much for these videos. I've been watching your videos since day 1 of Respiratory school!!! :)

Thank you A real therapistas as always ❤️❤️ I need u to explain what do u know about CPT for vented patients, why do RT references mention CPT for spontaneous breathing pts only? While in clinic CPT is done for vented pts with collapse in cxr.

Thank you! Just finishing new grad year and this 💡 my question is when we use ARDS net protocols for covid pts (high rate/low vt for lung protection) are we doing more harm to the body as a whole? Lower effective vt = less opportunity for an already challenged oxygenation situation

Such a good video! If the alveolar minute ventilation is 3770 would you round it up to 3.8 or down to 3.7 on the vent? (astral 150) thank you

Hey there! your content is INCREDIBLY helpful! My question is not really related to this particular video, but in general, are there any values that will always stay directly proportionate to each other in all situations in terms of mechanical ventilation...or any other respiratory topics really?

I absolutely love how you break things down. I can’t say it enough. Are you able to post the formulas in steps please so that I can label them in my notes if you have time that is thanks again for all your videos. I share just about 95 % of them 🥰

Dear coach, Thank you so much for your videos. If possible please share us your school experience like how do you study, difficulties that you have faced, what made you to choose Respiratory therapy,... Eager to listen your experiences on Respiratory Therapy.

Thanks coach for the clear explanation. I just graduated, and it is a matter of time before I go to my internship, so any pointers to help me rise above being an average intern. 🙏🌹

I understood everything about this videos except the last part right after you said a normal vd/vt percentage is 30-40% and anything higher than that you are hyperventilating your patient I completely got lost after that

One more question:) Have you done a video on chest xray interpretation? Like how to interpret or identify specific markings or patterns to look for that will pinpoint specific disease processes? I hear and see "consolidation" described a lot, but there's several pulmonary disease processes with that....how do you differentiate? Is consolidation kind of an umbrella term?

Hello! Enjoy all of your videos and you have wonderful teaching methods. I'm a 5 year post grad trying to refresh all these concepts to take the board exam and your clear explanations are the most helpful!

Hi 👋 I am in the first semester of respiratory therapy and I am having problems understanding Control of Ventilation. can you make a video about that. Thanks

Thank you for your time ❤, So becuase of that we use low rate and high tidal volume in COPD Patients, it is to eliminate the Co2 ?

Do you cover techniques for conquering the clinical sims

Very liked

Hi coach, quick question: is there a situation where minute ventilation is increased but doesnt increase the tidal volume? Normally if i increase pressure support Vt and Ve simultaneously increases. Thanks!

u kept tv of 500ml 2 remove more co2,bt in ards pt if tv is 300 nd abg suggestive of respiratory acidosis can we increase tv 2 500ml?

Is there a similair formula for patients anatomical dead space, in kilograms? Pounds are not the reference value we use at my ICU in Europe. Great videos still!

I really hope I get the pleasure of meeting you some day. I need to hug you! Why can't all instructors explain material the way you do?

This is a random request, however, I want your take on an interesting scenario I was given by my instructor. A 65-year-old 5’6” 80 Kg male in impending respiratory failure secondary to severe pneumonia with history of left lung pneumonectomy. The patient is intubated with 8.0 ETT secured at 23@ teeth mark. My specific question is, how exactly would you mechanically ventilate someone with one lung? Besides the fact that this patient has pneumonia, mechanically ventilating someone with one lung has got to be a challenge, to say the least.

Do these formulas work the same on neonates?

How would this work for a 32 week baby on HFOV? Pt. Weight is 1.93 kg 16 inches long. MAP 12, HZ 12, AMP 32, I TIME 33%. THANK YOU! You are an amazing instructor 👍

Where do you get the 178 ml of dead space aprox. in the begginning ? Is it always equal to IBW in pounds ?

will the vent take into account the dead space in the vent circuit?

So lets say the patient is 5 ft and 145#, would their estimated mL be 145mL?

Math has never been my strong suit, lol. Unfortunately, when I get equation on top of equation my brain wants to immediately shut off. I'm pretty sure I understand the concepts here, I'm just nervous about remembering all these equations in a hospital setting. Thank you for the video!

I got 172# for ibw

So can we say that dead space increases in shallow breathing?

Thank you
