Respiratory Therapy - Magic Box & Total Flow

[@marceilawhite6639]

Why was I looking for how to do the magic box for my exam to understand it....Perfect timing 😊

[@RespiratoryCoach]

Timing is everything. Thanks for watching, and I hope it helped! GO BE GREAT!

You explained this so much easier, than my school instructors Thank you!

Great chalk talk coach. I always love your presentations. You know I love to teach this topic, so I thought I would add a few things. Understanding these numbers is crucial for ensuring patients receive the correct oxygen levels when using high-flow or constant FIO2 devices. Ideally, patients shouldn't have to sustain minute volumes of 15-20 lpm for too long, which equals 45-60 lpm of inspiratory flow rates. However, in certain circumstances, it can occur. Aiming to provide 60 lpm of total flow with these oxygen devices ensures coverage for all patient types and scenarios, with the range of 45-60 lpm of total flow serving as a gray area. Dividing 60 by the total parts allows for determining the appropriate flow setting to achieve the desired FIO2. It's important to note that setting the flow above 40% FIO2 may pose challenges due to decreased total flow, as many oxygen flowmeters max out at 15 lpm. In cases where the device fails to meet or exceed the patient's inspiratory flow rate, the delivered FIO2 will decrease due to room air dilution. This knowledge empowers RTs to optimize oxygen therapy and ensure patients receive the best possible care.

100% Thanks, Don, for contributing to the conversation in a positive manner. I appreciate you!

I love your videos so much man. I’m a father, work full time and go to school full time. If it wasn’t for your AWESOME videos, I’d be failing the RT program. Thank you for what you do! 💪🏽

Great explanation on the magic box Joe!

So helpful, thank you

[@RespiratoryCoach]

Thank you for watching and commenting! Glad is was helpful.

Hello! Thank you so much for coming to our class yesterday! You were extremely helpful! I know this unrelated to our specific discussion, but I’m struggling with the air to o2 ratio. I understand the magic box and how get the total flow and total parts based on the box table, but how do I know if the patient it getting the o2 they need? Especially if I only have the FiO2 to work with and not the LPMs. I know the book and my professor says we need to shoot for the pt getting 60% on average but i don’t understand how i get to that number? Like if i use 35% at 8 lpm, and i come up with a total flow of 48 lpm. How do I know that is enough or more than enough?

I’ve been fighting COPD for 10 years nighttime oxygen 2% three years started walking 3 to 4 blocks a day after dinner eating better working out feeling a lot better quit smoking cold turkey crashed can’t even walk 5 feet now without being out of breath 11 months now no change in my condition 2% night time I’m using 2% under walking conditions in the daytime when I sit and rest I’m at 92 to 93 if I walk 10 feet it goes down to 85 or 88???

[@lizayusufzai8175]

Can you show a magic box with 100% Fi02?

[@hawrasyh8529]

Hey can you please talk about High-Frequency Oscillatory Ventilation?

[@sinclair657]

Thank you

[@ebtehalali1311]

Woww!! Thank you!!

[@RespiratoryCoach]

Thank you for watching! I appreciate the kind feedback back!

[@akmonke995]

Question. Will I need a bachelors to become an RT in a few years?

[@RespiratoryCoach]

Probably not need, but you should consider getting your bachelors for future opportunities. Thanks for watching!

[@ChristianMedalla-fm2ey]

I'm in my 4th semester; is it too early to enroll? If I enroll today, how long will the validity of the subscription be?

[@RespiratoryCoach]

Nice, Christian! Once enrolled you have LIFETIME access.

Why does the CPAP start violently pulsing in the middle of the night? It hurts my ears.

[@RespiratoryCoach]

Perhaps there's a leak in the mask and the CPAP is attempting to sustain the set pressure? I'm not sure if I completely understand the question.

[@CybekCusal]

@@RespiratoryCoach no leaks in my Oscar data. It's like it's pulsing to check for collapsed airway data or something. It really hurts my inner ear drum.

[@chocknorris1353]

Awesom!
