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

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! 💪🏽

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.

Great explanation on the magic box Joe!

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

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?

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???

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

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