Respiratory Therapy - High Flow Nasal Cannula (HFNC)

[@timhoover5233]

Hey there! Thanks for the HFNC vid!

[@magedali4081]

Waiting for next video from practical point of view

[@TangibleReads]

Great quick video. Def want see next one.

We are used to think that CO2 is eliminated by directly affecting TIDAL VOLIUME by PRESSURE SUPPORT or HIGH RESPIRATORY RATE. Maybe using CPAP also reduces CO2? The flow of CPAP can be relatively high too.

YOU ARE AWESOME!!!!!!!!!

Does the size of patient nares and size of cannula have an effect on the amount of potential PEEP? If the cannula only occludes 75% of the nares would you still receive one centimeter of peep per 10 L of flow. 2cm of PEEP per 20 L of flow, etc

Hi Mark! The recommended size for the cannula to the nare size is approximately 50%. I'm not sure what the evidence states regarding more than the recommended cannula:nare size ratio and the associated affects regarding PEEP and dead space washout. It seems like the larger the space occupied by the cannula would increase generated PEEP, but potentially decrease dead space washout. Great question! Maybe another viewer can speak to evidence regarding this question.

Thanks coach. Another thought…. Does it matter if the patient is neonatal or adult concerning PEEP with HFNC

How is the PEEP created?

[@ilyanoselovich2030]

PEEP is PRESSURE. PRESSURE CREATED BY THE FLOW OF AIR. IT FILLS THE SPACE OF RESPIRATORY WAYS AND THE LUNGS. PEEP during CPAP it's a constant positive pressure during inspirium and expirium. PEEP during BPAP it's a positive pressure during expirium only. During inspirium there is a higher positive pressure that is called IPAP. it includes PEEP + PRESSURE SUPPORT. Two levels of positive pressure. A higher one during inspirium and lower one during expirium. .

Hi I love your videos . Can you make a video on O2 devices and oxygen delivery . I can’t seem to understand their flow rates and Fio2 . Pleaaaassse 😭😭😭❤️
