Lesson No. 6: HOW TO CALCULATE DURATION OF O2 CYLINDER

Another common board exam question is to determine a cylinder's duration. If you forgot how, this video is for you!
Warning! Corny tips ahead.

I learned more from you than my actual anesthesiology professor! God bless you.

[@REYNEGOKAP]

Great video

[@ems1632]

It means that the first formula without subtracting the residual value is applicable.in full tank only?

[@ManhwaRecappedPh]

Your the best sir!!it help me at calculating in our math subject!!

[@AtYourSIRvice]

I don't see the connection but glad to be of help

[@stefaniegoodwin5812]

thank you so much this helped me

[@AtYourSIRvice]

Glad it helped!

[@dtmfool789]

Thank you!

[@pakilino9635]

what tank factor you guys use in the Philippines?

[@c4turtz]

great video but what is a tank factor! can you explain what tank factor is in depth and clearly pleaseeeee?

[@ems1632]

Why you didnt use the residual value in your first problem?

How can we classify our Oxygen tank if it's H or E type?

[@AtYourSIRvice]

Generally, they're classified according to their size and capacity. H tanks are the typical bulky ones you see in the ward, while E tanks are those smaller versions we use for transporting patients over short distances.

How about computing the o2 duration using a portable ventilator on full support mode?

[@AtYourSIRvice]

This may not be applicable since ventilators deliver O2 at much higher flow rates.

[@joyvillorente7939]

@@AtYourSIRvice do we have formula for this case?

[@AtYourSIRvice]

I assume you are asking about patient transport? However, I haven't come across a formula for this kind of scenario though I am pretty sure of the following: 1. portable ventilators have different consumption rates depending on types (e.g. electric or pneumatic) and brand (e.g. LTV, Oxylog) 2. oxygen consumption can vary depending on several factors (e.g. minute volume which can be difficult to predict in a spontaneously breathing patient, total ventilator flow) 3. we do not consume 100% of the cylinder's o2 content; we replace the cylinder as soon as it reaches dangerous low levels Cheers!

[@emarquezlim9801]

Sir, paano po yung computation kapag naka high flow nasal cannula at CPAP or BIPAP? Thank you.

[@mytchtan9691]

if my calculations are correct. 1 H tank at 1L/min should last for about 4 days? my mom consumes 1 tank at 1L/min in just around 40hrs. may na miss ba po akong factor?

[@AtYourSIRvice]

Sorry for responding late. This calculation is only theoretical. There could be other factors why cylinders run out sooner than expected: 1. Possible leak in the device or cylinder port 2. You don't really consume the entire content of the tank before replacing it (not advisable) 3. The tank gauge might not be calibrated (it's not always 2200 psig)

[@kimkimkim]

Kuya, yung 50lbs po ba na tank is H type na cylinder?

[@AtYourSIRvice]

I suppose so kuya

[@johnpaulpatun-og8704]

how to check the volume of the oxygen tank?

[@AtYourSIRvice]

Look at the pressure gauge if available. Otherwise, you have to crack it and connect one.
