In this video we look at Fowler's method for determining anatomical dead space. This is the third of three videos which provide an introduction to the topic of dead space as relevant for the FRCA.
For a more detailed description of this topic, please take a look at these fantastic books:

Thanks a lot for your videos! My respiratory physiology class is a total nightmare and you helped very much to understand this concept

Thank u sm sir , but there is something that I didn’t get … from where does the N2 came ?

Nitrogen is present throughout lungs during the respiratory cycle (assuming the patient is breathing air). At the start of the test, a single breath of 100% oxygen is taken. When the patient starts to exhale, it will be gas from the anatomical dead space which leaves first. This hasn't mixed with any of the existing gas within the lungs (by definition) and so contains no nitrogen. As exhalation continues, we begin to see a contribution from the non-dead space volume. This contains nitrogen from breathing air BEFORE the single breath of 100% oxygen was taken. Hope that helps

Great video! Many thanks for that! I am currently working my way through West's Respiratory Physiology followed by Pathophysiology as an anesthesia resident and am really impressed with the didactic clarity. Do you know of any comparable works for cardiovascular physiology and pathophysiology? Best regards from Germany!

This is a wonderful book by Chambers which formed the basis of my revision for the FRCA. www.cambridgebookshop.co.uk/products/basic-physiology-for-anaesthetists?variant=42184468857071&currency=GBP&gad_source=1
