Learn how to draw ✍️ and label Mapleson Circuits in under 2 minutes ⏱.

There are 5 things you need to start of with:
1. Bag
2. Fresh Gas Flow
3. Tubing
4. APL valve
5. Patient

From here, the pattern is:
A = 1, 2, 3, 4, 5
B (2nd letter, so swap 2, 3 around to get) = 1, 3, 2, 4, 5
C (3rd letter, so delete 3 to get) = 1, 2, 4, 5
D (4th letter, so swap 4, 2 around and insert back 3 to get) = 1, 4, 3, 2, 5
E (5th letter, so delete 1 and 4 to get) = 3, 2, 5
F = add back in 1 but leave it open = open 1, 3, 2, 5
