Why is PO2 important for divers? | SCUBA 101

Jonathan explains the concept of PO2 (Oxygen partial Pressure) and how it relates to Maximum Operating Depth (MOD) of a breathing gas, and how rebreathers gain advantage by changing the percentage of oxygen in the breathing loop at different depths to maintain a more ideal PO2 and minimize the amount of nitrogen in the breathing mix. It's not as tricky as it sounds!
