31. The " balance " between condensation and evaporation gives the quantity called vapor partial pressure . 32. The deeper depth, called the " contingency depth ", is reached when the partial pressure reaches. 33. Methods used include batch mixing by partial pressure or by mass fraction, and continuous blending processes. 34. The hypoxic episode is necessarily severe, usually with an arterial oxygen partial pressure less than 40mmHg. 35. They estimate that the partial pressure of N 2 needs to be greater than 300 mbar. 36. For gases, the activity is the effective partial pressure , and is usually referred to as fugacity. 37. The partial pressure of a gas is a measure of thermodynamic activity of the gas's molecules. 38. In healthy individuals, the difference between arterial blood and expired gas partial pressures is very small. 39. Non-linear cells do not perform in an expected manner across its range of oxygen partial pressures . 40. Oxygen partial pressure in a passive addition system is controlled by the breathing rate of the diver.
