The normal value for the partial pressure of arterial oxygen (PaO2) irrespective of age is greater than 80 mmHg/10.6 kPa (Mellengard K, 1966, Sorbini CA et al, 1968). The normal PaO2 for a given age can be predicted from: - Seated PaO2 = 104mmHg/13.8 kPa - 0.27 x age in years ; Supine PaO2 = 104/13.8 - 0.42 x age.

As mmHg is not common in all countries, kPa is also often used as a unit of measurement. KPa stands for kilopascal and describes the pressure exerted on a surface. KPa is widely used internationally as a unit of pressure and also measures eg the tyre pressure of cars.
A pressure measured in millimetres of mercury can be converted to a kilopascals reading using the following conversion factor calculation: 1 kPa = 1000 pascals (Pa) 1 mmHg = 133.322 pascals (Pa) kPa value x 1000 Pa = mmHg value x 133.322 Pa. kPa value = mmHg value x 0.133322. To convert PO2 results from mmHg to kPa, multiply the mmHg value by 0.133.

Hb + 3 O2 = 75% saturation. Hb + 4 O2 = 100% saturation. The O2-Hb relationship is sigmoidal (or s-shaped) and not linear.

Arterial PCO2 increased steadily during anaesthesia and 60 mins after induction PaCO2 was 10.5 +/- 2.4 kPa (78.5 +/- 17.8 mmHg) in the younger horses and 9.2 +/- 1.6 kPa (68.8 +/- 11.8 mmHg) in the older horses.
