The partial oxygen pressure (pO2) should be high for the maximum loading of hemoglobin with the oxygen.
Hemoglobin is a quaternary protein that transports oxygen in the blood. Hemoglobin is made up of four heme subunits and an Iron atom. Blood oxygen is bound to the hemoglobin in red blood cells. One molecule of hemoglobin binds the four oxygen molecules and forms the oxyhemoglobin.
The partial pressure of the oxygen is an important factor that determines the binding affinity of oxygen to the hemoglobin. The higher the partial pressure of oxygen the more oxygen binds with the hemoglobin. The hemoglobin binds oxygen rapidly in the pulmonary capillaries of the lungs due to higher partial pressure of oxygen.

A short term exposure to stress can cause improved performance.
Parents often make the mistake that all their children have close personalities, but in truth, it is not so. For example one child may excel in sports while another boy in the family loves to read or draw and the same goes for the girls. [ There is always a leader of the pack (more than two children) and there will always be some discord, but if they are taught to communicate with each other and with their parents as far as what is right or wrong they will settle in and as they get older they will mature and most get along just fine even if they have their own individual personalities. Some families have a 'Panel' or 'Family Meeting' when there is too much discord and all sit down and discuss the problem and come to some agreement in a calm way. There should also be house rules and all the children should have chores to do around the house. ]
