Purpose During rapid exposure to hypobaric hypoxia (HH), arterial oxygen tension and haemoglobin oxygen saturation decrease. The oxygen dissociation curve (ODC) describes the relationship of oxygen tension and haemoglobin oxygen saturation. Previous methods for ODC determination are mostly limited to standard conditions (40 mmHg PCO 2 , 37 °C), and measurements of 2,3-bisphosphoglycerate (2,3-BPG) and adenosine triphosphate (A...

To better understand the consequences of stress in realistic scenarios, police cadets were tasked with performing a police intervention under differing expectations. One group was led to anticipate a dangerous mission, while the other expected a routine event. In the field, however, both groups faced the same challenging situation. The warned group exhibited strong pre-intervention stress responses, which was minimal in the ot...
