However, in a critical setting, a patient with a normal pH, a high CO 2, and a high bicarbonate means that, although there is a high carbon dioxide level, there is metabolic compensation. As a result, one must be careful as to not artificially adjust breaths to lower the carbon dioxide.
The average reaction time is 0.1778 s for male students, 0.1950 s for female students, 0.2033 s male teachers, and 0.1878 s for female teachers (refer to the graph for the rest of the information: median, quartile, etc.).
As an integral part of the stopping sight distance, a value for the brake reaction time must be assumed. Extensive research has shown that 90% of the driving population can react in 2.5 seconds or less. The brake reaction time normally used in design, therefore, is 2.5 seconds. The distance traveled during the brake reaction time can be calculated by multiplying the vehicle's initial speed by the brake reaction time.
