Premergency First Aid, CPR and AED Manual

1 Introduction to First Aid

The stress response is characterized by a pattern of physiological activity, including changes in hormone levels and activity in the sympathetic nervous system (SNS). This is called the ‘flight or fight’ response and refers to the body’s preparation for action, as would be necessary when providing first aid in an emergency. During an emergency, the first aider may encounter some stressors. Stress reactions vary between people and situations, due to differences in personal and contextual factors. Unless you are highly trained and experienced, stress will impact the thought processes and reaction times of most people. The better your knowledge of first aid and the more you practice your skills will significantly prepare you to deal with an emergency.
