1 Major body system examination
Clinical Tips
• The initial physical examination should focus on the major body systems, namely the cardiovascular, respiratory and central nervous systems, as severe abnormalities in these systems have the potential to be rapidly fatal. This approach is somewhat different from the head-to-tail physical examination commonly performed that is only appropriate for non-emergency patients.
Cardiovascular System
All of the information obtained from this evaluation should be used to guide subsequent therapy. For example, a patient with severe hypovolaemia will require aggressive fluid administration (see Ch. 4). However a more conservative approach may need to be taken if a non-physiological heart murmur is detected during initial evaluation. The most common cause of hypoperfusion in the emergency patient is hypovolaemia (see Ch. 2). Cardiovascular abnormalities may also be seen for example with heart failure (see Ch. 31), anaemia (see Ch. 19) and systemic inflammatory response syndrome (SIRS) or sepsis.
