Final answer:
SIRS criteria may involve systemic indicators such as abnormal temperature, heart rate, respiratory rate, or white blood cell count, rather than all cardinal signs of local inflammation like redness, heat, swelling, pain, and loss of function.
Step-by-step explanation:
The question refers to the presence of cardinal signs in Systemic Inflammatory Response Syndrome (SIRS). The cardinal signs of inflammation typically include redness, heat, swelling, pain, and loss of function. However, SIRS criteria, which are used to identify a systemic inflammatory response, may not necessarily involve all these local signs of inflammation as it is a systemic condition.
SIRS can be identified by having more than one of the following clinical findings:
- A body temperature above 38°C or below 36°C
- A heart rate of more than 90 beats per minute
- Respiratory rate of more than 20 breaths per minute or arterial carbon dioxide tension (PaCO2) of less than 32 mm Hg
- Abnormal white blood cell count (WBC)
To answer the question, all cardinal signs of inflammation are not required to be present for a diagnosis of SIRS.
