Study Notes
Bleeding and Its Effects
- A fractured femur can lead to the loss of 1 L or more of blood into the thigh's soft tissues.
- Hypoperfusion, or shock, is another term used when the body experiences inadequate perfusion, often due to low fluid volume.
- The body's organisms can better resist damage from hypoperfusion at temperatures below 98.6°F (37.0°C).
Symptoms and Indicators
- Dizziness upon standing is an early indicator of internal bleeding in non-trauma patients.
- In older patients, weakness or dizziness may be the first sign of nontraumatic internal bleeding.
- Initial signs of intra-abdominal bleeding may include pain and distention.
- Hematemeisis, or vomiting blood, indicates possible gastrointestinal bleeding.
Types of Bleeding
- External bleeding from veins is easier to control due to their lower pressure compared to arteries.
- Intracranial bleeding can be signaled by blood from the nose following head trauma, indicative of a skull fracture.
- Internal bleeding into a fractured extremity is primarily controlled by splinting the affected limb.
Control Measures
- Most external bleeding from extremities can generally be managed by applying local direct pressure.
- The air splint is appropriate for open fractures with external bleeding.
Vital Signs and Physiological Responses
- Significant changes in vital signs occur when an adult loses more than 20% of total blood volume.
- The cardiovascular system's ability to adjust for blood loss is closely tied to the rate of bleeding.
Organ Tolerance and System Importance
- Skeletal muscle is capable of withstanding inadequate perfusion for up to 2 to 3 hours.
- The least critical body component for maintaining adequate blood flow is the spleen, which primarily filters blood cells rather than directly supplying perfusion.
Clinical Considerations
- The severity of bleeding should not be gauged solely on systolic blood pressure but must consider other signs and findings for a comprehensive evaluation.
