Study Notes
Shock and Bleeding
- Hypovolemic Shock: Occurs when the body cannot compensate for rapid blood loss, particularly after losing at least 10% of blood volume.
- Indicators in Older Patients: Weakness or dizziness may be the first sign of nontraumatic internal bleeding.
Patient Assessment
- Suspicion of Gastrointestinal Bleeding: In a patient presenting with weakness, dizziness, and low blood pressure combined with thready pulse.
- Significant Findings in Internal Bleeding: History of anticoagulant use (e.g., rivaroxaban) is critical for assessment.
Tourniquet Application
- Tourniquet Management: Should only be removed at the hospital since releasing it may cause bleeding to return.
Vital Signs and Blood Volume Loss
- Vital Changes: Significant changes are seen when more than 20% of total blood volume is lost.
- Mechanisms to Control Bleeding: The body uses clotting, coagulation, and vasoconstriction.
Abdominal Trauma
- Suspicion of Splenic Injury: Diffuse abdominal pain and referred pain to the shoulder indicate possible splenic injury post-blunt trauma.
Blood Circulation Terminology
- Perfusion: Refers to adequate blood circulation within tissues to meet oxygen and nutrient needs.
- Hypoperfusion: A condition where the circulatory system fails to provide sufficient circulation, leading to shock.
Blood Components and Injuries
- Aorta: The main artery transporting blood from the left ventricle to the body.
- Arterioles: Small branches of arteries leading into capillaries.
- Capillaries: Microscopic vessels facilitating substance exchange between blood and tissues.
Blood Disorders and Conditions
- Hemophilia: A hereditary condition resulting in a deficiency of clotting factors, leading to spontaneous bleeding.
- Contusions and Hematomas: Refers to bruising and internal bleeding under the skin.
Other Medical Terms
- Hematuria: Presence of blood in urine.
- Hemoptysis: Coughing up blood.
- Epistaxis: Nosebleed.
- Shock Definition: A life-threatening condition resulting from inadequate blood circulation due to low blood volume.
Emergencies and Treatments
- Pelvic Binder: A device used to stabilize the pelvis in cases of serious fractures to reduce hemorrhage and pain.
- Tourniquet: A critical method for controlling severe bleeding, especially in limb injuries.
