Study Notes

Capillaries and Venules

Capillaries connect arterioles to venules, facilitating the exchange of oxygen and nutrients with tissues.

Early Signs of Intra-Abdominal Bleeding

Initial indicators include abdominal pain and distention; significant hypotension and ecchymosis appear later.

Primary Assessment Focus

During a primary assessment, severe hemorrhage, airway obstruction, and breathing patterns are prioritized. Capillary bleeding typically receives less immediate attention.

Geriatric Patient Indicators

In older adults, weakness or dizziness may signal nontraumatic internal bleeding without a history of trauma.

Understanding Hypoperfusion

Hypoperfusion, also termed shock, indicates inadequate blood flow to tissues, leading to cellular death if untreated.

Hemophilia Characteristics

Patients with hemophilia may experience spontaneous bleeding; it does not enhance clotting with aspirin.

Management of External Bleeding

Direct pressure on the wound is the first action for controlling severe external bleeding from extremities.

Gastrointestinal Bleeding Symptoms

Hematemesis (vomiting blood) is a primary symptom indicating potential gastrointestinal bleeding.

Definition of Perfusion

Perfusion refers to the circulation of blood within an organ in sufficient amounts to meet the metabolic needs of the body.

Blood Volume and Vital Signs

Significant changes in vital signs can occur after losing more than 20% of total blood volume.

Severity of Bleeding Assessment

Assessing bleeding severity includes considering clinical signs and symptoms, general appearance, and mechanism of injury; systolic blood pressure alone is insufficient.

Managing Severe Bleeding in Specific Cases

In cases of external abdominal bleeding, assisting in patient ventilations is crucial while managing external hemorrhage.

Importance of Organ Tolerance

Skeletal muscle can endure inadequate perfusion for up to 2 hours, unlike other vital organs that may sustain damage more quickly.

Actions After Direct Pressure Failure

If direct pressure doesn't stabilize severe extremity bleeding, a tourniquet should be applied proximally to the injury site.
