Which of the following conditions might an EMT suspect as a possible cause for bleeding from the nose and mouth?
(all of the above): skull fracture, high BP, sinus infection
assessment: reassessment
- 5/15 minutes - high-flow O2 for external/internal bleeding - rapid transport if hypoperfusion - document how much blood loss occurred over what period of time
without adequate perfusion:
- CNS cells die after 4-6 minutes (no ability to regenerate) - lungs survive 15-20 minutes - kidneys damaged after 45 minutes - skeletal muscle deteriorates after 2-3 hours
blood clot formation depends on:
- blood stasis - changes in blood vessel wall - blood's ability to clot (affected by disease processes/medications) ANS directs blood away from other organs to heart/brain/lungs/kidneys in an emergency
arterial bleeding
- bright red - spurts in time with pulse - doesn't clot spontaneously difficult to control
capillary bleeding
- dark red - oozes slowly
venous bleeding
- darker red (O2 poor) - flows slowly or rapidly but doesn't spurt easier to control
tourniquet precautions
- do not apply directly over a joint - make sure it is secure and tightening - never use wire, rope, belt - consider placing padding underneath - never cover with bandage - do not loosen after application
treating facial injuries:
- do not apply excessive pressure and increase pressure on the brain skull: - loosely cover bleeding site with sterile gauze pad - wrap dressing loosely around head - watch out for CSF (halo shape draining)
signs of bleeding into chest cavity:
- dyspnea - tachycardia - hemoptysis (coughing up blood) - hypotension
MOI: internal bleeding
- high-energy MOI should increase index of suspicion - result of falls, blast injuries, MVCs, penetrating trauma - assess via DCAP-BTLS
bleeding tends to stop quickly within
10 minutes
issues that affect clotting:
- movement - disease - certain medications - removal of bandages - external environment - body temperature - hemophilia (makes all injuries, no matter how trivial, life-threatening)
severe external bleeding signs:
- poor general appearance - no response to external stimuli - signs of shock - significant amount of blood loss - rapid/ongoing blood loss - inability to control bleeding - association with MOI
three components of cardiovascular system:
- pump (heart) - container (blood vessels) - fluid (blood, bodily fluids)
assessment: scene size-up
- scene safety - standard precautions (bring multiple pairs of gloves) - ensure no fluid leaking from vehicle or energized power lines at MVC - number of patients - NOI/MOI (bloody emesis vs. upturned step stool) - ALS? - spinal immobilization?
reasons for bleeding from nose/ears/mouth:

pressure dressings and/or splints
- use 4x4 gauze for small wounds and universal dressings for larger wounds - cover entire wound and stretch bandage tight enough - check for distal pulse after applying dressing
assessment: secondary assessment
- vitals (*look out for systolic < 100 mm Hg) - pain assessment - DCAP-BTLS for secondary injuries - detailed physical exam for isolated injuries - abdomen: feel all 4 quadrants - extremities: pulse, motor, sensory (PMS)
treatment of internal bleeding
-follow standard precautions -maintain airway w/ cervical spine immobilization (if needed) -administer high flow oxygen or artificial ventilation as -necessary -control all obvious external bleeding -consider pelvic compression device or splint -monitor and record patients vitals at least every 5 min -keep the patient warm -give nothing by mouth -provide prompt transport for all patients with sign an symptoms of shock
