Synocope is | loss of consciousness with spontaneous |
Synocope Causes | loss of cerebral oxygenation and perfusion sign of underlying condition stressfull condition |
Synocope commonm in | all age groups |
Synocope in elderly | Postural changes defecation, coughing, orthostatic hypotention |
Synocope Types | Cardiac Noncardiac Neurocardiac |
Synocope pre- Sign/ symptoms | Pallor pupil dilation diaphoresis weakness, dizziness, vertigo nausea yawing or sighing |
Synocope symptoms | unconsciousness weak, slow pulse |
Synocope treatment | remove objects Position supine with feet elevated open air-way loosen tight clothing |
Synocope unconsciousness | summon EMS bradycardia 0.6 atropine IM could seizure |
Shock | tissues use anaerobic metabolic process |
Shock stages | initial compensatory progressive refractory |
Inital Shock | first stage, cells deprived of oxygen |
compensatory Shock | body performs physiological adaptation in an attempt to overcome shock + respiration / BP - blood supply and flow to kidney w resulting oliguria( reduced urine output) |
progressive Shock | compensatory mechanism begin to fail worsen, vital organs compromised and not functioning appropriately |
refractory Shock | failure of vital organs irreversible death will occur in a few hours |
Type of shock: Hypovolemic | most common, inadequate venous return Etiologies: vomiting /diarrhea |
Type of shock: Hypovolemic symptoms | increase heart rate reduced urine output cool skin |
Type of shock: Hypovolemic treatment | arrest cause supine position contact EMS IV fluids |
Type Cardiogenic Shock: | reduction of perfusion due to decreased cardiac output |
Type Cardiogenic Shock: Etiologies | MI Cardiac arrhythmias cardiac dysfunction |
Type Cardiogenic Shock: signs and symptoms | reduction in BP w systolic below 90 mmHg fast, weak pulse cold, clammy skin cyanosis non-specific shortness |
Type Cardiogenic Shock: Treatment | supine position contact EMS ABC of CBR Monitor vital signs 02 Needs IV fluids cardiac med's needed |
Type Distributive Shock: Vasogenic shock | 3 types Anahylactic septic neurogenic |
