Reversible causes: consider and correct Flashcards
Description of hypoxia
lack of oxygen to brain and vital organs
Diagnosis of hypoxia
Cyanosis, SpO2 <93%, PaO2 <80mmhg
Treatment of hypoxia
Exclude mechanical cause such as obstruction. Administration of high flow, high concentration of oxygen
Description of hypovolaemia
Lack of circulating blood or plasma volume
Diagnosis of hypovolaemia
Obvious blood loss, history of increased HR with decreased BP
Treatment of hypovolaemia
Administration of IV fluids and blood products. Control bleeding
Description of hypothermia
Low core body temperature <35
Description of hyperthermia
High core body temperature >40 - e.g. MH, heat stroke
Treatment of hypothermia
Rewarm patient - bear hugger, warmed IVT, heated ventilation circuit
Provide CPR until temp 30C. Defibrillation is ineffective below this - “you’re not dead until you’re warm and dead”
Treatment of hyperthermia
Active cooling
Description of hypo/hyperkalaemia
Abnormally low or high levels of potassium
Treatment of hypo/hyperkalaemia
Administration of crystalloid IV fluids and electrolyte replacement
Description of tamponade
Blood/fluid trapped and accumulation in the pericardium compressing the heart
Diagnosis of tamponade
Becks triad: muffled heart sounds, elevated CVP with neck vein distension and hypotension
Treatment of tamponade
Pericardiocentesis
