What heart rate is considered tachycardic for infants, toddlers/preschoolers, school age/prebuscent, and adults?Infants > 160, toddlers/preschoolers > 140, school age/prepubescent > 120, andadults > 100Compensatory mechanisms may preclude a measurable fall in systolic blood pressure until up to ____% of the patient's blood volume is lost.30%What is the trauma triad of death?The trauma triad of death is the combination of hypothermia, coagulopathy, and acidosis. Severe hemorrhage in trauma diminishes oxygen delivery, and may lead to hypothermia. Hypothermia, in turn, can halt the coagulation cascade, which exacerbates the hemorrhage. Since tissues are hypoperfused, anaerobic metabolism increases, causing the release of lactic acid and other acidic compounds. Such an increase in acidity can reduce myocardial performance, further exacerbating tissue hypoperfusion. And so, the viscious cycle continues, ultimately ending in death ... unless someone trained in ATLS intervenes.A patient may be abusive and belligerent because of _____, so don't just assume it's due to drugs, alcohol, or that he is a jerk.hypoxia [Show More]
