What is stroke volume
Stroke volume is the amount of blood ejected from the heart in one minute. The average stroke volume for an adult is 70 to 80 mL per beat. The average heart rate for an adult is 60 to 100 beats per minute.
What is cardiac output
Cardiac output is the estimation of the amount of blood pumped by the heart in one minute. It is found by multiplying stroke volume (in mL per beat) and heart rate (in beats per minute).
A fracture of the tibia or fibula may occur at any place between
the knee and the ankle. Often, both bones are fractured at the same time. Open fractures are more common with the tibia, as this bone is just beneath the skin.
general guidelines for transport of a cardiac patient during resuscitation/defibrillation efforts include the following:
if the return of spontaneous circulation (ROSC) occurs
if six to nine shocks have been delivered and the patient remains in cardiac arrest
if the AED gives three consecutive
“no shock advised” messages that are separated by five cycles (two minutes) of CPR
Opiate/opioid or narcotic (e.g., morphine, codeine, oxycodone, methadone, heroin) overdoses typically present with
hypoventilation/respiratory arrest, hypotension, pinpoint/constricted pupils, and sedation/ coma,
Anticholinergic and antihistamine (e.g., diphenhydramine, atropine, chlorpheniramine, doxylamine) overdoses will cause
tachycardia, hypertension, hyperthermia, dilated pupils, dry skin/ mucous membranes, decreased bowel sounds, and sedation/coma.
Sympathomimetic (e.g., epinephrine, albuterol, cocaine, methamphetamine)
overdose will cause
tachycardia, hypertension, hyperthermia, dilated pupils, and agitation or seizures.
Benzodiazepine (e.g., diazepam, secobarbital, flunitrazepam, midazolam)
overdose will cause
hypoventilation, hypotension, slurred speech, and sedation/ coma.
