Nremt Flashcards
The medulla oblongata acts as a conduction pathway for ascending and descending nerve tracts. It controls
heart rate regulation,
blood vessel diameter,
breathing,
swallowing,
vomiting.
The mesencephalon or midbrain is the smallest region of the brainstem. It controls
hearing
visual tracking, general eye turning
autonomic functions such as motor activities and muscle tone.
the cerebrum controls
Consciousness, mood influence, and certain body movements linked to fear
The hypothalamus controls
body temperature regulation,
water balance,
sleep-cycle control,
appetite,
sexual arousal.
Rapid filling phase
when the AV valves are open and blood flows into the ventricles
Diastasis
when the pressure between the atria and ventricles begin to equalize
Atrial kick
when the atria contract and expel what little blood is in the chambers into the ventricles.
Isovolumetric relaxation
a phase in systole.
Patients suffering from the adverse effects of myxedema are suffering from thyroid hormone deficiency. These patients will likely present with
hypothermia, hypoglycemia, hypotension, respiratory depression, and coma due to the lack of circulating thyroid hormone.
Tabun, Sarin, and VX are nerve agents.
Soman is another nerve agent. Symptoms
begin immediately after exposure to all of these, and will vary in severity depending on the route of exposure, duration of contact, and amount of exposure.
Lewisite
is a vesicant, causes severe damage to skin and mucous membranes if inhaled.
Trauma lethal triad
Coagulopathy, hypothermia, acidosis
Alpha 1 receptor does what
Increased vasoconstriction to bring up blood pressure
Beta 1 receptor does what?
Increases the heart rate and contractility
Beta 2 receptor does what?
Dilates the bronchioles in the lungs
