Airway
The most common source of upper airway obstruction in an unresponsive patient
Tongue
A series of cardiac conditions that are caused by an abrupt reduction in blood flow through a coronary syndromes
Acute coronary syndromes (ACS)
Alteration in the ability to perform coordinated motions such as walking
Ataxia
The early stage of shock. The systolic blood pressure and brain perfusion are maintained
Compensated Shock
Selective beta-2 agonist that stimulates adrenergic receptors of the sympathomimetic nervous system
Albuterol
If restriction of spinal motion is unnecessary, then plane an unconscious patient in the . . .
recovery position
This phase is the longest phase of the action potential. During this phase, sodium and calcium slowly enter the cell, while potassium flows out of the cell. The presence of calcium prolongs depolarization of the membrane, creating a plateau. Contraction ends when the outward flow of potassium exceeds the inward flow of sodium and calcium.
Phase 2 aka plateau phase
An autoimmune condition in which the body attacks the myelin that insulates the brain and spinal cord, causing scarring
Multiple Sclerosis (MS)
The late stage of shock, when blood pressure is falling
Decompensated (hypotensive) Shock
Blocks sodium, potassium, and calcium channels; prolongs the action potential and repolarization; decreases AV conduction and sinoatrial (SA) node function.
Amiodarone
A variety of infections can cause swelling in the upper airway. Infection can lead to . . .
laryngotracheobronchitis
When is it okay to massage both the left and right sides of the carotid arteries simultaneously?
NEVER! Doing so may cause significant bradycardia, cerebrovascular accident, or asystole
The sudden, erratic firing of neurons; a neurologic episode caused by a surge of electric activity in the brain; can be a convulsion characterized by generalized, uncoordinated muscular activity, and may be associated with loss of consciousness
Seizure
Vomited Blood
Hematemesis
Binds to opiate receptors, producing analgesia and euphoria
Fentanyl
The 3 most common obstructive airway diseases are
1. emphysema,
2. chronic bronchitis, and
3. . .
asthma
The ___ refers to a deep S wave in lead I, a deep, narrow Q wave in lead III, and a T-wave inversion in lead III.
S1Q3T3 pattern
An interruption of blood flow to the brain that results in the loss of brain function
Stroke aka cerebrovascular accident
The final stage of shock, prior to death
Irreversible Shock
Inhibits extracellular calcium ion influx across membranes of myocardial cells and vascular smooth muscle cells, resulting in inhibition of cardiac and vascular smooth muscle contraction and thereby dilating main coronary and systemic arteries.
Diltiazem (Cardizem)
___ is a severe, prolonged asthmatic attack that cannot be stopped with conventional treatment. It is a dire medical emergency
Status asthmaticus
A disease of the heart muscle
Cardiomyopathy
Severe renal failure resulting in the buildup of waste products within the blood; eventually impairs brain function
Uremia
A condition in which volume is lost in the form of blood
Hemorrhagic Shock
Immediate metabolic precursor to norepinephrine. Produces positive inotropic and chronotropic effects
Dopamine
