Key terms, chapter 10 Flashcards
Anaphylaxis
A life threatening allergic reaction that produces shock through vasodilation and fluid shifts with the potential for asphyxia
Anatomical dead space
The amount or air left in the lung after exasperation
Gases are present, but no mechanical exchange of gases with the blood.
Apoptosis
Cell deaths caused by genetic programming of a cell to eliminate damage cells
Asphyxiation
Being deprived of oxygen
Atelectasis
Complete or partial collapse of the alveoli
Cardiomyopathy
A disorder of the heart in which the muscle is enlarged and unable to function effectively
Clinical impression
Preliminary determination of the patient’s problem based on history s/s and the EMS providers, knowledge and clinical reasoning to the problem
Compensated shock
Low blood volume, but still able to maintain a blood pressure and organ perfusion.
Blood is is pulled into the vital organs.
Decompensated shock
Low blood volume where the body is unable to maintain blood pressure or adequate perfusion to the vital organs.
Defibrillation
An electrical current through the heart to terminate VFib or pulseless VTach
Diabetic ketoacidosis (DKA)
Hyperglycemia, where a patient is dehydrated, acidic and has electrolyte imbalances
Dysrhythmia
Any irregular rhythm that does not originate from the SA node
Hemorrhagic shock
Inadequate tissue perfusion caused by blood loss
Hyperpyrexia
Oh hi fever above 41.1°C or 106°F.
Hypothermia
Body temperature is lower than normal
Hypoxia
Low blood flow to the tissue or low oxygen content in the blood
Irreversible shock
The terminal phase of shock
Ischemia
Lack of blood flow to tissues
Ischemic phase
Capillaries constrict to divert blood away from peripheral tissue and the gastrointestinal system.
Lactic acid
The chemical produced by anaerobic shock that causes acidosis
Metabolic acidosis
Decreased pH and bicarbonate levels in the blood
Pathology
The study of disease states
Pathophysiology
The study of the impact in the body’s response to the disease state
Pneumothorax
Collapse lung
A collection of air within the pleural cavity, but outside the lung
Pulmonary embolism
Blood clot in the artery of the lung
Pyruvate
Initial substance formed by anaerobic metabolism w/o oxygen converts to lactic acid. With oxygen it’s used in the Krebs cycle to produce ATP.
Respiratory arrest
Apnea
Respiratory failure
The inability to maintain adequate ventilation and oxygen
Shock
Inadequate perfusion to the tissues, to adequately mean metabolic demands
Signs
What you see?
Sodium potassium pump
Mechanism of a cell membrane that uses energy to exchange, sodium and potassium ions across the cell membrane
Stagnant phase
Blood pools in the capillary beds, collecting lactic acid and form blood clots
Sudden cardiac arrest
The heart stops beating
Symptoms
Physical or mental experiences a patient his having
Ventilation-perfusion, mismatch
Pulmonary or alveolar ventilation is impaired
Ventricle fibrillation
A lethal, cardiac dysrhythmia where the heart doesn’t contract
Ventricle tachycardia
A cardiac dysrhythmia, rapid firing of the ventricles, typically with wide QRS complex
Washout phase
Stagnant blood, lactic acid and microscopic blood clots in the capillary beds re-enter circulation
