Chapter 16, 17, 15 (508-528) Flashcards
Hypoxemia
Decreased oxygen levels in the blood
Dyspnea
Shortness of breath or perceived difficulty in breathing
Apnea
Absence of breath; respiratory arrest
Hypoxia
The absence of sufficient oxygen in the body’s cells
Bronchoconstriction
Constriction of the smooth muscle of the bronchi and bronchioles
Bronchodilator
A drug the relaxes the smooth muscle of the bronchi and the bronchioles and reverses bronchoconstriction
Hypercarbia
Increased carbon dioxide levels in the blood
aka hypercapnia
Respiratory Distress
Increased respiratory effort resulting from impaired respiratory function
Respiratory Failure
Inadequate respiratory rate and/or tidal volume
Respiratory Arrest
Complete stoppage of breathing
Metered-dose inhaler
Device consisting of a plastic container and canister of medication that is used to form an aerosolized medication that a patient can inhale
Small-volume nebulizer
A device that uses compressed air or oxygen to nebulize a liquid medication into a mist that a patient can inhale
Spacer
A chamber that is connected to the metered-dose inhaler to collect the medication until it is inhaled
Tripod Position
A position in which the patient sits upright, leans slightly forward, and supports the body with arms in front and elbows locked. This is a position commonly found in respiratory distress.
Pulsus Paradoxus
A drop in blood pressure of more than 10 mmHg during inhalation resulting from increased pressure within the chest that suppresses the filling of the ventricles of the heart with blood
Automaticity
The ability of cells within the cardiac conductive system to generate a cardiac impulse on their own
Heart
The muscular organ that contracts to force blood into the circulatory system
Circulatory System
System composed of the heart and blood vessals
Cardiac Conduction System
Contractile and conductive tissue of the heart that generates electrical impulses and causes the heart to beat
Atria
The two upper chambers of the heart
