Chapter 16 Flashcards
Bronchoconstriction
Constriction of the smooth muscle of the bronchi and bronchioles causing a narrowing of the air passageway
Apnea
Absence of breathing respiratory arrest
Bronchodilator
A drug that relaxes the smooth muscles of the bronchi and bronchioles and reverses bronchoconstriction
Dyspnea
Shortness of breath or perceived difficulty in breathing
Hypercarbia
Increased carbon dioxide levels in the blood. Also called hypercapnia
Hypercapnia
Increased carbon dioxide levels in the blood. Also called Hypercarbia
Hypoxemia
A low oxygen content in arterial blood
Hypoxia
A reduced oxygen delivery to the tissues
Metered dose inhaler
Device consisting of a plastic container and a canister of medication that is used to form and aerosolized medication that a patient can inhale
Pulsus paradoxes
A decrease in Pulse strength during inhalation, a drop in blood pressure of more than 10 mm HG during inhalation resulting from increased pressure within the chest that suppresses the filling of the ventricles of the heart with blood
Respiratory arrest
Complete stoppage of breathing. Also called apnea
Respiratory distress
Increased respiratory effort resulting from impaired respiratory function, while title volume and respiratory rate are still adequate
Respiratory failure
Insufficient respiratory rate and/or tidal volume
Small volume nebulizer
A device that uses compressed air or oxygen to nebulize a liquid medication into a missed that a patient can inhale
Spacer
A chamber that is connected to the metered dose inhaler her to collect the medication until it is inhaled
