Apnea

Absence of breathing respiratory arrest

1

Bronchoconstriction

Constriction of the smooth muscle of the bronchi and bronchioles causing a narrowing of the air passageway

2

Bronchodilator

A drug that relaxes the smooth muscles of the bronchi and bronchioles and reverses bronchoconstriction

3

Dyspnea

Shortness of breath or perceived difficulty in breathing

4

Hypercarbia

Increased carbon dioxide levels in the blood. Also called hypercapnia

5

Hypercapnia

Increased carbon dioxide levels in the blood. Also called Hypercarbia

6

Hypoxemia

A low oxygen content in arterial blood

7

Hypoxia

A reduced oxygen delivery to the tissues

8

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

9

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

10

Respiratory arrest

Complete stoppage of breathing. Also called apnea

11

Respiratory distress

Increased respiratory effort resulting from impaired respiratory function, while title volume and respiratory rate are still adequate

12

Respiratory failure

Insufficient respiratory rate and/or tidal volume

13

Small volume nebulizer

A device that uses compressed air or oxygen to nebulize a liquid medication into a missed that a patient can inhale

14

Spacer

A chamber that is connected to the metered dose inhaler her to collect the medication until it is inhaled

15
