25
Hypoventilation
Decreased rate or depth of air movement into the lungs
26
Hypoexmia
Deficient oxidation of blood
27
Hypoxia
An inadequate amount of oxygen available to the cells
28
Inspiration
Act of breathing in
29
Internal respiration
Exchange of oxygen and carbon dioxide between the circulating blood and tissue cells
30
Ischemia
Deficiency of blood in a particular area
31
Nasal cannula
Disposable, plastic device that delivers oxygen via two protruding prongs for insertion into the nostrils
32
Oxygenation
The process of providing cells life-sustaining oxygen
33
Perfusion
Process by which oxygenated blood passes through body tissues
34
Pulmonary ventilation
Movement of air into and out of the lungs
35
Pulse oximetry
Noninvasive technique that measures the oxygen saturation of arterial blood
36
Respiration
Gas exchange between the atmospheric air in the Alveoli and blood in the capillaries
37
Sinoarterial node SA
A mass of tissue in the upper right atrium, just below the opening of the superior vena cava, that initiates the transmission of electrical impulses, causing contraction of the heart at regular intervals; also known as pacemaker
38
Spirometer
Instrument used to measure lung capacities in volume; one type is used to encourage deep breathing
39
Sputum
Respiratory secretion expelled by coughing or clearing the throat
40
Surfactant 
Detergent like phospholipid that reduces surface tension of the fluid lining the alveoli
41
Tachypnea
Rapid rate of breathing
42
Tracheostomy
Artificial opening made in the trachea through which a tracheostomy tube is inserted
43
Ventricles
Lower chambers of the heart
44
vesicular
Normal sound of respirations heard on auscultation over peripheral lung areas
45
Wheezes
Continuous, high pitch squeak or musical sound made as air moves through narrowed or partially obstructed airway passages
46
Thoracentesis
Procedure of aspirating pleural fluid
47
Peak expiratory flow rate
Point of highest flow during forced expiration
48
Spirometry
Measures lung volume and airflow
49
Forced expiratory volume
Amount of air exhaled at specific time
50
Residual volume
Amount of air left in lungs at maximum expiration
51
Total lung capacity
Amount of air contained within the lungs at maximum inspiration
52
Capnography
This measures the amount of carbon dioxide exhaled with each breath
53
Tidal volume
Total amount of air inhaled and exhaled in one breath
54
Vital capacity
Maximum amount of air exhaled after maximum inspiration
55
Forced vital capacity
Maximum amount of air that can be forcefully exhale after a full inspiration
56
Antitussives
For non-productive cough Codeine is an example, codeine turns to morphine in the liver Not drug of choice for patient with head injury or CNS depression Contra indicated for a pregnant or lactating women, children under four Can cause dry mouth 
57
Decongestant
Oral and nasal can cause rebound congestion Do not use oral longer than one week, nasal no more than five days 
58
Antihistamine
Adverse affects drowsiness, dry mouth, epistaxes i.e. nosebleed and paradoxical excitement Warn patients not to drive until they know how the medication affects them
59
Expectorant action
Causes thinning of secretions leading to a more productive cough and dust decreased frequency of coughing. For symptomatic relief of respiratory conditions characterized by dry, nonproductive cough and in the presence of mucus in the respiratory tract
60
Mucolytics action
Increases or liquefies respiratory secretions to aid the clearing of the airways and high risk respiratory patients who are coughing up thick tenacious secretions also used to protect liver cells from being damaged during episodes of acestaminophen
