Q

Define breathing (ventilation)

A

Also known as pulmonary respiration. Process in which lungs carry oxygen-rich air from the atmosphere to the body, and waste CO2 from the lungs to the atmosphere.

Define cilia

A

Minute hair-like structures that extend from the surface of the cell. Cilia in the trachea move particles upward to the pharynx, a mechanism called the cilia escalator.

84
Q

Chronic bronchitis

A

Inflammation of the bronchi that may be caused by smoking, air pollution, viruses, or bacteria. Sx include swelling of the mucosa, thoracodynia and a heavy, productive cough. Tx includes bronchodilators, expectorants, and steroids.

85
Q

Expectorants

A

Medications that aid in the removal of mucus to help widen air passages.

86
Q

Emphysema

A

Characterized by the decrease in elasticity of the alveoli; they will expand, but are unable to contract back to their original size, which makes it difficult to exhale. Patients with this may have a characteristic “barrel-chested” appearance. People at high risk for this are long-term smokers and those with other respiratory disorders. Sx include orthopnea and tx is similar to that of bronchitis.

87
Q

orthopnea

A

Easier breathing when sitting upright or standing erect.

88
Q

Pneumonia

A

Inflammatory condition that affects the lungs, primarily the alveoli. As inflammatory fluids collect in the alveoli, they lose their spongy texture and become consolidated, which make O2 exchange difficult. Causes include bacterial, viral, or fungal infections, and chemicals or other inhaled substances. Sx are thoracodynia, dyspnea, hemoptysis, and mucopurulent sputum.

89
Q

Define consolidated

A

Swollen and engorged.

90
Q

93
Q

Pneumocystitis pneumonia (PCP)

A

Closely associated with AIDS. Caused by normal flora becoming opportunistic when an organisms immune system begins to fail.

94
Q

A

an organism that resides in/on most people and causes no harm to a healthy individual.

95
Q

Define opportunistic

A

Descriptive term for an organism that has the potential to cause disease.

96
Q

Acute Respiratory Distress Syndrome (ARDS)

A

Condition in which the lungs no longer function effectively and threaten the life of the patient. Alveoli fill with edema from inflammation and cause them to collapse. Mechanical ventilation is usually required to save the patient’s life.

97
Q

Neonatal Respiratory Distress Syndrome (NRDS)

A

Form of respiratory distress syndrome seen in preterm infants or infants born to diabetic mothers. Caused by insufficient surfactant, which causes the alveoli to collapse and breathing to become labored. Signs/sx include cyanosis of the extremities, flared nares, tachypnea, and a characteristic grunt heard on expiration. Radiography shows a hyaline membrane, bilateral decrease in lung volume, and alveolar consolidation; also known as Hyaline Membrane Disease (HMD).

98
Q

Define surfactant

A

phospholipid substance that keeps the alveoli open.

99
Q

Cyanosis

A

100
Q

Nares

A

nostrils

101
Q

tachypnea

A

102
Q

Hyaline membrane

A

Membrane that has a ground-glass appearance.

103
Q

Lung cancer

A

Also known as bronchogenic carcinoma; is a malignancy that arises from the epithelium of the bronchi. Masses that form eventually block the alveoli and their passages. Metastasizes in a short time and is usually caused by smoking, high pollution, radiation, and asbestos. Few lung cancers are found in the early stages when cure rate is high, and prognosis for these patients is usually poor. Tx may include surgery, chemotherapy, radiation, or a combination.

104
Q

Abnormal breath sounds

A

Abnormal noises hear over the lungs and airways, commonly leading to the diagnosis or a respiratory or cardiac condition; also called adventitious breath sounds. Most common are crackles, rhonchi, stridor, and wheezes.

105
Q

Crackle

A

Intermittent sounds caused by exudates, spasms, hyperplasia, or when air enters moisture-filled alveoli; also called rales.

106
Q

Rhonchus

A

A continuous sound heard during inspiration and expiration caused by secretions in larger airways and commonly resembles snoring.

107
Q

Stridor

A

High-pitched, harsh sound caused by swelling/spasm of the larynx or obstruction of the upper airway. May be life-threatening and may need immediate intervention.

108
Q

Wheeze

A

Whistling or sighing that results from narrowing of the lumen of the respiratory passageway. Sign of asthma, croup, hay fever, obstructive emphysema, and other respiratory conditions.

109
Q

Acidosis

A

Excessive acidity in body fluids. Commonly associated with pulmonary insufficiency and consequently CO2 retention.

110
Q

Anosmia

A

Absence of the sense of smell. Usually a temporary side effect of a URI or a condition that causes intranasal swelling.

111
Q

Apnea

A

Disorder in which breathing stops repeatedly during sleep, resulting in blood deoxygenation, causing the patient to awaken gasping for air; also called sleep apnea. May occur as often as 5 min-1 hr between episodes.

112
Q

Central sleep apnea (CSA)

A

Form of sleep apnea that occurs when the brain fails to stimulate breathing muscles, causing Cheyne-Stokes respirations.

113
Q

Cheyne-Stokes respirations

A

Periodic pauses in breathing, commonly associated with heart failure.

114
Q

Obstructive Sleep Apnea (OSA)

A

Most common form of sleep apnea caused by an upper airway blockage that prevents air from getting to the lungs. Causes include enlarged adenoids/tonsils or decreased muscle tone of the soft palate. Continuous positive airway pressure (CPAP) is a ventilatory support used to keep the airways open.

115
Q

Mixed sleep apnea

A

Type of sleep apnea that occurs when CSA and OSA occur simultaneously.

116
Q

Atelectasis

A

Collapsed or airless state of the lung, may be acute or chronic, and affects all or part of the lung. Potential surgical complication, especially those of the chest due to shallow breathing to avoid pain during surgery.

117
Q

Coryza

A

Acute inflammation of the membranes of the nose; also called rhinitis. Causes include bacteria viruses, irritants, or allergens.

118

150
Q

Chest x-ray (CXR)

Radiographic test that aids in identifying lung conditions such as pneumonia, lung cancer, COPD, and pneumothorax. Other imaging tests are performed when CXR results are inconclusive.

151
Q

Computed Tomography Pulmonary Angiography (CTPA)

A

Minimally invasive imaging technique that combines CT with angiography to produce images of the pulmonary arteries. Highly sensitive and specifically used for diagnosing PEs.

152
Q

Ventilation-Perfusion (V-Q Scan)

A

Nuclear test scan that evaluates airflow (ventilation) in the lungs for evidence of blood clot in the lungs; also called a V-Q lung scan.

153
Q

Pleurectomy

A

Excision of part of the pleura, usually the parietal pleura. Helps reduce pain caused by a tumor mass or prevent the occurrence of pleural effusion, but is generally ineffective in the treatment of a malignancy of the pleura.

154
Q

Pneumonectomy

A

Excision of a lung or portion of a lung, common treatment for cancer. There are wedge resection, segmental resection, lobectomy, and pneumonectomy.
