    Acute respiratory failure in COPD: Causes and incidence
    (Professional Guide to Diseases (Eighth Edition))

    ARF may develop in patients with COPD as a result of any condition that increases the work of breathing and decreases the respiratory drive. Such conditions include respiratory tract infection (such as bronchitis or pneumonia). The most common precipitating factor is bronchospasm, or accumulating secretions secondary to cough suppression. Other causes of ARF in COPD include:

    ❑ central nervous system (CNS) depression — head trauma or injudicious use of sedatives, opioids, tranquilizers, or oxygen (O2)

    ❑ cardiovascular disorders — myocardial infarction, heart failure, or pulmonary emboli

    ❑ airway irritants — smoke or fumes

    ❑ endocrine and metabolic disorders — myxedema or metabolic alkalosis

    ❑ thoracic abnormalities — chest trauma, pneumothorax, or thoracic or abdominal surgery.

    The incidence of ARF increases markedly with age and is especially high among people age 65 and older.

    Infant respiratory distress syndrome: Causes and incidence
    (Professional Guide to Diseases (Eighth Edition))

    Although airways and alveoli of a neonate’s respiratory system are present by 27 weeks’ gestation, the intercostal muscles are weak and the alveolar capillary system is immature. The premature neonate with IRDS develops widespread alveolar collapse due to a lack of surfactant, a lipoprotein pres-ent in alveoli and respiratory bronchioles. Surfactant lowers surface tension and helps prevent alveolar collapse. This surfactant deficiency results in widespread atelectasis, which leads to inadequate alveolar ventilation with shunting of blood through collapsed areas of lung, causing hypoxemia and acidosis.

    IRDS occurs almost exclusively in neonates born before 37 weeks’ gestation (in 60% of those born before the 28th week). The incidence is greatest in the 1,000 to 1,500 g birthweight group. Infants of diabetic mothers, those born by cesarean delivery, second-born twins, infants with perinatal asphyxia, and those delivered suddenly after antepartum hemorrhage are more commonly afflicted.

    Respiratory syncytial virus infection: Causes and incidence
    (Professional Guide to Diseases (Eighth Edition))

    The organism that causes RSV is transmitted from person to person by respiratory secretions and has an incubation period of 4 to 5 days. Antibody titers seem to indicate that few children younger than age 4 escape contracting some form of RSV, even if it's mild. In fact, RSV is the only viral disease that has its maximum impact during the first few months of life (incidence of RSV bronchiolitis peaks at age 2 months). School-age children, adolescents, and young adults with mild reinfections are probably the source of infection for infants and young children.

    This virus occurs in annual epidemics during the late winter and early spring in temperate climates and during the rainy season in the tropics. It can also be seen in immunocompromised adults, especially patients with bone marrow transplants.

    About prevalence and incidence statistics:

    The term 'prevalence' of Respiratory conditions usually refers to the estimated population of people who are managing Respiratory conditions at any given time. The term 'incidence' of Respiratory conditions refers to the annual diagnosis rate, or the number of new cases of Respiratory conditions diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.
