Crepitance
Crackles are the clicking, rattling, or crackling noises that may be made by one or both lungs of a human or animal with a respiratory disease during inhalation, and occasionally during exhalation. They are usually heard only with a stethoscope ("on auscultation"). Pulmonary crackles are abnormal breath sounds that were formerly referred to as rales. ''Bilateral crackles'' refers to the presence of crackles in both lungs. Basal crackles are crackles apparently originating in or near the base of the lung. ''Bibasal crackles'', also called ''bilateral basal crackles'', are crackles heard at the bases of both the left and right lungs. Crackles are caused by the "popping open" of small airways and alveoli collapsed by fluid, exudate, or lack of aeration during expiration. Crackles can be heard in people or animals who have pneumonia, atelectasis, pulmonary fibrosis, acute bronchitis, bronchiectasis, acute respiratory distress syndrome (ARDS), interstitial lung disease or post tho ...

Acute Respiratory Distress Syndrome
Acute respiratory distress syndrome (ARDS) is a type of respiratory failure characterized by rapid onset of widespread inflammation in the lungs. Symptoms include shortness of breath (dyspnea), rapid breathing (tachypnea), and bluish skin coloration (cyanosis). For those who survive, a decreased quality of life is common. Causes may include sepsis, pancreatitis, trauma, pneumonia, and aspiration. The underlying mechanism involves diffuse injury to cells which form the barrier of the microscopic air sacs of the lungs, surfactant dysfunction, activation of the immune system, and dysfunction of the body's regulation of blood clotting. In effect, ARDS impairs the lungs' ability to exchange oxygen and carbon dioxide. Adult diagnosis is based on a PaO2/FiO2 ratio (ratio of partial pressure arterial oxygen and fraction of inspired oxygen) of less than 300 mm Hg despite a positive end-expiratory pressure (PEEP) of more than 5 cm H2O. Cardiogenic pulmonary edema, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Snore
Snoring is an abnormal respiratory sounds, breath sound caused by partially obstructed, turbulent airflow and vibration of tissues in the upper respiratory tract (e.g., uvula, soft palate, base of tongue) which occurs during sleep. It usually happens during inhalations (breathing in). Primary snoring is snoring without any associated sleep disorders and usually without any serious health effects. It is usually defined as apnea–hypopnea index score or respiratory disturbance index score less than 5 events per hour (as diagnosed with polysomnography or home sleep apnea test) and lack of Excessive daytime sleepiness, daytime sleepiness. Snoring may also be a symptom of upper airway resistance syndrome or obstructive sleep apnea (apneic snoring). In obstructive sleep apnea, snoring occurs in combination with breath holding, gasping, or choking. Classification In the International Classification of Sleep Disorders third edition (ICSD-3), snoring is listed under "Isolated symp ...
