AsthmaAsthma is a common long-term inflammatory disease of the airways. It is characterized by variable and recurring symptoms and reduced lung function. Symptoms include episodes of wheezing, coughing, chest tightness, and shortness of breath.
AerosolAn aerosol is a suspension of fine solid particles or liquid droplets in air or another gas. Aerosols can be generated from natural or human causes. The scientific term aerosol refers to the system consisting of particles in gas, and not to the particulate matter alone.
MedicineDiagnosis, treatment, and prevention of illnessThe Doctor by Sir Luke Fildes (1891)Medicine is the science and practice of caring for patients, managing the diagnosis, prognosis, prevention, treatment and palliation of their injury or disease, while promoting their health. Medicine encompasses a variety of health care practices which evolved to maintain and restore health through the prevention and treatment of illness and infection.
Respiratory diseaseRespiratory diseases, or lung diseases, are pathological conditions affecting the organs and tissues that make gas exchange difficult in air-breathing animals. They include conditions of the respiratory tract including the trachea, bronchi, bronchioles, alveoli, pleurae, pleural cavity, the nerves and muscles of respiration.
UltrasoundUltrasound is sound with frequencies greater than 20 kilohertz. This frequency is the approximate upper audible limit of human hearing in healthy young adults. The physical principles of acoustic waves apply to any frequency range, including ultrasound. Ultrasonic devices operate with frequencies from 20 kHz up to several gigahertz. Ultrasound is used in many different fields. Ultrasonic devices are used to detect objects and measure distances.
Cystic fibrosisCystic fibrosis (CF) is a genetic disorder inherited in an autosomal recessive manner that impairs the normal clearance of mucus from the lungs, which facilitates the colonization and infection of the lungs by bacteria, notably Pseudomonas aeruginosa and Staphylococcus aureus. CF is a rare genetic disorder that affects mostly the lungs, but also the pancreas, liver, kidneys, and intestine. The hallmark feature of CF is the accumulation of thick mucus in different organs.
Compressed airCompressed air is air kept under a pressure that is greater than atmospheric pressure. Compressed air in vehicle tires and shock absorbers are commonly used for improved traction and reduced vibration. Compressed air is an important medium for the transfer of energy in industrial processes and is used for power tools such as air hammers, drills, wrenches, and others, as well as to atomize paint, to operate air cylinders for automation, and can also be used to propel vehicles.

Drug deliveryDrug delivery involves various methods and technologies designed to transport pharmaceutical compounds to their target sites helping therapeutic effect. It involves principles related to drug preparation, route of administration, site-specific targeting, metabolism, and toxicity all aimed to optimize efficacy and safety, while improving patient convenience and compliance.
English languageWest Germanic languageEnglish is a West Germanic language of the Indo-European language family that emerged in early medieval England and has since become a global lingua franca. The language is named after the Angles, one of the Germanic peoples who migrated to Britain after the end of Roman rule.
American EnglishAmerican English, sometimes called United States English or U.S. English, is the set of varieties of the English language native to the United States. English is the most widely spoken language in the U.S., as well as the common language used in government, education, and commerce in all 50 states, the District of Columbia, and in all U.S. territories except Puerto Rico. Since the late 20th century, American English has become the most influential form of English worldwide.
Chronic obstructive pulmonary diseaseChronic obstructive pulmonary disease (COPD) is a long-term lung condition that makes it progressively harder to breathe. It occurs when the airways and lung tissue become damaged, leading to reduced airflow and reduced efficiency of oxygen exchange in the lungs. COPD develops gradually over time, and while it cannot currently be cured, treatments and lifestyle changes can help control symptoms and slow disease progression.*As an Amazon Associate I earn from qualifying purchases.
