Asthma is a common long term inflammatory disease of the airways of the lungs.

It is characterized by variable and recurring symptoms, reversible airflow obstruction, and bronchospasm.

Symptoms include episodes of wheezing, coughing, chest tightness, and shortness of breath.

These episodes may occur a few times a day or a few times per week.

Depending on the person they may become worse at night or with exercise.

Chronic obstructive pulmonary disease (COPD) is a type of obstructive lung disease characterized by long-term poor airflow.

The main symptoms include shortness of breath and cough with sputum production.

COPD is a progressive disease, meaning it typically worsens over time.

Eventually everyday activities, such as walking up stairs, become difficult.

Chronic bronchitis and emphysema are older terms used for different types of COPD.

The term "chronic bronchitis" is still used to define a productive cough that is present for at least three months each year for two years.

A symptom (from Greek σύμπτωμα, "accident, misfortune, that which befalls", from συμπίπτω, "I befall", from συν- "together, with" and πίπτω, "I fall") is a departure from normal function or feeling which is noticed by a patient, reflecting the presence of an unusual state, or of a disease.

A symptom is subjective, observed by the patient, and cannot be measured directly, whereas a sign is objectively observable by others.

For example, paresthesia is a symptom (only the person experiencing it can directly observe their own tingling feeling), whereas erythema is a sign (anyone can confirm that the skin is redder than usual).

Symptoms and signs are often nonspecific, but often combinations of them are at least suggestive of certain diagnoses, helping to narrow down what may be wrong.

In other cases they are specific even to the point of being pathognomonic.

A propeller is a type of fan that transmits power by converting rotational motion into thrust.

A pressure difference is produced between the forward and rear surfaces of the airfoil-shaped blade, and a fluid (such as air or water) is accelerated behind the blade.

Propeller dynamics, like those of aircraft wings, can be modelled by either or both Bernoulli's principle and Newton's third law.

A marine propeller of this type is sometimes colloquially known as a screw propeller or screw, however there is a different class of propellers known as cycloidal propellers - they are characterized by the higher propulsive efficiency averaging 0.72 compared to the screw propellers average of 0.6 and the ability to throw thrust in any direction at any time.

Their disadvantages are higher mechanical complexity and higher cost.

Therapy (often abbreviated tx, Tx, or Tx) is the attempted remediation of a health problem, usually following a diagnosis.

In the medical field, it is usually synonymous with treatment (also abbreviated tx or Tx).

Among psychologists and other mental health professionals, including psychiatrists, psychiatric nurse practitioners, and clinical social workers, the term may refer specifically to psychotherapy (sometimes dubbed 'talking therapy').

The English word therapy comes via Latin therapīa from and literally means "curing" or "healing".
