Inspiratory Flow Using the Osmohaler

2014-08-27 03:36:08 | BioPortfolio

Summary

The OsmohalerTM is a registered device in Australia. It is used to deliver a dry powder a commercial preparation of mannitol registered as AridolTM to test if a person has irritable airways such as active asthma.

The overseas regulatory authorities need to know that people of all ages can achieve an adequate inspiratory flow through this device during a controlled deep inspiration. Adequate flow is generally regarded as greater than 30 litres per minute in children and 60 litres per minute in adults. The OsmohalerTM is a device with low resistance and is already in use in Australia to deliver mannitol. However there is a need to document inspiratory flows through the device during a controlled deep inspiration. The protocol requires subjects to perform a controlled deep inspiration from the device on three or five occasions. No substance will be inhaled.

Medical and Biotech [MESH] Definitions

Asthma attacks caused, triggered, or exacerbated by OCCUPATIONAL EXPOSURE.

Asthma attacks following a period of exercise. Usually the induced attack is short-lived and regresses spontaneously. The magnitude of postexertional airway obstruction is strongly influenced by the environment in which exercise is performed (i.e. inhalation of cold air during physical exertion markedly augments the severity of the airway obstruction; conversely, warm humid air blunts or abolishes it).

Drugs that are used to treat asthma.

A beta-adrenergic agonist used in the treatment of asthma and bronchospasms.

Adrenergic beta-2 agonist used as bronchodilator for emphysema, bronchitis and asthma.
