Evaluation of pulmonary function is essential for the diagnosis and management of respiratory disease and other conditions. Various tests are available. Some, such as spirometry and pulse oximetry, are widely used in a variety of healthcare settings; others, such as those that measure diffusing capacity and static lung volumes, are performed in specialist pulmonary function laboratories. This article examines some of the pulmonary function tests available. [ABSTRACT FROM AUTHOR]

Pulse oximetry is a widely used, non-invasive technique for assessing arterial oxygenation by measuring oxygen saturation in peripheral blood vessels. It is a simple technique, but needs to be carried out with care to obtain reliable results. This article provides guidance on the safe use of pulse oximetry and identifies some of the advantages and limitations of the procedure. [ABSTRACT FROM AUTHOR]

Nebulisers are used to deliver bronchodilators and other medication in a variety of healthcare settings.
