Pulmonary function testing has diagnostic and therapeutic roles and helps clinicians answer some general questions about patients with lung disease. PFTs are normally performed by a pulmonary function technologist, respiratory therapist, respiratory physiologist, physiotherapist, pulmonologist, or general practitioner.
part of physical exam(or when a respiratory problem is present) A respiratory examination , or lung examination , is performed as part of a physical examination , [ 1 ] in response to respiratory symptoms such as shortness of breath , cough , or chest pain , and is often carried out with a cardiac examination .
A low PaO 2 indicates abnormal oxygenation of blood and a person is known as having hypoxemia. (Note that a low PaO 2 is not required for the person to have hypoxia as in cases of Ischemia, a lack of oxygen in tissues or organs as opposed to arterial blood.) At a P a O 2 of less than 60 mm Hg, supplemental oxygen should be administered.
Dual band respiratory inductance plethysmography can be used to describe various measures of complex respiratory patterns. The image shows waveforms and measures commonly analyzed. Respiratory rate is the number of breaths per minute. A non-specific measure of respiratory disorder. Tidal volume (Vt) is the volume inspired and expired with each ...
2 indicates that the patient's current minute ventilation (whether high or normal) is not enough to allow adequate oxygen diffusion into the blood. Therefore, the A–a gradient essentially demonstrates a high respiratory effort (low arterial PaCO 2) relative to the achieved level of oxygenation (arterial PaO 2). A high A–a gradient could ...

A medical test is a medical procedure performed to detect, diagnose, or monitor diseases, disease processes, susceptibility, or to determine a course of treatment. Medical tests such as, physical and visual exams, diagnostic imaging, genetic testing, chemical and cellular analysis, relating to clinical chemistry and molecular diagnostics, are typically performed in a medical setting.
