  • Spirometric Data Quality as Assessed by Repeatabliy in COPD Exacerbations

    AJ Harrison¹, G Sowman², H Kaur-Nagra PhD², D Price³, M Brown³, P Ford MD³. Introduction Spirometry is one of the few clinical measurements that requires maximum patient eort in order to achieve acceptable and repeatable results. Obtaining valid Spirometry data from chronic obstructive pulmonary disease (COPD) patients who present to the clinic with an exacerbation can be challenging. Pharmaceutical trials are reliant on acc...

  • Vitalograph celebrates 50 years of service to primary care

    Respiratory care has come a long way since treatment for breathing obstructions involved rolling the unfortunate patient over a barrel or dangling them from a horse. What we now term ‘COPD’ was referred to in 1679, by Swiss physician Bonet, as ‘voluminous lungs’. The Italian anatomist Giovanni Morgagni used the term ‘turgid’ lungs and in 1814 British physician Charles Badham was the first person to refer to ‘catarrh’. In...

  • Spirometry in Primary Care: A Model Service Specification for Clinical Commissioning

    The role of spirometry Office spirometry is a physiological test measuring exhaled volumes of air as a function of time. It is of irreplaceable value as a test of respiratory health in the same way that ECG and BP provide important information about general cardiovascular health. Spirometry gives an objective measurement of lung mechanics to help make or exclude a diagnosis, though a diagnosis cannot be made on the basis of spirometry alone. Spirometry is recommended prima...

  • The Cost of COPD in Primary Care

    This article was first published in PrimaryCare Today In the UK the number of road deaths has fallen from 8000 per year in 1970 to 2000 per year in 2010, a very pleasing statistic. In the same period deaths from Chronic Obstructive Pulmonary Disease (COPD) fell from 60,000 per year to 54,000 per year, not good, perhaps shocking. This statistic masks the fact that there has been a marked decrease in COPD deaths in men and a marked increase in w...

  • Inhaler Choice & Validation

    This article was first published in PrimaryCare Today on July 2012 The importance of good inhalation technique For a medication to work it has to be taken effectively by the patient. This sounds obvious and simple, but for practitioners prescribing inhalers it is not as simple as writing out a prescription. Evidence shows that many patients continue to suffer symptoms unnecessarily and that poor inhaler ...

  • New 2011 COPD Guidelines

    This article was first published in PrimaryCare Today on November 2011 Chronic Obstructive Pulmonary Disease (COPD) disease is the 5th biggest killer in the UK, causing more deaths than cancer of the bowel, breast or prostate. An estimated 3 million people in the UK have COPD, although only an estimated 1.5% of the population have been correctly diagnosed. Worldwide, COPD is the third leading cause of death and kills on average one person every 10 seconds. ...

  • Lung Health Through the Ages

    This article was first published in PrimaryCare Today on August 2011 Forms of spirometers were used long before the concept of 'science' when such things were the realm of philosophers . As early as around 150 A.D. Greek philosopher Claudius Galen, a physician, was recorded as experimenting on human ventilation by getting a child to breathe in and out of a bladder. In 1681, Giovanni Alfonso Borellii measured the volume of air inspired by sucking a li...

  • Hygiene Considerations for Spirometry

    This article was first published in PrimaryCare Today on February 2011 Synopsis Everyone performing spirometry testing knows that a new mouthpiece should be used for each new test subject, but that is not the end of spirometer hygiene procedures. This article details the hygiene reason for a defined interval between spirometry testing, guidelines for routine cleaning and disinfection, suggests procedures in the event of contamination, the Primary...

  • Differentiating Asthma from COPD

    Whilst asthma and COPD are different diseases they cause similar symptoms, which can present a challenge in identifying which of the two diseases a patient is suffering from. A patient survey by the British Lung Foundation (BLF) showed that nearly 39% of COPD patients had been told they have asthma. There are, however, some important distinctions between asthma and COPD. COPD causes chronic symptoms and narrowed airways which do not respond to treatment to op...
