Impulse Oscillometry: An Alternative or Supplement to Spirometry
As clinicians, should we be performing spirometry with impulse oscillometry or should we perform IOS as a replacement for spirometry?
Review the IOS technique and the values generated during testing, describe the application of IOS in evaluation of patients with dyspnea and understand the basics of IOS interpretation in conjunction with spirometry.
Whereas spirometry requires maximal respiratory effort by the patient and can, even in the most motivated patients, result in data with low or no clinical value, in contrast IOS is effort independent and minimally intrusive, requiring spontaneous normal tidal breathing by the patient.1
Multiple studies over many years show IOS has much greater sensitivity than spirometry to detect peripheral airways obstruction. Our growing understanding of the complexity of COPD or asthma warrants the adoption of strategies capable of assessing both the large and small airways, as well as measurement application that more closely matches tidal breathing.2
