Since its introduction in the 1950s, the forced oscillation technique (FOT) and the measurement of respiratory impedance have evolved into powerful tools for the assessment of various mechanical phenomena in the mammalian lung during health and disease.
What is FOT in pulmonary function?
Since its introduction in the 1950s, the forced oscillation technique (FOT) and the measurement of respiratory impedance have evolved into powerful tools for the assessment of various mechanical phenomena in the mammalian lung during health and disease. In this review, we highlight the most recent developments in instrumentation, signal processing, and modeling relevant to FOT measurements. We demonstrate how FOT provides unparalleled information on the mechanical status of the respiratory system compared to more widely used pulmonary function tests. The concept of mechanical impedance is reviewed, as well as the various measurement techniques used to acquire such data. Emphasis is placed on the analysis of lower, physiologic frequency ranges (typically less than 10 Hz) that are most sensitive to normal physical processes as well as pathologic structural alterations. Various inverse modeling approaches used to interpret alterations in impedance are also discussed, specifically in the context of three common respiratory diseases: asthma, chronic obstructive pulmonary disease, and acute lung injury. Finally, we speculate on the potential role for FOT in the clinical arena.
How does vibration affect breathing?
Mechanical vibration of the chest-wall has been shown to modify respiratory sensation. There are several mechanisms through which intercostal vibration could increase or decrease ‘breathlessness’. The prevailing hypothesis is that vibration stimulates afferent activity from the chest-wall muscles (i.e., muscle spindles and/or Golgi tendon organs). In animals, afferent activity from respiratory muscle tendon organs inhibits the medullary inspiratory drive ( Kondo et al., 1989 ). These changes in spontaneous drive to breathe may lead to the changes in respiratory sensation. Changes in spontaneous drive to breathe during chest-wall vibration have also been demonstrated in man ( Homma, 1980 ). Chest-wall vibration reduces dyspnea stimulated by a combination of hypercapnia and an extrinsic respiratory load (e.g. Manning et al., 1991) or intrinsic load, as in patients with chronic obstructive pulmonary disease ( Cristiano and Schwartzstein, 1997 ).
Does chest wall vibration affect respiration?
These findings demonstrate that chest-wall vibration, at the amplitude and frequency utilized in studies in which vibration altered ventilatory output and sensation ( Homma, 1980, Manning et al., 1991 ), can produce oscillations of lung tissue. As the lung is vibrated, it is conceivable that vibration stimulates pulmonary receptors and such afferent activity may contribute to the effects of vibration upon respiratory control and sensation.
How does an oscillating device work?

Why is ventilator-induced lung injury important?
These types of ventilator-induced lung injuries (VILI) are especially important to prevent in our neonatal population with respiratory distress syndrome, whose premature lungs are prone to lung injuries. Reasons can include that they do not develop an adequate number of surfactant until around 35 weeks gestation.
How many breaths per minute is a high frequency wave?
Frequency is the number of breaths per minute or how fast the high frequency wave goes in. It is measured in hertz (Hz), and 1 hertz equals 60 breaths per minute. Initial settings of the frequency are usually weight-based; a premature infant will usually start at 15Hz (900BPM) and a full-term infant will usually start at 12Hz (720BPM). Frequency is rarely changed once set, but if needed to blow off CO2, we can decrease the hertz, which can make a bigger change than only changing the amplitude.
What are the three settings of ventilation?
There are three settings that control ventilation: the power, the amplitude (delta P), and the frequency. Power and amplitude are the primary control of ventilation on the oscillator, which generates tidal volume. Power and amplitude are the size of the volume of gas produced by each high-frequency wave. However, what is the difference between ...
What is an intrapulmonary ventilator?
Intrapulmonary Percussive Ventilator (IPV) (Percussionaire Corporation, Sandpoint, ID) is an aerosol machine that delivers a series of pressurized gas minibursts at rates of 100 to 225 cycles/min to the respiratory tract. Aerosolized medications can be delivered under pressure and with oscillations that vibrate the chest. In contrast to PEP and flutter, IPV allows continuous monitored positive pressure application and percussion throughout the respiratory cycle. The patient controls variables such as inspiratory time, peak pressure and delivery rates. The Percussionaire has 510 (k) status with the FDA.
What is mechanical insufflation?
Emerson Co., Cambridge, MA) (also known as In-Exsufflator, Cofflator, cough machine) is designed to inflate the lung with positive pressure and assist cough with negative pressure; it is advocated for use in patients with NMD. The published literature on the effectiveness of mechanical insufflation-exsufflation consists of review articles, case reports, retrospective analyses, and small, uncontrolled case series. In addition, published research on mechanical insufflation-exsufflation has come from a single investigator, raising questions about the generalization of findings. A Consensus Panel Report by the American College of Chest Physicians (Irwin et al, 1998) stated that " [t]he inability of patients with respiratory muscle weakness to achieve high lung volumes is likely to contribute to cough ineffectiveness. Increasing the inhaled volume prior to cough by air-stacking positive pressure breaths or by glossopharyngeal breathing increases cough expiratory flows by 80 % in these patients. Cough efficiency may be further enhanced by the application of negative pressure to the airway for a period of 1 to 3 s. Using this technique of mechanical insufflation-exsufflation, peak cough expiratory flows can be increased by more than four-fold." The Consensus Panel Report, however, concluded that " [w]hile a variety of nonpharmacologic protussive treatment modalities may improve cough mechanics, clinical studies documenting improvement in patient morbidity and mortality are lacking."
What is CHFO therapy?
Morgan and colleagues (2016) noted that continuous high -frequency oscillation (CHFO) creates a pressure gradient in the small airways that accelerates expiratory flow. The intended use of CHFO therapy is to facilitate secretion removal and treat atelectasis. These researchers evaluated the feasibility, safety, and effectiveness of CHFO in the mechanically ventilated pediatric population. After institutional review board approval, these investigators retrospectively reviewed medical records of mechanically ventilated children treated with CHFO (the MetaNeb system) at their institution from July 1, 2007 through August 31, 2012. Patients supported with extracorporeal membrane oxygenation were excluded. The authors evaluated changes in ventilator settings in subjects with ventilator data documented within 6 hours pre- and post-treatment. They evaluated arterial blood gas (ABG) results for individual treatments, comparing ABG results within 8 hours pre-therapy to ABG results within 3 hours post-treatment. Oxygen index and PaO2 /FIO2 were calculated. Demographic data, blood pressure (BP), heart rate (HR), and development of new air leak while being treated with CHFO were recorded. Pre- and post-CHFO measurements were compared using Wilcoxon signed-rank testing. This cohort included 59 invasively ventilated subjects. Median age was 2 years (range of 1 month to 19 years), and median weight was 14 kg (2 to 81 kg). These researchers evaluated data on 528 total treatments (range per subject 1 to 39 treatments). Peak inspiratory pressure significantly decreased with CHFO, whereas other parameters, including PaCO2 and breathing frequency, remained stable. There was no significant change in systolic BP, diastolic BP, or HR following treatment with CHFO. One subject (2 %) developed a clinically insignificant pneumothorax during CHFO. The authors concluded that CHFO is feasible and appears safe in this cohort of mechanically ventilated pediatric subjects. The rate of pneumothorax was consistent with that seen in similar pediatric ICU populations. They stated that these preliminary results suggested that CHFO may be beneficial by improving lung compliance in pediatric subjects with secretion-induced atelectasis; prospective clinical studies are needed to further evaluate the clinical safety and effectiveness of CHFO in children receiving invasive mechanical ventilation.
