Design of piezoelectric oscillometry, accuracy in tracking time-varying impedance and implications on the frequency dependence of resistance

, 2015
Oscillometry (OS) is commonly performed by actuators that are heavy and bulky. In this thesis I designed and simulated a new single frequency OS system. This novel design used a piezoelectric bimorph actuator on resonance. To predict the performance, a

Peripheral airway function and disease burden in COPD

ERJ Open Research
Background While oscillometry appears advantageous over spirometry in detecting peripheral airway dysfunction, a feature of COPD, further research on its role in disease monitoring is needed.

Impact of obesity on pulmonary function of preschool children: an impulse oscillometry study [PDF]

Clinical and Experimental Pediatrics
Background The increasing global prevalence of obesity poses significant public health problems, as obesity exerts adverse effects on many systems and lung function. However, research on the lung function of preschool children with obesity is limited and

Forced oscillation technique and impulse oscillometry [PDF]

, 2005
Conventional methods of lung function testing provide measurements obtained during specific respiratory actions of the subject. In contrast, the forced oscillation technique (FOT) determines breathing mechanics by superimposing small external pressure ...

Oscillometry in severe asthma: the state of the art and future perspectives

, 2023
Introduction: Approximately 3-10% of people with asthma have severe asthma (SA). Patients with SA have greater impairment in daily life and much higher costs.

Diagnostic Potential of Oscillometry: A Population-based Approach

American Journal of Respiratory and Critical Care Medicine
Abstract Rationale Respiratory resistance (Rrs) and reactance (Xrs) as measured by oscillometry and their intrabreath changes have emerged as sensitive parameters for detecting early pathological impairments during tidal breathing ...
