Noninvasive assessment of asthma severity using pulse oximeter plethysmograph estimate of pulsus paradoxus physiology [PDF]
BMC Pulmonary Medicine, 2010 Background Pulsus paradoxus estimated by dynamic change in area under the oximeter plethysmograph waveform (PEP) might provide a measure of acute asthma severity.

Estimation of airway obstruction using oximeter plethysmograph waveform data [PDF]
Respiratory Research, 2005 Background Validated measures to assess the severity of airway obstruction in patients with obstructive airway disease are limited. Changes in the pulse oximeter plethysmograph waveform represent fluctuations in arterial flow.

Plethysmograph training: A refinement for collection of respiration data in mice [PDF]
Animal Models and Experimental Medicine, 2023 Inhaled chemicals can harm the airways. Different effects can result in distinct changes in respiratory patterns; the type of change indicates where and how the respiratory system is affected.

Bayesian Model Search for Nonstationary Periodic Time Series [PDF]
Journal of the American Statistical Association, T&M, 2019, 2018 We propose a novel Bayesian methodology for analyzing nonstationary time series that exhibit oscillatory behaviour. We approximate the time series using a piecewise oscillatory model with unknown periodicities, where our goal is to estimate the change-points while simultaneously identifying the potentially changing periodicities in the data.

Delineation of Raw Plethysmograph using Wavelets for Mobile based Pulse Oximeters [PDF]
arXiv, 2010 The non-invasive pulse-oximeter is a crucial parameter in continuous monitoring systems. It plays a vital role from admission of the patient to surgeries with general anaesthesia. The paper proposes the application of wavelet transform to delineate the raw plethysmograph signals obtained from basic portable and mobile-powered electronic hardware.
