Article by : Christopher B Cooper, Worawan Sirichana, Eric V Neufeld, Michael Taylor, Xiaoyan Wang, Brett A Dolezal. Background: COPD exacerbations occur more frequently with disease progression and are associated with worse prognosis and higher healthcare expenditure. Purpose: To utilize a networked system, optimized with statistical process control (SPC), for remote patient monitoring (RPM) and […]

Article By: Alex Stenzler Respiratory Therapy Vol. 14 No. 4 n Fall 2019 Introduction Chronic Obstructive Pulmonary Disease (COPD) is a group of progressive lung diseases that obstruct airflow. It is the third leading cause of death in the United States, affecting 16 million Americans and millions more who are not aware they have the […]

Article By: Alex Stenzler, Martin Stegenga The gold standard considered by almost everyone who performs Forced Vital Capacity (FVC) spirometry measurements is, “Does the spirometer meet the ATS/ERS guidelines, and has it passed the 24 waveform tests the Task Force created in 1994”.1,2,3 Overwhelmingly, manufacturers tout their FDA clearance and the passing of the 24 […]

Article by : Christopher B Cooper, Worawan Sirichana, Eric V Neufeld, Michael Taylor, Xiaoyan Wang, Brett A Dolezal. Background: Exacerbations of chronic obstructive pulmonary disease (COPD) occur with increasing frequency as the disease progresses and account for poor health status, worse prognosis, and higher healthcare expenditure. Methods: We developed a networked system for remote physiological […]

By: Kevin McCarthy Monitoring Spirometry at Home The last several years have seen a large increase in the interest in telehealthcare. Some of this interest is driven by the lower costs of managing patients in their homes; some by the recent implementation of penalties for rehospitalization of patients after hospital discharge; and some driven by […]

Alex Stenzler The focus of this editorial may seem counter-intuitive to many. Chronic Obstructive Pulmonary Disease (COPD) is by definition a disease that obstructs the airways, which seems best monitored by frequent measurements of airflow obstruction. The tool that has been the mainstay of monitoring COPD patients at home is a spirometer and its measurements […]

Alex Stenzler While spirometry has been used to evaluate lung function for more than 200 years, the use of flow volume loops for evaluating the forced vital capacity was only first introduced by Hyatt, Schilder and Fry in 1958.1,2,3 During a forced exhalation, as the pressure in the lung increases, the pleural pressure forces pushing […]

James Martins, MSc (c), BSc, Bevin McMullin, PhD, MappSc, RRT, Chris Miller, PhD, BA, RRT Patients performing lung function tests at home have expressed concerns as to whether they need to use pulmonary function filters on their spirometers. Considering the cost of filters, it could be a barrier to performing frequent measurements. We explored the […]
