CPET and technology

BACKGROUND: Wrist-worn tracking devices such as the Apple Watch are becoming more integrated in health care. However, validation studies of these consumer devices remain scarce. OBJECTIVES: This study aimed to assess if mobile health technology can be used for monitoring home-based exercise in future cardiac rehabilitation programs. The purpose was to determine the accuracy of the Apple Watch in measuring heart rate (HR) and estimating energy expenditure (EE) during a cardiopulmonary exercise test (CPET) in patients with cardiovascular disease...

The use of perioperative cardiopulmonary exercise testing (CPET) to evaluate the risk of adverse perioperative events and inform the perioperative management of patients undergoing surgery has increased over the last decade. CPET provides an objective assessment of exercise capacity preoperatively and identifies the causes of exercise limitation. This information may be used to assist clinicians and patients in decisions about the most appropriate surgical and non-surgical management during the perioperative period...

Cardiopulmonary exercise testing (CPET) is a specialized subtype of exercise testing that provides a more accurate and objective measure of cardiorespiratory fitness (CRF). CPET relies on measurement of ventilatory gases during exercise, i.e., a non-invasive procedure that involves the acquisition of expired ventilation and concentrations of oxygen (O2) and carbon dioxide (CO2) during progressive exercise. The non-invasive measurement of ventilation and expired gases permits the most accurate and reproducible quantification of CRF, a grading of the etiology and severity of impairment, and an objective assessment of the response to an intervention...

Surgery is the treatment of choice in patients with a diagnosis of non-small cell lung cancer (NSCLC). A pivotal of eligibility for resection is the early stage of the disease and histopathological assessment. The performance status and comorbidities in population, predominated by elderly patients, also influence the therapeutic decisions. In some lung cancer patients COPD coexists, characterized by a decrease in lung function. Then the preoperative evaluation is particularly important, for both the risk of postoperative complications, lung function and quality of life postoperatively...

Cardiopulmonary exercise testing (CPET) provides assessment of the integrative responses involving the pulmonary, cardiovascular, and skeletal muscle systems. Application of exercise testing remains limited to children who are able to understand and cooperate with the exercise protocol. Near-infrared spectroscopy (NIRS) provides a noninvasive, continuous method to monitor regional tissue oxygenation (rSO2). Our specific aim was to predict anaerobic threshold (AT) during CPET noninvasively using two-site NIRS monitoring...

The use of cardiopulmonary exercise testing (CPET) as a preoperative risk stratification tool for a range of non-cardiopulmonary surgery is increasing. The utility of CPET in this role is dependent on the technology being able to identify accurately and reliably those patients at increased risk of perioperative events when compared with existing risk stratification tools. This article identifies and reviews systematically the current literature regarding the use of CPET as a preoperative tool for stratifying risk in major non-cardiopulmonary surgery...

Cardiopulmonary exercise testing (CPET) is an important diagnostic instrument for early detection, differential diagnosis and follow-up evaluation in pulmonary hypertension (PH). A pulmonary vasculopathy as the underlying cause for pulmonary arterial hypertension (PAH) can be detected in early stages by measuring gas exchange during exercise. There are characteristic patterns which are typically seen in patients with PAH. Regarding follow-up assessments, CPET can quantify cardiopulmonary exercise capacity in a more differentiated way than global exercise tests like the 6-minute walking distance...

Cardiopulmonary exercise testing (CPET) is a well established technique for stratifying cardiovascular risk in patients with chronic heart failure (CHF). Important prognostic variables include a reduced peak oxygen uptake which has a central use in cardiac transplant selection, and the abnormal relation between minute ventilation (VE) and carbon dioxide production (VCO(2)), often referred to as the elevated VE/VCO(2) slope. We will discuss the pathophysiology of these abnormal responses to exercise in CHF, and how these are interpreted during CPET...

The polymer polyethylene terephthalate (PET) is widely used for packaging food that will be heated or cooked in the PET container. A procedure was developed to predict the potential of PET to migrate from the container into the food. Migration experiments using crystallized polyethylene terephthalate (CPET) and corn oil were performed at 115, 146 and 176 degrees C. From these experiments diffusion coefficients were calculated for the cyclic trimer in PET. By using an Arrhenius plot to obtain the diffusion coefficient and a temperature versus time plot of a microwave susceptor-heated CPET tray, it was possible to predict migration of the cyclic trimer into corn oil under microwave conditions...
