Volumetric Capnography as a Screening Test for Pulmonary Embolism in the Emergency Department

Chest, 2004
To compare the diagnostic performance of volumetric capnography (VCap), which is the plot of the expired CO(2) partial pressure against the expired volume during a single breath, with the PaCO(2) to end-tidal CO(2) (EtCO(2)) gradient, in the case of suspected pulmonary embolism (PE).Single-center, prospective study.Emergency department of a teaching ...

Validation of Bohr dead space measured by volumetric capnography

Intensive Care Medicine, 2011
Bohr's dead space (VD(Bohr)) is commonly calculated using end-tidal CO(2) instead of the true alveolar partial pressure of CO(2) (PACO(2)). The aim of this work was to validate VD(Bohr) using PACO(2) derived from volumetric capnography (VC) against VD(Bohr) with PACO(2) values obtained from the standard alveolar air formula.Expired gases of seven lung ...

Different Approaches to the Analysis of Volumetric Capnography

2009
Lung mechanics and arterial blood gases are the two most common categories of variables used to assess lung function and to adjust mechanical ventilation. Analyzing the kinetics of carbon dioxide (CO2) is another attractive approach to monitor patients receiving mechanical ventilation.

Volumetric capnography in distinct phenotypes of COPD patients

4.1 Clinical Physiology, Exercise and Functional Imaging, 2016
Background: Computed tomography (CT) allows phenotyping of COPD patients, but its relationship with functional features are unclear. Volumetric capnography (VC) uses the principle of gas washout and analyzes the pattern of CO2 elimination as a function of expired volume.

Time and Volumetric Capnography

2013
The applications of time and volumetric capnography continue to grow. This chapter provides a brief history of the measurements and makes the case for both time and volumetric capnography in terms of patient safety and as an important clinical tool in the acute care setting.

Volumetric capnography to exclude pulmonary embolism at the emergency room

4.3 Pulmonary Circulation and Pulmonary Vascular Disease, 2015
Pulmonary embolism (PE) is a potentially lethal pathology which is hard to exclude without expensive imaging techniques. Recent literature suggests the use of end-tidal PCO2 (PETCO2) as a useful parameter to exclude PE. Analysis of the entire curve of the PCO2 in expired air (volumetric capnography, VCap), contains more information. VCap was performed

Volumetric Capnography for Monitoring Lung Function during Mechanical Ventilation

2006
Capnography has become standard of care in monitoring respiratory function during anesthesia [1] and together with pulse oximetry has contributed to a major improvement in safety and reduction in morbidity over the last three decades [2].

Volumetric capnography for assessing ventilation inhomogeneity in infants with BPD

European Respiratory Journal, 2013
Background: Bronchopulmonary dysplasia (BPD) is characterized by structural lung changes which may affect ventilation distribution. Volumetric capnography (VC) has been used in adults to provide information on ventilation homogeneity and ventilation-over-perfusion status.
