Hemorrhagic Shock: Blood Marker Sequencing and Pulmonary Gas Exchange [PDF]
Diagnostics, 2023 Background: The early identification of internal hemorrhage in critically ill patients may be difficult. Besides circulatory parameters, hemoglobin and lactate concentration, metabolic acidosis and hyperglycemia serve as laboratory markers for bleeding ...

Non-invasive Measurement of Pulmonary Gas Exchange Efficiency: The Oxygen Deficit [PDF]
Frontiers in Physiology, 2021 The efficiency of pulmonary gas exchange has long been assessed using the alveolar-arterial difference in PO2, the A-aDO2, a construct developed by Richard Riley ~70years ago.

A lifetime of pulmonary gas exchange. [PDF]
Physiol Rep, 2018 Pulmonary gas exchange is the primary function of the lung, and during my lifetime, its measurement has passed through many stages. When I was born, many physiologists still believed that the lung secreted oxygen. When I was a medical student, the only way we had to recognize defective gas exchange was whether the patient was cyanosed.

Modeling Pulmonary Gas Exchange and Single-Exhalation Profiles of Carbon Monoxide [PDF]
Frontiers in Physiology, 2018 Exhaled breath carbon monoxide (eCO) is a candidate biomarker for non-invasive assessment of oxidative stress and respiratory diseases. Standard end-tidal CO analysis, however, cannot distinguish, whether eCO reflects endogenous CO production, lung ...

Journal of Respiration, 2023 Tuberculosis-related lung damage is very different. Lung ventilation disorders have been studied in patients with pulmonary tuberculosis (TB) during the active process and after treatment, but the main causes of gas exchange changes have not been ...

Pulmonary hypertension in patients with idiopathic pulmonary fibrosis - the predictive value of exercise capacity and gas exchange efficiency. [PDF]
PLoS ONE, 2013 Exercise capacity and survival of patients with IPF is potentially impaired by pulmonary hypertension. This study aims to investigate diagnostic and prognostic properties of gas exchange during exercise and lung function in IPF patients with or without ...

Pulmonary Circulation, 2020 Pulmonary hypertension is commonly associated with heart failure with preserved ejection fraction. In heart failure with preserved ejection fraction, the elevated left-sided filling pressures result in isolated post-capillary pulmonary hypertension or ...

Use of Noninvasive Gas Exchange to Track pulmonary Vascular Responses to exercise in Heart Failure
Clinical Medicine Insights: Circulatory, Respiratory and Pulmonary Medicine, 2013 We determined whether a non-invasive gas exchange based estimate of pulmonary vascular (PV) capacitance [PV CAP = stroke volume (SV) x pulmonary arterial pressure (Ppa)] (GX CAP ) tracked the PV response to exercise in heart-failure (HF) patients ...
