Replication Data for: The Two-Gasometry Indirect Fick Method for Cardiac Output Measurement in Critical Patients

Data for reproducibility of a study aiming to determine agreement and clinical interchangeability of cardiac output and cardiac index measurements from transthoracic echocardiography (reference test) and the two-gasometry indirect Fick method (index test) in critical care patients from a low-resource hospital in Querétaro, México. A total of 243 transthoracic echocardiography cardiac output measurements were performed in 81 different time points, from a total number of 52 unique participants. This study was approved by the ethics and research committee of the Health Services of the State of Queretaro, Mexico (registration number: 1616/08/09/2024).
The dataset consists of the following variables (refer to dataset dictionary for definitions of each variable): • ID number • Time point • Age in years • Sex • Weight in kilograms • Height in meters • Body surface area • Diagnosis • Comorbidities • Mean blood pressure • Heart Rate • Inotropic • Vasopressor • Hemoglobin • Serum Lactate • Inspiratory fraction of Oxygen • Hydrogen potentia • Serum bicarbonate • Base deficit • partial pressure of oxygen • partial pressure of carbon dioxide • Arterial oxygen saturation • Partial pressure of oxygen in venous blood • Venous partial pressure of CO2 • Oxygen saturation in venous blood • Alveolar oxygen pressure • Capillary oxygen content • Arterial oxygen content • Venous oxygen content • Arteriovenous oxygen difference • Oxygen extraction • Left Ventricular Outflow diameter • Area Left Ventricle Outflow • Velocity-Time integral (1) • Velocity-Time integral (2) • Velocity-Time integral (3) • Systolic Volume (1) • Systolic Volume (2) • Systolic Volume (3) • Cardiac output, TTE first determination • Cardiac output, TTE second determination • Cardiac output, TTE third determination • Cardiac output, TTE • Cardiac index, TTE first determination • Cardiac index, TTE second determination • Cardiac index, TTE third determination • Cardiac index, TTE • Cardiac output, Fick • Cardiac index, Fick • Ventilatory mode • Maximum airway pressure • Positive end-expiratory pressure • Plateu Pressure • Driving Pressure • Tidal Volume
