Quantification of the Impaired Cardiac Output Response to Exercise in Heart Failure: Application of a Non-Invasive Device
Heart failure cardiac output oxygen uptake exercise testing
2015/4/23
An impaired cardiac output (CO) response to exercise is a hallmark of chronic heart failure (CHF), and the degree to which CO is impaired is related to the severity of CHF and prognosis. However, prac...
NON-INVASIVE DEVICE AND METHOD FOR MEASURING THE CARDIAC OUTPUT OF A PATIENT
United States patents cardiac output respiratory system function
2014/11/28
A method and system for detecting the presence of restriction to expired airflow in humans or animals by analyzing the expired capnogram and oxygram, as well as the geometric analysis of the real-time...
Instrumentation for measuring cardiac output by direct Fick method during liquid ventilation
equipment fluorocarbon oxygenation
2009/7/16
A closed-circuit fluorocarbon oxygenation system was designed and incorporated into an existing liquid breathing system (LBS) to allow measurement of an animal's oxygen consumption during liquid venti...
Cardiac output by impedance cardiography during head-out water immersion
human immersion cardiac
2009/7/14
This study was undertaken to ascertain the suitability of impedance cardiography for qualifying cardiac output during water immersion where the electrodes were wet. The cardiac output was compared dur...
Effect of 5 bar oxygen on cardiac output and organ blood flow in conscious rats
HBO equipment hyperbaric cardiac output animal rat
2009/7/14
The distribution of cardiac output (CO) was studied in conscious rats during hyperbaric oxygen (HBO) exposure to 5 bar for 60 min. Heart rate (HR) and arterial blood pressure (ABP) were continuously r...

Air embolism sheep cerebrovascular circulation blood flow velocity cardiac output physiopathology blood pressure heart rate capnography
2009/5/18
1. The effects of cerebral arterial gas embolism on cerebral blood flow and systemic cardiovascular parameters were assessed in anaesthetized sheep. 2. Six sheep received a 2.5 mL injection of air sim...
Distribution of cardiac output in awake rats during exposure to 5 bar
hyperbaric cardiac outputtotal myocardial blood flow rat animal
2009/3/30
Previous studies have reported increased total myocardial blood flow (TMBF) after 15 min stable pressure in a normoxic O2-N2 and O2-He at 5 bar, although cardiac output (CO), heart rate (HR), and mean...
