Vagal Integration of Cardiopulmonary Regulation
Cardiopulmonary control relies on local and central integration of sensory inputs and reflex efferent signaling. Heart and lung sensors, integrators, and effectors are routinely studied in a reductionist manner to elucidate molecular mechanisms. This is accompanied by a need to explore mechanisms …

The Relationship of Resting Cardiopulmonary Function to Peak and Submaximal Cardiopulmonary Exercise Testing in Older Adults with Heart Failure
Background: Heart failure (HF) is a challenging disease that affects more than five million people, half of whom are at least 75 years old. Peak oxygen consumption (VO2peak), the minute ventilation/carbon dioxide production (VE/VCO2) slope, and the 6MWT are powerful prognostic indicators of …

Extending Function and Applications of Isolated Cardiopulmonary Systems
The use of isolated mammalian hearts has a history that is responsible for a staggering amount of the basic physiological knowledge we have about the cardiovascular system and is a primary gateway between ideas and clinical treatment. Advances in cardiac physiology, surgery, transplantation, …

Tomographic ventilation-perfusion lung scintigraphy in cardiopulmonary disease
… and perfusion in the lungs. There are many cardiopulmonary diseases, such as pulmonary embolism (PE), chronic obstructive pulmonary disease (COPD) and left heart failure (LHF), which can affect respiration negatively. The diagnosis of PE, COPD and LHF follows separate diagnostic pathways. …

Cardiopulmonary analysis of habituation to simulated kayak ergometry
… period, physiological variables which indicate cardiopulmonary demand typically will change. In general, such changes are expected with devices that require complex movements. The influence of this habituation on physical performance is vital for establishing research methodology in which …

Biocompatible circuits : inflammation and soluble adhesion molecules after cardiopulmonary bypass
… common post-operative complications following cardiopulmonary bypass (CPB) are neurocognitive deficits (NCD) and atrial fibrillation (AF). Both morbidities have been linked to inflammation resulting from surgery, anesthesia and CPB. Microemboli, inadequate oxygen delivery and the inflammatory …

A data mining approach for acoustic diagnosis of cardiopulmonary disease
Variations in training and individual doctor's listening skills make diagnosing a patient via stethoscope based auscultation problematic. Doctors have now turned to more advanced devices such as x-rays and computed tomography (CT) scans to make diagnoses. However, recent advances in lung sound …

A monitoring and display system for a cardiopulmonary bypass loop
… monitoring and display system for a cardiopulmonary bypass loop is discussed. Analog signals representing blood temperature and oxygen saturation of sample points entering and leaving the blood oxygenator, patient temperature, oxygenator heat exchanger water temperature and hemoglobin …

Design of a patient monitoring system for cardiopulmonary bypass surgery
A patient monitoring system for cardiopulmonary bypass surgery has been developed. This monitoring system uses a SWAN 286-10 computer (fully IBM PC/AT compatible) and a DT280l-A Input/Output board to monitor seven surgical parameters. This system monitors six temperatures, the hemoglobin content, …

Modelling cardiopulmonary interactions. Towards anatomically detailed and physiologically accurate cardiorespiratory models
… and physiologically accurate descriptions of cardiopulmonary interactions. We first assess the impact of cardiopulmonary mechanical interactions on system haemodynamics, validating our results against patient data published in the literature, and assessing their robustness by means of a local …

Relationship between cardiopulmonary resuscitation (CPR) knowledge, professional attitude, and job performance
현대사회는 경제성장과 서구화에 따른 변화된 생활양식과 식생활 등으로 심혈관 질환의 급격한 증가와 인구 구조의 노령화는 급사 환자의 발생률이 상승하고 있으며, 심정지가 발생했을 때 조기에 조직으로 산소를 공급하는 것이 환자의 소생에 매우 중요한 일이다. 간호사는 병원 내에서 응급상황 시 최초 발견자가 되기 쉬우므로, 응급환자의 생명을 구하는데 있어서 최고의 안전성을 확보하기 위해 적극적으로 심폐소생술을 실시하도록 하기 위한 방안을 마련하여야 하며, 이를 위해서는 병동 간호사가 심폐소생술에 대한 지식이 어느 정도 수준에 있으며, 태도 …

Changes in the clotting viscoelasticity caused by cardiopulmonary bypass (CPB) surgery
One to three percent of the Open Heart Surgery procedures have abnormal bleeding due to acquired platelet dysfunction. Standard clotting tests to determine the cause of bleeding usually take between 25 and 60 minutes to get results. This time frame is not useful for deciding what type of treatment …

The Impact of Physiotherapy on Cardiopulmonary Function in Post Covid-19 Patients
… of COVID-19 survivors have left behind chronic cardiopulmonary dysfunction, which manifests as fatigue, dyspnoea, decreased exercise tolerance, and decreased lung capacity. A key non-invasive rehabilitation technique in the absence of many pharmaceutical alternatives is physical therapy. In this …

Cardiopulmonary Predicators of Dysfunctional Ventilator Weaning Response after Coronary Artery Bypass Graft
… revealed that there is an association between cardiopulmonary indicators (CPI) and DVWR after CABG surgery. Cardiopulmonary indicators are the selected hemodynamic parameters that have an association with DVWR. The association of CPI with DVWR may be used to predict DVWR. Therefore, this study …

A prospective study on the outcomes on adult cardiopulmonary resuscitation in Cape Town
Outcomes of cardiac arrest and cardiopulmonary resuscitation (CPR) are poorly monitored or evaluated in our hospitals in South Africa. CPR plays a significant role in emergency medicine, and regardless of poor outcomes internationally, efforts should continuously be made to improve these outcomes. …
