Lung ultrasonography is a well established, user-friendly and easy-to-use technique that can be used in the evaluation of several pathological conditions affecting the lung. Adding lung ultrasonography to traditional echocardiography provides an integrated cardiopulmonary ultrasound analysis. The simultaneous collection of information about the heart and the lungs can help physicians to investigate acute and chronic cardio-pulmonary conditions within a noninvasive, single-probe and all-in-one examination, not exposing the patient to the danger of ionizing radiation...

Centrifugal pumps are considered to be less destructive to blood elements (1) when compared to roller pumps. However, their large prime volumes render them unsuitable as arterial pumps in heart lung machine (HLM) circuitry for children. In November of 2014, the circuit at Arnold Palmer Hospital, a Biomedicus BP-50 with kinetic assist venous drainage (KAVD) and 1/4″ tubing was converted to a roller pump in the arterial position with gravity drainage. Vacuum-assisted venous drainage (VAVD) was mounted on the HLM as a backup, but not used...

This paper presents the methodology used in patient-specific calibration of a novel highly integrated model of the cardiovascular and pulmonary pathophysiology associated with Acute Respiratory Distress Syndrome (ARDS). We focus on data from previously published clinical trials on the static and dynamic cardio-pulmonary responses of three ARDS patients to changes in ventilator settings. From this data, the parameters of the integrated model were identified using an optimization-based methodology in multiple stages...

AIM: We compared the time to initiation of cardiopulmonary resuscitation (CPR) by lay responders and/or first responders alerted either via Short Message Service (SMS) or by using a mobile application-based alert system (APP). METHODS: The Ticino Registry of Cardiac Arrest collects all data about out-of-hospital cardiac arrests (OHCAs) occurring in the Canton of Ticino. At the time of a bystander's call, the EMS dispatcher sends one ambulance and alerts the first-responders network made up of police officers or fire brigade equipped with an automatic external defibrillator, the so called "traditional" first responders, and - if the scene was considered safe - lay responders as well...

OBJECTIVES: The Cardio-vascular reserve index (CVRI) had been empirically validated in diverse morbidities as a quantitative estimate of the reserve assumed by the cardiovascular reserve hypothesis. This work evaluates whether CVRI during exercise complies with the cardiovascular reserve hypothesis. DESIGN: Retrospective study based on a database of patients who underwent cardio-pulmonary exercise testing (CPX) for diverse indications. METHODS: Patient's physiological measurements were retrieved at four predefined CPX stages (rest, anaerobic threshold, peak exercise and after 2min of recovery)...

Prognosis of acute myocarditis is generally benign, but fulminant cases exist which require advanced life support devices, such as percutaneous cardio-pulmonary support (PCPS) and ventricular assist devices (VAD), and lead to fatal outcomes. The purpose of this study was to identify predictors and their values at admission which might foreshadow a fulminant course of myocarditis. Data from 138 patients (mean age 42.0 years, 79 males) with a diagnosis of acute myocarditis in the Tokyo CCU Network database from 2007 to 2009 were analyzed retrospectively...

BACKGROUND: Chest compressions are a core element of cardio-pulmonary resuscitation. Despite periodic training, real-life chest compressions have been reported to be overly shallow and/or fast, very likely affecting patient outcomes. We investigated the effect of a brief Crew Resource Management (CRM) training program on the correction rate of improperly executed chest compressions in a simulated cardiac arrest scenario. METHODS: Final-year medical students (n = 57) were randomised to receive a 10-min computer-based CRM or a control training on ethics...

BACKGROUND: Bystander first aid can improve survival following out-of-hospital cardiac arrest or trauma. Thus, providing first aid education to laypersons may lead to better outcomes. In this study, we aimed to establish the prevalence and distribution of first aid training in the populace, how often first aid skills are needed, and self-reported helping behaviour. METHODS: We conducted a telephone survey of 1000 respondents who were representative of the Norwegian population...

A restrictive transfusion strategy led us to routinely try to conduct donor-blood free open-heart surgery even in neonates. The cardio-pulmonary bypass (CPB) circuit was minimized by priming volumina at 73 ml for the smallest patients with body weight up to 2.5 kg and 85-95 ml for those with body weight of more than 2.5 kg, and by positioning the console as close as possible to operation table. Measures were applied to save blood during the procedure. Transfusion threshold of 8 g/dl hemoglobin was retained...

Pulmonary artery hypertension (PAH) is a rapidly progressive disorder, which leads to right heart failure and even death. Overactivity of the renin-angiotensin-aldosterone system (RAAS) and sympathetic nervous system accounts for the development and progression of PAH. The role of renal denervation (RDN) in different periods of PAH has not been fully elucidated. A single intraperitoneal injection of monocrotaline (MCT, 60 mg/kg) was used to induce pulmonary remodeling in male Sprague Dawley rats (n = 40). After 24-hour of MCT administration, a subset of rats underwent RDN (RDN24h, n = 10); after 2-week of MCT injection, another ten rats received RDN treatment (RDN2w, n = 10) and the left 20 rats were divided to MCT group with sham RDN operation (MCT, n = 20)...

BACKGROUND: Clinical trials have, so far, failed to establish clear beneficial outcomes of recruitment maneuvers (RMs) on patient mortality in acute respiratory distress syndrome (ARDS), and the effects of RMs on the cardiovascular system remain poorly understood. METHODS: A computational model with highly integrated pulmonary and cardiovascular systems was configured to replicate static and dynamic cardio-pulmonary data from clinical trials. Recruitment maneuvers (RMs) were executed in 23 individual in-silico patients with varying levels of ARDS severity and initial cardiac output...

This study examined the effects of peppermint essential oil (PEP) on aerobic capacity. Seven healthy participants performed a graded maximal exercise test following 10-days of ingesting either PEP or a control in a randomised cross-over design. There was no significant difference between control and PEP trials for expired gas variables (V ̇O2 peak 3.54 vs. 3.52 L/min) or performance measures (time to exhaustion 583.33 vs. 587.04 seconds). Similarly, resting cardio-pulmonary measures were also unchanged between visits...

Enlargement of the left atrium is perceived as a part of athlete's heart syndrome, despite the lack of evidence. So far, left atrial size has not been assessed in the context of exercise capacity. The hypothesis of the present study was that LA enlargement in athletes was physiological and fitness-related condition. In addition, we tried to assess the feasibility and normal values of left atrial strain parameters and their relationship with other signs of athlete's heart. The study group consisted of 114 international-level rowers (17...

Severe and critical central airway obstruction causing impaired ventilation and/or oxygenation can impose tremendous challenges on the interventional pulmonologist. Near total airway obstruction can rapidly evolve into potentially fatal complete airway occlusion during bronchoscopic airway manipulation under moderate sedation; as well as during the induction of the general anesthesia. Although there are currently interventional pulmonary procedures available to tackle the critical airway obstruction in extreme situations, cardio-pulmonary bypass should be considered prior to the intervention to maintain the adequate gas exchange during the procedure...

Cardiac involvement in systemic sarcoidosis sometimes provokes life-threatening ventricular tachyarrhythmia. Steroid administration is one of the fundamental anti-arrhythmia therapies. For an indication of steroid therapy, a definitive diagnosis of sarcoidosis is required.(1)) However, cases that are clearly suspected of cardiac sarcoidosis based on their clinical courses sometimes do not meet the current diagnostic criteria and result in the loss of an appropriate opportunity to perform steroid therapy.Here we report a case that was diagnosed as sarcoidosis by incidental biopsy of an inguinal lymph node during cardiac resuscitation for cardiac tamponade...
