INTRODUCTION: Pediatric cardiac arrest is an uncommon but critical life-threatening event requiring effective cardiopulmonary resuscitation. High-quality cardio-pulmonary resuscitation (CPR) is essential, but is poorly performed, even by highly skilled healthcare providers. The recently described two-thumb chest compression technique (nTTT) consists of the two thumbs directed at the angle of 90° to the chest while having the fingers fist-clenched. This technique might facilitate adequate chest-compression depth, chest-compression rate and rate of full chest-pressure relief...

Patients with coronary heart disease or acute myocardial infarction after cardiac catheterization with stenting referred for phase II cardiac rehabilitation (CR) were grouped according to their preference. Cardio-pulmonary exercise testing (CPET) was used to determine oxygen uptake ((Equation is included in full-text article.)) at peak exercise and anaerobic threshold (AT). The control patients received counseling only while the experiment group received 36 sessions of CR in 3 to 6 months. Exercise physiology parameters and serum myokines (myostatin, insulin-like growth factor-1 (IGF-1), and interleukin-6 (IL-6) were measured pre- and postrehabilitation...

INTRODUCTION: Aconite poisoning is relatively rare but is frequently complicated by ventricular dysrhythmias, which may be fatal. Molecular basis of aconite alkaloid ventricular arrhythmogenicity: Aconite exerts its toxic effects due to the presence of an admixture of alkaloids present in all parts of the plant. The major target of these aconite alkaloids is the fast voltage-gates sodium channel, where they cause persistent activation. This blockade of the channel in the activated state promotes automaticity within the ventricular myocardium and the generation of ventricular arrhythmias...

In this review of 126 publications, we report that an overwhelming majority of adults born at preterm gestations remain healthy and well. However, a small, but a significant fraction of them remain at higher risk for neurological, personality and behavioral abnormalities, cardio-pulmonary functional limitations, systemic hypertension, and metabolic syndrome compared to their term-born counterparts. The magnitude of increased risk differed across organ systems, and varied across reports. The risks were proportional to the degree of prematurity at birth and seemed to occur more frequently among preterm infants born in the final two decades of the 20(th) century and later...

BACKGROUND: Out of hospital cardiac arrest (OHCA) mortality rates remain very high with poor neurological outcome in survivors. Extracorporeal cardiopulmonary resuscitation (ECPR) is one of the treatments of refractory OHCA. This study used data from the mobile intensive care unit (MOICU) as part of the emergency medical system of Paris, and included all consecutive patients treated with ECPR (including pre-hospital ECPR) from 2011 to 2015 for the treatment of refractory OHCA, comparing two historical ECPR management strategies...

Tuberculosis is kind of common chronic infectious disease, of which the pathogenic bacterium is mainly Mycobacterium tuberculosis (MTB). One who is suffering severe tuberculosis may be ended with cardio-pulmonary function damage or cardio-pulmonary failure. This disease is of higher risks of complications or even high death rate, which is seriously challenging people's health and life. When a tuberculosis patient is accompanied with respiratory failure, which means the disease has developed into the late stage, on this occasion the optimal treatment program is to use mechanical ventilation to improve the respiratory failure condition...

BACKGROUND: Hypoxic brain injury is described in up to 40% of survivors after out-of-hospital cardiac arrest (OHCA). Besides cognitive impairments, lack of circulation may also affect exercise capacity. It is not known if exercise capacity of patients with cognitive impairments differs from other OHCA survivors. METHODS: This retrospective cohort study included patients ≥18 years with myocardial infarction (MI) as cause of OHCA admitted for cardiac rehabilitation between February 2011 and April 2014...

BACKGROUND: Providing adequate chest compression is essential during infant cardio-pulmonary-resuscitation (CPR) but was reported to be performed poor. The "new 2-thumb technique" (nTTT), which consists in using 2 thumbs directed at the angle of 90° to the chest while closing the fingers of both hands in a fist, was recently introduced. Therefore, the aim of this study was to compare 3 chest compression techniques, namely, the 2-finger-technique (TFT), the 2-thumb-technique (TTHT), and the nTTT in an randomized infant-CPR manikin setting...

The fluctuating course of tidal volume (VT), breathing frequency (DF) and minute ventilation (VE) during the cardio-pulmonary exercise test using a ramp incremental protocol occurs not only in patients, but relatively frequently also in healthy individuals. It can account for a number of irregularities in the course of the curves VO2, VCO2 and in particular of those of ventilatory equivalents for O2 and CO2 (EQO2, EQCO2) as well as curves of partial pressure of end-tidal oxygen and partial pressure of end-tidal carbon dioxide (PETO2, PETCO2), which are also used, inter alia, to establish ventilatory thresholds...

INTRODUCTION: Chest compressions depth and complete chest recoil are both important for high-quality Cardio-Pulmonary Resuscitation (CPR). It has been demonstrated that anthropometric variables affect chest compression depth, but there are no data about they could influence chest recoil. The aim of this study was to verify whether physical attributes influences chest recoil in lay rescuers. METHODS: We evaluated 1 minute of compression-only CPR performed by 333 laypersons immediately after a Basic Life Support and Automated External Defibrillation (BLS/AED) course...

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...

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...
