OBJECTIVE: Cardiopulmonary resuscitation (CPR) training can improve performance during simulated cardiac arrest; however, retention of skills after training remains uncertain. Recently, hands-only CPR has been shown to be as effective as conventional CPR. The purpose of this study is to compare the retention rate of CPR skills in laypersons after hands-only or conventional CPR training. METHODS: Participants were randomly assigned to 1 of 2 CPR training methods: 80 minutes of hands-only CPR training or 180 minutes of conventional CPR training...

The thyroid and parathyroid glands are dually innervated by sympathetic (cervical sympathetic trunk [CST]) and parasympathetic (superior laryngeal nerve [SLN]) nerve fibers. We examined the effects of electrical stimulation of efferent or afferent nerve fibers innervating the thyroid and parathyroid glands on the secretion of immunoreactive calcitonin (iCT), parathyroid hormone (iPTH), 3,3',5-triiodothyronine (iT3), and thyroxine (iT4) from the thyroid and parathyroid glands. In anesthetized and artificially ventilated rats, thyroid venous blood was collected...

The adverse effects of mechanical ventilation in acute respiratory distress syndrome (ARDS) arise from two main causes: unphysiological increases of transpulmonary pressure and unphysiological increases/decreases of pleural pressure during positive or negative pressure ventilation. The transpulmonary pressure-related side effects primarily account for ventilator-induced lung injury (VILI) while the pleural pressure-related side effects primarily account for hemodynamic alterations. The changes of transpulmonary pressure and pleural pressure resulting from a given applied driving pressure depend on the relative elastances of the lung and chest wall...

BACKGROUND: To investigate the impact of dysphagia in Perry syndrome (PS), an autosomal dominant parkinsonism caused by mutation of DCTN1, which is associated with hypoventilation, depression, and weight loss. CASE PRESENTATION: We used tongue pressure measurements and manofluorography to investigate swallowing function in 2 patients with PS. Case 1, a 60-year-old male showing parkinsonism, and case 2, a 49-year-old male admitted with pneumonia, were diagnosed as having PS based on the DCTN1 gene analysis...

Evidence indicates that CO2/H(+)-evoked ATP released from retrotrapezoid nucleus (RTN) astrocytes modulates the activity of CO2-sensitive neurons. RTN astrocytes also sense H+ by inhibition of Kir4.1 channels; however, the relevance of this pH-sensitive current remains unclear since ATP release appears to involve CO2-dependent gating of connexin 26 hemichannels. Considering that depolarization mediated by H(+) inhibition of Kir4.1 channels is expected to increase sodium bicarbonate cotransporter (NBC) conductance and favor Ca(2+) influx via the sodium calcium exchanger (NCX), we hypothesize that depolarization in the presence of CO2 is sufficient to facilitate ATP release and enhance respiratory output...

One of the most important topics that occupy public health problems is the air quality. That is the reason why mechanical ventilation and air handling units (AHU) were imposed by the different governments in the collective or individual buildings. Many buildings create an artificial climate using heating, ventilation, and air-conditioning systems. Among the existing aerosols in the indoor air, we can distinguish the bioaerosol with biological nature such as bacteria, viruses, and fungi. Respiratory viral infections are a major public health issue because they are usually highly infective...

Various forms of high-frequency ventilation (HFV) have been described. HFV is broadly defined as artificial ventilation of the lungs with sub-deadspace tidal volumes delivered using supra-physiological frequencies. HFV has been used in anaesthesia and intensive care for special procedures and conditions since the 1960s. Clinical interest in the use and the technical evolution of HFV has developed over time. There is a renewed interest in HFV for avoiding parenchymal movement during stereotactic tumour ablation...

Extracorporeal Membrane Oxygenation (ECMO) has become well established technique of the treatment of severe acute respiratory failure (Veno-Venous ECMO) or circulatory failure (Veno-Arterial ECMO) which enables effective blood oxygenation and carbon dioxide removal for several weeks. Veno-Venous ECMO (V-V ECMO ) is a lifesaving treatment of patients in whom severe ARDS makes artificial lung ventilation unlikely to provide satisfactory blood oxygenation for preventing further vital organs damage and progression to death...

A newly developed Korean-Advance Directive (K-AD) consists of a value statement, treatment directives, and proxy appointment. It remains undetermined whether K-AD is applicable to community-dwelling persons (≥ aged 60 years). Using a descriptive study design, 275 elderly persons completed the K-AD (mean age = 77.28 ± 8.24 years). The most frequent value at the end of life was comfort dying, followed by no burden to family (23.6%). Among 4 K-AD treatment options, more than half had a preference for hospice care and had reluctance with aggressive treatment choices of cardiopulmonary resuscitation (76...

BACKGROUND: The efficacy of opioid administration to reduce postoperative pain is limited by respiratory depression. We investigated whether clinically relevant opioid concentrations altered the respiratory pattern in the parabrachial nucleus, a pontine region contributing to respiratory pattern generation, and compared these effects with a medullary respiratory site, the pre-Bötzinger complex. METHODS: Studies were performed in 40 young and 55 adult artificially ventilated, decerebrate rabbits...

Idiopathic pulmonary fibrosis (IPF) is a major cause of respiratory failure in critically ill patients and common outcome of various lung interstitial diseases. Its mortality remains high, and no effective pharmacotherapy, in addition to artificial ventilation and transplantation, exists. As such, the administration of mesenchymal stem or stromal cells (MSCs) is currently investigated as a new therapeutic method for pulmonary fibrosis. Clinical trials on MSC-based therapy as a potential treatment for lung injury and fibrosis are also performed...

Extracorporeal membrane oxygenation (ECMO) is a life support technique used in patients with respiratory and/or cardiac failure. The ECMO circuit consists of vascular cannulae, a pump and an artificial lung. Infections are among the most common complications associated with ECMO and have a significant impact on the mortality rate. Here we present a narrative literature review regarding the epidemiology, risk factors, pathogenesis and prevention of infectious complications during ECMO support. The prevalence of hospital-acquired infections during ECMO is 10-12% and their occurrence is likely to be more frequent compared with other critically ill patients...

OBJECTIVES: The Belgian Public Health Organization is concerned with rates of hospital-acquired infections like ventilator-associated pneumonia (VAP). Implementing best practice guidelines for these nosocomial infections has variable success in the literature. This retrospective study was undertaken to see whether implementation of the evidence-based practices as a bundle was feasible, would influence compliance, and could reduce the rates of VAP. STUDY DESIGN: We utilized easily collectable data about regular care to rapidly assess whether interventions already in place were effectively successfully applied...

BACKGROUND: Assessment of the default mode network (DMN) using resting-state functional magnetic resonance imaging (fMRI) may improve assessment of the level of consciousness in chronic brain injury, and therefore, fMRI may also have prognostic value in acute brain injury. However, fMRI is much more challenging in critically ill patients because of cardiovascular vulnerability, intravenous sedation, and artificial ventilation. METHODS: Using resting-state fMRI, we investigated the DMN in a convenience sample of patients with acute brain injury admitted to the intensive care unit...

Impaired breathing is a devastating result of high cervical spinal cord injuries (SCI) due to partial or full denervation of phrenic motoneurons, which innervate the diaphragm - a primary muscle of respiration. Consequently, people with cervical level injuries often become dependent on assisted ventilation and are susceptible to secondary complications. However, there is mounting evidence for limited spontaneous recovery of respiratory function following injury, demonstrating the neuroplastic potential of respiratory networks...
