PURPOSE: Although capnography is considered the gold standard for monitoring of ventilation, it may not work accurately in some situations. We compared the performance of two non-invasive continuous respiratory rate (RR) monitors that are alternatives for the detection of respiratory depression. METHODS: Fifty healthy volunteers ≥20 years old were enrolled in this study. After monitoring of the volunteers was started by the Masimo Radical-7(®) and Nellcor™ PM1000N, they breathed at the rate of 12 breaths/min for 3 min and then stopped breathing...

BACKGROUND: Noninvasive ventilation (NIV) significantly changed the management of respiratory distress syndrome (RDS) in preterm infants. Further perspectives for neonatologists regard the assessment of different NIV strategies in terms of availability, effectiveness and failure. OBJECTIVE: The aim of the present study is to evaluate the effectiveness of three different NIV strategies: nasal continuous pressure (N-CPAP), nasal synchronized intermittent positive pressure ventilation (N-SIPPV) and nasal bilevel CPAP (BiPAP), as first intention treatment for RDS in very low birth-weight infants (VLBW)...

Electrical Impedance Tomography (EIT) uses electrical stimulation and measurement at the body surface to image the electrical properties of internal tissues. It has the advantage of non-invasiveness and high temporal resolution but suffers from poor spatial resolution and sensitivity to electrode movement and contact quality. EIT can be useful to applications where there are conductive contrasts between tissues, fluids or gasses, such as imaging of cancerous or ischemic tissue or functional monitoring of breathing, blood flow, gastric motility and neural activity...

BACKGROUND: Bariatric surgery has proven a successful approach in the treatment of morbid obesity and its concomitant diseases such as diabetes mellitus and arterial hypertension. Aiming for optimal management of this challenging patient cohort, tailored concepts directly guided by individual patient physiology may outperform standardized care. Implying esophageal pressure measurement and electrical impedance tomography-increasingly applied monitoring approaches to individually adjust mechanical ventilation in challenging circumstances like acute respiratory distress syndrome (ARDS) and intraabdominal hypertension-we compared our institutions standard ventilator regimen with an individually adjusted positive end expiratory pressure (PEEP) level aiming for a positive transpulmonary pressure (P L) throughout the respiratory cycle...

Adaptive servo-ventilation (ASV) is a recently-developed non-invasive therapy that improves the clinical course of heart failure (HF) patients. However, the precise hemodynamic response and predictors of ASV therapy remain uncertain. Overall, 69 patients with New York Heart Association HF class II-IV underwent 10-minute ASV testing along with hemodynamic studies. Among them, 21 (30%) achieved an acute response, which was defined as an increase in the cardiac index (CI) during ASV. ΔLeft ventricular end-diastolic pressure (LVEDP) did not correlate with ΔCI, whereas Δtransmural LVEDP, which was calculated by subtracting right ventricular end-diastolic pressure (RVEDP) from LVEDP, and ΔCI were positively correlated, similar to the ascending limb of Frank-Starling's law (P = 0...

BACKGROUND: Despite wide use of noninvasive ventilation (NIV) in several clinical settings, the beneficial effects of NIV in patients with hypoxemic acute respiratory failure (ARF) due to influenza infection remain controversial. The aim of this study was to identify the profile of patients with risk factors for NIV failure using chi-square automatic interaction detection (CHAID) analysis and to determine whether NIV failure is associated with ICU mortality. METHODS: This work was a secondary analysis from prospective and observational multi-center analysis in critically ill subjects admitted to the ICU with ARF due to influenza infection requiring mechanical ventilation...

Capnography (ETCO2 ) is routinely used as a non-invasive estimate of arterial carbon dioxide (PaCO2 ) levels in order to modify ventilatory settings, whereby it is assumed that there is a positive gap between PaCO2 and ETCO2 of approximately 0.5 kPa. However, negative values (ETCO2 > PaCO2 ) can be observed. We retrospectively analysed arterial to end-tidal carbon dioxide differences in 799 children undergoing general anaesthesia with mechanical ventilation of the lungs in order to elucidate predictors for a negative gap...

Although non-invasive ventilation (NIV) has been used since the 1960's in the polio epidemic, the development of modern bilevel PAP devices did not become a reality until the 1990's. Over the last 25 years bilevel PAP technology options have exponentially increased. The number of patients receiving this treatment both in the acute setting as well as at home is steadily growing. However, a knowledge gap exists in the way these device settings are adjusted to achieve synchrony and match patient's unique respiratory failure physiology...

BACKGROUND: Traumatic brain injury (TBI) has become the most common cause of death and disability in persons between 15 and 30 years of age, and about 10-15% of patients affected by TBI will end up in a coma. Coma caused by TBI presents a significant challenge to neuroscientists. Right median nerve electrical stimulation has been reported as a simple, inexpensive, non-invasive technique to speed recovery and improve outcomes for traumatic comatose patients. METHODS/DESIGN: This multicentre, prospective, randomised (1:1) controlled trial aims to demonstrate the efficacy and safety of electrical right median nerve stimulation (RMNS) in both accelerating emergence from coma and promoting long-term outcomes...

In patients with muscular dystrophies both muscle length tension relationship changes and muscle elasticity and plasticity are decreased, resulting in impaired inspiratory muscle function and decreased vital capacity. Furthermore, the loss of deep breathing further increases the risk of alveolar collapse, hypoventilation and atelectasias. In this case report, a stable improvement of vital capacity after treatment with mounthpiece ventilation (MPV), was observed, suggesting that not invasive ventilation (NIV) might help to maintai lung and chest wall compliance, prevent hypoventilation and atelectasias which in turn may slow down the development of the restrictive respiratory pattern...

Poor nutritional status in HCT patients is a negative prognostic factor. There are no pediatric studies evaluating albumin levels prior to HCT and need for critical care interventions. We hypothesized that pediatric patients with low albumin levels, routinely measured 30 days (±10 days) prior to allogeneic HCT, have a higher risk of critical care interventions in the post-transplant period. We performed a 5-year retrospective study of pediatric patients who underwent allogeneic HCT for any indication. Patients were categorized based on albumin level...
