Filter by:Background High-flow nasal cannula (NHF) are a promising tool for administering oxygen to critically ill patients with high respiratory demand. Prone positioning (PP) is a simple and cost-effective strategy that since 1980s has been used in mechanically ventilated patients with acute respiratory failure to treat oxygenation impairment. A large randomized study detected a relevant survival benefit by prone positioning in patients with moderate to severe acute respiratory distress syndrome (ARDS) undergoing invasive mechanical ventilation and managed with the ARDS network PEEP-FiO2 table strategy. Theoretically, PP may benefit spontaneous breathing patients too, but data concerning its application in such context are limited to small case series and a retrospective study. The investigators designed a pilot feasibility study to assess the safety and efficacy of prone positioning in acute hypoxemic respiratory failure patients noninvasively treated with NHF. Methods Patients: 15 adult hypoxemic (PaO2/FiO2<200 mmHg with respiratory rate greater than 25 breaths per minute) non-hypercapnic patients with acute respiratory failure. PaO2/FiO2 will be assessed while the patients is receiving 50 L/min of 50% oxygen via a standard face mask for a 15-minute monitoring period at study entry. Protocol Eligible patients will undergo NHF for 1 hour in the supine semi-recumbent position (baseline, BL). Afterwards, each enrolled patient will be placed in the prone position for 2 hours. After a 2-hour PP period, the patient will be rotated and will undergo 1 hour of NHF in the semi recumbent supine position (Supine step). Measurements Patient's demographics will be collected at study entry. At the end of the monitoring period, and then on a hourly basis the following data will be collected: - Respiratory rate, SpO2, pH, PaCO2, PaO2, SaO2, PaO2/FiO2; - Heart Rate, arterial blood pressure; - Dyspnea, as defined by the VAS dyspnoea scale; - Discomfort, as defined by a visual analogic scale (VAS) adapted to rate the procedural pain of ICU patients; - End expiratory lung impedance (EELI), tidal volume distribution, global and regional lung dynamic strain (Change in lung impedence due to tidal volume/ELLI). - Work of breathing, assessed by pressure-time product (PTP) of the esophageal pressure and inspiratory swings in this signal. - Occurrence of pendelluft phenomenon The number of adverse events will be also recorded for each study step.
Sufficient oxygenation is critical for completely buried avalanche victims to avoid life-threatening consequences during hypoxic exposure. Snow contains a remarkable capacity to maintain air availability; it was suspected that the snow physical properties affect the development of hypoxia and hypercapnia. The aim of this study was to evaluate the influence of different snow physical properties on the development of hypoxia and hypercapnia in subjects breathing into an artificial air pocket in snow. Twelve male healthy subjects breathed through an airtight face-mask and 40cm tube into an artificial air pocket of 4L. Every subject performed three tests on different days with varying snow characteristics. Symptoms, gas and cardiovascular parameters were monitored up to 30min. Tests were interrupted at SpO2 <75% (primary endpoint); or due to subjective symptoms like dyspnea, dizziness, and headache (i.e. related to hypercapnia). Snow density was assessed via standard methods and micro-computed tomography (CT) analysis, and permeability and penetration with the snow micro-penetrometer (SMP).

The primary purpose of this study is to show whether at home usage of the AIRVO warm humidifier can potentially reduce the number of exacerbations in patients with significant respiratory insufficiency. Eligible participants of the study must have a diagnosis of chronic obstructive pulmonary disease (COPD) stage II-IV..
To understand if a progressive increase in end-tidal carbon dioxide (CO2) levels are heralding respiratory difficulties before desaturation measured from capnography in obstructive sleep apnea patients, with the use of nasal prongs, transcutaneous monitors, Capnostream, and Massimo technologies.
Noninvasive ventilation (NIV) is an alternative form of ventilatory support in critical care encompassing different modes of ventilation such as continuous positive airway pressure (CPAP), bilevel positive airway pressure (BiPAP) and high flow nasal cannula ventilation. Although numerous studies on adults exit in literature, the aspects of this ventilatory support is limited in pediatric age groups. Early recognition of respiratory failure and initiation of NIV in a pediatric patient would positively affect prognosis by avoiding certain complications of endotracheal intubation and mechanical ventilation and adds certain advantages. Decreasing re-intubation rates for the ones who are extubated but necessitating further oxygen support is another advantage of NIV. Although numerous studies on adults exit in literature, the aspects of this ventilatory support is limited in pediatric age groups. Besides, success as well as failure and complication rates in pediatric age groups vary extensively. This multi-centered, prospective cohort study is planned to observe the epidemiologic perspectives of study group within underlying problems, success rates between different age groups, complication and re-intubation rates and finally its' effect on prognosis and long term survival in a year period. Hence we believe results of this study would allow us to improve our knowledge on using this technique, applying different modes and parameters appropriately and design criteria to guide clinician in deciding which group of patients would benefit from NIV techniques.
During general anesthesia, functional residual capacity (FRC) is reduced. If the FRC is lower than the minimum volume required to maintain the opening of the airways, there is a derecruitment of the lung parenchyma, leading to the phenomenon of expiratory flow limitation (EFL). The Driving Pressure (DP) is the difference between the plateau pressure (Pplateau) and the Positive End-Expiratory Pressure (PEEP), and estimates the lung strain. The incidence of EFL and the importance of DP are not known in adult cardiac surgery, so it's necessary a study to assess both. The primary end-point of the study is to evaluate the correlation of DP and EFL with PPCs in adult cardiac surgery. The secondary end-point of the study is to evaluate: the mechanical ventilation time, the length of ICU and hospital stay, the rehospitalization and mortality. It will be a prospective, observational, non-pharmacological study. It will enroll 200 patients undergoing elective adult cardiac surgery.
This study will compare the novel methods of NS and BS with the standard technique of nasophayngeal aspiration (NPA) and routine ETT suction. We shall assess the samples for diagnosis of RSV, viral load and immune responses in the airways of babies with RSV infection. We shall also assess the genetics of babies included in this study, to see if they may be vulnerable to RSV infection.
The m-CCRP randomized controlled trial will evaluate the efficacy of a collaborative critical care recovery program from acute respiratory failure (ARF) survivors in accomplishing the Institute of Healthcare Improvement's triple aims of better health, better care, at lower cost. Primary Aim: To assess the efficacy of m-CCRP in improving the QOL of ARF survivors compared to attention control at twelve months post hospital discharge. Secondary Aims: 1. To evaluate the efficacy of m-CCRP in improving cognitive, physical, and psychological function of ARF survivors at twelve months post hospital discharge when compared to attention control. 2. To evaluate the efficacy of m-CCRP in reducing health-care utilization, defined as time from enrollment to emergency department visits and/or hospital re-admission, by ARF survivors as compared to attention control at twelve months post hospital discharge.
