Filter by:Patients who met the inclusion criteria were included and signed an informed consent form, which complied with the requirements of the ethics committee of our unit. All subjects were inpatients. Subjects were randomized into two groups. patients in group A were first treated with HFNC on top of conventional treatment, and after 24 hours, patients were treated with non-invasive ventilator-assisted ventilation BiPAP mode until discharge. patients in group B were treated with a non-invasive ventilator on top of conventional treatment, and after 24 hours of treatment, patients were treated with HFNC until discharge. Patient information was collected during treatment.
Finger pulse oximetry SpO2 is widely used to estimate arterial oxygen saturation SaO2. Current Spo2 targets do not take into consideration the many variables that affect that correlation in particular skin pigmentation. This study aims to evaluate different FDA approved pulse oximeters (Nonin co-pilot, massimo Radical 7, Philips-standard of care monitor, innovo premium iP900BP, nellcor PM1000N, Nano100) with SaO2 reference values obtained by an arterial blood gas in subjects with different skin pigments measured by a skin color scale as well as self-identification of race.
The aim of the study is to asses safety and indications and contraindications for performing bronchofiberocopy (FB) with respiratory support methods, i.e. non-invasive ventilation (NIV) and high flow nasal oxygen therapy (HFNO). Additionally, researchers want to determine how using these methods could avoid the risk of most common complications such as: hypoxemia-related events, decompensation of chronic respiratory failure, worsening of gas exchange, hemodynamic instability.
More than 2 million patients worldwide receive heart surgery every year, majority of these surgical patients will undergo cardiopulmonary bypass. However, the incidence of postoperative acute lung injury due to cardiopulmonary bypass is still as high as 20% to 35%. According to clinical experience, the earlier lung damage is detected, the more successful the treatment will be. On the basis of traditional detection, the investigators found a new indicator, serum soluble vascular endothelial-cadherin, which are easy to obtain and have certain specificity. Importantly, they can predict postoperative acute lung injury within 1 hour after cardiac surgery. It is meaningful that this indicator can provide clinicians with early decision-making advice and immediate treatment for patients who may be at risk.
This investigator-initiated, prospective, randomized, blinded, multi-center, controlled trial will investigate the effect of a restrictive vs. liberal oxygenation-strategy in patients hospitalized with acute heart failure with pulmonary congestion. Patients will be randomized 1:1 in the emergency department to either liberal or restrictive oxygenation after providing informed written consent. 1. Liberal oxygenation group = SpO2 target of 96%. 2. Restrictive oxygenation group = SpO2 target of 90%. The allocation will be concealed through the use of an oxygen-delivery robot, termed O2MATIC. The study will include 122 patients.
To determine whether a strategy of adding venovenous ECMO to mechanical ventilation, as compared to mechanical ventilation alone, increases the number of intensive care free days at day 60, in patients with moderate to severe acute hypoxic respiratory failure.
Twelwe patients with COPD and long term oxygen treatment (LTOT) will be included in the study. An automated home oxygen titrations (HOT) device will be attached to the patient´s home oxygen equipment. For 2x4 consequent days, the patients will be monitored and saturations, oxygen flow and physical activity level will be registered. In randomized order, the patients will use their usual fixed oxygen dose or automated oxygen titration during the first four days and then crossover. The monitoring consists of a wrist pulse oximeter (register pulse and saturation which is send to the HOT device) and a physical activity sensor attached to the patient's knee. At study start and after both of the four days the patients´dyspnea and QoL will be assessed. After the study period the patients will in an explorative design based on qualitative methodology be interviewed in order to explore the patients experiences with automated oxygen titration during daily activity and on dyspnea.
This is a prospective observational study designed to quantify and understand errors in pulse oximetry in hospitalized patients in relation to their skin pigmentation. It is driven by three recent retrospective studies showing missed diagnosis of hypoxemia in patients across a spectrum of skin pigmentation, defined as blood SaO2 <90% when their pulse oximeter reads 92% or greater.
This study within a trial (SWAT) will be a sub-study of the UK-ROX trial (ISRCTN13384956), which is currently running in intensive care units across the UK. UK-ROX is large-scale randomised controlled trial evaluating conservative oxygen therapy (a target SpO2 of 88-92%) versus usual oxygen therapy in mechanically ventilated adult patients admitted to ICUs in the UK. The purpose of this observational sub-study is to compare pulse oximeter-derived peripheral oxygen saturation (SpO2) values to co-oximeter-derived arterial oxygen saturation (SaO2) measurements from arterial blood gas (ABG) samples, for a range of fingertip pulse oximeters in an ethnically diverse group of adult patients admitted to UK intensive care units (ICUs). Approximately 900 patients will be recruited over 12 month period from 24 sites to provide an anticipated 10,800 paired SpO2 and SaO2 measurements. Patient skin tone will be objectively measured using a handheld spectrophotometer. Data from the sub-study will be used to determine the accuracy of the tested pulse oximeters across a range of skin tones and arterial oxygenation levels.
The proposed research study will be a prospective observational study designed to validate the Canadian Triage Assessment Scale (CTAS) in regard to work of breathing in patients in the emergency department. The investigators will assess inter-rater agreement between nurses & emergency physicians for assessment of work of breathing.
