Filter by:Oxygen supplementation through high flow nasal cannula (HFNC) may reduce the incidence of desaturation and hypoxemia during deep sedation at radiofrequency catheter ablation (RFCA procedures).This study is designed to test the hypothesis that the incidence of hypoxemia and desaturation in patients with atrial fibrillation undergoing RFCA under deep sedation, is less when using HFNC as compared to use of standard low flow nasal cannula (LFNC).
To assess the benefits and drawbacks of high versus low oxygen therapy on mortality and myocardial function in mechanically ventilated patients
The use of mobile technology has become part of the reality capable of changing the health services' paradigm. As a proof of that, nowadays, technology is seemed as a key tool in processes such as: data collection, epidemiological surveillance, health promotion, and disease prevention. Therefore, technological tools should be taken as an advantage to optimize the control or monitoring of patients with chronic diseases including those who require the use of home oxygen therapy. Objective: Determine the efficiency of a mobile application for clinical monitoring of patients who require home oxygen therapy. Methods A randomized-controlled clinical trial including individuals whose age is 18 years or older who have been diagnosed with Chronic Obstructive Pulmonary Disease (COPD) under treatment with home oxygen therapy. The sample will be divided in two groups: the intervention group will be made up of those who are followed up with the mobile app, and the control group will be made up of the patients who are followed up conventionally (regular visit of the respiratory caregiver). To measure the effect of the intervention, some outcomes variables will be taken as the recognition of self-management of dyspnea, number of exacerbations associated with oxygen therapy, and the frequency of underutilization of oxygen supplies.
Most premature babies require oxygen therapy. There is uncertainty about what oxygen levels are the best. The oxygen levels in the blood are measured using a monitor called a saturation monitor and the oxygen the baby breathes is adjusted to keep the level in a target range. Although there is evidence that lower oxygen levels maybe harmful, it is not known how high they need to be for maximum benefit. Very high levels are also harmful. Saturation monitors are not very good for checking for high oxygen levels. For this a different kind of monitor, called a transcutaneous monitor, is better. Keeping oxygen levels stable is usually done by nurses adjusting the oxygen levels by hand (manual control). There is also equipment available that can do this automatically (servo control). It is not known which is best. Studies of automated control have shown that infants spend more time within their intended target oxygen saturation range. These have not included measurements of transcutaneous oxygen. There are no previous studies directly comparing automated respiratory devices. The investigators aim to show the transcutaneous oxygen levels as well as the oxygen saturation levels when babies have their oxygen adjusted using two automated (servo) control devices delivering nasal high flow. For a period of 12 hours each baby will have their oxygen adjusted automatically using each devices for 6 hours respectively. The investigators will compare the range of oxygen levels that are seen between the two respiratory devices.
The SARS-Cov2 viral pandemic is responsible for a new infectious disease called COVID-19 (CoronaVIrus Disease), is a major health problem. Respiratory complications occur in 15 to 40%, the most serious is acute respiratory distress syndrome (ARDS). The management of COVID-19 is essentially symptomatic with respiratory oxygen supplementation in mild forms to invasive mechanical ventilation in the most severe forms. Prone position (PP) reduced mortality in patients with ARDS in intensive care. Ding et al showed that PP and high flow oxygenation reduced the intubation in patients with moderate to severe ARDS. The investigators hypothesize that the use of PP in spontaneously ventilation patients under oxygen standard could decrease incidence of intubation or non-invasive ventilation or death compared to conventional positioning management in medical departments.

Acute left heart failure (ALHF) is a sudden attack or deterioration of abnormal left heart function, which may impair myocardial contractility and increase cardiac loading, further result in decreased cardiac output, abrupt elevation of pulmonary and systemic circulation pressure, consequently trigger in acute pulmonary congestion, acute pulmonary edema and cardiac shock . Hypoxia and severe dyspnea may pose fatal threats for the patients suffered from ALHF should be alleviated as soon as possible, and thus oxygen therapy and ventilation support are regarded as important therapeutic measures for these patients. According to 2017 Chinese College of Emergency Physicians(CCEP) acute heart failure clinical guideline, invasive ventilation should be recommended to those patients whose symptoms still get worsening despite timely treatments. Intubation may increase the risks of infection and multiple organ failure, so timely extubation contributes to reduce the duration of mechanical ventilation and the rate of complications. But if extubation failure occurs, the patient often requires re-intubation that may induce the outset of complications, extend the length of stay and increase mortality. Heart failure proves to be high risk factor for extubation failure on the basis of previous studies. It is recommended to apply sequential non-invasive ventilation (NIV) if the patient receiving invasive ventilation for more than 24 hours and having high risk for extubation failure on the basis of 2017 American Thoracic Society(ATS) clinical guideline. It is worthy to note that NIV has many shortcomings, for example, it may induce dry oropharyngeal cavity, skin injury caused by mask oppression, gaseous distention, vomiting, respiratory aspiration, air leak, drying sputum, difficulty in coughing up phlegm and claustrophobia. As an emerging technology, high flow nasal oxygen (HFNO) has many advantages in airway humidification, tolerance and compliance which also can effectively improve pulmonary oxygenation function of patients with respiratory failure. Which therapeutic measure should be recommended for the patients with ALHF after extubation, NIV or HFNO? It is still unclear according to the latest management guidelines. So one perspective study will be launch to compare the difference between HFNO-group patients with NIV-group patients in re-intubation rate within 48 hours, oxygenation index, length of ICU stay, total hospital stay, mortality and compliance for evidence-based medicine.
The objective of this study is to determine the multifactorial relationship between the effective fraction of inspired oxygen (Effective-FiO2) and the FiO2 in the gas delivered by the nasal cannula (NC-FiO2), NC flow rate, spontaneous minute ventilation and other patient characteristics in premature infants who receive supplemental oxygen via nasal cannula (NC).
High-flow nasal cannula (HFNC) that uses heated and humidified oxygen was recently introduced for bedside care. It has been shown to be associated with reduced risks of tracheal intubation rates and mortality in adult hypoxic patients. The mechanisms of the effects of HFNC are thought to be related to the favorable effects of the heated and humidified gas, the high-flow rate used to minimize the entrainment of room air, and an increase in the ventilation efficiency, including the elimination of nasopharyngeal dead space, positive end-expiratory pressure (PEEP) effects, and improvements in paradoxical abdominal movement. Regarding the effects on lung volume, global ventilation in the lungs increases during HFNC, which is thought to attribute to PEEP effects. However, how regional ventilation is affected during HFNC in comparison with conventional NC remains unknown. Because PEEP in mechanically ventilated patients improves the regional homogeneity of ventilation, investigators postulated that HFNC via PEEP effects would result in more homogeneous regional distributions in the ventilation changes. Investigators therefore assessed global and regional ventilation in patients with hypoxia receiving care via HFNC using electric impedance tomography and compared these results with conventional nasal cannula.
The purpose of this study is to compare pharyngeal FiO2 in day time with nasal normobaric O2 with inhaled FiO2 in the night time with home care ventilator NIV at the same O2 flow.
