High Flow Nasal Cannula Versus Non-Invasive (NIV)in Both Hypoxemic and Hypercapnic Respiratory Failure....
Acute Hypoxemic Respiratory FailureAcute Hypercapnic Respiratory Failurehigh flow nasal cannula (HFNC) oxygen therapy utilizes an air oxygen blend allowing from 21 % to 1 00% FiO2 delivery and generates up to 60 L/min flow rates The gas is heated and humidified through an active heated humidifier and delivered via a single limb heated inspiratory circuit (to avoid heat loss and condensation) to the patient through a large diameter nasal cannula Theoretically, HFNC offers significant advantages in oxygenation and ventilation over COT. Constant high flow oxygen delivery provides steady FiO2 and decreases oxygen dilution. It also washes out physiologic dead space and generates positive end expiration pressure (PEEP) that augments ventilation The heated humidification facilitates secretion clearance, decreases bronchospasm, and maintains mucosal integrity. This study aims to evaluate the effectiveness of HFNC compared to NIMV in management of Acute hypoxemic and acute hypercapneic respiratory failure
Explore Potential Plasma and BALF Immunometabolic and Lipidomic Biomarkers for Identifying ARDS...
Acute Respiratory Distress SyndromeAcute Respiratory FailureAcute respiratory distress syndrome (ARDS) is a life-threatening condition that causes high mortality (41% to 58%). Previous studies have reported that biomarkers can facilitate phenotypic diagnosis of ARDS, enabling precision treatment of ARDS. Although there were many studies that found some potential therapeutic targets for ARDS, no pharmacotherapies have been validated to treat ARDS. The development of biomarkers to predict the prognosis and monitor the response to treatment would be of interest for selecting patients for specific therapeutic trials. Many recent studies have shown that immune metabolic changes are involved in the pathogenesis of ARDS and may become a new therapeutic target for them. We aimed to identify a panel of immunometabolic and lipidomic biomarkers derived from blood and bronchoalveolar lavage fluid (BALF) which may help differentiate the ARDS endotypes.
Evaluation on the Effect of Acupuncture and Neuromuscular Electrical Stimulation on Mechanical Ventilation...
Respiratory Insufficiency Requiring Mechanical VentilationAcupuncture is a treatment intervention used globally for a wide variety of disorders. Its efficacy has been established over the course of 3000 years, originating in Asia and diversifying worldwide.The scientific basis for acupuncture remains unclear. Nonetheless, acupuncture releases neurochemical substrates, such as endorphins, serotonin, and norepinephrine.Acupuncture is considered to be a safe treatment when applied by a certified acupuncturist.Acupuncture has already been deployed in the treatment of sepsis or muscle weakness.Studies have revealed that acupuncture significantly improved grip strength and respiratory muscle strength in chronic obstructive pulmonary disease participates.Neuromuscular electrical stimulation (NMES) is an alternative to mobilize and exercise because it does not require active patient participation and can be used on bedridden patients.The investigators designed a study to compare the effects of acupuncture, electroacupuncture, and neuromuscular electrical stimulation on mechanical ventilation patients with weaning difficulties
The Impact of Age-dependent Haptoglobin Deficiency on Plasma Free Hemoglobin Levels During Extracorporeal...
Respiratory FailureNewborns and children with life-threatening heart and lung failure may require support with ECMO (extracorporeal membrane oxygenation). With ECMO, oxygen and carbon dioxide are exchanged and circulated throughout the body even if the heart is unable to do so. Unfortunately, ECMO can cause breakdown of the red blood cells (known as hemolysis). For unclear reasons, newborns are at particularly high risk of hemolysis while being supported by ECMO. The amount of hemolysis is measured with concentrations of a breakdown product from red blood cells known as free hemoglobin. One possible reason for high free hemoglobin levels in newborns on ECMO could be related to another blood protein called haptoglobin. Haptoglobin is known to help in clearing free hemoglobin through the kidneys into the urine. However, haptoglobin levels in newborns can be very low and increases slowly during the first few months of life. Free hemoglobin may be inappropriately high in newborns supported by ECMO because of low levels of haptoglobin. The purpose of this study is to characterize haptoglobin, free hemoglobin, and hemolysis in newborns and children supported by ECMO and compare those values to age-matched newborns and children not on ECMO.
Clinical Relevance of Nicardipine Induced Hypoxemia in the Intensive Care Unit
Hypoxemic Respiratory FailureSide Effect1 moreIn the context of postoperative hypertension in the intensive care units, or after resusitation of hypertensive patients, intravenous antihypertensive drugs are often used. Among those drugs, Nicardipine is an effective drug, but with side effects such as inhibition of pulmonary vasoconstriction. Only preclinical studies have investigated the pathophysiology of this mechanism, and no clinical study have proven its clinical relevance. The aim of this study is to establish the incidence of Nicardipine induced hypoxemia and to compare it to another antihypertensive agent, Urapidil.
Effect of Different Sedation and Analgesia Strategies on Patients With Mechanical Ventilation
Respiratory InsufficiencyMost patients in ICU are treated with a combination of analgesics and sedatives in most cases. Due to the different mechanism of different sedative and analgesic drugs, different antagonistic or synergistic effects may occur when combined with drugs, resulting in different clinical effects, especially significant effects on ventilators for patients with assisted breathing. Therefore, this study hopes to compare the effects of different sedative and analgesic drug combinations on the duration of mechanical ventilation for patients with ventilators, so as to guide the clinical adoption of a more reasonable sedative and analgesic scheme.

Handling Oxygenation Targets in COVID-19
Hypoxemic Respiratory FailureOxygen ToxicityPatients with COVID-19 and hypoxaemic respiratory failure and admitted to the intensive care unit (ICU) are treated with supplementary oxygen as a standard. However, quality of quantity evidence regarding this practise is low. The aim of the HOT-COVID trial is to evaluate the benefits and harms of two targets of partial pressure of oxygen in arterial blood (PaO2) in guiding the oxygen therapy in acutely ill adult COVID-19 patients with hypoxaemic respiratory failure at ICU admission.
Epidemiologic, Clinical and Molecular Characteristics of Patients With Acute Respiratory Failure...
Covid19The main purpose of this study is to identify possible predictor factor of mortality in patients affected by COVID-19 with respiratory failure needing oxygen therapy or ventilatory support. In addiction the study aims to identify factors related to: predisposition to SARS-CoV2 viral infection, different symptoms, response to therapy, predisposition to complications related to the disease. To this end, the haemodynamic parameters and all imaging reports will be evaluated and clinical and laboratory tests as well as cellular and molecular analyzes will be performed in the analyzed patients. In addition, investigations will be carried out on the profile of the alveolar or nasal microbiota and, if possible, of the metabolic products, and estimates on antibody titers.
PEEP in Patients With Acute Respiratory Failure
Acute Respiratory Failure With HypoxiaPositive end-expiratory pressure (PEEP) has become an essential component of the care of critically ill patients who require ventilatory support. In 1975, several investigators published the effects of PEEP in 15 mechanically ventilated patients with acute respiratory failure (ARF) supported by mechanical ventilation. FiO2 ranged between 21% to 75% and the tidal volume between 13 to 15 mL/kg. PEEP was increased in 3 cmH2O steps until cardiac output fell. The aim was to identify the "optimum" PEEP level. "Best" PEEP was associated simultaneously with the best static compliance of the respiratory system, the greatest oxygen transport, and the lowest dead space fraction. That study established the basis for the use of PEEP in patients with ARF worldwide. Although currently patients with ARF are ventilated with much lower tidal volumes, that study has never been validated. It is unknow whether their findings are currently valid, generalizable, and reproducible.
