Providing Optimal PEEP During Mechanical Ventilation for Obese Patients Using Esophageal Balloon

This is a research study to determine if identifying an optimal level of positive end-expiratory pressure (PEEP) targeted specifically to individualized patient characteristics will shorten the time on the ventilator. Participants will have catheter placed through the nose into the esophagus to measure the pressure inside the chest. This catheter will remain until the patient is freed from the ventilator. Participants will be randomized to usual care or to have the level of PEEP determined by the esophageal balloon pressure readings. The total time spent on the ventilator will be recorded.

OxyGap : Comparaison Between Different Pulse Oximeter and With the Arterial Blood Gase

The oximeter is used to monitor intensive care patients undergoing oxygen therapy. It indicates pulsed oxygen saturation (SpO2), a reflection of arterial oxygen saturation (SaO2) which enables detection of hypoxemia and hyperoxia, both deleterious state. Current SpO2 recommendations aim to reduce both risk of hypoxemia and hyperoxia. SpO2 is considered the 5th vital sign. Current recommendations for SpO2 targets do not consider the variability of oximeters used in clinical practice. This variability and lack of specification represent an obstacle to an optimal practice of oxygen therapy. Thus, this study aims to compare the SpO2 values of different oximeters (Nonin, Masimo, Philips, Nellcor) used in clinical practice with the SaO2 reference value obtained by an arterial gas in order to specify the precision and the systematic biases of the oximeters studied. This data will also make it possible to refine the recommendations concerning optimal oxygenation

Repeated Measures Trial of Temporary Automated Manual Ventilation Versus Noninvasive Oxygenation or Conventional Vent

The COVID-19 pandemic has led to a potential shortage of life-saving mechanical ventilators. The purpose of this study is to determine whether a novel simpler to device, the automated bag-valve-mask (BVM) compressor, can be used to provide assisted ventilation temporarily to patients in need. This includes patients with COVID-19 lung infection and respiratory failure. If successful, this would increase the pool of total available ventilator hours to alleviate any shortage.

CYCLE: A Randomized Clinical Trial of Early In-bed Cycling for Mechanically Ventilated Patients

Patients who survive critical illness usually experience long-lasting physical and psychological impairments, which are often debilitating. Rehabilitation interventions started in the ICU may reduce this morbidity. In-bed cycling, which uses a special bicycle that attaches to the hospital bed, allows critically ill patients who are mechanically ventilated (MV) to gently exercise their legs while in the ICU. The main goal of this study is to determine whether critically ill MV adults recover faster if they receive early in-bed cycling than if they do not. Another objective is to determine whether in-bed cycling is a cost-effective intervention. 360 patients admitted to the ICU and receiving MV will be enrolled in the study. Following informed consent, patients will be randomized to either (1) early in-bed cycling and routine physiotherapy or (2) routine physiotherapy alone. Patients' strength and physical function will be measured throughout the study. If early in-bed cycling during critical illness improves short-term physical and functional outcomes, it could accelerate recovery and reduce long-term disability in ICU survivors.

Stress Related Disorders in Family Members of COVID-19 Patients Admitted to the ICU

Coronavirus disease 2019 (COVID-19) is a novel infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This syndrome has been associated with high mortality, estimated to be about 1.7% of all infected in the US, though in those who develop acute respiratory distress syndrome (ARDS) in the context of the infection, mortality rates appear to be much higher, perhaps up to 70%. To avoid transmission of the virus, patient isolation has become the standard of care, with many hospitals eliminating visitors of any type, and particularly eliminating visitation to patients infected with COVID-19. These necessary, but restrictive, measures add stress to the ICU and particularly to the family members who are not only left with fear, but also many unanswered questions. In contrast to the Society of Critical Care Guidelines (SCCM) which recommend family engagement in the ICU and recent data from this study team which suggests engaging families in end-of-life situations reduces symptoms of Post-Traumatic Stress Disorder (PTSD) in family members, family members are now unable to say good-bye and unable to provide support to their loved-one throughout the process of the patients' ICU stay. The study hypothesizes is that these restrictive visiting regulations will increase rates of Post-intensive care syndrome- family (PICS-F) which includes symptoms of PTSD, depression, and anxiety and aim to evaluate for factors that either exacerbate these symptoms or protect from them.

Analysis of Endotoxin Activity in Patients With ECMO

Extra-corporeal membrane oxygenation (ECMO) can temporarily help patients gain time to wait for cardiopulmonary recovery or further treatment in patients with cardiopulmonary failure. Whether the blood flow provided by the ECMO can maintain the perfusion of various organs is an important factor affecting survival. Some ECMO patients died after the complication of sepsis. Our previous pilot analysis has recognized several ECMO patients with complicated sepsis has high endotoxin activity level. Endotoxemia can also occur in heart surgery and after cardiopulmonary bypass, trauma, organ transplantation, and out-of-hospital cardiac arrest patients. These trials used endotoxin activity analysis (EAA, EAATM, Spectral Diagnostics Inc., Canada) to analyze endotoxin activity. In addition, studies have indicated that the combination of procalcitonin (PCT) concentration and EAA activity can improve the accuracy of predicting sepsis. The primary aim of this study is to detect endotoxin activity in patients with ECMO support and compare whether the prognosis was associated with different level of EAA activity. The secondary aims are to analyze the risk factors leading to high EAA activity and investigate the diagnostic value of septic shock combining PCT examination. We suggest that the results of this study may help the ECMO medical team identify patients at high risk for septic shock and conduct adequate managements to improve patient survival and quality of life after survival.

The Impact of Age-dependent Haptoglobin Deficiency on Plasma Free Hemoglobin Levels During Extracorporeal Membrane Oxygenation Support

Newborns 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.

MICU Recovery Clinic

Summary: Emerging data demonstrate long-term morbidity and mortality in those who survive critical illness. However, there is no data regarding long-term follow-up for ICU survivors. The investigators have begun the implementation of an ICU recovery clinic. Rationale: ICU survivors are at high risk for functional, cognitive and psychiatric impairments. However, methods to mitigate these impairments and improve recovery are lacking. Special follow-up clinics for survivors of critical illness have been proposed and implemented to some degree, but are uncommon.
