Active clinical trials for "Hypoxia"

THRIVE (Transnasal Humidified Rapid-Insufflation Ventilatory Exchange) refers to the use of high-flow nasal cannula to augment the ability to oxygenate and ventilate a patient under general anesthesia. The use of high-flow nasal cannula oxygen supplementation during anesthesia for surgical procedures has been a recent development in the adult population, with limited data analyzing the pediatric population. This study will determine whether high flow nasal cannula oxygen supplementation during surgical or endoscopic procedures can safely prevent desaturation events in children under anesthesia.

Patients were classified into two equal groups using the presence or absence of hypertension during pregnancy into: hypertensive group (BP>140/90) and normotensive group (BP≤140/90. The surgical time intervals are assessed and classified the patients accordingly into short and log time interval subgroups (induction of regional anesthesia to delivery (I-D), initial skin incision to delivery (S-D), and uterine incision to delivery (U-D)

Endoscopic procedures are commonly performed using sedation. As drug-induced respiratory depression is a major cause of sedation-related morbidity, pulse oximetry has been established as standart practice . However SpO2 does not completely reflect ventilation. Capnography is an additional monitoring parameter which demonstrates respiration activity breath by breath. Unfortunately, in the state of moderate or deep sedation during diagnostic or therapeutic procedures (e.g.ERCP or colonoscopies), regular breathing is often disturbed by moving, squeezing, coughing or changes between nose and mouth ventilation causing leakage and therefore artifacts or misinterpretation of data acquired with ETCO2. These problems often restrict the use of side-stream capnography in clinical practice, although the American Society of Anesthesiologists have suggested in their guidelines that extended monitoring with capnography 'should be considered'in deep sedation. The oxygen reserve index (ORI) is a new feature of multiple wavelength pulse oximetry that provides real-time visibility to oxygenation status in the moderate hyperoxic range (PaO2 of approximately 100-200 mm Hg). The ORI is an "index" with a unit-less scale between 0.00 and 1.00 that can be trended and has optional alarms to notify clinicians of changes in a patient's oxygen status. When utilized in conjunction with SpO2 monitoring the ORI may extend the visibility of a patient's oxygen status into ranges previously unmonitored in this fashion. The ORI may make pre-oxygenation visible, may provide early warning when oxygenation deteriorates, and may facilitate a more precise setting of the required FiO2 level. In this study we aimed to show effectivity of capnography and ORİ monitoring to avoid respiratory events and hypoxia in sedated endoscopic patients. In this study we targeted totally 300 sedated endoscopy patients. Patients will randomize to two groups. In Group I anaesthesiologis will be able to use all the monitoring, where as in Group II will be blinded for ORİ. We will apply pre-oxygenation to obtain long safe apnea time. Approximately 5 min pre-oxygenation (5L/min via nasal cannula) will be used to reach steady state in oxygen reserve. We defined hypoxemia ; SpO2<95% and severe hypoxemia SpO2≤90%, hypoventilation; rise10 mmHg in ETCO2 compare to baseline, ETCO2≤30 mmHg and flat capnography.

The objective of this study is to compare the effects of twice-a-day 15-minute sessions of inpatient physical therapy (PT) to the standard daily 30 minute sessions. The patient outcomes that will be evaluated will be length of stay, change in functional status, and disposition (home/acute rehab vs. subacute/LTAC/death) in patients admitted with COVID-19.

This study aimed to identify the effect of oxygen reserve index monitoring on the occurrence of oxygen desaturation (<90%) in pediatric patients undergoing airway surgery.

Clinical evaluation of the accuracy of SpO2 measurements with the ANNE Limb Sensor compared to blood gas analysis in healthy, adult subjects. Hypoxia is induced in patients to different and stable levels of SaO2 over the range of 70-100%.

The objective of the present study is to determine whether intermittent hypoxia protects against ischemia-reperfusion injury in young and older healthy individuals. The investigators hypothesize that intermittent hypoxia will attenuate the reduction in flow-mediated dilation following ischemia-reperfusion injury.

Complications are common during endotracheal intubation of critically ill adults. Manual ventilation between induction and intubation ("bag-valve-mask" ventilation) has been proposed as a means of preventing hypoxemia, the most common complication of intubation outside the operating room. Safety and efficacy data, however, are lacking. PreVent is a randomized trial comparing manual ventilation between induction and laryngoscopy to no manual ventilation between induction an laryngoscopy during endotracheal intubation of critically ill adults. The primary efficacy endpoint will be the lowest arterial oxygen saturation. The primary safety endpoints will be the lowest oxygen saturation, highest fraction of inspired oxygen, and highest positive end-expiratory pressure in the 24 hours after the procedure.

The aim of the COSGOD Phase III trial is to examine, if it is possible to increase survival without cerebral injury in preterm neonates <32 weeks of gestation by monitoring the cerebral tissue oxygen saturation in addition to routine monitoring of arterial oxygen saturation and heart rate and specified clinical treatment guidelines during immediate transition period after birth (the first 15 minutes).

The area of aesthesia-induced atelectasis is much larger in the obese compared with the non-obese, but there may also be more airway closure and impaired matching of ventilation and lung blood flow. When an anesthetized patient is turned to the prone position, dynamic compliance (Cdyn) decreases and peak airway pressure increases unless the abdomen hangs freely to prevent the abdominal viscera from compromising the diaphragm movement. Although the Wilson frame is designed to allow the abdomen to hang, it partially compresses the anterior abdominal wall and therefore does not allow the abdomen to hang completely, especially in obese patients. This in turn increases peak airway pressure and decreases Cdyn, oxygenation. This study aimed to investigate the effects of a prolonged I:E ratio (i.e., 1:1) compared with the conventional I:E ratio of 1:2 on respiratory mechanics and hemodynamics during spine surgery in the prone position in obese patients. We hypothesized that, compared with an I:E ratio of 1:2, a ratio of 1:1 improve oxygenation without hemodynamic instability .
