Active clinical trials for "Hypoxia"

This prospective, blinded observational clinical study was aimed to determine the effect of hyperhydration and muscle loss measured by Bioelectrical impedance vector analysis (BIVA) on mortality. The aim was to compare hydratation parameters measured by BIVA: OHY, Extracellular Water (ECW) / Total Body Wate (TBW) and quadrant, vector length, phase angle (PA) with cumulative fluid balance (CFB) recording (input-output) in their ability in predicting mortality as the abilities of the prognostic markers PA (BIVA), Acute Physiology and Chronic Health Evaluation II (APACHE II - score) and presepsin (serum Cluster of Differentiation (CD) 14-ST). The investigators also compared BIVA nutritional indicators (SMM, fat) with BMI and laboratory parameters (albumin, prealbumin and C-reactive protein (CRP) inflammation parameters) in the prediction of mortality. An important goal was to evaluate the usability of the BIVA method in critically ill patients on extracorporeal circulation, to compare the impedance data of the extracorporeal membrane oxygenation (ECMO) and non-ECMO groups.

Vital signs of postoperative patient are monitored intensively in post-anesthesia care unit or intensive care unit, but the frequency of surveillance decreases in typical surgical wards. The continuous pulse oximetry in surgical wards is known to be useful in detection and prevention of hypoxemia, reducing complications caused by postoperative respiratory depression. However, continuous monitoring is not conducted, due to shortage of equipment and personnel. Recently, wearable device for measuring pulse oxygen saturation, which is inexpensive, applicable to patients with mobility, and can be monitored continuously through wireless connection, has been supplied. In this study, the investigators evaluate the effect of continuous monitoring of oxygen saturation with wireless device(MASIMO Radius-7) on postoperative patients who are transferred to general wards, and evaluate the effect of early intervention in reducing the event of hypoxemia.

This study will compare the impact of the Double-Trunk Mask (DTM) with the Non-Rebreather Mask (NRM) on the blood gases of patients with severe hypoxemia.

Comparison the effect of two different mechanical ventilation modes on tissue oxygenization.

Investigate effects of PEEP on pulmonary regional ventilation and perfusion assessed by EIT

The objective of this study is to show that the measurement of auditory and vibro-tactile evoked potentials, or the recording of the EEG signal during a motor imaging task, can be used in routine clinical situations to explore the state of consciousness of subjects in Non-responsive Awakening (or Chronic Vegetative State) or in Minimal Consciousness (or relational state) after a severe brain injury. Assumptions : Correlation between patient response rates obtained with the brain-machine interface and their clinical consciousness score (Coma Recovery Scale Revised score) Differentiation of the parameters of the evoked potentials P300 between patients in a vegetative state and those in a state of minimal consciousness

Due to their effects on hypoxic pulmonary vasoconstriction (HPV), dihydropyridine calcium channel inhibitors (CCI) could lead to hypoxia in patients with a pulmonary shunt. To the present time only preclinical studies and case reports focused on this potential adverse drug reaction. We aimed to assess the reporting association between CCI and hypoxia using the World Health Organization pharmacovigilance database (VigiBase®).

The purpose of this study is to better understand how hypoxia (low oxygen) affects resting and exertional right ventricular function in healthy individuals.

This study is to evaluate brain and kidney injuries in full-term neonates with perinatal asphyxia by detecting specific biomarker in blood (Erythropoietin).

The aim of this study is to determine the accuracy of devices called pulse oximeters, which measure blood oxygen by shining light through fingers, ears or other skin, without requiring blood sampling. Study will be used with patients during controlled motion.
