UC San Diego Researchers Oxygenation Connections the Brain
2017/11/23
Scientists have known that areas of the brain with similar functions—even those in different brain hemispheres—connect to share signals when the body rests, but they haven’t known how this “resting-st...
Effects of Sprint Interval Cycling on Fatigue, Energy, and Cerebral Oxygenation
HIGH-INTENSITY INTERVAL CYCLING MOOD STATE NEAR-INFRARED SPECTROSCOPY
2017/4/13
Introduction: Feelings of fatigue are reduced after a session of continuous exercise of low-to-moderate intensity lasting 20 min or more, but only when feelings of energy are increased. Feelings of fa...
Effect of Moderate Altitude on Peripheral Muscle Oxygenation During Leg Resistance Exercise in Young Males
NIRcws muscle oxygenation moderate altitude parallel squat SpO
2015/3/13
date is available on peripheral muscle oxidative metabolism at this altitude (1800AL). The purpose of this study was to determine whether acute exposure to 1800AL alters muscle oxygenation in the vast...
The continuing desire to improve performance, particularly at the national and international levels, has led to the use of ergogenic aids. Ergogenic aids are defined as “a procedure or agent that prov...
Evaluation of Intra-Musclar Oxygenation During Exercise in Humans
Near infrared spectroscopy muscle oxygenation
2015/3/10
Near infrared spectroscopy (NIRS) has been frequently used to assess intra-muscular oxygenation past few decades. In recent years, refinement of NIRS hardware and algorithms used to convert changes in...
A Comparison of Effects of Propofol and Isoflurane on Arterial Oxygenation Pressure, Mean Arterial Pressure and Heart Rate Variations Following One-Lung Ventilation in Thoracic Surgeries
Propofol Isoflurane Arterial One Lung Ventilation Arterial Pressure Heart Rate
2015/10/10
Background:: Hypoxia occurs during one-lung ventilation (OLV) due to the arteriovenous shunt of unsaturated pulmonary venous blood. Hypoxic pulmonary vasoconstriction (HPV) acts as a defense mechanism...
Influence of Postexercise Cooling on Muscle Oxygenation and Blood Volume Changes
RECOVERY THERMOREGULATION ADAPTATION CRYOTHERAPY COLD WATER IMMERSION NEARINFRARED SPECTROSCOPY
2017/7/17
Purpose: The aim of this study was to investigate the effects of postexercise cold water immersion (CWI) on tissue oxygenation and blood volume changes after intense exercise.
Methods: Nine physicall...
End Organ Recovery and Survival with the QuadroxD Oxygenator in Adults on Extracorporeal Membran Oxygenation
Extracorporeal Membrane Oxygenation Adults End-Organ Recovery
2013/2/20
Introduction: Extracorporeal Membrane Oxygenation (ECMO) is used in selected patient with cardiogenic and/or re- spiratory shock. We report our experience with standardized management protocols and th...
Effect of propranolol on brain electrical activity during hyperbaric oxygenation in the rat
drug brain electrical activity propranolol oxygen toxicity animal rat
2009/7/14
The effect of 1, 2, and 5 mg/kg propranolol on the neuroelectrophysiological manifestations of CNS oxygen toxicity was studied in conscious rats. Cortical electrodes for electrocorticographic (ECoG) r...
Hyperbaric oxygenation decreases blood flows in normal and septic rats
HBO hyperbaric septic animal rat
2009/7/8
The purpose of the study reported here was to characterize the effects of acute exposure to 100% oxygen at a pressure of 202.6 kPa on hemodynamics and organ blood flow in antibiotic-controlled bacteri...
Skeletal muscle metabolic enzymes are altered by hyperbaric oxygenation treatments
HBO Skeletal muscle metabolic enzymes rabbit animal
2009/6/12
To test whether repeated HBO exposures would increase activity of skeletal muscle metabolic enzymes, 27 rabbits (3 groups) were exposed 90 min/day, 5 days/wk to either 100% O2 at 243 kPa (HBO), 100% O...
Hyperbaric oxygenation treatments and metabolic enzymes in the heart and diaphragm
hyperbaric treatments diaphragm enzymes
2009/6/12
We previously found that intermittent hyperbaric oxygen exposure increases metabolic enzyme activity in soleus muscle. Since the metabolic enzyme activities of the heart and diaphragm of healthy anima...
Influence of delayed hyperbaric oxygenation on recovery from mechanically induced damage
hyperbaric recovery Influence
2009/6/12
This study examined whether subjecting a crushed muscle to a delayed intermittent hyperbaric oxygenation protocol would facilitate healing, the marker for healing being a return toward 100% uncrushed ...
Non-comatose patients with acute carbon monoxide poisoning: hyperbaric or normobaric oxygenation?
carbon monoxide HBO hyperbaric cerebral blood flow normobaric
2009/6/12
Twenty-six non-comatose patients with acute carbon monoxide (CO) poisoning were randomized into two groups. Both groups were treated as soon as possible and for 2 h, the first group by 100% normobaric...
Retinopathy of prematurity (ROP) usually occurs after a prolonged exposure to normobaric hyperoxia in newborn mammals and infants. We hypothesized that experimental ROP also could develop after acute ...
