Oxygen Treatment may be injurious

According to a recent survey it is observed that breathing oxygen may cause some harm to cells. The oxygen cylinder is a familiar sight around the beds of people //with severe lung or heart disease.Oxygen supports the organs of the body when the heart can't deliver enough through the blood. But oxygen is often given inappropriately. Overall the fact to believed is that Oxygen is the 'breathe of l...

Oxygen helps heal wounds

A recent study has has shown that oxygen, apart from breathing life into lungs, also helps heal wounds. Prior studies have shown that oxygen plays an important role in helping the body heal, after injury. In fact, studies have shown treatment in a hyperbaric oxygen chamber can help wound healing. However, hyperbaric therapy is expensive and there are doubts about whether or not it causes oxygen t...

Oxygen Usage During Exercise Could Indicate Heart Problems

Cooling Can Reduce The Risk Of Brain Damage In Oxygen Deprived Newborns

Newborns deprived of oxygen can have a reduced risk of brain damage and cerebral palsy by having their brains cooled // for 72 hours after birth according to a recent study. ..Babies that received an inadequate supply of oxygen to the brain during delivery showed signs of being at a high risk for brain injury. However researchers say brain damage does not happen immediately when babies are oxyge...

Air travel reduces oxygen level in the blood

In a recent study made by researchers of UK, scientists have found that traveling by air seemed to lower the //oxygen level in the blood of the passengers. ....The study was done to see whether air traveling, which has become so commonplace today, do have any effect on the health of the passengers flying today. The researchers have taken the measurement of peripheral oxygen saturation and pulse r...

Influence Of Heart Rate On Myocardial Oxygen Tension

The influence of heart rate on cardiac output, oxygen consumption, and myocardial activity has been widely investigated.// However, the influence of heart rate on myocardial oxygen tension (pO2) remains unclear. Since the introduction of flexible pO2 micro catheters to measure partial oxygen tension in a working muscle, it is possible to investigate the influence of heart rate on myocardial oxyge...

Mobilizing Stem Cells at the Injured Site Using Hyperbaric Oxygen Treatments.

The research was done by Stephen Thom, MD, Ph.D., Professor of Emergency Medicine at the University of Pennsylvania, School of Medicine. // ..He said that a course of hyperbaric oxygen treatments would increase the number of circulating stem cells in the body of the patient. ..Stem cells are progenitor cells which are totipotent and pluripotent meaning that they have the ability to differentiat...

Stem cells mobilized by hyperbaric oxygen

Hyperbaric oxygen treatments boost tissue repair and recovery from injury tissue by increasing the number of circulating stem cells, according to a new study // . ..The report, to be published in the April 2006 issue of American Journal of Physiology-Heart and Circulation Physiology, says a typical course of hyperbaric oxygen treatments increases the number of stem cells circulating in a patient`...

New Sensor To Monitor Oxygen Deprivation In Babies During Birth

A new device developed to detect elevated levels of hypoxanthine (a chemical) can alert physicians about oxygen deprivation in a baby during childbirth. // This finding is hoped to reduce the number of Caesareans being performed, as any suspicion of oxygen deprivation is a strong indication for the surgery. ....The medical device, developed by researchers at Warwick University has been named th...

Oxygen Shortage Causes Panic Among Patients

Regular oxygen supplies are facing a setback, after four private companies took over the reins of the contract, from NHS Service, in February, this year. This has created huge problems for patients for whom oxygen supply can mean the difference between life and death. //It is estimated that about 60,000 people are in need of oxygen at home for various life threatening problems. ..Home deliverie...

Oxygen-Induced Damage A Leading Cause For Parkinson’s Diseas

Cellular damage induced by oxygen free radicals may be one important factor contributing to Parkinson’s disease, reports a new study. //This groundbreaking study conducted by neuroscientists at the University of Virginia Health System highlights that damage of complex I, a protein that plays a major role in the electron transport chain inside the mitochondria has been blamed for cellular damage i...

Heart Has Enough Oxygen to Survive Hypothermia; CPR Crucial

Researchers from Norway may have ruled out insufficient oxygen supply to the heart as the critical variable in whether a mammal’s heart survives while in a hypothermic state.// ....Writing in the July issue of the American Journal of Physiology-Heart and Circulatory Physiology, researchers found no significant difference in the amount of oxygen available to the heart between rats exposed to one...

Women Are More Likely To Die Than Men When On Oxygen Therapy
