A significant reduction in arterial blood oxygen saturation during fiberoptic bronchoscopy has been proved but it is not yet known whether all patients need supplemental oxygen during this procedure. The aim of study is to examine the relationship between peak expiratory flow rate (PEFR) before bronchoscopy and oxygen desaturation during bronchoscopy. Measurement of PEFR (% predicted) performed...

BACKGROUND In 1994, the American Heart Association Stroke Council concluded that there were no data to support the routine use of supplemental oxygen in patients who had a stroke. More recently, supplemental oxygen has been suggested to be potentially detrimental. The purpose of this study was to determine the extent of oxygen use in ischemic stroke patients and whether patients receiving oxyge...

BACKGROUND The development of portable liquid oxygen systems, capable of delivering high flow rate oxygen for long periods, justifies reassessment of the value of supplemental oxygen to aid exercise tolerance in patients with chronic respiratory insufficiency. The type of exercise test and the low oxygen flow rates previously used may account for the variable and often poor responses to supplem...

introduction: oxygen is a drug and physician and nurses should be familiar with the effects and potential risks of oxygen therapy. the current study aimed to assess familiarity of physicians and nurses with various aspects of oxygen therapy. method: in this cross sectional study, the familiarity of physicians and nurses with various aspects of oxygen therapy in a teaching hospital was evaluated...

CONTINUOUS POSITIVE AIRWAY PRESSURE (CPAP) IS CONSIDERED TO BE THE MOST EFFECTIVE AND THE PREFERRED THERAPY FOR OBSTRUCTIVE SLEEP apnea (OSA). In placebo-controlled and uncontrolled studies, CPAP has been shown to correct the elevated apnea-hypopnea index (AHI) and the transient desaturations associated with respiratory events during sleep.1-4 In uncontrolled studies, CPAP has also been shown t...

the management of road traffic accident and the care of casualties  has undergone many changes in recent years. to provide an uniform and systematic approach the ems, firefighters, red cross, red crescent and other rescuers must be updated to reduce entrapment times, and mortality rates, over better organisation and a methodical approach. the rescuers should not attempt to administer medical fi...

background oxygen therapy, as a therapeutic modality, can be used for long periods of times. however, it may be accompanied by potential complications and side effects. objectives to evaluate the side effects of normobaric oxygen therapy in rabbits. materials and methods in a double-blind experiment, 28 white new zealand rabbits were randomized into an oxygen treatment group (n = 14) and a cont...

Therapy for severe chronic lung disease currently includes the administration of supplemental oxygen to prevent breathlessness and tissue hypoxia. Although effective, this therapy is unnecessarily costly, because oxygen is administered to the patient during expiration as well as inspiration. To eliminate this inefficiency, a delivery system that senses the inspiratory effort and delivers oxygen...
