Suicide by helium inhalation inside a plastic bag has recently been publicized by right-to-die proponents in "how to" print and videotape materials. This article reports a suicide performed according to this new and highly lethal technique, which is also a potentially undetectable cause of death. Toxicology information could not determine helium inhalation, and drug screening did not reveal dat...

Measurements of cerebral blood flow (CBF) were performed using the microsphere technique in non-human primates (baboons) to assess the effect of non-radioactive xenon gas inhalation on CBF. Blood flows in small tissue volumes (approximately 1 cm3) were directly measured before and during the inhalation of xenon/oxygen gas mixtures. The results of these studies demonstrated that when inhaled in ...

Abstract This study focuses on the evolution of radon concentrations in tap water samples primary schools Najaf city using a RAD-7 detector. Annual effective doses children were calculated. A Geographic Information System technique was used for mapping concentrations, annual dose (AED) ingestion, and inhalation. It found that average value AED due to ingestion 0.236 ± 0.020 μSv/year, while 0.01...

1. The literature concerning inhalation infection with Coccidioides immitis is briefly reviewed. 2. A laboratory technique for exposing animals to inhalation of the spores of Coccidioides immitis is described. 3. Primary pulmonary infection was produced in 42 per cent of 72 animals exposed by this method. 4. No marked weight loss was apparent in the animals infected. 5. Skin tests with coccidio...

A patient with migraine who had a permanent visual field defect was studied by angiography and CT scan. He also had a tomographic study of cerebral blood flow (CBF) and oxygen extraction fraction (EO2) using the non-invasive continuous oxygen-15 (15O) inhalation technique. Angiography was normal. CT scan revealed an area of decreased density with contrast enhancement suggestive of a recent infa...

The article describes a clinical case of inhalation therapy with high doses nitric oxide (NO) in comorbid patient severe course COVID-19. An air stream containing NO was generated using the PLAZON device. High-dose administered as life-saving option due to lack effect from treatment delivered accordance current national guidelines for safety and efficacy technique demonstrated.

The regional cerebral metabolism-to-perfusion imbalance has been studied in the three main categories of cerebrovascular disorders in a chronic phase of the disease, using the non-invasive oxygen-15 inhalation technique. In patients presenting with a history of transient ischaemic attacks, regional defects in cerebral perfusion were greater than for the corresponding oxygen uptakes. Areas of re...

OBJECTIVES Inhalation therapy is the main treatment for asthma and its adequate use has been a factor responsible for disease control; therefore, the aim of the study was to determine whether a digital media tool, which features portability on mobile phones, modifies the assimilation of the inhalation technique. METHODS A total of 66 professionals working in the health care area with the pedi...

BACKGROUND Organic dusts may cause inflammation in the airways. This study was performed to assess the usefulness of the induced sputum technique for evaluating the presence of airways inflammation using inhaled endotoxin (lipopolysaccharide) as the inducer of inflammation. METHODS To characterise the inflammatory response after inhalation of endotoxin, 21 healthy subjects inhaled 40 microgra...

BACKGROUND We previously reported that inhaled nitric oxide (NO) improved pulmonary function following smoke inhalation. This study evaluates the physiologic mechanism by which inhaled NO improves pulmonary function in an ovine model. METHODS Forty-eight hours following wood smoke exposure to produce a moderate inhalation injury, 12 animals were anesthetized and mechanically ventilated (FIO2,...
