Background. Many deaths from attacks of asthma may be preventable. However, the difficulty in preventing fatal attacks is that not all the pathophysiologic risk factors have been identified. Methods. To examine whether dyspnea and chemosensitivity to hypoxia and hypercapnia are factors in fatal asthma attacks, we studied 11 patients with asthma who had had near-fatal attacks, 11 patients with a...

background : foreign body aspiration is a common medical emergency among children that can lead to lethal complications especially in neglected or misdiagnosed cases. case report: this article is a report of a 15-month-old child who aspirated food materials and after chocking crisis, she presented with unspecific respiratory symptoms and treated for respiratory tract infections. after five days...

Carbon monoxide (CO) is a colorless, odorless gas produced as by-product of the complete combustion hydrocarbons. CO binds rapidly to Haemoglobin (Hb), leading formation carboxyhemoglobin (COHb), so oxygen-carrying capacity blood will be decreased and causing tissue hypoxia. We present case accidental carbon poisoning in family where four members were reported dead three unconscious morning aft...

Circadian regulation is critically important in maintaining metabolic and physiological homeostasis. However, little is known about the possible influence of the clock on physiological abnormalities occurring under pathological conditions. Here, we report the discovery that hypoxia, a condition that causes catastrophic bodily damage, is gated by the circadian clock in vivo. Hypoxia signals conv...

ABSTRACT Happy Hypoxia is one of the symptoms Covid-19 that often not known by society. This condition found in cases with very low oxygen levels blood. can be fatal failure several organs body. The purpose this study was to determine relationship between incidences happy hypoxia suspected patients a history cardiovascular disease at ER Panti Waluya Hospital, Malang. design cross sectional tota...

macrophages accumulate in poorly vascularised and hypoxic sites including solid tumours, wounds and sites of infection and inflammation where they can be exposed to low levels of oxygen for long periods. up to date, different studies have shown that a number of transcription factors are activated by hypoxia which in turn activate a broad array of mitogenic, pro-invasive, pro-angiogenic, and pro...

The effects of drowning, both fatal and non-fatal, on the different major organ systems within the body, and the process of hypoxia are reviewed. Pulmonary fluid aspiration results in an increase in low ventilation-perfusion ratio areas and decreased compliance. However, in most victims variable quantities of the liquid medium are aspirated. It is believed that in at least 10% of drowned people...
