Arterial oxygen and carbon dioxide tensions, pH and forced expiratory volumes were measured in 101 asthmatic patients during acute attacks of bronchospasm. Hypoxemia was observed in 91 subjects. The ...

IN previous articles 1–3 attention was directed to the fact that high pressures of pure oxygen have a specific effect on the metabolism of cells of various kinds. In the tissues of higher plants the ...

ARTERIAL oxygenation during apnea may now be studied with greater accuracy. The recent development of the polarograph 1–3 has made it possible to obtain direct arterial-oxygen-tension determinations ...

Introduction Although pressure support ventilation is one of the most commonly used assisted ventilation modes in intensive care units, there is still a lack of precise strategies for setting pressure ...

While many serious cases of COVID-19 are marked by respiratory distress and dangerously low blood oxygen levels — a condition referred to as hypoxia — the occurrence of “silent or happy hypoxia” ...
