HeliumSauerstoffs

HeliumSauerstoffs is a gas mixture of helium and oxygen used in respiratory therapy, commonly referred to in English as heliox. It is typically prepared in fixed ratios such as 80/20 or 70/30 by volume, though other compositions may be used to meet patient needs. The helium component lowers the density and viscosity of the breathing gas compared with ambient air, which can facilitate more laminar flow during breathing and reduce the work required to move air through obstructed airways.

The reduced density of HeliumSauerstoffs leads to less turbulent gas flow in the conducting airways, which can improve ventilation in patients with conditions that narrow or block the airways. Because the mixture contains oxygen, its oxygen content must be carefully matched to clinical requirements to avoid hypoxemia. The gas is generally delivered via a face mask, hood, or endotracheal tube, under medical supervision, and is not intended as a substitute for bronchodilator therapy or definitive treatment of the underlying condition.

Safety and limitations are important considerations. HeliumSauerstoffs should be used only when indicated, as it can alter gas exchange in some patients and may raise carbon dioxide levels if ventilation is inadequate. It is non-toxic and non-flammable, but oxygen-rich environments require caution due to fire risk associated with high oxygen concentrations. The therapy is typically employed as a short-term intervention to alleviate breathing difficulty while other treatments take effect.

Historically, heliox was introduced in the mid-20th century and remains a selective tool in emergency and critical care, particularly for acute airway obstruction and during certain diagnostic procedures.
