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
Safety and limitations are important considerations. HeliumSauerstoffs should be used only when indicated, as it can
Historically, heliox was introduced in the mid-20th century and remains a selective tool in emergency and critical
