sedation.4.11.1 Equipment for inhalation sedation with oxygen-nitrous oxide gas mixture
The most widely used equipment for inhalation sedation is the Quantiflex MDM (Fig.
4.3), which enables the operator to deliver carefully controlled volumes and
concentrations of gases to the patient. In addition to the machine head that controls
the delivery of gases, it is also necessary to have a suitable scavenging system, and an
assembly for the gas cylinders, either a mobile stand (Fig. 4.4) or a pipeline system
with cylinders stored remote from the machine head (Fig. 4.5).
