About MADM™

A Revolution in Mobile Anesthesia

MADM™ is the world’s first inline direct injection anesthetic vaporiser. Connect it to any ventilator and instantly you can deliver gas anesthesia, safely and accurately, anywhere your mission takes you.


Versatile and Portable

The versatility and portability of MADM™ make it ideal not only in the controlled environments of operating rooms, intensive care units and medical clinics, but also for delivering gas anesthesia in more challenging environments such as field hospitals and forward-deployed surgical operations.


Safe and Economical

MADM™ is very economical in its consumption of liquid anesthetic, and automatically adapts its operation to the type of ventilator it is connected to. In a circle-circuit configuration, MADM™ automatically reduces its vaporization rate to compensate for unused anesthetic returning from the patient, resulting in a substantial reduction in liquid anesthetic consumption.

Intended Use

MADM™ is intended to deliver volatile anesthetic to a patient when placed in either circle or open anesthetic circuits. It vaporizes isoflurane and sevoflurane and delivers the vaporized anesthetic agent into the inspiratory limb of the breathing circuit.


MADM™ is also intended to monitor respiratory rate, CO2, and the anesthetic gases isoflurane and sevoflurane. It is intended to be connected to a patient breathing circuit for monitoring of patients to whom it is delivering volatile anesthetic gases. MADM™ is not indicated for use with a carrier gas containing nitrous oxide.

Intended Environments

MADM™ is intended to be operated in hospitals. MADM™ is not intended to be used during patient transport.

Intended Use Population

The intended patient population is adults who weigh 40 kg (88 lbs) or more.


MADM™ is subject to any contraindication to inhaled anesthetics.
