In-Circuit Module Permits Mobile Anesthesia Delivery

A new mobile anesthesia device delivers inhalation anesthesia in the operating room (OR), intensive care unit (ICU), and even in the field during military operations or disasters.

The Thornhill Medical (Toronto, Canada) MADM in-circuit anesthesia delivery device is designed to make patient anesthesia delivery simpler to monitor and control. While standard anesthesia machines are out-of-circuit devices composed of a complex array of mechanical, electrical, and software-controlled components, the MADM digital device is an in-circuit device that can be added to any ventilator to turn it into an anesthesia machine, with the same vaporizer delivering Isoflurane or Sevoflurane.

Benefits include faster and safer induction, with no need to overpressure the circuit; a rate of induction independent of fresh gas flow; optional use of a reflector to improve efficiency of anesthetic delivery; and faster operator training. The MADM device also serves as a comprehensive anesthetic monitoring device, with information available on anesthetic agent and concentration delivered, end tidal anesthetic concentration, respiration rate, respiratory minute volume (VE), partial inspired CO2 pressure (PICO2), and partial end-tidal carbon dioxide (PETCO2).

“We are extremely pleased to provide a new breakthrough in anesthesia delivery. Our MADM device and be added to any ventilator to create a portable anesthesia machine,” said Kipton Lade, president and CEO of Thornhill Medical.
