Anesthesia Monitors: What to Know

Any procedure that requires the use of anesthesia needs to be done with an anesthesia monitor to ensure that the patient is safe. These machines monitor the delivery of medications, fluids, and gases and display the patient’s physiological state. Anesthesia drugs alter how the body functions, so there are risks involved with its use during various procedures. However, if the vital signs of the patient are monitored continuously, there is a reduction in the overall risks associated with the procedure.

The use of anesthesia in a medical procedure induces a temporary loss of awareness or sensation. It is used to provide a painless procedure for a patient, where the procedure would normally cause them severe discomfort or pain. There are some medical concerns when patients are in this state, so it is important to be able to monitor their vitals throughout the procedure. Choosing the right anesthesia monitor is a good way to ensure that the monitor provides the information needed for various procedures. Here are three of the top monitors on the market:

Invivo M12 Basic

Invivo’s M12 Anesthesia Monitor is a complete system that can collect process, analyze, and display patient’s data from up to nine parameters that the user can select. This allows the monitor to cater to the individual needs of the patient. The parameters are easy to access and can be used in multiple areas, such as, recovery rooms, operating rooms, critical care units, and emergency rooms.

Up to six valuable pieces of information may be displayed on the flat display screen, so that the physicians can keep track each of the key values simultaneously. It provides a more complete idea regarding the patient’s condition and allows for versatility in its use. Additionally, the unit is compact and comes with batteries that provide for alternative power source in an emergency or during transport.

GE Datex Ohmeda Cardiocap/5

Ge’s Datex Ohmeda Cardiocap/5 is an all-in-one unit that is compact and easy to transport. It is design for use in induction rooms, PACUs, ambulatory surgery units, and operating rooms. The Cardiocap/5 provides for full monitoring capabilities of vital signs from circulation and oxygenation to ventilation measurement and airway gas analysis. The user interface is a trademark of GE and makes it easy to learn and use and works with all anesthesia machines.

The panel unit provides a large font display for better visibility from a distance. Therefore, it provides for a useful tool to allow everyone with a clear view of the vitals. With a back-up battery for emergencies and a frame mounted piece, the unit is easy for transporting patients. The unit can be easily mounted on the wall, an anesthesia mounting arm, or a roll stand.

Datex Ohmeda S/5

The Datex Ohmeda S/5 monitor is a modular unit, so that it can be upgraded at any time. The highly flexible unit is easy to configure for multiple uses throughout the facility. The central displays and units separate into various components. With four display options and integrated monitor controls, the unit offers the ideal features for different circumstances. It is easy to monitor a patient’s vital signs with up to eight wavelengths on the screen at one time.

Datex Ohmeda S/5 has an automatic limits alarm, anesthesia dedicated alarm, user-configurable modes, with cardiac bypass mode, split screen capability, and open hardware and software architecture. This machine is designed to be versatile and works as a modular unit, so that it works seamlessly with other monitoring systems.

Monitoring patients during surgery, recovery, or transport is vital to understanding whether serious risks involving the patient’s health exist. The monitoring systems track vital signs that help the doctors know whether these signs move out of the normal threshold. These monitoring systems are designed to provide important information when it is needed and allow for it to be determined wherever it is needed, as well.
