DefiMonitor XD Defibrillator

The new PRIMEDIC biphasic defibrillation technology has been integrated in the DefiMonitor XD generation. The defibrillation pulse generated by a current-controlled pulse output stage, excludes current peaks that are damaging to cardiac muscle. The delivered energy is calculated in the automatic mode on the basis of body resistance, which ensures a high success rate by means of patient-specific treatment. The user can also exercise full control over the defibrillation energy in the manual mode, if required. The current changes its direction within a defined period of time (biphase). This feature facilitates a gentle and exceedingly effective defibrillation procedure.

 

Easy operation for the highest demands!

 

METRAX has been analysing experiences of users in clinics and rescue services for years. This know-how is concentrated in the DefiMonitor XD, making it ideally configured for routine medical application. Its modern design is characterised by an extremely robust casing, powerful technology and very easy operation. This permits effective action even in extreme situations. The full range of functions of the DefiMonitor XD coupled with its low weight, make it an ideal device for use in emergency medicine.

 

User friendly operation – very powerful technology.

 

Concentrate on the emergency while relying on DefiMonitor XD. DefiMonitor XD is also equipped with a mounting fixture and a charging system, allowing it to be positioned wherever it is needed. Top performance is not necessarily expensive, as you will be pleased to find out when making an inquiry. The DefiMonitor XD product family – practical help for all circumstances!

 

DefiMonitor XD - Know-how all the way to the paddles

 

Quick and easy: Defibrillation electrodes for children are always available at the emergency site. An innovative mechanism allows conversion of the adult electrodes into children’s electrodes in no time at all. This makes sure that the children’s paddles are where they should be at all times – on the DefiMonitor XD. The ergonomically shaped paddles make sure that you have a good grip with maximum capacity performance.

 

Easy to handle, reliable and well-proven in practice.

 

Light weight and easy to handle make working with the DefiMonitor XD very pleasant and comfortable. The removable memory cards of the new DefiMonitor XD family now provide the option of transferring all recorded ECG data to any regular PC for archiving – simple and uncomplicated. Free selection of a voice recording option is standard for all XD products and can be used for evaluation purposes if you wish. All 6 ECG channels can be selected independently from each other – you choose which 2 curves you wish to view on the monitor. For additional patient monitoring security, the XD products are optionally equipped with an integrated Nellcor SpO2 pulse oximeter. Cutting edge technology. The DefiMonitor XD product family – certainly the right choice for you and your patients!

 

Also there is mo problem in Harsh conditions.

 

Unfavourable light conditions are no problem for DefiMonitor XD with its large and high-contrast BlueMode TFT-LC-Display (115 mm x 86 mm). This ensures an optimal and reliable view of the monitoring process, even in bright light conditions. The transthoracic pacemaker (NIP) supplements or takes over stimulation of the cardiac muscle in emergencies. Application under difficult conditions requires reliable and extremely stable equipment. Shock-absorbing interior lining and an unbreakable plastic casing protect the DefiMonitor XD. The technical equipment inside is isolated from damage due to blows or unfavourable weather, ready for use and functioning perfectly under all conditions.

 

During the defibrillation the operating modes are asynchronous, external in auto/manual mode. It has a synchronisation only in manual mode, with a biphasic current controlled (CCD).
