Siemens Maquet Servo-i Features

The Maquet Servo I ventilation system can be used on a variety of patients from neonatal, pediatrics, and adults. It has the ability to handle the most acute phases of respiratory distress, through recovery, and to the waning phases of the ventilation process. The Servo-i continuously delivers outstanding ventilator treatment as gently as possible. This is in part due to the performance, monitoring capabilities, treatment options, and tools that this ventilator offers. Since this ventilator can be used on a wide variety of patients, it is suitable for most environments from the ICU to the NICU department. The Maquet Servo-i ventilator allows you to choose the treatment option based on your patients’ needs without having to worry about the ventilator’s capabilities.

Servo-i supports both invasive and non-invasive ventilation. It combines the highest level of clinical performance with outstanding mobility and cost-efficiency. Ease of training, operation, and maintenance, as well as flexibility and modularity, ensures a low life-cycle cost. The economic benefits of operating this modular platform are considerable: there is no need to scrap and reinvest for different patient categories and situations.

The Servo I ventilator is easy to use and learn about. The ventilation system provides the information you need, when you need it, allowing a fast and appropriate response from the user. The user-friendly interface gives easy access to all settings and even reaches the most important parameters through direct access knobs. This way, the clinician is always informed, in control, and able to react.

The Servo-i ventilation system is an all-in-one platform with advanced features you would normally expect from an advanced system. In patients with ALI and ARDS, it is difficult to identify harmful ventilator patterns, most importantly Barotrauma. The adult and universal Servo-i configurations have a feature called Stress Index that helps clinicians detect and prevent potentially high-risk scenarios in adults. The ventilator analyzes changes in the compliance of the respiratory system during the constant flow of controlled breaths. This unit also has a Heliox option which is a low-density gas mixture of helium and oxygen. Heliox is widely recognized as a therapy that minimizes turbulence and improves CO2 elimination.

This ventilator is designed to meet your clinical needs. It’s a single system that offers a broad range of treatment options, which means it is always ready to adapt to your changing medical needs. This ventilator comes in 3 different configurations; infant, adult, and universal. The infant configuration doesn’t have the Stress Index and the Hyperbaric Oxygen Therapy (HBO) feature. The Adult configuration doesn’t have the Nasal CPAP or the HBO feature. If you are interested in knowing exactly what features each configuration has, call 1-800-GET-SOMA and one of our knowledgeable sales representatives will assist you.
