Options include an Aerogen Aeroneb nebulizer, data capture accessory and an integrated air compressor. Options available on Engström Carestation only include integrated respiratory gas monitoring capabilities via various Datex-Ohmeda patient monitoring modules listed in the product labeling, capabilities to measure SpiroDynamics via an intratracheal pressure sensor in patients using sized 6.5 tracheal tubes and larger, and calculation of functional residual capacity of mechanically ventilated patients using Nitrogen Wash In/Wash Out method. Not all features are available with all patient populations. The Engström Carestation is not a pulmonary function calculation device. The system is designed for facility use, including within-facility transport, and should only be used under the orders of a clinician.

The GE Datex-Ohmeda Engström family of ventilators (Engström Carestation and Engström Pro) are flexible, adaptable, and intuitive critical care ventilators. A wide selection of performance options gives the user full control of the system configuration. The Engström Carestation is a complete system featuring patient monitoring, patient ventilation, and the capability of interfacing with central information management systems. The Engström Pro is a defeatured variant of the Engström Carestation. Both the GE Datex-Ohmeda Engström Carestation and Engstrom Pro are designed to provide mechanical ventilation for adults and pediatrics weighing 5kg and above having degrees of pulmonary impairment varying from minor to severe. Optional Neonatal capabilities expand its patient range to 0.25 kg. The modes of ventilation currently available include: 1. Volume Controlled (VCV) 2. Pressure Controlled (PCV) 3. Pressure Controlled, Volume Guaranteed (PCV-VG) 4. Synchronized Intermittent Mandatory Ventilation, Volume Controlled (SIMV-VC) 5. Synchronized Intermittent Mandatory Ventilation, Pressure Controlled (SIMV-PC) 6. Synchronized Intermittent Mandatory Ventilation, Pressure Controlled Volume Guarantee (SIMV-PCVG) 7. Bi-level Airway Pressure Ventilation 8. Constant Positive Airway Pressure/Pressure Support Ventilation (CPAP/PSV) 9. Apnea backup (active in Bi-level and CPAP/PSV) 10. Non-invasive ventilation (NIV), note that NIV is not available in neonatal mode 11. Infant Nasal CPAP (nCPAP) 12. Volume Guarantee, Pressure Support (VG-PS) The GE Datex-Ohmeda Engström Carestation and Engström Pro are microprocessor based, electronically controlled, pneumatically driven ventilators that include integrated FiO2, airway pressure, spirometry and volume monitoring and an Aerogen Aeroneb Pro nebulizer control board. The ventilator consists of two main components: a display and a ventilator unit. The display allows the user to interface with the system and control settings. The ventilator unit controls electrical power, nebulization, and pneumatic gas flow to and from the patient. The Engstrom Carestation also includes a module bay that allows the integration of various Datex-Ohmeda patient monitoring modules with the ventilator. The user interface for control of nebulization is provided via the ventilator display unit. The Aerogen Aeroneb Pro Nebulizer board (K021175) is provided standard with the unit. Nebulizers are options for both the Engstrom Carestation and Engstrom Pro. Users have the option to configure the system to use an external pneumatic nebulizer in place of the Aerogen. Optional accessories common to both Engström Carestation and Engström Pro include a trolley/cart, integrated air compressor, support arm, humidifier and water trap mounting brackets, and a data capture accessory. The GE Datex-Ohmeda EV Air Compressor is intended for use as an accessory to provide a dry, filtered, breathable compressed air supply. The compressor has no alarm functions. The Engstrom Carestation or Engstrom Pro provides all alarm functions and reactions to a failure of the compressed gas supply. The compressor is installed in the base of the ventilator cart. The compressor is powered from AC mains only. A source of compressed oxygen is required to be connected to Engstrom Carestation/Engström Pro equipped with the optional compressor. The compressor was cleared in K041775. Additional optional accessories specific to the Engström Carestation include airway modules, intratracheal pressure sensor, auxiliary electrical outlets, and module bay. Optional functionality specific to the Engstrom Carestation include integrated respiratory gas monitoring, capabilities to measure SpiroDynamics via a GE supplied intratracheal pressure sensor in patients using sized 6.5 tracheal tubes and larger, and calculation of functional residual capacity of mechanically ventilated patients using Nitrogen Wash Out method. The integrated respiratory gas monitoring is provided via the Datex-Ohmeda M-Gas Module (M-C, M-COV, M-COVX, M-CaiO, M-CAiOV, M-CAiOVX, rev 3.2 software and higher, (K001814) or Mini-CO2 Module (K023454) which are physically integrated into the Engstrom Carestation, receive electronic power from the Engström Carestation and communicate measured values to the Engström Carestation for display on the system display unit.

The family of GE Datex-Ohmeda Aespire anesthesia systems with 7900 ventilator (Aespire 7900 and Aespire View) is intended to provide general inhalation anesthesia and ventilatory support to a wide range of patients. The devices are intended for volume or pressure control ventilation. The devices are not suitable for use in a MRI environment.

The family of GE Datex-Ohmeda Aespire anesthesia systems with 7900 ventilator (Aespire 7900 and Aespire View) is intended to provide general inhalation anesthesia and ventilatory support to a wide range of patients. The systems are to be used only by trained and qualified medical professionals. The Aespire 7900 and Aespire View supply set flows of medical gases to the breathing system. A large selection of frames, gases, and vaporizers are available to give the user control of the system configuration. They are available in trolley and pendant models, with two or three gases, two vaporizer positions and up to three cylinder connections. All models connect to oxygen and can additionally connect with up to two optional gases (air, N2O). The Aespire systems accept Tec 4, Tec 5, Tec 6, Tec 6+ and Tec 7 vaporizers on a Selectatec manifold. Safety features are designed to decrease the risk of hypoxic mixtures and complete power or sudden gas supply failures. The Aespire View family member provides optional electronic Total Fresh Gas Flow (TFS) monitoring. The Aespire View also features a color display, while the Aespire 7900 uses a monochromatic display. The Datex-Ohmeda 7900 Anesthesia Ventilator is used in this family of Anesthesia Systems. It is a microprocessor based, electronically controlled, pneumatically driven ventilator that provides patient ventilation during surgical procedures. The 7900 ventilator is equipped with a built-in monitoring system for inspired oxygen, airway pressure and exhaled volume. Sensors in the breathing circuit are used to control and monitor patient ventilation as well as measure inspired oxygen concentration. This allows for the compensation of compression losses, fresh gas contribution and small leakage in the breathing absorber, bellows and system. User setting and microprocessor calculations control breathing patterns. The user interface keeps settings in memory. The user may change settings with a simple and secure setting sequence. A bellows contains breathing gasses to be delivered to the patient. Positive End Expiratory Pressure (PEEP) is regulated electronically. Positive pressure is maintained in the breathing system so that any leakage that occurs is outward. An RS-232 serial digital communications port connects to and communicates with external devices. Ventilator modes for the device include Volume Control (VCV) Mode, Pressure Control (PCV) Mode (Optional), Synchronized Intermittent Mandatory Ventilation with Pressure Support Ventilation (SIMV/PSV) Mode, Pressure Support with Apnea Backup (PSVPro) Mode (Optional), Synchronized Intermittent Mandatory Ventilation with Pressure Control (SIMV-PC) Mode (Optional), and Pressure Control Ventilation - Volume Guaranteed (PCV-VG) mode (Optional on Aespire View variant only),
