Intended Use

The GE Datex-Ohmeda Engström family of ventilators (Engström Carestation and Engström 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 on Engström family expand the patient range to 0.25 kg.

The GE Datex-Ohmeda Engström family of ventilators are microprocessor based, electronically controlled, pneumatically driven ventilators that include integrated FiO2, airway pressure, spirometry and volume monitoring. 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.

Device Description

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.

AI/ML Overview

This document is a 510(k) premarket notification for the GE Datex-Ohmeda Engström Ventilator, seeking substantial equivalence to previously cleared devices. It does not contain information about acceptance criteria or a study proving the device meets specific performance criteria through clinical data.

Specifically, the document states:

  • "The modifications made to the Engstrom ventilator did not require clinical testing."

Therefore, I cannot provide the requested information regarding acceptance criteria and a study proving the device meets those criteria, as no such clinical study data or acceptance criteria related to a performance study are present in the provided text. The submission focuses on verification of specifications, validation (including software validation), electrical safety, and electromagnetic compatibility testing, rather than a clinical performance study with defined acceptance criteria for AI or a detailed comparison of device performance against a benchmark.

§ 868.5895 Continuous ventilator.

(a)
Identification. A continuous ventilator (respirator) is a device intended to mechanically control or assist patient breathing by delivering a predetermined percentage of oxygen in the breathing gas. Adult, pediatric, and neonatal ventilators are included in this generic type of device.(b)
Classification. Class II (performance standards).
