• Page 15: What Is An Engström Carestation

  The Engström Carestation (EC) is a critical care ventilator that is flexible and physically adaptable to a variety of work environments. It has an intuitive user interface that is common to many Datex-Ohmeda products. A wide selection of performance options gives the user full control of the system configuration.

• Page 16
  Engström Carestation The system is designed for facility use, including within-facility transport, and should only be used under the orders of a clinician. It is designed to be operated on medical-grade gases only and should never be connected to gasses that do not meet the medical-grade requirements listed in Appendix A. The Engström Carestation consists of three main components: a display, a ventilator unit, and an optional module bay.

  2 Theory of Operation In this section 2.1 Pneumatic Operation …………2-2 2.1.1 Primary Gas Inlet .

• Page 28: Pneumatic Operation

  Engström Carestation 2.1 Pneumatic Operation For a complete diagram of the pneumatic system, refer to Figure 11-3, «Vent Engine manifold flow diagram» in Section11. The EC requires medical-grade oxygen (O ) and medical-grade Air sources ranging from 2.4 to 6.5 bar (35 to 94 psi). Refer to Appendix For additional information regarding medical-grade gasses.

• Page 29: Primary Gas Inlet

  2 Theory of Operation 2.1.1 Primary Gas Inlet Compressed gas enters the EC through an inlet fitting {2} that is particular to the institution’s supply system. The gas is filtered through a 2-micron particulate filter {3} and then a 0.5-micron coalescing particulate filter {3a} as it enters the ventilator’s “pneumatic engine”…

• Page 30
  Engström Carestation Downstream from the check valve is a 172 kPa (25 psi) pressure regulator {6}. (The regulator is a non-relieving type that does not bleed gas into the ventilator’s enclosure.) The regulator ensures a constant pressure supply to the flow valve {8}. The regulated supply is flow rate dependant, which is compensated for in the flow valve’s on-site calibration.
• Page 31
  2 Theory of Operation Downstream of the flow sensor is a flow valve {8} that meters flows from approximately 0.05 l/min (leakage level) to a full flow value of 160 l/min. The valve is a normally- closed proportional solenoid that is powered by a current feedback loop.
• Page 32
  Engström Carestation Following the two individual flow valves is the total flow sensor {10}. This sensor is the same type as the individual flow sensors and is used to measure the combined inspiratory flow being dispensed from the system. Using the known mixture composition along with atmospheric pressure and gas temperature information, mass-flow data from the sensor is converted to delivered volumetric flow towards the patient.
• Page 33
  2 Theory of Operation Following the total flow sensor are the free-breathing check valve {11} and the inspiratory effort valve {12}. During normal operation, the inspiratory effort valve is open, allowing the free-breathing check valve to admit flow if the patient draws a significant amount of inspiratory pressure, causing the airway pressure to become more negative than -0.5 cm H O.
• Page 34
  Engström Carestation As a safety measure, a relief valve {14}, located downstream from the O sensor, can be energized to vent the full flow rate of the inspiratory delivery side of the system. If an overpressure condition is detected, the valve can be opened by either of the EC’s two control processors.

• Page 35: Expiratory Circuit

  2 Theory of Operation 2.1.2 Expiratory circuit At the expiratory side of the ventilator, a solenoid powered exhalation valve {16} controls exhaust from the breathing circuit. The valve contains an elastomer diaphragm that is held against a rigid seat by a solenoid (voice coil) driven piston.

• Page 36
  Engström Carestation electrically act as variable resistors in each of the bridges. The sensors hold a constant temperature at all times as they contain a linear resistance change with temperature. The Neonatal Flow sensor is connected to the Ventilator Monitoring Board (VMB) through the Motherboard via Port 1 and a 2 meter long shielded cable, detachable at both ends.

• Page 37: Associated Circuits

  2 Theory of Operation 2.1.3 Associated circuits Associated with the inspiratory and expiratory pressure transducers are two “zeroing” solenoid valves {21} and {22}. These valves are used to disconnect the pressure transducers from circuit pressure and vent them to atmosphere during zero bias calibration.

  Notes 2.3.4 Ventilator The VCB is a Motorola Coldfire V4 CPU powered assembly that: Control Board — •collects information from all EC system sensors (some indirectly from the VMB), •and controls all actuators necessary to effect ventilation delivery. he VCB computes and supplies all ventilation sensor monitoring data for display on the DU. If there are alarms to be generated based on this monitoring data, the VCB notifies the DU to post the appropriate alarm message and audio sequence.
