  • Page 127: A Theory Of Operations

    A Theory of Operations Device Description The Newport™ e360 ventilator employs a dual PSOL gas delivery system (one each for air and oxygen), a PSOL-controlled active exhalation valve, and a combination control panel interface and touch screen interface/graphics monitor (GUI). The electronically controlled inlet gas mixing system is superior to traditional pneumatic mixers that must exhaust gas from the system to consistently deliver precise oxygen concentrations.

  • Page 128: Mandatory Breath Types

    Theory of Operations The exhalation system is heated to prevent moist exhaled gas from condensing in the exhalation pathway. A bacteria filter should be used at the From Patient port to prevent contaminants in the exhaled gas from entering the exhalation system and contaminating the exhalation valve and flow sensor.

    Mandatory Breath Types Figure A-1.  Square Waveform in VCV A descending ramp flow wave pattern delivers the set flow initially, decreases flow rate at a constant rate until 50% of the initial flow is reached, and then terminates flow delivery when the set tidal volume has been delivered.

    Theory of Operations the option of unrestricted spontaneous breathing even while pressure in the circuit is elevated to the pressure limit level. This type of ventilation is referred to as Biphasic Pressure Release Ventilation (BPRV)*. It is considered to be more comfortable for patients with an active respiratory drive who are ventilated with Pressure Control.

  • Page 133: Ventilation Modes

    Ventilation Modes by-breath by the ventilator at the lowest level possible between 5 cmH O/mbar above PEEP/CPAP and the pressure limit setting in order to try to achieve the set tidal volume. The set tidal volume is not guaranteed for each breath; it is a target. The target pressure of the first breath, when no target pressure has been established, is PEEP/ CPAP+5 cmH O/mbar.

  • Page 134: Simv

    Theory of Operations The Resp Rate (respiratory rate) setting determines the minimum number of time-triggered or patient-triggered mandatory breaths delivered each minute. The Trig setting determines the airway pressure or airway flow threshold that the patient’s effort must reach in order to trigger these and additional mandatory breaths.

  • Page 135: Spont (Spontaneous

    Safety Features SPONT (Spontaneous) A.4.3 In SPONT, all breaths delivered to the patient are spontaneous breaths.

  • Page 138: Exhalation System

    Theory of Operations The regulated gas enters the PSOL valves, which are designed to supply gas to the patient circuit at the preset or ventilator managed flow. A PSOL valve calibration creates a lookup table of the currents required to generate the range of flows from the PSOL valve. The lookup table allows the ventilator to target the required flow as quickly as possible, and feedback from the flow sensor every 10 milliseconds allows the ventilator to refine flow delivery.

    Theory of Operations Electronics A.6.3 Power to the ventilator enters the AC inlet, which connects to the power supply. The power supply converts alternating current to direct current, and accepts any voltage or frequency within the specified range.
