  • Page 4 An explosion or fire may result. Description The NEUMOVENT Graph Ventilator comprises a system of related elements and designated to alter, transmit and apply energy directly, and in a predetermined mode, replacing or contributing with the patient's muscular capacity in the execution of the work of breathing with the intention of achieving an efficient gas exchange.
  • Page 5 In this case, it will control the ventilation. The NEUMOVENT Graph Ventilator is able to control the pressure waveforms like the flow waveforms. This control also can be doing in a single inspiration.
  • Page 6 (pneumotachograph), then the ventilator is classified as a flow controller. The Volume mode of the NEUMOVENT Graph Ventilator uses the flow as the control variable. The Pressure Support mode with Volume Assured is able to change, in oneself inspiratory phase, from pressure controller to flow controller.
  • Page 7 Date: 09/05/06 Principles of Operation Operative definition The NEUMOVENT Graph Ventilator is a pressure or flow controller. The inspiration is triggered by pressure, flow, time or manually. It is pressure, volume or flow limited and pressure, volume, flow or time cycled.
  • Page 8 Review : 04 TECHNICAL AND MAINTENANCE MANUAL Graph VENTILATOR Date: 09/05/06 Control valves The mentioned proportional valves regulate the gas flow to the patient. The flow control is able to send flows up to 180 L/min when the gases are from a central-supply system, and of 120 L/min when a portable compressor provides the air.
  • Page 9 Likewise, the screen shows messages indicating an alarm state or to execute some action. Respiratory cycle The process of insulation of gas to the lungs by means of the mechanic ventilation with the NEUMOVENT Graph Ventilator comprises four steps: 1) Start of inspiratory phase 2) Progression of inspiration...
  • Page 10 Review : 04 TECHNICAL AND MAINTENANCE MANUAL Graph VENTILATOR Date: 09/05/06 The form in the flow administration depends on the ventilatory mode and of the selected flow waveform. In the VCV mode the flow waveforms, which can be selected, are: descending ramp (decelerating), rectangular (continuous flow), sinusoidal, ascending ramp (accelerating).
  • Page 11 Date: 09/05/06 The expiratory phase can be modifying adding Positive Pressure at the End of Expiration (PEEP). The NEUMOVENT Graph Ventilator produces this positive pressure by means of a digital regulation of the closing force of the expiratory valve diaphragm.

  • Page 14 Review : 04 TECHNICAL AND MAINTENANCE MANUAL Graph VENTILATOR Date: 09/05/06 Operative modes According to the described functional characteristics, as well as the controls and limits assigned to this device, the following operative modes have been included. These modes agree with the descriptions of the classic world literature, which is mentioned partly in "Bibliography."...
  • Page 15 Review : 04 TECHNICAL AND MAINTENANCE MANUAL Graph VENTILATOR Date: 09/05/06 Volume VCV Assist/Control Definition and Operative Proceeding: It is a ventilatory mode with specific regulation of the tidal volume. The inspiratory pressure is variable, and it depends on the respiratory impedance to regulated volume. During this mode, the ventilator works as a flow-controller where the selected flow waveform is sustained during any lung compliance/resistance variation.
  • Page 16 Review : 04 TECHNICAL AND MAINTENANCE MANUAL Graph VENTILATOR Date: 09/05/06 lung size, the existent pressure gradient at the beginning of inspiration between the upper airway and the alveoli, the respiratory system compliance and the available inspiratory time. The pressure waveform developed during inspiration is rectangular, being the flow of the descending ramp type (decelerating flow).
  • Page 17 Review : 04 TECHNICAL AND MAINTENANCE MANUAL Graph VENTILATOR Date: 09/05/06 to maintain the adjusted value of positive pressure. It can be programmed with or without pressure support. During the inspiratory phase, there is a decrease of the airway pressure proportional to the demand.
  • Page 18 Review : 04 TECHNICAL AND MAINTENANCE MANUAL Graph VENTILATOR Date: 09/05/06 VT: Regulation of the propelled volume by the ventilator in the mandatory inspiration. Flow Waveform: To change the flow waveform. PSV: Regulates the level of pressure support. Rise Time: To vary the PSV pressurization. Synchronized intermittent ventilation with pressure-controlled mandatory inspiration and spontaneous inspirations with pressure support.
  • Page 19 Review : 04 TECHNICAL AND MAINTENANCE MANUAL Graph VENTILATOR Date: 09/05/06 Airway Pressure Release Ventilation (APRV) It is a mode which ventilates applying periodic switching between two adjustable levels (P-high and P-lower) of continuous positive airway pressure (CPAP) during preset periods of time. Spontaneous breathing is possible without restriction at both levels.
  • Page 20 Review : 04 TECHNICAL AND MAINTENANCE MANUAL Graph VENTILATOR Date: 09/05/06 As the device does not recognize difference between effort reduction and apnea, generically this last term is used. For default the apnea time is established in 15 seconds, but it can be modified at 5, 10, 30 or 60 seconds (Menu key). The backup ventilation for ADULT and PEDIATRIC category is made by volume or pressure mode.
  • Page 21 Review : 04 TECHNICAL AND MAINTENANCE MANUAL Graph VENTILATOR Date: 09/05/06 Alarms and Safety Mechanisms The device has an alarm system with simultaneous messages to alert conditions that, if they persist, they put or they can put in danger the patient's state and could require immediate attention.
