    Breath Types and Therapy Modes Breath Types Breaths can be initiated (started) and cycled (ended) by either VOCSN or the patient. Depending on the Ventilation Mode and breath control settings chosen, VOCSN may provide the patient with mandatory, assist, or spontaneous breaths.

  • Page 52: Pressure Breaths

    NOTE: The maximum pressure delivered is limited to the High Pressure alarm setting minus 5 cmH2O. VOCSN will deliver flow during the set Inspiratory Time to reach and maintain the set Pressure Control limit. Adjusting the Rise Time control will modify the rate of flow and rate of pressure elevation.

  • Page 53: Volume Breaths

    Breath Types and Therapy Modes Volume Breaths Mandatory and assist breaths are delivered as volume breaths in volume ventilation modes. Volume breaths deliver the set Tidal Volume over the set Inspiratory Time. Airway pressure is a function of patient lung resistance and compliance. NOTE: Delivery of volume breaths to patients with extremely high airway resistance (e.g., 200 cmH2O/L/s) and lung compliance requires high circuit pressure, which may cause the High Pressure alarm to activate before the target tidal volume is reached.

    Control-Volume, SIMV-Pressure, SIMV-Volume, Vol. Targeted-PS, Vol. Targeted-PC, and Vol. Targeted-SIMV. A breath period is the window of time used by VOCSN to determine when mandatory breaths will be delivered to the patient. A breath period is 60 seconds divided by the set Breath Rate. Breath periods begin at the start of a breath, whether patient-triggered or mandatory.

  • Page 55: Assist/Control-Pressure With An Active, Passive, Or Valveless Ventec One-Circuit

    Patient effort will trigger an assist pressure breath. If no patient effort is detected within a breath period, VOCSN will provide a mandatory pressure breath. Both mandatory and assist breaths are delivered at the set Pressure Control (above PEEP) over the set Inspiratory Time.

  • Page 56: Simv-Pressure Mode

    Mandatory CPAP Function VOCSN does not include a separate mode setting for CPAP. The CPAP function is achieved by setting the ventilator to SIMV-Pressure (or SIMV-Volume) mode, and setting the Breath Rate and Pressure Support to zero. All breaths are spontaneous, and are delivered at the set PEEP level.

    90% oxygen at the beginning of the inspiratory phase of each breath. This allows the internal O2 Concentrator in VOCSN (or a high-pressure oxygen source) to deliver the targeted oxygen therapy while using less oxygen than traditional delivery methods.

  • Page 215: Touch Button Cough Therapy And The Ventec Humidifier Bypass

    Because of the high flows generated by VOCSN during Cough exsufflation, water may splash into VOCSN and damage internal components if the humidifier is connected to the Ventec One-Circuit and the Ventec Humidifier Bypass is not used.

  • Page 216: Nebulization

    Technical Description Nebulization VOCSN can be used to drive a 6 L/min nebulizer cup (+N configurations only), or compensate for the added flow to the patient circuit from an external nebulizer. Internal Nebulizer Therapy When activated, the VOCSN nebulization drive produces a constant pressure of 12 PSIG. When connected to most nebulizer cups, this produces a flow of approximately 6 L/min.

  • Page 217: Vocsn Measurements

    VOCSN calculates the airway pressure at the patient interface (mask, tracheal tube, or mouthpiece). To ensure the set PEEP is maintained when an active circuit is used, the VOCSN leak compensation algorithm detects and compensates for any leaks in the Ventec One-Circuit. Pressure on the back side of the valve allows the active exhalation valve to open when the PEEP setting is reached, ensuring that the set PEEP is not exceeded.

    The following graphs illustrate the expected FiO2 based on the patient minute volume when using the FiO2 control to bleed a low-pressure external oxygen source through VOCSN and into an active Ventec One-Circuit. NOTE: Increasing the Flow Trigger control setting requires additional oxygen (in L/min) to achieve the target FiO2. In addition, any leaks in the Ventec One-Circuit will require a higher flow of oxygen input to achieve the target FiO2.
