VOCSN integrates five separate devices including a ventilator, oxygen concentrator, cough assist, suction, and nebulizer, into one unified respiratory system for hospital, institutional, transport, and home environments. VOCSN is controlled with an intuitive touchscreen operating system to deliver treatments in seconds instead of minutes.

The VOCSN critical care ventilator provides invasive, noninvasive, and mouthpiece ventilation. Designed to work in hospital, institutional, transport, and home environments, VOCSN delivers a comprehensive set of ventilation modes and settings to meet patient’s needs. The advanced unified respiratory system combines responsive leak and circuit compensation as well as precision flow trigger controls to enable comfortable breathing and accurate therapy.

Highlighted Technology

  • Ready for Hospital, Transport, and Home
    Using a customized radial blower and advanced software, VOCSN meets the rigorous ISO 80601-2-12 international standard for critical-care ventilators.
  • Advanced Leak Compensation
    VOCSN automatically compensates for high flows and large leaks up to 75 L/min at 20 cmH2O. This reduces nuisance alarms and allows the use of more comfortable noninvasive masks.
  • Integrated Oxygen Blending and Monitoring
    VOCSN includes an internal oxygen concentrator as well as inlets for low and high pressure oxygen sources. An onboard FiO2 monitor displays and tracks oxygen delivery. If external oxygen becomes disconnected, VOCSN activates an alarm and allows you to easily switch to the internal concentrator, providing an emergency backup source of oxygen.
  • Circuit Compensation
    Typically only found in critical care ventilators, circuit compensation helps overcome lost volume in the patient circuit. This technology improves airflow delivery accuracy during volume ventilation, which is especially important for pediatric patients.
  • Therapy Tracker
    The integrated Therapy Tracker records alarms and all changes to settings to the ventilator as well as all ancillary therapies.
Ventilation, Active Circuit Side


VOCSN can deliver the equivalent of 6 L/min of oxygen using the onboard internal oxygen concentrator.

The Oxygen Direct™ system uses an independent oxygen tube inside the circuit. This enables oxygen to be delivered directly to the patient in pulse-dose mode during the beginning part of the breath, precisely when the patient needs oxygen most.

The oxygen system is up to three times more efficient than stationary concentrators. This significantly decreases the size of the oxygen concentrator and maximizes battery life. Most importantly, it makes traveling and using oxygen easier.

Highlighted Technology

  • Internal Oxygen Concentrator
    The internal oxygen concentrator produces the equivalent of up to 6 L/min or up to 40 percent oxygen in adult patients. The redesigned pressure swing adsorption process and Oxygen Direct™ system mean more oxygen is generated using less battery power.
  • Onboard FiO2 Monitor
    The VOCSN onboard FiO2 monitor verifies accurate oxygen delivery.
  • External Oxygen Sources 
    VOCSN may include low pressure and high pressure ports for external oxygen. If external oxygen becomes disconnected, VOCSN activates an alarm and allows you to switch to the internal concentrator, providing an emergency backup source of oxygen.


By unifying ventilation, cough, and suction into one system, it now takes seconds instead of minutes to administer cough therapy with Touch Button Cough™. The Ventec One-Circuit™ features a patent pending high flow valve design, allowing patients to use the same circuit for ventilation and cough. Using the Cough + Suction feature, the suction is activated during the cough therapy to clear secretions. Patients using invasive ventilation can use the Secretion Trap™ to easily clear secretions from the circuit. Once the set number of cough cycles is complete, ventilation automatically resumes.

Touch Button Cough™: The VOCSN cough is activated with the touch of a button to make airway clearance easy. Patients remain connected to the ventilator at all times, and there is no need to disconnect circuits between uses. The system is designed to reduce the gaps in ventilation, decrease the risk of patient misconnection, and minimize exposure to the patient’s airway.

Highlighted Technology

  • Advanced Cough Rise Time
    VOCSN uses an advanced rise time algorithm during cough.  The system is designed to reduce the amount of mucus going back to the patient.
  • Breath Sync
    When Breath Sync is enabled, VOCSN monitors patient breathing and triggers a cough at a natural point in the breathing cycle. The technology allows the patient to transition gently in and out of the cough therapy and seamlessly return to ventilation.


The VOCSN high flow suction provides quiet and effective airway clearance. Working in conjunction with the Secretion Trap, suction can be used to clear secretions from the patient’s airway. VOCSN ensures consistent and precise vacuum pressure to quickly clear mucus. Plus, the suction system uses Ventec’s unique sound muffler, making it more than three times quieter than traditional suction machines.

Highlighted Technology

  • Cough + Suction
    VOCSN activates the suction system during the cough therapy. Caregivers can activate a cough, clear the mucus, and return to ventilation in less than one minute.
  • Suction Travel System
    The 300 mL detachable travel canister allows suction on the go. This size also supports emergency responders and transport.
  • Ventec Secretion Trap
    The suction system removes mucus from the circuit simplifying mucus management.  The system allows invasive patients to remain connected to the same circuit during ventilation, suction


VOCSN provides an integrated nebulizer drive of 6 L/min to make medication delivery seamless.  VOCSN automatically compensates for the airflow from the nebulizer drive to ensure accurate ventilation and comfortable breathing.  Plus, VOCSN records data about each treatment and automatically turns off the nebulizer once the therapy is complete.

Highlighted Technology

  • Nebulizer Noise Muffler
    The system uses Ventec’s unique sound muffler technology and is half the noise of traditional nebulizer systems.
  • Therapy Tracker
    Each use of the nebulizer is recorded in the event log to help ensure medication compliance.
  • Programmable Auto-Off
    The nebulizer can be set to turn off following completed use.
