Evaluation: Zoll Z Vent Transport Ventilator, Evaluated for Intrahospital Use

October 17, 2023 | Evaluations & Guidance


  • The Zoll Z Vent is a full-featured portable ventilator designed to provide automated ventilatory support to patients during interhospital or intrahospital transport and in emergency situations.
  • The ventilator is indicated for use in the management of infant through adult patients weighing 5 kg (11 lb) or more with acute or chronic respiratory failure or during resuscitation by providing continuous positive-pressure ventilation.
  • Operating principles:
    • The ventilator includes an oxygen valve and a radial compressor to provide the appropriate gas mixture for the patient.
    • The system includes transducers for pressure measurements, including oxygen input supply and barometric pressure.
    • The wye circuit is part of the ventilator's pneumatic system. The inspiratory side of the wye circuit provides gas to the patient. The expiratory side exhausts directly to atmosphere without returning to the ventilator.
    • The ventilator pneumatically controls the exhalation valve, and a transducer within the ventilator measures the airway pressure.
  • Major features and components:
    • The ventilator is appropriate for use in severe environments where it may be exposed to rain, dust, rough handling, and extremes in temperature and humidity.
      • Operating temperature range: -26°C to 55°C (-15°F to 131°F)
      • Altitude compensation from -85.8 to 7,620 m (-2,250 to 25,000 ft)
    • With an appropriate third-party filter in place, the ventilator can be operated in environments where chemical and/or biological toxins are present.
    • The version of the Zoll Z Vent marked with an MR-conditional label is suitable for use in an MRI environment, with appropriate precautions.
    • It offers multiple modes of ventilation for use with acute or chronic respiratory failure in both intubated and non-intubated patients.
    • A pulse oximeter is integrated into the ventilator.
    • The ventilator provides messages to guide the user through onscreen commands when responding to alarms.
    • The rechargeable battery provides over 10 hours of operation with the pulse oximeter operating.
    • The ventilator is able to operate with or without an external oxygen source.
    • Its design allows operation with both high- and low-pressure oxygen sources. With an appropriate oxygen supply, the ventilator can provide fraction of inspired oxygen (FiO2) values ranging from 21% to 100%.
  • Physical characteristics:
    • Dimensions (H × W × D): 20.3 × 31.8 × 11.4 cm (8.0 × 12.5 × 4.5 in)
    • Weight: 4.4 kg (9.7 lb)
  • The product is typically used in the following hospital environments: critical...
