  • Page 15: Safety Information

    Definitions 1 Safety Information Definitions This manual uses three indicators to highlight critical information: Warning, Caution, and Note. They are defined as follows: WARNING Indicates a condition that can endanger the patient or the ventilator operator. Caution Indicates a condition that can damage the equipment. Note: Indicates points of particular emphasis, that make operation of the ventilator more efficient or convenient.
  • Page 16 If the ventilator fails the alarm tests or if you cannot complete the tests, refer to section 3, “Alarms and Troubleshooting” or call your equipment supplier or Covidien. • The default setting for altitude compensation is YES. Altitude compensation should always be set to YES for accurate volume delivery calculations at all elevations.
  • Page 17 The use of any accessory other than those specified, with the exception of the power supplies or cables sold by Covidien, may lead to an increase in electromagnetic emissions or a decrease in the equipment protection against electromagnetic emissions. If the ventilator is used adjacent to such accessories or stacked with such devices, the ventilator’s performance should be monitored to verify normal...
  • Page 18 Safety Information • When changing the mode during ventilation, significant transitions of pressure, flow or cycling rate might occur, depending on the difference between the modes. Before setting the new mode, first ensure that the settings between the different modes are compatible. This reduces the risk of discomfort and harm to the patient.
  • Page 19 Warnings • When an alarm condition is triggered, or there is evidence of a patient-ventilator fault or problem, examine the patient first before examining the ventilator. • Adjustable alarms should not be systematically cancelled; instead, they should be adjusted according to the needs and condition of the patient.

  • Page 20: Safety Information

    Safety Information Warnings regarding Electrical Power • To ensure that ventilation continues uninterrupted, ensure alternative power sources are available (AC power source, extra batteries, or an auxiliary DC car adapter). Be prepared for the possibility of power failure by having an alternative means of ventilation ready for use. •...
  • Page 21 • If using oxygen with the Puritan Bennett™ 520 Ventilator, Covidien recommends using an oxygen analyser with minimum and maximum concentration alarms. Always measure the delivered oxygen with a calibrated oxygen analyser that features a minimum and maximum concentration alarm in order to ensure that the prescribed oxygen concentration is delivered to the patient.
  • Page 22 Safety Information • To ensure stability, when the Puritan Bennett™ 520 Ventilator is mounted on a cart, the weight of the oxygen bottle should not exceed 14 kg (30 lbs). • The oxygen supply hose ages even when it is not in use and should be replaced periodically. The expiration date may be located on the back of the hose end-piece.

  • Page 129: F Glossary

    F Glossary AC Power Alternating current. Alarm Pause The audible and visual alarms cease and the symbol appears. The symbol will remain until the cause of the alarm is addressed. For example, when the ventilator is running on internal battery, the AC Disconnection alarm may be paused, and the alarm paused symbol will appear until the device is plugged into AC.
  • Page 130 Glossary Bias flow Turbine flow during exhalation phase through the patient circuit to avoid rebreathing. An abbreviation for “breaths per minute, ” which is the unit of measure for breath rate (see below). Breath Rate (Back Up R) The total number of breaths, both machine and spontaneous, delivered by a ventilator in one minute. Caregiver An individual who assists a patient with the tasks of daily living.
  • Page 131 Inspiratory Sensitivity (I Sens) Level of inspiratory effort the patient has to provide during the initiation of a machine breath. The sensitivity levels (from 1P to 5) correspond to differences in flow compared to the bias flow. Level 1P is the most sensitive (for a pediatric use) and requires the least effort to trigger a breath.
  • Page 132 Glossary Mbar An abbreviation for “millibar“ which is a unit of measure for atmospheric pressure. Mean Airway Pressure Average patient pressure during each breath. Minimum Exhalation Time Minimum exhalation time before allowing the patient inspiratory trigger. Minimum Inspiratory Time Minimum inspiratory time before allowing the patient to exhale. M Vol (Minute Volume) Flow delivered at each breath to the patient is measured by the inspiratory flow sensor and that measurement is used to calculate minute volume (Vt x Rtot)
  • Page 133 Pressure Support (P Support) Augmentation of the patient’s ventilation synchronously with inspiratory effort until a preset pressure is met. Pressure is maintained until inspiratory flow is reduced to a percentage of peak flow that depends on the exhalation sensitivity setting for the inspiration, when the ventilator cycles into exhalation.
  • Page 134 Glossary Vent Time (Ventilation Time) The ventilation duration data is based on the patient counter and shows the total ventilation time in hours and minutes over the previous 24 hour period. Vt Target (Target volume) The Vt Target feature enables the ventilator to reach a set volume of gas to be delivered to the patient using a range of pressures in the pressure-based ventilation modes.
