Definitions

1 Safety Information 1.1

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. It is essential to read, understand and follow these instructions before using the Puritan Bennett™ 520 Ventilator. In order to use the ventilator correctly and efficiently and to help prevent incidents, please pay particular attention to section 1.2, “Warnings” , as well as all warnings and cautions contained throughout this manual.

1.2

Warnings Fire Hazard Warnings

• The ventilator must not be used with flammable anesthetic substances. • To reduce the risk of a fire hazard, keep matches, lighted cigarettes, and all other sources of ignition (such as flammable anesthetics and/or heaters) away from the ventilator and oxygen hoses.

• Never expose any batteries to direct flame. • In the event of an oxygen leak, shut down the supply of oxygen at its source. In addition, remove and/or keep any incandescent source away from the device, which may be enriched with oxygen. Circulate fresh air into the room to reduce the oxygen concentration level.

Warnings about Reducing Infection

• To reduce the risk of infection, wash your hands thoroughly before and after handling the ventilator or its accessories.

• A patient treated by mechanical ventilation is highly vulnerable to the risks of infection. Dirty or contaminated equipment is a potential source of infection. Clean the ventilator and its accessories regularly and systematically before and after each use and following any maintenance procedure to reduce the risks of infection.

• Single Use accessories should not be reused. • The air inlet filter is for use on a single patient and is not reusable; do not attempt to wash, clean, or reuse it.

Clinician’s Manual

Safety Information

Warnings before Using Equipment

• The ventilator must be used only under the responsibility and on the prescription of a doctor. • The ventilator is not intended to be used for patients without breathing autonomy or who are ventilator dependent.

• The ventilator must be used according to its intended use. Refer to 2.1, “Indications for Use”. • Do not start ventilation until you ensure that the device is suitably assembled, that the air inlet filter is properly installed and is not obstructed, and that there is proper clearance all around the unit. Also ensure that the patient circuit is suitably connected to both the ventilator and the patient and that the patient circuit, including all hoses, is not damaged or obstructed.

• Before dispensing the ventilator to caregivers or the patient for home use, ensure the Locking Key is activated so that critical ventilator settings are not modified.

• Do not perform ventilator alarm tests while the patient is connected to the ventilator. Provide the patient with an alternate means of ventilation before conducting these tests.

• Verify the functionality of the alarm conditions before connecting the patient to the ventilator. Refer to Appendix F, “Alarms Tests”.

• If the ventilator fails the alarm tests or if you cannot complete the tests, refer to section 5.8, “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.

• Before starting ventilation, ensure that the device is properly assembled and that the air inlet, cooling vents, and alarm sound diffusion holes are not obstructed. Ensure also that the patient circuit is of the proper configuration, properly connected to the ventilator, and that the circuit hoses are neither damaged nor compressed and contain no obstructions or foreign bodies.

• This ventilator offers a choice of breath delivery modes and types. Throughout the patient’s treatment, the clinician should carefully select the ventilation mode and/or breath type to use for that patient. This selection should be based on the clinician’s clinical judgment, considering the condition and needs of the individual patient, as such condition and needs change from time to time, and considering the benefits, limitations and operating characteristics of each mode and/or breath type.

• Patients on home care ventilation equipment should be appropriately monitored by clinicians, caregivers and suitable monitoring equipment, as advised by the patient’s clinician. The Puritan Bennett™ 520 Ventilator is not intended to be a comprehensive monitoring device and does not activate alarms for all types of dangerous conditions for patients.

Warnings regarding Environment of Use

• Do not operate the ventilator in direct sunlight, near heat sources, outdoors, or near installations where liquid may pose a risk without first providing adequate protection for the device.

• Avoid using the ventilator, if possible, in dusty environments. Dusty environments may require more vigilant monitoring, cleaning, and/or replacement of air intake and other filters.

• Ensure that the ventilator’s immediate surroundings allow for the proper operational connection of the device without folding, pinching, or damaging any of the required cables or tubes, and that the connection of the patient circuit to the patient provides for a secure, comfortable fit.

• Place the ventilator in a safe place when ventilating and according to the recommendations in this manual.

• Do not place the ventilator in a position where a child can reach it or in any position that might cause it to fall on the patient or someone else.

• To ensure correct and lasting operation of the ventilator, ensure that its air circulation holes (main inlet or cooling) are never obstructed. Place the device in an area where air can freely circulate around the ventilator and avoid installing it near floating fabrics, such as curtains.

Warnings

• If the ventilator has been transported or stored at a temperature that differs more than 20 °C ( 36 °F) from the temperature in which it will be operating, the ventilator should be allowed to stabilise in its operating environment for at least two (2) hours prior to use.

• If the ambient temperature where the device is operated is greater than 35 °C (95 °F), the flow supplied at the device outlet may exceed 41 °C (106 °F). This may lead to undesirable side effects for the patient. To avoid injury to the patient move the patient and the ventilator to a cooler location.

• The default setting for altitude compensation is YES. Altitude compensation should always be set to YES for accurate volume delivery calculations at all elevations.

• To reduce the risk of a fire hazard, keep matches, lighted cigarettes, and all other sources of ignition (such as flammable anesthetics and/or heaters) away from the ventilator and oxygen hoses.

• Before starting ventilation, ensure that the device is properly assembled and that the air inlet, cooling vents, and alarm sound diffusion holes are not obstructed. Ensure also that the patient circuit is of the proper configuration, properly connected to the ventilator, and that the circuit hoses are neither damaged nor compressed and contain no obstructions or foreign bodies.

• Regularly check the cleanliness of the air inlet filter located on the rear of the ventilator. If necessary, replace the filter before the recommended replacement period is over (see chapter 10, “Routine Maintenance”). This is particularly important when the ventilator is installed on a wheelchair, because environmental conditions may cause the filter to become dirty more rapidly.

• Due to typical voltage fluctuations that occur during normal power wheelchair use, the wheelchair mains battery should never be used to power the Puritan Bennett™ 520 Ventilator. The ventilator should always be connected to an independent power source (e.g. AC power, extra batteries, or DC power source).

• Handle the ventilator with care during and after use, particularly when ambient temperatures are high. Some ventilator surfaces may become hot, even if safety specifications are not exceeded.

• Alarm volume should be adjusted with respect to the ventilator’s operating environment and so that the patient's caretakers can hear the alarms. See 7.3.4, “Alarm Volume”. The audible alarm vents located at the front of the device should never be obstructed.

Warnings Regarding Electromagnetic Interference

• The Puritan Bennett™ 520 ventilator requires special precautions for electromagnetic compatibility and should be installed and started according to the recommendations found in Appendix B, “Specifications.” In particular, the use of nearby mobile and portable communications equipment using radio frequencies, such as mobile telephones or other systems exceeding the levels set in the IEC 60601-1-2 standard, may affect its operation. Refer to section B.10, “Manufacturer’s Declaration”.

• 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 operation.

Warnings regarding Settings

• Before starting ventilation, always verify that all settings are properly set in accordance with the required prescription.

• The Puritan Bennett™ 520 Ventilator offers a variety of breath delivery modes. Throughout the patient’s treatment, the clinician should carefully select the ventilation mode or modes to use for that patient. This selection should be based on the clinician's clinical judgment, considering the condition and needs of the individual patient, as such condition and needs change from time to time, and considering the benefits, limitations and operating characteristics of each mode.

• The CPAP mode does not provide a set respiratory rate. Do not use this mode if it is not appropriate for the patient’s condition.

Safety Information

• Alarm volume should be adjusted with respect to the ventilator’s operating environment and so that the patient's caretakers can hear the alarms. See 7.3.4, “Alarm Volume”.

• Ensure that the I Sens setting is not set to OFF when ventilating patients capable of triggering spontaneous breaths.

• Monitor the patient's state of health in order to ensure that the ventilator’s settings are always suited to the patient’s current physiological requirements.

• In adult or pediatric use ensure that the adjusted tidal volume is compatible with the needs of the patient.

• 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.

• The setting of the Min PIP alarm must be adjusted for the patient, but must also be set high enough to allow the PATIENT DISCONNECTION alarm to trigger properly. Perform the Low Pressure Test (refer to section F.1, “Low Pressure Test”) to ensure the Min PIP alarm is properly set.

• If APNEA TIME is set to a value higher than 60/Control R then the APNEA alarm will not activate. • The Apnea Alarm should be set to YES if an audible alarm sound is desired when apnea events occur. • Setting Alarm limits to extreme values can cause the ventilator alarms to malfunction. • Ensure the I Time setting is compatible with the physiological requirements of the patient. • Adjustable alarms should not be systematically cancelled; instead, they should be adjusted according to the needs and condition of the patient.

• The inspiration trigger threshold should be carefully modified in order to avoid the risk of false triggering or “autotriggering” of the ventilator. For example, Level 1P, the most sensitive mode, is recommended for pediatric use. However, for an adult, this setting may result in autotriggering.

Warnings Applicable during Use of Equipment

• The ventilator must be used only under the responsibility and on the prescription of a doctor. • The ventilator must be used according to its intended use. Refer to section 2.1, “Indications for Use”. • The ventilator is not intended to be used for patients without breathing autonomy or who are ventilator dependent.

• Be aware this manual describes how to respond to the ventilator, but it does NOT tell you how to respond to the patient.

• While the ventilator is in use, an alternative means of ventilation should always be available in the event of a ventilator problem. Supplementary observation, appropriate for the patient's condition, is also recommended.

• Patients should always be monitored by trained and competent medical personnel. Ensure that the patient’s caregiver is able and prepared to take suitable action in the event the ventilator identifies an alarm condition or experiences a problem.

• 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.

• A continuous alarm condition will be activated if the ventilator power switch is turned off while ventilation is in progress. When the power switch is turned back on again, ventilation will resume without having to press the VENTILATION ON/OFF button.

• If the device is damaged, its external housing is not correctly closed, or it behaves in a way that is not described in this manual (excessive noise, heat emission, unusual odour, alarms not triggered during the start-up procedure), the oxygen and power supplies should be disconnected and use of the device stopped immediately.
