1.2 Warnings
General Precautions For Use
WARNING
•
Federal law restricts this device to sale by or on the order of a licensed physician.
•
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” .
•
Be aware this manual describes how to respond to ventilator alarms, 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. This is particularly true for ventilator-dependent patients.
Supplementary observation, appropriate for the patient's condition, is also recommended.
•
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—particularly for ventilator-
dependent patients.
•
.Do not allow a patient to remain connected to the ventilator when ventilation is stopped, because a
substantial quantity of expiratory gas, primarily carbon dioxide, may be inhaled by the patient. In
some circumstances, inhaling carbon dioxide may lead to under-ventilation, suffocation, and serious
injury or death.
•
The ventilator must not be used with flammable anesthetic substances.
•
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.
•
You must start the ventilator and allow it to complete one full breath cycle prior to connecting the
patient. Do not connect the patient before this cycle completes.
•
.Due to its limited internal battery’s reserve capacity, the ventilator should only be operated
occasionally while powered by its internal battery. Ensure that the internal battery never becomes fully
discharged.
•
A ventilator-dependent patient 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 alarmed condition or experiences a problem.
•
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.
•
Verify the functionality of the alarms conditions before connecting the patient to the ventilator.
•
If the ventilator fails the alarm tests or if you cannot complete the tests, refer to
chapter
3, “Alarms and Troubleshooting” or call your equipment supplier or Puritan Bennett.
•
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, the ventilation will resume
without having to press the VENTILATION ON/OFF button.
•
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. The use of a bacterial filter at the ventilator’s outlet—or both ports if a
double-limb circuit is used—is recommended. Refer to chapter
7, “Cleaning” .
•
Handle the ventilator with care during and after use, particularly when room temperatures are high.
Some ventilator surfaces may become hot, even if safety specifications are not exceeded.
