Periodic Maintenance - Respironics ESPRIT Service Manual

Chapter 4. Periodic Maintenance
REF 580-1000-02 G
Perform cleaning, sterilizing, and periodic maintenance procedures to ensure
consistent ventilator operation. Hospital personnel can perform all
maintenance tasks except the annual and 12,500-hour preventive
maintenance procedures (the preventive maintenance procedures must be
performed by a qualified service technician). The Esprit Ventilator Operator's
Manual summarizes periodic care and maintenance procedures. Table 4-1
shows the periodic maintenance schedule.
Frequency
During ventilator • Inspiratory bacteria filter
setup
• Ventilator and patient circuit
components
• Inspiratory and expiratory filters
At least daily, and as • Inspiratory and expiratory filters
recommended by
filter manufacturers
CAUTION: Do not operate the Esprit Ventilator without a properly functioning
expiratory filter and heater. Doing so may cause damage to delicate ventilator
components, such as the expiratory flow sensor, which may lead to inaccurate
spirometry or a Vent Inop condition.
WARNING: Vent Inop is a serious condition which is indicated by both visual and
audible alarms. If the ventilator is attached to a patient when Vent Inop occurs, the
patient must be supported with another means of life support ventilation.
At least daily • Oxygen supply water trap and
filter

Schedule for Periodic Maintenance
Component Maintenance
• Check filter for occlusions, cracks and
tears.
• Perform SST (Short Self-Test)
whenever circuit components are
changed
• Perform EST (Extended Self-Test)
between patient uses
• Ensure that the ventilator functions
normally with both filters in place
• Monitor performance of filters and
replace as needed. Review ventilator
patient graphics frequently for changes
in expiratory resistance which may
indicate degradation of expiratory filter.
• Follow filter manufacturer
recommendations regarding duration
of use, maintenance (for reusable
filters), removal and disposal. Note
that high humidity and aerosol
medications may reduce expiratory
filter life, increase expiratory
resistance, and/or cause filter damage.
• Check and empty as required every
shift
