Warnings, Cautions, and Notes
• If the EXP HOLD key is held continuously, and the expiratory hold
maneuver exceeds 5 seconds, the ventilator automatically
terminates the expiratory hold maneuver and begins a new
inspiratory period.
• If Auto PEEP as calculated in Equation 1: Auto-PEEP = Expiratory
Pause Pressure – End Expiratory Pressure, is negative, Auto-PEEP
will be displayed as “—.”
• All components of the patient circuit must not have leaks in order
to pass SST.
• If time is found to be incorrect more than once in the
preoperational procedure, an internal battery may have to be
replaced. Contact qualified service personnel or call Respironics
Customer Service at 1-800-345-6443.
• Because conditions and practices in health care institutions vary,
this manual can only describe general guidelines. It is the user’s
responsibility to ensure the validity and effectiveness of the
methods used.
• Because some environments cause a quicker collection of lint and
dust than others, inspect and clean the fan filters more often than
every 250 hours if necessary.
• The “Hardware” function and EST in the Diagnostics Mode should
only be run by qualified personnel.
• A “restart” is an infrequent event.
• The gas return port on the ventilator is a cylindrical port which
requires mating to a specified expiratory filter to seal the
expiratory limb.
• The humidifier power connection is available only on 100-120VAC
ventilators.
• Record O
2
sensor manufacturing or warranty numbers and
installation date for future reference. Save manufacturers
instruction about end of life replacement.
• To ensure accurate O
2
monitoring, check O
2
sensors periodically
and replace as per manufacturer specification.
• Sensor performance and expected operating life information is
outlined in the sensor manufacturer’s instructions for use.
Thoroughly review all O
2
sensor instructions prior to installation
and use with the Respironics V200 Ventilator.
• O
2
sensor calibration is performed during EST. If recalibration of
the O
2
sensor is required, follow the instructions in “Extended
Self Test (EST)” on page 11-4 for running EST.
