Reliable LTV User manual

Using the LTV Ventilator with a mouthpiece (straw)
For intermittent use to increase the Minute Ventilation (volume and
frequency of air that goes in and out of your lungs).
Settings on the Ventilator will be adjusted by a Respiratory Care
Practitioner, with the input from a physician, to maximize patient
comfort.
The goal is to increase minute ventilation (volume of air going in and
out of the lungs). This is not to be used as a life support device as is set
up in the open circuit system. If the patient needs more support, please
contact his/her physician as soon as possible.
Never use this ventilator or circuit other than the way it was originally
set up by your Respiratory Care Practitioner.
Settings that need to be entered on the front panel:

High pressure Limit
Low Pressure
Extended Features-not available for the user to adjust:
Alarm volume
Alarm Interval-60 seconds to avoid annoyance alarms

alarm

Troubleshooting Alarm Situations
Disc/Sense:
There may be a leak or disconnect in the circuit or proximal pressure
sense line or the proximal pressure sense line is pinched or occluded.
High Pressure:
The circuit pressure may have exceeded the high pressure setting-check
to see if the tubing is crimped. Check the tidal volume setting, this may
have been increased.
Low Pressure:
If the peak inspiratory pressure is below the Low Pressure Alarm
setting-check all connections
When using the LTV with an open circuit (SIP and Puff), we are using
settings to avoid nuisance alarms.
High pressure is set to 50-90 cmh2O, Low pressure is turned off and the
apnea delay is set to 60 sec.
Filters:
On the left side of the ventilator there is a cooling fan with a thin gray
filter over it. At the other end there is a foam filter (off white in color).
Cleaning:
Replace all the supplies listed above once a week or as needed.
Both filters need to be cleaned as needed, checked weekly. Take them
out, clean with warm soapy water, let air dry thoroughly before putting
them back in the machine.
Battery Operation:
The internal battery will be 90% charged within 8 hours when it is
connected to an appropriate power source.

The Charge status LED will be illuminated green when the internal
battery is charged to >90% of its capacity.
The internal battery is to be used for short periods of time.
The internal battery will last for a minimum of 60 minutes on nominal
ventilator settings.
Accessories and Mounting
The LTV ventilator has a backpack available, with or without battery
pack, which can be secured to a power chair or removed and put on a
table top.
The LTV ventilator can be set up to interface with the battery on the
power chair and avoid the use of a separate battery, tray and time. There
is a special adapter that can be ordered through Reliable Medical
Supply.
The LTV ventilator can be secured to a power chair with a specially
ordered vent tray and mounted onto the chair by a mobility specialist.
This will require a prescription from a physician. A mobility specialist
will need to see the power chair and take measurements. This may take
time to get approved by the insurance company.
Follow-Up
The Respiratory Care Practitioner will come out quarterly, or as ordered
by the physician, to check the ventilator and to adjust settings.
