2.3.5
Battery Fully Charged
When LifeStyle is connected to an AC or DC outlet and is in the
yellow
light illuminates and displays continuously to indicate that the
BATTERY
battery is fully charged. However, when charging the battery for the first time, the
battery should be left in the charger for 12 hours even if the yellow
is on continuously.
2.3.6
Cannula Disconnect
When LifeStyle is connected to a power source and does not sense breathing within
a predetermined time period, a constant alarm sounds, and the red
illuminates. If this occurs, the patient is instructed to check the connection from the
cannula to the LifeStyle unit, make sure that the nasal cannula is positioned properly
on the face, and ensure that breathing is through the nose. If the alarm continues to
sound, the patient should change to an alternate source of oxygen and contact the
Equipment Provider.
2.3.7
Performance Warning
The performance of LifeStyle can be affected by two conditions. The first is if the
user's breathing rate causes the LifeStyle unit's capacity to be exceeded. The
LifeStyle unit supplies a fixed amount of high-concentration oxygen. The amount of
oxygen that LifeStyle supplies is dependent on the flow control switch setting and
the breathing rate. If the breathing rate is too fast for the flow selector setting, the
capacity of LifeStyle can be exceeded.
The second condition that can result in decreased performance is a general
malfunction. LifeStyle monitors its performance and alerts the patient if this occurs.
If either of these events occurs, a half-second alarm sounds every five seconds. If
breathing is too fast for the flow selector setting and LifeStyle capacity is exceeded,
the red
light flashes. If a general malfunction occurs, a steady red
ALARM
light appears. During this time, LifeStyle is still producing high-purity
ALARM
oxygen and may continue to be used. The patient should reduce activity or consider
locating another source of oxygen.
2.3.8
LifeStyle Capacity Exceeded
When the breathing rate has caused the capacity of LifeStyle to be exceeded, a
half-second alarm sounds every half second, and the red alarm light flashes. When
this occurs, oxygen concentration is outside specifications. The patient should
change to another source of oxygen and contact the Equipment Provider.
