Systems’ advanced monitoring technology, "SleepCheck",
was developed as a screening device for those who
may suffer from sleep apnea. This product is
especially designed for monitoring in the comfort of
the patient’s own home. This innovative concept,
which detects all three types of apnea (obstructive,
central and hypopnea), is technologically
sophisticated yet affordable and user-friendly.
SleepCheck not only answers the need for a simple,
at-home screening device, but also has application
for determining the need for further clinical
evaluation by polysomnography (PSG).
At-home testing
requires only that the patient self-apply a
disposable airflow cannula to the upper lip (similar
to an oxygen cannula) and push the start button. The
pager size unit can be clipped to the patient’s bed
clothing or placed next to a pillow. SleepCheck
measures the patients’ respiratory airflow pressure
at the nose and mouth. A unique feature is a LCD bar
graph that follows the breathing pattern. As the
patient inhales and exhales, the bar moves back and
forth, verifying proper cannula application and
monitor operation. When breathing decreases 50% or
more for 10 seconds or longer, this event is
considered an apnea event and tallied on the LCD
readout.
This miniature battery-powered unit is completely
portable, allowing the patient total freedom of
movement while sleeping. SleepCheck is the first
monitor for home use that directly counts and
displays apnea events during sleep. Unlike other
sleep monitoring instruments, which traditionally
require a professional to attach an array of sensors
and electrodes to a bedside recorder, SleepCheck
does not require professional or technical
assistance. The unit features 9 hours of recording
capacity, counts total apnea/hypopnea events,
displays the number of events for each hour, the
average events per hour (AH) for the sleep night and
single button memory recall.
To verify the integrity of the monitoring process,
an error detection function reports the condition of
the cannula sensor during sleep. If the air cannula
becomes displaced from the nose or mouth area or is
unable to sense adequate airflow for at least 15
minutes, an error message ("E") is displayed on the
LCD for each hour of monitoring in which the
condition occurred.
Accuracy of SleepCheck:
Validation studies for SleepCheck have been
presented at 9 professional conferences and 3
articles published in the prestigious Journal
ofSleep. Clinical studies have confirmed a 97%
overall correlation and 94% point to point for
identifying apnea events against PSG evaluations.
