Efficacy of Automated Continuous Positive Airway Pressure in Children
With Sleep-Related Breathing Disorders in an Attended Setting

ABSTRACT. Introduction. The purpose of this study
was to evaluate the safety and efficacy of automated con-
tinuous positive airway pressure (Auto-CPAP) in children.
Sleep-related breathing disorders (SRBDs) include the
clinical spectrum of symptomatic chronic snoring, upper
airway resistance syndrome, and obstructive sleep apnea.
This spectrum occurs in adults and children. Less data
are available for children despite recognition of the con-
dition’s prevalence. CPAP has been an established treat-
ment for adults and children. Treatment with Auto-CPAP
has been available for adults but has not been reported
previously in children.
Methods. A group of 14 children (8 months to 12 years
old) was evaluated prospectively with baseline polysom-
nographic study and CPAP titration performed with Au-
to-CPAP under sleep technologist supervision.
Results. The results demonstrated that Auto-CPAP is
sensitive and effective for children with obstructive
sleep apnea in an attended setting. There was 1 subject
who did not seem to tolerate Auto-CPAP, but when she
was switched to conventional CPAP, she did not tolerate
that either. In this subject, the mask never fit well. She
was excluded from the analysis. All other patients had a
decrease in the number of abnormal breathing events
during sleep. The respiratory disturbance index de-
creased from a mean of 12.6 (SD: 12.4) to 2.6 (SD: 2.7)
events per hour. The lowest oxygen saturation improved
from a mean of 86% (SD: 10.8) to 93.6% (SD: 3.9).
Conclusions. We conclude that Auto-CPAP is safe
and effective in an attended environment. Auto-CPAP
did not eliminate all the abnormal respiratory events. In
subjects 1 and 14, the final respiratory index improved
but remained >5 events per hour (5.9 and 7.7, respec-
tively). We suspect that this was because of problems
with the masks leaking, which illustrates the importance
of follow-up and possible need for retitration in some
patients. Proper mask fit is essential for successful treat-
ment. Additional work is needed to evaluate its utility in
the home setting. This study was designed to evaluate
Auto-CPAP titration in an attended environment. It did
not indicate information about the effectiveness in an
unattended or home setting. We demonstrate that Auto-
CPAP is able to detect abnormal breathing events during
sleep in children and may provide the necessary pressure
to correct these events. Auto-CPAP can be used safely for
pressure titration in an attended setting. Auto-CPAP de-
vices from different manufactures are commercially
available for adults. These different devices may have
different algorithms and sensitivities to detect abnormal
breathing episodes. This study was performed with only
1 specific model of Auto-CPAP. Our results should not
be extrapolated to other Auto-CPAP devices without em-
pirical confirmation of the devices’ ability to detect and
correct events in children. Auto-CPAP can be an alterna-
tive treatment for SRBDS in the pediatric population.
These results allow for speculation of possible applica-
tions for Auto-CPAP in children. A potential advantage
of Auto-CPAP includes permitting the initiation of treat-
ment while awaiting a standard CPAP titration. The vari-
able pressure response of Auto-CPAP allows for treat-
ment under different situations such as upper airway
infections, different sleeping positions, and changes in
weight. As the child grows, the amount of positive pres-
sure needed to maintain airway patency may change.
Auto-CPAP may be able to adjust to these changing
pressure requirements. Auto-CPAP does not eliminate
the need for periodic office visits and evaluations of
the clinical course. Pediatrics 2004;113:e412–e417. URL:

n children, sleep-related breathing disorders
(SRBDs) are estimated to occur in 2% to 6% of
the population.

Consequences of SRBDs in children include car-
diovascular complications.
2–5
In addition to the car-
diovascular consequences, behavioral changes have
been associated with SRBDs and may include irrita-
bility, aggressiveness, hyperactivity, and disciplinary
problems. Several studies have demonstrated a high
incidence of impaired school performance, hyperac-
tivity, decreased intellectual performance, and emo-
tional problems associated with SRBDs in children.
6–9
SRBD symptoms were associated with attention-def-
icit/hyperactivity disorder in a cross-sectional study
involving 866 children.

Treatment options for children with SRBDs typi-
cally are surgery and continuous positive airway
pressure (CPAP). Oral appliances are available for
adults but are not routinely used in children. Surgery
(adenotonsillectomy) is the most common form of
treatment in children. The cure rate with surgery is
unknown, but improvement of the condition has
been reported at 85% by Suen et al.

In the presence
of craniofacial or neurologic problems, the effective-
ness of surgery may be lower.
