The CPAP (Continuous Positive Airway Pressure) titration is a test that is
performed at the St. Rita's Sleep Disorders Lab once obstructive sleep apnea
has been determined by an OSA or Split Night study. During this study, patients
are fitted with a mask that is attached to a breathing machine. The patient
is then instructed to breathe as normal as possible while varying levels of
pressure/airflow are used to determine the level at which the patient's snoring,
apnea events, and/or arousals are eliminated.
Patients are first seen in our Sleep Disorders Clinic, by one of our physicians
who are fellows of the American Sleep Disorders Association. Either a Split
Night study is ordered or the patient is seen for a full night OSA following
which the sleep specialist orders the CPAP trial.
Before the study, sleep technicians apply a number of electrodes on the head
and skin to record various activities (brain wave, muscle movements, eye movements,
breathing through the mouth and nose, snoring, heart rate and leg movements).
Flexible elastic belts are placed around the chest and abdomen to measure breathing.
A pulse oximeter is typically clipped to the index finger as well. In addition,
the patient is fitted with a mask so that the titration can be done. All of these areas are monitored during the study.
Typically, the study is videotaped so that it can be observed, if need be,
during the staging and scoring of the study. Once the study is completed, a
follow-up appointment is scheduled at the clinic to discuss and review the
study and all appropriate recommendations.
Throughout the process, the referring physician is sent all reports with recommendations.
Normally, patients that will be given the CPAP Titration test are pediatric
(three plus years of age) through the geriatric population who might be suspected
of having sleep apnea. For the pediatric patient (three years through 15 years
of age), a parent of guardian is required to stay on the St. Rita's campus
throughout the night. Arrangements can be made in advance to stay in one of
the nearby examination rooms. Unless the child is very young, parents/guardians
are discouraged from staying in the same room/bed as the child. For all others,
every attempt will be made to meet any special needs any patients might have.
On the day of the study, caffeine (coffee, tea, cola, and chocolate) should
be avoided after 2:00 p.m. All medications should be taken as usual. Before
coming in for the study, hair should be washed and dried, however no hair products
(hair spray, gels or oils) should be used. It is suggested that the patient
pack an overnight bag for his/her convenience. In addition, patients are permitted
to bring their own pillow if they feel it will help them to sleep better.
