Airway Apnea Detection the the Respironics System One.. An apnea is

detected when there is an 80% reduction in airflow from a baseline

for at least 10 seconds if there is no airflow detected for 10

|
occurred while the patient has a clear airway or an obstructed

respiration is an abnormal pattern of breathing characterized by
|
|
|
|
|
|
progressively deeper and sometimes faster breathing, followed by a
|
|
|
|
|
|
gradual decrease that results in a temporary stop in breathing called
|
|
|
|
|
|
an apnea. The pattern repeats, with each cycle usually taking 30
|
|
|
|
|
|
seconds to 2 minutes. It is an oscillation of ventilation between
|
|
|
|
|
|
apnea and hyperpnea with a crescendo-diminuendo pattern, and is
|
|
|
|
|
|
associated with changing serum partial pressures of oxygen and carbon

respiration and periodic breathing are the two regions on a spectrum
|
|
|
|
|
|
of severity of oscillatory tidal volume. The distinction lies in what
|
|
|
|
|
|
we observe happening at the trough of ventilation: if there is apnea,
|
|
|
|
|
|
we describe it as Cheyne-Stokes respiration (since apnea is a
|
|
|
|
|
|
prominent feature in their original description); if there is only
|
|
|
|
|
|
hypopnea (abnormally small but not absent breaths) then we call it
|
|
|
|
|
|
periodic breathing. Physiologically and mathematically, the phenomena
|
|
|
|
|
|
are less different than they appear, because breaths that are smaller
|
|
|
|
|
|
than the anatomical dead space do not actually ventilate the lung and
|
|
|
|
|
|
so - from the point of view of gas concentrations in an alveolus -
|
|
|
|
|
|
the nadir of hypopnea in periodic breathing may be indistinguishable
|

from apnea.</font></font></font></p>
