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 seconds. During the apnea, one or more pressure test pulses are delivered by the device. The device evaluates the response of the patient to the test pulse(s) and assesses whether the apnea has occurred while the patient has a clear airway or an obstructed airway. The airway is determined to be clear if the pressure test pulse generates a significant amount of flow; otherwise the airway is determined to be obstructed.</font></font></font></p> <p style="font-variant: normal; letter-spacing: normal; font-style: normal; font-weight: normal; orphans: 2; widows: 2"> <font color="#252525"><font face="sans-serif"><font size="2" style="font-size: 10pt">Apnea Detection guidelines per ResMed machines..Apnea...When the respiratory flow decreases by more than 75% for at least 10 seconds.</font></font></font></p> <h3 class="western" style="margin-top: 0cm; margin-bottom: 0cm; border: none; padding: 0cm; font-variant: normal; letter-spacing: normal; font-style: normal; line-height: 160%; orphans: 2; widows: 2; background: #ffffff"><a name="ASV"></a> <font color="#000000"><font face="sans-serif"><b>ASV</b></font></font></h3> <p style="font-variant: normal; letter-spacing: normal; font-style: normal; font-weight: normal; orphans: 2; widows: 2"> <font color="#252525"><font face="sans-serif"><font size="2" style="font-size: 10pt"><b>Adaptive Servo-Ventilation</b>.

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 dioxide.</font></font></font></p> <p style="font-variant: normal; letter-spacing: normal; font-style: normal; font-weight: normal; orphans: 2; widows: 2"> <font color="#252525"><font face="sans-serif"><font size="2" style="font-size: 10pt">Cheyne-Stokes 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> <p style="font-variant: normal;

The RERA algorithm monitors for a sequence of breaths that exhibit both a subtle reduction in airflow and progressive flow limitation. If this breath sequence is terminated by a sudden increase in airflow along with the absence of flow limitation, and the event does not meet the conditions for an apnea or hypopnea, a RERA is indicated.</font></font></font></p> <h3 class="western" style="margin-top: 0cm; margin-bottom: 0cm; border: none; padding: 0cm; font-variant: normal; letter-spacing: normal; font-style: normal; line-height: 160%; orphans: 2; widows: 2; background: #ffffff"><a name="RDI"></a> <font color="#000000"><font face="sans-serif"><b>RDI</b></font></font></h3> <p style="font-variant: normal; letter-spacing: normal; font-style: normal; font-weight: normal; orphans: 2; widows: 2"> <font color="#252525"><font face="sans-serif"><font size="2" style="font-size: 10pt">Respiratory Disturbance Index</font></font></font></p> <h3 class="western" style="margin-top: 0cm; margin-bottom: 0cm; border: none; padding: 0cm; font-variant: normal; letter-spacing: normal; font-style: normal; line-height: 160%; orphans: 2; widows: 2; background: #ffffff"><a name="REMstar_Auto_Flags"></a> <font color="#000000"><font face="sans-serif"><b>REMstar Auto Flags</b></font></font></h3> <p style="font-variant: normal; letter-spacing: normal; font-style: normal; font-weight: normal; orphans: 2; widows: 2"> <font color="#252525"><font face="sans-serif"><font size="2" style="font-size: 10pt">Measurements recorded in 30 second intervals for the following measures: NR = Non-Responsive Apnea/Hypopnea event OA = Obstructive Apnea event H = Hypopnea event FL = Flow Limitation event S = Snoring event AHI = Apnea/Hypopnea Index (the sum of the Apneas and Hypopneas during the night divided by the number of therapy hours).</font></font></font></p> <h3 class="western" style="margin-top: 0cm; margin-bottom: 0cm; border: none; padding: 0cm; font-variant: normal; letter-spacing: normal; font-style: normal; line-height: 160%; orphans: 2; widows: 2; background: #ffffff"><a name="RR"></a> <font color="#000000"><font face="sans-serif"><b>RR</b></font></font></h3> <p style="font-variant: normal; letter-spacing: normal; font-style: normal; font-weight: normal; orphans: 2; widows: 2"> <font color="#252525"><font face="sans-serif"><font size="2" style="font-size: 10pt">Respiration Rate Frequency of breathing, expressed as the number of breaths per minute</font></font></font></p> <h3 class="western" style="margin-top: 0cm; margin-bottom: 0cm; border: none; padding: 0cm; font-variant: normal; letter-spacing: normal; font-style: normal; line-height: 160%; orphans: 2; widows: 2; background: #ffffff"><a name="S.2FT"></a> <font color="#000000"><font face="sans-serif"><b>S/T</b></font></font></h3> <p style="font-variant: normal; letter-spacing: normal; font-style: normal; font-weight: normal; orphans: 2; widows: 2"> <font color="#252525"><font face="sans-serif"><font size="2" style="font-size: 10pt">Spontaneous/Timed therapy mode</font></font></font></p> <h3 class="western" style="margin-top: 0cm; margin-bottom: 0cm; border: none; padding: 0cm; font-variant: normal; letter-spacing: normal; font-style: normal; line-height: 160%; orphans: 2; widows: 2; background: #ffffff"><a name="SD_Card"></a> <font color="#000000"><font face="sans-serif"><b>SD Card</b></font></font></h3> <p style="font-variant: normal; letter-spacing: normal; font-style: normal; font-weight: normal; orphans: 2; widows: 2"> <font color="#252525"><font face="sans-serif"><font size="2" style="font-size: 10pt">A SD Card (Secure Digital Card) is an integrated circuit which is housed in a compact, rugged plastic enclosure.
