The Summary Graphs Tab

Summary data is gathered by the therapy device and stored in internal memory. It can be copied
from there to a data card, or retrieved directly for display in ResScan. The information classed as
summary data is:

Usage data—summarizes duration of delivered therapy

Respiratory indices—summarizes detected respiratory events such as apneas and
hypopneas into ratios such as Apnea Index (AI) and Apnea–Hypopnea Index (AHI)

Statistical treatment—summarizes the statistics computed on treatment parameters such as
leak and respiratory rate.
The data displayed in the Summary tab will depend on the therapy device used. Traces
displayed may include:

Usage (Hrs: Min)

Pressure (cm H O or hPa) – Mean, Inspiratory, Expiratory


Leak (L/min or L/sec)

Apnea or Hypopnea events

AHI and AI (Events/hr)

Minute Ventilation (L/min) and Target Ventilation

Respiratory Rate (breaths/min)

Tidal Volume (L/min)

I:E Ratio (%)

Prescribed Pressure—IPAP, EPAP (cm H

% Spontaneous Triggered Breaths

% Spontaneous Cycled Breaths.
