The Polymate
®
uses sensors to record oxygen saturation, pulse rate, airflow, respiratory effort,
snore, and body position in a supervised (hospital/institutional) or unsupervised (home)
environment. It is capable of recording at least 8 consecutive hours of patient data. Serial cables
allow the Polymate
®
to transfer the data from Polymate
®
to the hose PC. CPAP pressure cannula
allow the Ploysomnograph to record data from these pressure therapy device:

CPAP or APAP.
Oxygen saturation and pulse measurements are made by a SpO
2
sensor with two light-emitting
diodes (LEDs) that send red and infrared light through tissue containing an arterial pulse. The
light is received by a photo detector that is located directly opposite the LEDs.
Respiratory effort measurements are made by a chest and abdomen effort sensor attached to
electrodes on the patient’s chest and abdomen area.
Airflow measurements are made by an Oral and Nasal airflow Cannula that is placed just inside
the patient’s nose or a CPAP pressure cannula that is used in conjunction with a nasal mask
during CPAP therapy.
