3. Getting to know your device
The SPO 25 pulse oximeter provides a non-invasive measurement of the arterial oxygen
saturation (Spor) and the heart rate (pulse rate). oxygen saturation indicates the peic-entage of
haemoglobin in adenal blood that is loaded with oxygen. Therefore it is an important parair-
eter for assessing the respiratory {unction. To take a measurement, the pulse oximeter uses
two rays of light wlth differing wavelengths, which strike the finger inserted inside the housing.
A low oxygen saturation varue generailt indicates underlying irlriesses (respiratory diseases, "
asthma, heart fai ure etc,).
People with a low oxygen saturation value are more likely to experience the iollowing symp_
toms: shodness of breath, increased head rate, weakness, neryousness and outbreiki oi
sweating. lf oxygen saturation is known to be chronically drminished, it requires monitorlng us-
ing the pulse oximeter under medical supervision. rfyou have acutery dimihisned oxygen iatu-
ration, with.or without the accompanying symptoms, you must consult a doctor imme'diatety
as it could lead to a life{hreatening situation. The pulie oximeter is pafticularly suitable for
patients at risk such as peopre witi head disease or asthma, but ar;;for athl6tes and neitthy
people who exercise at high altitude (e.g. mountaineers, skiers or amateur pilots).
