Hypertension – causes, prevention and treatment
Hypertension, or high blood pressure, is a persistent blood pressure above 90 mm Hg between the heart beats (diastolic) or over 140 mm Hg at the beats (systolic). The blood pressure varies naturally in response to stress and physical work load. Therefore the blood pressure shall be measured in a relaxed situation and several times before this diagnosis is certain.
Hypertension does not in itself give dramatic symptoms, but it is perilous because it causes a highly increased risk for heart infarction, stroke and renal failure.

The Technology Behind Finger Pulse Oximeter Devices And Choosing The Right Pulse Oximeters For Sale
A Pulse oximeter is a instrument with the purpose of measuring oxygenation of blood by measuring the oxygen percentage in haemoglobin. It is usually attached to the lobe of the ear or fingertip and records the flow of blood past a probe in the unit. Some units make a sound or graph which coincides with the pulse beat.
650nm & 805nm are the wavelengths of light usually utilized in an oximeter’s probe to record absorption and saturation of the haemoglobin in a patient’s blood. Oxygenation in the blood is measured by this saturation level measured. Slow blood flow may introduce problems in normal pulse oximeter functions due to the units mechanism of measuring blood flow.
