Pulse oximeters are devices designed to be positioned on a finger to get in few seconds the blood-oxygen saturation (Sp02) level, expressed as a percentage. Values above 95% are to be considered natural, and therefore generally good, while the lower they get under that threshold the critical they are (a poorly oxygenated blood does not properly nourish body tissues and organs). Sp02 is an important parameter for the prevention of critical conditions affecting internal tissues and organic functioning, providing important information to the physician on the possible presence of serious pathologies such as: heart failure, arterial stenosis, ARDS (acute respiratory distress syndrome), COPD (chronic obstructive pulmonary disease), pulmonary emphysema, congenital heart defects, cystic fibrosis, critical conditions caused by drugs (allergy or overdose). More over, the use of a pulse oximeter may be crucial to monitor extreme activities, such as mountaineering at high altitudes or scuba diving, in order to avoid dangerous situations.If you need to regularly monitor your SpO2 levels or pulse rate due to a health condition, the mx Health Fingertip Pulse Oximeter is a valuable accessory for daily tracking. Simply insert your index finger into the oximeter, switch it on, and it will instantly and non-invasively measure the oxygen saturation of arterial haemoglobin in your blood. This compact device is equipped with a large LED screen for easy readings and is designed with low power consumption, making it ideal for spot checks wherever you go and as often as you need.
