Uses and Benefits of Pulse Oximeters

A pulse oximeter is a device intended for the non-invasive measurement of arterial blood oxygen saturation (SpO2) and pulse rate. Oximeters are widely used in hospitals, medical clinics, operating rooms, and homes. Both oxygen saturation level and pulse rate are vital signs of a patient.

Pulse oximeter is used medically by patients with asthma, chronic obstructive pulmonary disease (COPD), chronic obstructive airway diseases (COAD), and other respiratory conditions. Patients with serious respiratory problems should have their SpO2 levels check regularly and especially if they are not feeling well.

Patients with serious cardiac condition would often experienced low SpO2 levels. Pulse oximeters would help them to monitor their conditions and use supplementary oxygen when required. Pleth graph produced by a pulse oximeter shows the change in blood volume during a heart pulse is often a good indication of certain heart conditions.

Pilots and mountain climbers use pulse oximeters to help guard against hypoxia.

Pulse oximeter can also help athletes in high altitude training. The reduction in oxygen level can increase red blood cells in athletes and help to increase his/her endurance.
