How to improve Oximeter Signal and Get Accurate Results
Pulse oximeter is a non-invasive procedure to measure the level of oxygen and heart
beat accurately. These are vital parameters of the body, in case if the oxygen level falls
below the normal level it can lead to death.
In ancient times, before the invention of pulse oximeter device invasive procedures were
used to measure oxygen level in blood. The procedure was not only painful, but was time
consuming. Oximeters are handy in nature and the level of oxygen in blood can be
measured accurately. As the device is compact in nature it can be carried anywhere
There are few things that need to be followed while using a pulse oximeter to ensure
that you get accurate output at all times. In this article we will discuss the things you
need to follow and let’s discuss it one by one.
(a)When taking readings make sure the probe is always straight. In case, if it is bend or
twisted it can give false readings. If you feel again the output is inaccurate you can try
to change the probe.
(b) Nail polish has to be removed from the finger; normally the polish prevents the light
waves to enter the finger. A nail polish remover can be used to remove it completely.
Apply the probe only after clearing the polish otherwise it would lead to inaccurate false
(c) Topical vasodilator cream such as glyceryl trinitrate (GTN) cream can be applied on
the finger or ear lobe. This will help to get accurate readings at the output.
(d) The skin has to be kept warm before fixing the pulse oximeter device, if possible try
to rub the area of the skin to make it warm before fixing the oximeter device.
(e) Environmental interference can also change the values and lead to false outputs. Any
electronic devices such as mobile phones, receivers, transmitters, etc has to be kept at
bay before using oximeter.
(f) Another common cause for inaccurate output is the use of intravascular dyes. Wrong
readings can be caused temporarily due to these dyes. Methylthioninium chloride is the
most commonly used intravascular dye that interrupts with readings.
(g) Bright lights can also lead to false readings in the pulse ox unit. Infrared heat lamps
and ambient lights have to be kept away from the oximeter device to prevent the
occurrence of false readings.
Moreover always buy the device from a reputed supplier and this would ensure that you
a get a quality device. Also look for FDA certification in the device and the certified
devices are trustworthy and provide accurate readings at all times.
Author Bio: When you buy pulse oximeter make sure it is FDA certified. Pulse
