Pulse Oximeter(Add on special)

$26.00 SGD $59.99 SGD

Blood oxygen saturation, pulse rate and perfusion index portable fingertip pulse oximeter that delivers fast and accurate Sp02, PR, PI, RR and Plethysmogram readings within 10 seconds.

Simply place your finger inside the anti-slip silicone chamber of the pulse oximeter and press the button. Your oxygen saturation level, pulse rate, perfusion index, respiratory rate and Plethysmogram will be displayed on the OLED screen.

Safe for use on children >4 years to adulthood.

Reasons for possible inaccurate readings

  • Cold hands - warm your hands and fingers before taking readings. You can simply do this by rubbing your hands together.
  • Keep your hands still - movement may cause the device to reset its reading.
  • Nail polish and false fingernails may also cause false readings.

Oxygen Saturation Levels(Sp02)

A healthy human person should be able to achieve normal blood oxygen saturation of 94% to 99% consistently. For patients with mild respiratory diseases, the reading should be 90% or above. Supplementary oxygen should be used if levels falls below 90%

SpO2 is the measure of amount of oxygen carrying haemoglobin in the blood relative to the amount of haemoglobin not carrying oxygen. Our bodies require a certain level of oxygen in the blood or it will not function as efficiently.

Range reading - 70-99%, +-2% accuracy


Pulse Rate(PR bpm)

A normal resting heart rate for adults ranges from 60 to 100 beats per minute.

A lower heart rate at rest implies more efficient heart function and better cardiovascular fitness.

Range reading - 30-240 bpm, +-1bpm accuracy


Perfusion Index(PI %)

A higher perfusion index(20%) means greater blood flow to the finger and a lower index(0.02%) means lower blood flow to the finger.

PI is the ratio of the pulsatile blood flow to the nonpulsatile or static blood in peripheral tissue.

Range reading - 0.2-30%, +-1% accuracy


Respiratory Rate(per minute)

Respiratory rate is the number of breaths you take per minute. Normal rate for an adult at rest is about 12 to 20 breaths per minute. A rate under 12 or over 25 breaths per minute while resting is considered abnormal.



Measures changes in volume of arterial blood with each pulse beat. Please see diagram below for more reference. 

Please consult a certified doctor at any time. And see a doctor immediately if unwell.
