OIIXimeter – SPO2/HRV

With the advancement of technology and popularity of smartphone devices, we are now able to monitor our health indicators easier, cheaper and with much greater details that was not possible just 10 years ago. There are several useful health indicators that we can monitor using an advanced finger sensor.

1. SPO2 Oxygen Concentration Indicator:

Blood oxygen saturation (SpO2) reflects the blood oxygen level in blood and is used to indicate changes due to heart or lung function, oxygen used by the body or altitude. Too low a blood oxygen concentration will cause insufficient oxygen supply or reflect a condition that need medical attention.

Concentration Level %Indicator
95-99%Normal
90-95%Insufficient Oxygen Supply
<90%Light Oxygen Supply, seek medical attention
<85%Severe Oxygen Supply, seek immediate medication attention. Can be life threatening if left unattended.

The oximeter, uses photoplethysmogram (PPG) technology to detect the level of oxygen level in blood. The probe uses 2 light sources, red light, and infrared light, which are absorbed by the blood. Higher absorption of infrared light indicates good oxygen saturation, whereas a higher absorption of red light indicates poor saturation. Readings obtained from a pulse oximeter are expressed in percentage.

2. Heart Rate Variable

Heart Rate Variability (HRV) opens out a new window for anyone who’s interested in their health to understand better about their reserved energy. Heart Rate Variability is different from Heart Rate. It simply means is a measurement of fluctuation in time intervals between adjacent heartbeats. The HRV reading is related to your autonomous nervous system, that controls the parasympathetic (relaxation) and sympathetic (stress) signals, and this offers a totally different perspective of your body condition. In general, healthier, people with large reserved energy will usually see much larger fluctuation, whereas weaker, people with low energy reserve will see little fluctuation.

3. Heart Beat (Pulse Rate)

Heart (Pulse) Rate monitoring is the most common type of assessment for one to quickly assess the physical condition of your body. While Pulse Rate is not an absolute indicator of health, it’s good to have some understanding of your baseline – as in your normal resting heart rate. A healthy normal adult heart rate (beats per minute BPM) is between 60-100 bpm. Below 60bpm during resting waking state is categorize as Bradycardia, which cause symptoms like fatigue, dizziness, shortness of breath, etc. due to insufficient blood flow. However its normal for athletics to exhibit much lower BPM. Elites athletics, diver can easily have BPM below 40 and are still perfectly healthy and normal.

On the other hand, fast resting heart rate of more than 100 BPM is known as Tachycardia. Faster doesn’t mean more blood flow, but instead it can disrupt the heart pump mechanism. The rapid heartbeat keeps the heart’s chambers from filling completely between contractions, which compromises blood flow to the rest of the body.

4. Perfusion Index

Perfusion Index (PI) refers to the ratio of the pulsatile blood flow to the non-pulsatile blood in peripheral tissue. It indicates changes in the blood circulation and reflecting the perfusion ability of the pulsate blood flow at the monitoring site. The greater the PI value, the better the limb perfusion. There is not a very clear definition on the normal/abnormal range, but the higher the value, the better it is. Everyone should establish their own baseline, as in HRV reading.

PI monitoring can be applied in clinical setting for predicting incident of hypotension, monitoring of critically illed patients, or effect of anaesthesia.

OIIXimeter 4-in-1 Finger Sensor

OIIXimeter is a 4 in 1 finger pulse oximeter that reads not only your oxygen saturation level of arterial hemoglobin (SPO2), heart rate, blood vessels perfusion index (PI), but also a very useful health indicator known as heart rate variability (HRV). The advanced Digital Signal Processing (DSP) algorithm can minimize the influence of motion artifact, ambient light and improve the accuracy of measurement even at a low blood perfusion situation.

Oximeter-H Mobile Application

It comes with a software application that runs on Android and iOS, the can capture your real-time and historical data on your mobile phone through mobile phone. The data is stored locally on your mobile phone (not cloud), so there is no privacy concern or issue of your health data leaked or misappropriated.

Real-time data is important to understand your current body condition and allow you to take immediate action. Historical data, on the other hand, will be useful for you to understand your overall health over a period of time. OIIXimeter application – Oximeter-H keep tracks of all these critical information for you.
