Older age people, patients with breathing disorders need regular monitoring of oxygen levels to avoid any unpleasant emergencies. A portable oximeter is a great affordable option as you don’t have to go to a medical practitioner every time.
If you want to buy a budget oximeter from a trusted brand Dr trust Oximeter can be a great option for you.
What is an Oximeter?
An oximeter is a device by which we can measure the oxygen saturation in the blood. Further, It can give continuous updates on change in the oxygen levels of your blood. You can easily clip this device to any of your fingers without any pain. It comes in handy when there is a chance of a drop in oxygen level due to heavy physical work. Except this, High altitude climbers & people with respiratory issues also need continuous monitoring of their blood oxygen levels.
Working of an Oximeter
Basically, any Oximeter detects the oxygen saturation in blood by measuring the change in red & Infrared lights’ wavelength when it passes through the blood sample, i.e., when your finger is sandwiched between the device’s clips.
Furthermore, Let understand it in detail so that you can decide its use & importance for you.
An oximeter is a clip shaped device. One side of this clip has two different types of lights sources :
- Red light, &
- Inferred light
The other side of the Oximeter contains a light detector.
So, Now here is what happens inside,
1. As we power On the Oximeter, the lights inside the clip get illuminated.
2. These lights, when passes through your figure tip, get absorbed by the Hemoglobin present in the blood.
3. Only some amount of this light gets to pass through the finger. Which then reaches the other side of the clip to get detected by the light detector.
4. Consequently, the changes in this light give the essential data for telling the blood’s oxygen level.
The concept of using the change in properties of light to tell the oxygen level of blood
The amount of light that is absorbed by the finger depends on many physical properties of light. Further, these properties are used by the pulse oximeter to calculate the oxygen saturation.
The amount of light absorbed depends on the following criteria:
1. The concentration of the light-absorbing substance – Beer’s law
Hemoglobin has a property to absorb light rays. So, when light from the Oximeter passes through the blood vessel, hemoglobin present in the blood absorbs the light. This absorption of light is directly proportional to the amount of Hemoglobin in your blood.
The whole concept is based on Beer’s Law, which says that “The Amount of light absorbed is proportional to the concentration of the light-absorbing substance.
This law helps the Oximeter to determine the amount of Hemoglobin present in the blood.
2. Length of the light path in the absorbing substance – Lambert’s law
Human Body is consist of arteries of different thickness. So, the light will have to cover a shorter path in the narrow artery and travels through a longer route on the broader artery. However, hemoglobin density remains the same; light encounters more Hemoglobin on the broader artery and gets absorbed more than a narrow one.
This phenomenon is known as Lambert’s Law, which says that “ The Amount of light absorbed is proportional to the length of the path that the light has to travel in the absorbing substance.”
3. Oxyhemoglobin and Deoxyhemoglobin absorbs red and infrared light differently
There are two types of Hemoglobin present in human blood–
- Oxyhemoglobin: It contains oxygen in it.
- Deoxyhemoglobin: It doesn’t contain oxygen in it.
When red light & inferred light passes through blood, Oxyhemoglobin & Deoxyhemoglobin respond differently to it. Oxyhemoglobin absorbs more infrared light than red light. And the Deoxyhemoglobin absorbs more red light than inferred light.
The pulse oximeter works out the oxygen saturation by comparing how much the blood absorbs red light and infrared light. Depending on the amounts of Oxyhemoglobin and Deoxyhemoglobin present, the ratio of the amount of red light absorbed to the amount of infrared light absorbed changes. Using this ratio, the Oximeter can then be able to determine the oxygen saturation in the blood.
Now, we hope that you have understood all the standard technicalities of Oximeter. Finally, let’s review the latest Doctor Trust oximeter & were to buy it at the Best price.
Features & Specs of Doctor Trust oximeter & its usage
Dr trust Oximeter features hospital-grade precision sensors for easy and clinically accurate results. It is a quick & precise method to check Pulse Rate (PR), Blood Oxygen Saturation (SpO2), and Pulse Bar Graph readings within 5-8 seconds.
Doctor trust oximeter has a simple one-button design that allows for easy operation. The small portable size of the Dr trust Oximeter makes it very easy to handle and carry. It is highly beneficial for athletes and pilots to obtain quick and accurate oxygen saturation readings.
The main features and usage of docter trust oximeter are :
SpO2 & Pulse Measurement
Dr Trust Oximeter is designed for the non-invasive measurements of the pulse rate & Arterial Blood Oxygen Saturation (SpO2). This device shows a real-time reading within 6 seconds and shuts down automatically when you remove your finger.
We can use this Doctor trust Oximeter to count the number of breathing cycles in one minute while at rest. A fluctuated rate may lead to bradypnea, apnea, or tachypnea.
Perfusion Index (PI)
PI indicates the pulse strength at the sensor site. While a regular pulse rate in waveform graph ensures the reliability of the readings
This Doctor trust oximeter works well with all age groups and the best for offering pediatric care. The small, compact, and innovative design comes with eight modes to display SpO2, PR pulse measurements quickly and accurately on a wide dual-color and multi-directional OLED display.
Robust Hypoallergenic Design
A high-quality ABS material makes Doctor trust oximeter very durable. Hypoallergenic latex-free material is coated inside the finger chamber, making it anti-allergic for all those with sensitive skin. While with the provided lanyard, it is easy to carry securely during travel.
IP22 with Low Power Indication
Dr Trust Oximeter is water-resistant but not waterproof. It requires 2 AAA alkaline batteries and indicates when the battery is low.
The fingertip clip of Doctor trust oximeter is soft and comfortable to apply on different body parts and a wide range of finger sizes. It is comfortable to use without taking a blood sample from an artery. A buzzing alarm sounds when your measurements do not reach the standard point.
This device records SpO2 and pulse rate during a medical emergency or intensive care. Doctor trust oximeter is widely used in clinics, hospitals, and homes to record vital signs of patients with respiratory issues like COPD, COAD, emphysema, asthma, etc.
This Dr trust Oximeter helps you to know about your asthma trigger and prevent hypoxia. Hypoxia is a common health condition faced by skiers, athletes, mountain climbers, pilots, and other people who go to high altitude areas. In such cases, the level of blood oxygen drops down suddenly.
The measurement numbers in Doctor trust oximeter ranges from 0 to 100% of oxygen saturation in the blood. In ideal conditions, the oxygen levels are supposed to be at 100%. Due to degraded environmental conditions & an unhealthy lifestyle, it can be 97-100 for a healthy person. If the oxygen levels fall beyond that, you need to see your doctor immediately.
Dr Trust Oximeter has an accuracy of ±2 units.
