What is transcutaneous oximetry for?
Transcutaneous oximetry (TCOM or tcpO 2 ) is a non-invasive and painless examination, which therefore allows to evaluate the amount of oxygen transported by the blood and transferred from the capillaries to the tissues, providing doctors with essential indications of prognosis, diagnosis, and therapy.
How to read the oximeter data?
- Mild, when the values detected by the oximeter are between 91% and 94%;
- Moderate, when the oximeter detects values between 86% and 90%;
- Severe, when the oximeter reports values equal to or less than 85%.
What does the oximeter graph indicate?
Finger
pulse oximeter: where to buy it and at what price Color monitor that simultaneously shows the percentage of hemoglobin saturated with oxygen and the number of average pulsations per minute with a graph showing the trend in real time.
How do you write saturation?
SpO2%: the pulse oximeter measures oxygen saturation
The purpose is to detect the physiological saturation of the patient and to act promptly in case of hypoxia (by administering Oxygen therapy for example).
What does oximetry mean?
Oximetry is a test capable of detecting the amount of oxygen present in arterial blood and is conventionally done with an electronic instrument called an oximeter or oximeter.

Why is blood oxygen important?
What is blood oxygenation?
The oxygen molecules reach the cells of our organism and inside them occurs the so-called “cellular respiration” which allows the production of energy.
What does the finger pulse oximeter measure?
The oximeter is the small device with which it is possible to measure the oximetry, that is the amount of oxygen linked to hemoglobin in the blood (blood oxygenation) in relation to the total amount of circulating hemoglobin.
When is saturation worrying?
WHAT ARE THE VALUES REPORTED BY THE SATURIMETER? Normal oxygenation values (reported as SpO2) range from 97% up – but up to 94% are of no concern, especially in patients with known lung disease.
How to measure oxygen with oximeter?
How is the oximeter used? The operation of this tool is very simple: just turn it on, insert your finger all the way, so that the LED illuminates the central part of the nail, and wait a few seconds for the oxygen saturation and heart rate readings.
How does the Samsung pulse oximeter work?
The process of measuring SpO2 with a Samsung mobile phone
This measurement is done specifically with a series of pulses on the finger, where it is positioned, to measure blood saturation. They are exact measurements, just like all Samsung models just by holding the device in your hand.
How much should the blood oxygenation be?
For adults, the normal range of sao 2 is 95 – 100%. A value lower than 90% is considered low oxygen saturation, which requires external oxygen supplementation.
How Much Should the Oximeter Measure?
Physiologically, saturation has normal values between 95 and 100%. If it falls below 95% we speak of a state of hypoxia, which can be: mild, when the values detected by the oximeter are between 91% and 94%; moderate, when the oximeter detects values between 86% and 90%;
How to measure saturation with Apple watch?
Open the Levels O₂ app on Apple Watch. Rest your arm on a table or on your legs, and make sure your wrist is level, with the Apple Watch screen facing up. Tap Start, then hold your arm still during the 15-second countdown. When the measurement is complete, you will receive the results.
What happens when saturation is low?
A reduced amount of oxygen in the blood can lead to hypoxemia. This condition involves manifestations such as pallor of the skin and mucous membranes (cyanosis), hyperventilation and dyspnea, as well as generating a state of confusion and disorientation.
What to do in case of low saturation?
If the saturation falls below 90% we are in the presence of a serious situation and it is necessary to intervene promptly by administering oxygen or, in the most serious cases, with assisted ventilation. Desaturation can also arise in the absence of respiratory diseases, for example after physical exertion.
What causes the lack of oxygen in the blood?
Pulmonary causes include sleep apnea, pneumonia, pulmonary embolism, and respiratory failure. Hypoxia is also observed in patients with atherosclerosis, angina, heart attack, stroke, anemia, head trauma and rib fractures.
What is oxygen in cells for?
To ensure the production of energy by the cells, all the tissues of the human body need a constant supply of oxygen. When we inhale, oxygen travels through the upper respiratory tract until it reaches the most minute components of the respiratory system, the pulmonary alveoli.
Why does little oxygen dissolve in the blood?
Hypoxia can also result from a reduced concentration of hemoglobin in the arterial blood. Conditions that decrease the amount of hemoglobin in red blood cells or their number negatively affect the blood’s ability to carry oxygen.
How to measure oxygen saturation with cell phone?
HemaApp is therefore an innovative app that, through the use of the smartphone flash, is able to detect whether a person is anemic or not. In fact, it is sufficient to activate the application, place a finger on the rear camera flash and wait for the response.
How to measure blood pressure with Apple Watch 6?
- Open the Qardio App on your Apple Watch.
- Unroll the QardioArm sleeve and pull the tab. Pass your arm through the opening and close the cuff.
- Tap the START button to start the measurement.
When is oxygenation low?
between 92 and 90% means that oxygenation is insufficient and it is advisable to undergo blood gas analysis (EGA); there are some exceptions in which values around 90% may be normal, for example in patients suffering from chronic obstructive pulmonary disease (COPD)
How high should the saturation be in the elderly?
In the young non-smoker in a sitting position, the PaO2 is between 95-100 mmHg, in an elderly person (> 65 years) around 80 mmHg.
How to increase the level of oxygen in the blood?
A natural remedy to replenish the body with oxygen is through oxygen supplemented water. The oxygen is thus absorbed directly in the stomach and intestines, rapidly increasing saturation. The water that contains the most oxygen in the world is Oxygizer → DISCOVER OXYGIZER.
How to tell if there is a lack of oxygen?
On the other hand, if oxygen is totally absent, there is anoxia. Hypoxia is often accompanied by confusion, shortness of breath, headache, dizziness, tachycardia, vision problems, cyanosis, increased pressure and breathing rate, loss of coordination in movement.
How does a color get saturated?
The saturation of a color depends on the intensity of the light and the spectrum of wavelengths over which it is distributed. Pure color is achieved when the light is on a single wavelength (as in the case of the laser).
