Pulse Oximeters for sale:
What is a pulse Oximeter – the simple explanation
When looking at pulse Oximeters for sale, it is best to have a good understanding of how they work, before rushing to look at pulse Oximeters for sale. The small electronic device a nurse attaches to the end of your index finger with a plastic clip calculates how much oxygen is carried in your blood. It’s based on measuring the difference between levels of the red pigment haemoglobin which carries oxygen in your blood. It turns out that oxygenated haemoglobin (“oxyhaemoglobin”) and nonoxygenated haemoglobin (“deoxyhaemoglobin”) in your blood are different colors. That thing on your finger has two light-emitting diodes – one that sends out invisible infrared light and one that sends out red light.
Doctors find this information useful to figure out if your heart/ lungs/ blood are all working together to get oxygen delivered to all the various parts of your body. The test isn’t perfect – for example, you could have poor overall blood flow and still a high level of oxygenation.
A pulse Oximeter monitors the oxygen saturation of a person’s blood in an indirect manner. That means that no blood sample has to be taken. This is also why it is called a non-invasive method. It is used so that a person’s oxygenation can be seen at all times. Many of these monitors also display the heart rate of the person. These monitors can be used at home and are many times battery operated. The first one was already made in the 1940s, and has improved dramatically over the years in terms of accuracy and technology. It is quite amazing to see the advanced pulse Oximeters for sale these days.
So how does a pulse Oximeter work?
A pulse Oxy meter is wonderful technology and this has gotten better and better over the last many years. A pulse Oxy meter basically measures the interference by blood cells with the transmission of light and various wavelengths. The cells cause interference with the transmission of light depending on the presence or absence of oxygen in the red cells.
How is a pulse Oximeter used?
The sensor is placed on a thin part of a person’s body, usually on a fingertip or on a yellow. If it is for use with a baby, it is placed for example across the foot. Like with the red wavelengths and light with infrared wavelengths of them sequentially passed to the patient to a photo detector. The absorbance of each of these wavelengths is measured and the changes and this calculation is then used to calculate the levels of oxygen in the blood.
When would you use a pulse Oximeter?
A pulse Oxy meter is useful in many settings for example where patients oxygenation is unstable including when a person is in intensive care and such a person needs to be monitored on a constant basis.
Do pulse Oximeters work well?
These monitors are extremely accurate to the measure of persons oxygenation. It does not however measure the ventilation and therefore laboratory tests need to be done in order to determine the ventilation of the person.
False readings can also be obtained for a number of reasons, and it is important that you follow the instructions carefully when using this monitor.
Some good examples of the good use of pulse Oximeters
Pulse Oxy meters may be used and are ideal situations one good example is the monitoring of oxygenation and pulse rates throughout operations when a person is under anaesthesia. They are widely used in intensive care at operating environments recovery emergency and general hospital ward environments. Home use of pulse Oximeters of increasing typically under the instruction of medical practitioners.
