Blood oxygen meter finger
The level of oxygen in the blood:
our bodies need oxygen to function, oxygen enters the body through the nose and mouth, and passes through the lungs into the bloodstream, once the oxygen reaches the bloodstream, it helps provide energy to our bodies, supports the way our immune system works and more A blood oxygen level test, also known as a blood gas analysis, measures the amount of oxygen and carbon dioxide in the blood. When you breathe in, your lungs take in oxygen (inhale) and exhale carbon dioxide (exhale).
If there is an imbalance in the levels of oxygen and carbon dioxide in the blood, it may mean that your lungs are not working well. The blood oxygen level test also checks the balance of acids and bases, known as the pH balance in the blood, it may mean that there is too much acid in Blood or little of it that there is a problem in the lungs or kidneys.
Normal blood oxygen level:
If you use a pulse oximeter to measure the level of oxygen in the blood, the normal reading is, the Sp02 level is between 95 and 100 percent. However, this may differ for people with certain medical conditions, such as diseases. Lung, talk to your doctor to determine what is "normal" for you and remember that these devices at home are easy to use and non-invasive, but they are not 100% accurate. The oxyhemoglobin dissociation curve always becomes steeper than 90%, reflecting the desaturation velocity, which occurs with decreasing oxygen partial pressure (PaO2), in most devices, the default oxygen saturation drop alarm setting is 90%, no Pulse oximetry provides information on the oxygen content in the blood or on ventilation, and therefore, care is needed if anemia is present and in patients with respiratory failure, due to carbon dioxide retention.
What is a pulse oximeter?
A pulse oximeter or pulse oximeter: A device that measures oxygen saturation in arterial blood, using a sensor usually attached to a finger, toe, or ear to determine the percentage of oxyhemoglobin (oxyhemoglobin) in the pulsating blood through a network of capillaries. It quickly detects, even small changes, in how efficiently oxygen is transported to the extremities farthest from the heart, including the legs and arms, and is often used in critical care settings such as emergency rooms or hospitals. Some doctors, such as pulmonologists, may use it in the office The first known use of a pulse oximeter was in 1986.
Purpose and uses of a pulse oximeter:
The purpose of pulse oximetry is to check how well your heart is pumping oxygen through your body, it can be used to monitor the health of individuals with any type of condition that can affect oxygen levels in the blood, especially while they are in the hospital These conditions include: chronic obstructive pulmonary disease. Asthma. Pneumonia. Lung cancer. Anemia. Heart attack or heart failure.
In congenital heart defects, there are a number of different common use cases for pulse oximetry, including: To assess how well a new lung drug is working. To assess whether someone needs help with breathing. To assess the usefulness of a ventilator. To monitor oxygen levels during or after surgeries that require anesthesia. To determine the effectiveness of supplemental oxygen therapy, especially when the treatment is new. To assess a person's ability to tolerate increased physical activity. To assess whether a person temporarily stops breathing during sleep, such as in sleep apnea, during a sleep study.
Pulse oximeter working principle:
the principles of pulse oximetry, oximeters work according to the principles of spectrophotometry, meaning the relative absorption of the color of red (absorbed by the deoxygenated blood), and infrared radiation (absorbed by the oxygenated blood), the light of the constrictive component is related For the absorption waveform, with oxygen saturation in the arterial blood, measurements of the relative absorption of light are made several times every second, and are processed by the device to give a new reading every (0.5 - 1 second) which calculates the average readings during the last three seconds. Two diodes, emitting red and infrared light, are placed opposite their detectors through (5-10 mm) of tissue. The probes are usually placed on the fingertip, although earlobes and forehead are used as alternatives in some Sometimes, one study suggested that the earlobe is not a reliable site for measuring oxygen saturation, however, a recent study called for its use in patients admitted to intensive care units for coronary artery bypass surgery.
During a pulse oximetry reading, a small clip-like device is placed on the finger, earlobe or toe, small rays of light pass through the blood in the finger, to measure the amount of oxygen in the blood, it does this by measuring changes in the absorption of light in the oxygenated blood (contains Oxygen) or deoxygenated (devoid of oxygen), this is a painless process, so the pulse oximeter will be able to tell you the levels of oxygen saturation with your heart rate.
Steps to take a pulse oximeter:
A pulse oximeter can be used in both inpatient and outpatient settings, in some cases, your doctor may recommend that you have a pulse oximeter for home use, the most common process for pulse oximetry is for you to place a clip-like device On your finger, earlobe or toe, you may feel a little pressure, but there is no pain or a pinch, in some cases, a small probe can be placed on your finger or forehead with adhesive material, you may be asked to remove your nail polish if it is attached to your finger, you will keep With the probe running for as long as possible to monitor your pulse and oxygen saturation, when monitoring the capabilities of physical activity, this will be during the range of exercise and during the recovery period, during surgery the probe will be pre-attached and removed as soon as you wake up, and you are no longer supervised, sometimes, it will only be used to take a reading One very quickly, once the test is over, the clip or probe will be removed.
Sources of error in pulse oximetry readings: Pulse oximetry cannot differentiate between different forms of hemoglobin, for example, (Carboxyhemoglobin) was recorded as 90% oxygenated hemoglobin and 10% as unsaturated hemoglobin, which causes overestimation of levels of hemoglobin. True saturation. Ambient environmental conditions, such as vibration at (0.5 - 3.5 Hz) and excessive movement by the patient, ambient light including infrared heat lamps make a difference of less than 5%. Cold hands, if local perfusion is impaired. Nail polish should be removed as it may cause false readings. Intravascular dyes, such as methylthioninium chloride, may temporarily reduce saturation readings.
Advantages or pros of pulse oximetry:
The advantages of pulse oximetry include that it is non-invasive, simple and can be used to assess trends (assessment of oxygenation during exercise, sleep, and during procedures). Monitor oxygen saturation over time. Warning of dangerously low oxygen levels, especially in newborns. Providing peace of mind for people with chronic respiratory or cardiovascular disease. Assessment of the need for supplemental oxygen. Monitor oxygen saturation levels in people under anesthesia. It indicates dangerous side effects in people who are taking drugs that affect breathing or oxygen saturation.
Disadvantages or disadvantages of pulse oximetry:
The disadvantages of pulse oximetry include that it cannot be used to assess oxygen delivery (anemia) or adequacy of ventilation (PaCO2), and this accuracy decreases in the presence of elevated levels of dysfunctional hemoglobin (CoHb metHb). Reduces the accuracy of the pulse oximeter reading, including: changes in pulse. Carbon monoxide poisoning, which may not produce pulse oximeter stimulation. Bilirubin levels. Fats in the blood plasma. Interference from external light or color, including nail polish. Cold hands or poor circulation. People who use a pulse oximeter to monitor oxygen saturation should not rely on an oximeter as a substitute for subjective experience. People who experience difficulty breathing, shortness of breath, dizziness, or other signs of possible hypoxia should seek medical attention.
