How Does A Pulse Oximeter Work?
A pulse oximeter is a medical device that indirectly measures the oxygen saturation of a patient’s blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmograph. It is often attached to a medical monitor so staff can see a patient’s oxygenation at all times. All pulse oximeters also display the heart rate. Portable, battery-operated pulse oximeters are also available for home blood-oxygen monitoring.
The fingertip Pulse Oximeter is indicated for continuous use or spot-checking in measuring and displaying functional arterial oxygen saturation (SpO2) and pulse rate of patients who are well or poorly profuse. It is intended for adult and pediatric patients on fingers between 0.3–1.0 inch (0.8-2.5 cm) thick.
Intended Use:
The fingertip Pulse Oximeter is indicated for continuous use or spot-checking in measuring and displaying functional arterial oxygen saturation (SpO2) and pulse rate of patients who are well or poorly profuse. It is intended for adult and pediatric patients on fingers between 0.3–1.0 inch (0.8-2.5 cm) thick.
Function:
A blood oxygen monitor displays the percentage of arterial hemoglobin in the oxyhemoglobin configuration. Acceptable normal ranges are from 95 to 100 percent, although values down to 90% are common. For a patient breathing room air, at sea level, an estimate of arterial pO2 can be made from the blood-oxygen monitor SpO2 reading. A pulse oximeter is a particularly convenient noninvasive measurement instrument. Typically it has a pair of light-emitting diodes (LEDs) facing a photodiode through a translucent part of the patient’s body, usually a fingertip or an earlobe. One LED is red, with a wavelength of 660 nm, and the other is infrared, 905,910 or 940 nm. Absorption at these wavelengths differs significantly between oxyhemoglobin and its deoxygenated form, therefore, the oxy/deoxyhemoglobin ratio can be calculated from the ratio of the absorption of the red and infrared light. The absorbance of oxyhemoglobin and deoxyhemoglobin is the same (isosbestic point) for the wavelengths of 590 and 805 nm, earlier oximeters used these wavelengths for correction for hemoglobin concentration.
The monitored signal bounces in time the heart beat because the arterial blood vessels expand and contract
Advantages:
A pulse oximeter is useful in any setting where a patient’s oxygenation is unstable, including intensive care, operating , recovery, emergency and hospital ward settings, pilots in unpressurized aircraft, for assessment of any patient’s oxygenation, and determining the effectiveness of or need for supplemental oxygen. Assessing a patient’s need for oxygen is the most essential element to life; no human life thrives in the absence of oxygen (cellular or gross). Although a pulse oximeter is used to monitor oxygenation it cannot determine the metabolism of oxygen, or the amount of oxygen being used by a patient. For this purpose, it is necessary to also measure carbon dioxide (CO2) levels. It is possible that it can also be used to detect abnormalities in ventilation. However, the use of a pulse oximeter to detect hypoventilation is impaired with the use of supplemental oxygen, as it is only when patients breathe room air that abnormalities in respiratory function can be detected reliably with its use. Therefore, the routine administration of supplemental oxygen may be unwarranted if the patient is able to maintain adequate oxygenation in room air, since it can result in hypoventilation going undetected.
Because of the simplicity and speed, pulse oximeters are of critical importance in emergency medicine and are also very useful for patients with respiratory of cardiac problems. Especially COPD, or for diagnosis of some sleep disorders such as apnea and hyperpnoea. Portable, battery operated pulse oximeters are useful for pilots operating in a non-pressurized aircraft above 10,000 feet (12,500 feet in the US) where supplemental oxygen is required. Prior to the oximeter’s invention, many complicated blood tests needed to be performed. Portable pulse oximeters are also useful for mountain climbers and athletes whose oxygen levels may decrease at high altitudes or with exercise, those using portable pulse oximeters are also making use of blood oxygen charting software. These charting methods provide print outs for the patients physician of blood oxygen and pulse, and reminders to check blood oxygen levels.
Why Have A Fingertip Pulse Oximeter?
There are three main reasons for using a pulse oximeter:
Patients:
Those on oxygen therapy use a pulse oximeter to help manage their oxygen flow, these patients include but are not limited to those with COD, Asthma, Emphysema and CHF.
Athletes:
Health and wellness for all athletes is important, and an important part of monitoring one’s health is though using a pulse oximeter to monitor the blood oxygenation. Runners, hikers, climbers as well as all athletes could benefit from monitoring their blood oxygen levels gaining greater benefits in their health regime.
Pilots:
Using a pulse oximeter during flights may help in the prevention of in-flight hypoxia. Studies preformed at the FAA’s Civil Aeromedical Institute, have shown that pilots flying in unpressurized airplanes at altitudes between 8,000 and 12,000 feet without supplemental oxygen, make ore procedural errors than pilots who are well oxygenated. Pilots not receiving oxygen at altitude also made more errors on decent and approach because of the effects of hypoxia.
