Pulse oximetry probes placed peripherally may fail to give accurate values of blood oxygen saturation when the peripheral circulation is poor. Because central blood flow may be preferentially preserved, we investigated the oesophagus as an alternative monitoring site. A reflectance blood oxygen saturation probe was developed and evaluated in 49 patients undergoing cardiothoracic surgery. The oesophageal pulse oximeter results were in good agreement with oxygen saturation measurements obtained by a blood gas analyser, a CO-oximeter and a commercial finger pulse oximeter. The median (IQR [range]) difference between the oesophageal oxygen saturation results and those from blood gas analysis were 0.00 (-0.30 to 0.30 [-4.47 to 2.60]), and between the oesophageal oxygen saturation results and those from CO-oximetry were 0.75 (0.30 to 1.20 [-1.80 to 1.80]). Bland-Altman analysis showed that the bias and the limits of agreement between the oesophageal and finger pulse oximeters were -0.3% and -3.3 to ...

BACKGROUND--The British Thoracic Society report on the diagnosis and treatment of the sleep apnoea/hypopnoea syndrome (SAHS) suggests that, if the pulse oximetry baseline oxygen saturation is above 90%, then 15 4% oxygen desaturation/hour in bed will diagnose SAHS requiring treatment. The diagnostic outcome of applying these guidelines has been studied. METHODS--One hundred patients referred to a district general hospital sleep clinic were recruited. After initial clinical assessment, overnight pulse oximetry measurements were performed, followed by full polysomnography at the regional laboratory. RESULTS--Sixty nine patients underwent both pulse oximetry and polysomnography. All 10 patients with more than 15 4% desaturations/hour on pulse oximetry had SAHS confirmed on polysomnography (specificity = 100%). Twenty two patients with SAHS were misdiagnosed using pulse oximetry alone (sensitivity = 31%). These patients had low apnoea scores but high hypopnoea scores. CONCLUSIONS--The BTS pulse ...

Congenital heart disease is a relatively common disease seen in 8/1,000 live births. Many of these diseases are associated with hypoxemia. Hypoxemia results from the mixing of pulmonary and systemic blood or from the mixing of parallel circulations as seen in transposition of the great vessels. Pulse oximetry can be used to measure hypoxemia. Pulse oximetry estimates oxygen saturation by measuring absorption of light in human tissue beds. The amount of light absorption varies depending on the amount of deoxygenated blood in the tissue measured. Measuring the changes in light absorption allows for an estimation of arterial oxygen saturation and therefore the amount of hypoxemia. Most manufacturers claim a confidence interval of 4% for their oximeters. There have been a few studies recently describing the presenting pulse oximetry of known congenital heart disease. However, these were small studies with a small sample size of patients. Moreover, there is no literature describing the hourly ...

There Are Four Main Types Of Pulse Oximeter. Pulse oximeter is a device that are used to measure amount of oxygen in the blood. It consists of a monitor in which oxygen levels is seen in percentage values. Red blood cells absorb the light which is measured by the other side of the probe. An average amount of several pulses must be detected in order for the oximeter to work. Low blood and a weak pulse leave the pulse oximeter to detect inaccurate results.. There are four main types of pulse oximeter: bedside, wrist, hand held and finger type. Each type has several of models to choose from. A bedside oximeter is typically used in stationary medical facility and suited for non ambulatory patients such as those who are chronically ill. Wrist oximeter is those usually used by individuals involved in sports activities and is used for sleep monitoring.. The handheld type can be seen in hospital. It is commonly used in doctors offices and emergency medical services because of its portability and ...

The present study reconfirms the known risk factors for postoperative delirium which are old age, altered cognitive function, and neurological or psychiatric disease [4, 20, 21]. Beyond this, the study identifies preoperative cerebral oxygen saturation (ScO2) measured with near-infrared spectroscopy as an important predictor of postoperative delirium. This finding is in line with observations of Morimoto and colleagues [17], who showed a relationship between preoperative ScO2 and the incidence of postoperative delirium in a small cohort of non-cardiac surgical patients.. Regarding the technical basis of the method, cerebral oximetry is based on the characteristic of hemoglobin to change its absorbtion spectrum with the degree of oxygenation [22]. Two wavelengths of visible and near-infrared light are used to determine the fraction of oxyhemoglobin in a small region of the frontal lobe. According to the blood distribution in cortical brain tissue, regional cerebral oxygen saturation is a ...
The SafeBoosC trial showed that cerebral oximetry combined with a treatment guideline can reduce the the burden of hypoxia in neonates by 50% [Brit. Med. J.350, g7635 (2015)]. However, guidelines based on oximetry by one oximeter are not directly usable by other oximeters. We made a blood-lipid phantom simulating the neonatal head to determine the relation between oxygenation values obtained by different oximeters. We calculated coefficients for easy conversion from one oximeter to the other. We additionally determined the corresponding SafeBoosC intervention thresholds at which we measured an uncertainty of up to 9.2% when varying hemoglobin content from 25μM to 70μM. In conclusion, this paper makes the comparison of absolute values obtained by different oximeters possible. ...
The purpose of this his post-market, observational study titled Verification of Pulse Oximetry in the Neonatal Population is to gather data to further support the accuracy of Nonins pulse oximeters when used in the neonate population. Neonates who are currently undergoing arterial blood gas (ABG) sampling, as part of their medical care will be recruited to participate in this study for collecting opportunity samples. Nonins PureLight® noninvasive sensor will be applied to a foot of the neonate; an adhesive wrap secures the sensor to the neonate. The sensor immediately begins obtaining SpO2 and pulse rate measurements which are sent to the oximeter module for display on the Electronic Data Collection System (EDCS). At the time the prescribed ABG is drawn, the EDCS must have a marker captured to identify the end of the ABG for SpO2 comparison. The SpO2 accuracy of pulse oximeter will be measured by comparing SpO2 readings of the pulse oximeter to values of SaO2 (opportunity samples) determined ...

February 14, 2008 - Masimo yesterday said the University of California at San Francisco Medical Center completed its system-wide implementation of Masimo SET pulse oximetry and the Masimo Rainbow SET technology platform, making it the first hospital to implement Rainbow SET capabilities system-wide.. UCSF Medical Center said it performed a pulse oximetry comparison and evaluation spanning virtually every department and found that Masimo SETs obtained accurate and reliable oxygen saturation measurements under difficult conditions, including patient motion and low perfusion, as the chief reason for conversion to Masimo SET. As part of the evaluation, UCSF clinicians utilized new Masimo Rainbow SET technology to noninvasively and continuously measure physiologic and hemodynamic components that were previously only available by invasive tests. As a result, UCSF decided to expand the adoption of Masimo technologies beyond pulse oximetry to include the noninvasive patient monitoring capabilities. ...

Pulse Oximetry What is pulse oximetry? Pulse oximetry is a test used to measure the oxygen level (oxygen saturation) of the blood. It is an easy, painless measure of how well oxygen is being sent to parts of your body furthest from your heart, such as the arms and legs. A clip-like device called a probe is placed on a body part, such as a finger or ear lobe. The probe uses light to measure how much oxygen is in the blood. This information helps the healthcare provider decide if a person needs extra oxyg...
Heart surgery patients are more at risk of poor peripheral perfusion, and peripheral capillary oxygen saturation (SpO2) measurement is regular care for continuous analysis of blood oxygen saturation in these patients. With regard to controversial studies on accuracy of the current pulse oximetry probes and lack of data related to patients undergoing heart surgery, the present study was conducted to determine accuracy of pulse oximetry probes of finger, toe, forehead and earlobe in detection of oxygen saturation in patients admitted to intensive care units for coronary artery bypass surgery. In this clinical trial, 67 patients were recruited based on convenience sampling method among those admitted to intensive care units for coronary artery bypass surgery. The SpO2 value was measured using finger, toe, forehead and earlobe probes and then compared with the standard value of arterial oxygen saturation (SaO2).

Pulse oximetry screening of the well newborn to assist in the diagnosis of critical congenital heart disease (CCHD) is increasingly being adopted. There are advantages to diagnosing CCHD prior to collapse, particularly if this occurs outside of the hospital setting. The current recommended approach links pulse oximetry screening with the assessment for CCHD. An alternative approach is to document the oxygen saturation as part of a routine set of vital signs in each newborn infant prior to discharge, delinking the measurement of oxygen saturation from assessment for CCHD. This approach, the way that many hospitals which contribute to the Australian New Zealand Neonatal Network (ANZNN) have introduced screening, has the potential benefits of decreasing parental anxiety and expectation, not requiring specific consent, changing the interpretation of false positives and therefore the timing of the test, and removing the pressure to perform an immediate echocardiogram if the test is positive. There are
The Importance Of Pulse Oximeter As A Medical Device. Ambulatory care is one of the most important and critical aspects of the health care field. These men and women are truly a life saver when it comes to emergency health situations that require a quick response. Many lives are saved everyday by these individuals and their role continues to grown within the health care field. One of the most important devices that has been used by ambulatory care is a pulse oximeter. A pulse oximeter is a medical device that is used to measure the pulse rate, pulse strength, as well as the blood oxygen saturation or SpO2 of individuals. The reason why this device is so needed and used by ambulatory care individuals is that it provides portability. Portability is key to emergency response because they never know exactly where and how they need to response to emergency situations. So for example say that there is an emergency fire in a downtown building. Well, in order for these individuals to be able to reach ...

The objective of this trial is to investigate the effects of protective lung ventilation on regional cerebral oxygen saturation (rSO2) during dura opening, that is from Ta (after dura opening) to Tb (before dura closing), in patients undergoing intracranial tumor surgery. This is a randomized controlled trial which will be carried out at the Second Affiliated Hospital of Soochow University. Fifty-four patients undergoing intracranial tumor surgery will be randomly allocated to the control group (C group) or the protective lung ventilation group (P group). In the C group, the tidal volume (VT) will be set at 8 ml/kg of predicted body weight, but positive end-expiratory pressure (PEEP) and recruitment maneuvers will not be used. In the P group, VT will be set at 6 ml/kg of predicted body weight combined with individualized PEEP during dura opening, while in other periods of general anesthesia, VT will be set at 8 ml/kg of predicted body weight. The level of rSO2, partial pressures of oxygen and carbon
In 1935, Karl Matthes (German physician 1905-1962) developed the first 2-wavelength ear O2 saturation meter with red and green filters (later switched to red and infrared filters). His meter was the first device to measure O2 saturation.[3]. The original oximeter was made by Glenn Allan Millikan in the 1940s.[4] In 1949 Wood added a pressure capsule to squeeze blood out of the ear so as to obtain an absolute O2 saturation value when blood was readmitted. The concept is similar to todays conventional pulse oximetry, but was difficult to implement because of unstable photocells and light sources; the method is not now used clinically. In 1964 Shaw assembled the first absolute reading ear oximeter by using eight wavelengths of light. Pulse oximetry was developed in 1972, by Takuo Aoyagi and Michio Kishi, bioengineers, at Nihon Kohden using the ratio of red to infrared light absorption of pulsating components at the measuring site. Susumu Nakajima, a surgeon, and his associates first tested the ...
The Hand Held Pulse Oximeter is ideal for use in clinics, homecare treatments, and in ambulances. Its compact and lightweight design makes non-invasive spot checks of O2 saturation of arterial hemoglobin easy.
We have shown that when it is used to monitor preterm infants receiving supplemental oxygen, the Masimo SET Radical pulse oximeter returns a reduced number of values of 87-90%. This is explained by the internal calibration algorithm, which changes in this region and adjusts SpO2 values above 87% upwards. A new software algorithm removed this artefact and returns a distribution of values that is similar to other current oximeters.. According to the product information, the oximeter is validated for accuracy in human blood studies on healthy adult volunteers in induced hypoxia studies in the range of 70-100% SpO2 against a laboratory CO-oximeter. This variation equals ±1 SD, which encompasses 68% of the population. The stated accuracy for neonates is ±3%, so by this standard at least 68% of the time the displayed SpO2 reading should be within ±3% of the simultaneous CO-oximeter value on an arterial blood sample. In this regard the original oximeter performs within all recommended accuracy ...
The AAP can play an important role in assuring the safe and effective implementation of screening for CCHD. This includes preparing members to implement screening; engaging pediatricians to participate in quality-improvement activities to ensure that newborn infants are appropriately screened with follow-up echocardiograms and specialty care, as required; partnering with public health agencies for surveillance of CCHD; and advocating for appropriate payment for all screening-related activities. In addition to promoting the implementation of pulse oximetry based screening programs, the AAP supports widespread surveillance for CCHD. Such surveillance will yield several benefits, including documentation of any improvement in detection as well as identification of areas of weakness for this comprehensive screening strategy.. Although the Secretary of HHS has recommended that screening for CCHD be added to the RUSP, it will be up to states to determine how they wish to incorporate this into their own ...

This paper describes the theory and design of a new pulse oximeter in which laser diodes and other compact laser sources are used for the measurement of oxygen saturation in patients who are at risk of developing hypoxemia. The technique depends upon illuminating special sites of the skin of the patient with radiation from modulated laser sources at selected wavelengths. The specific laser wavelengths are chosen based on the absorption characteristics of oxyhemoglobin, reduced hemoglobin and other interfering sources for obtaining more accurate measurements. The laser radiation transmitted through the tissue is detected and signal processing based on differential absorption laser spectroscopy is done in such a way to overcome the primary performance limitations of the conventionally used pulse oximetry. The new laser pulse oximeter can detect weak signals and is not affected by other light sources such as surgical lamps, phototherapy units, etc. The detailed description and operating ...
