Pulse Oximeters

Small pulse oximeters have become widely available and can be useful for noninvasive monitoring of blood oxygen saturation by nonmedical personnel. When training control of breathing, an oximeter helps to reassure clients who hyperventilate that their oxygenation is adequate, offsetting their perception that they are not getting enough air. Low saturation may indicate a medical condition that impairs oxygen absorption. In that case, hyperventilation is a biological compensation that should not be tampered with.

ABSTRACT Objective To study the effect of nasal packing on blood oxygen saturation. Materials and methods Study was conducted on 30 patients of deviated nasal septum, who underwent septoplasty under local anesthesia followed by anterior nasal packing. The pulse oximetry was carried out three times on each patient to record the blood oxygen saturation (SpO2) by using digital pulse oximeter. The first reading of SpO2 was taken before nasal packing, second after 24 hours of nasal packing and third 3 weeks after surgery. Statistical analysis was done by Chi-square test and paired t-test. Results A total of 33.3% patients were below 20 years of age, whereas 60% were between 20 and 30 years of age and 6.7% were above 30 years. Males were 80%. It was observed that preoperative mean SpO2 was 98.3 ± 0.794%, after 24 hours of nasal packing was 97.17 ± 1.744% and 3 weeks after surgery was 98.87 ± 0.629%. On statistical analysis, the difference in SpO2 was highly significant (p < 0.001). Conclusion The application of nasal packs can be risky in old patients, more so having cardiopulmonary disease. The use of packs with airflow is recommended in these patients who should ideally be monitored with pulse oximetry.

Routine Pulse Oximetry

Abstract Introduction: Although screening for congenital heart defects (CHD) relies mainly on antenatal ultrasonography and clinical examination after birth, life-threatening cardiac malformations are often not diagnosed before the patient is discharged. Aim: To assess the use of routine pulse oximetry in the delivery room and at 24 hours postpartum, and to study its feasibility as a screening test for CHD. Material and Methods: In this prospective study, all infants born in “Cuza Voda” Maternity Hospital, Iasi, Romania, were enrolled over a thirteen-month period. Preductal oximetry was assessed during the first hour, and postductal oximetry was evaluated at twenty-four hours postpartum. Data were then analyzed to establish the sensitivity and specificity of pulse oximetry, as a screening test for CHD. Results: 5406 infants were included in the study, with a mean gestational age of 38.2 weeks and a mean birth weight of 3175 grams. During the first minute, blood oxygen saturation varied between 40% and 90% and at 24 hours of life, it ranged between 90% and 100%. Following oximetry assessment, 14 infants with critical CHD were identified. Blood oxygen saturation values in infants with CHD were lower throughout the entire period of evaluation. Pulse oximetry had good sensitivity and specificity at 1 hour (Se=87.5%, Sp=95.5%) and 24 hours (Se=92.5%, Sp=97.4%) for the diagnosis of CHD. Blood oxygen saturation values at one minute, 1 hour and 24 hours are strong discriminative parameters for the early diagnosis of CHD. Conclusion: Routine pulse oximetry during the first 24 hours postpartum represents an early indicator of CHD to facilitate timely intervention. Pulse oximetry provides excellent sensitivity and specificity and has tremendous potential as a standard screening test for CHD during the first 24 hours of life.

Snoring gets no respect.&nbsp; It also gets little to no medical therapy.&nbsp; Why is this?&nbsp; How can something that is clearly pathological based on epidemiologic research not be diagnosed and treated with effective therapy?&nbsp; The problem is the lack of a credible, objective index of pathology during snoring.&nbsp; Pulse oximetry detects drops in arterial blood oxygen saturation (SpO2) associated with obstructive sleep apnea and hypopnea events in polysomnographic (PSG) testing. &nbsp;When no desaturation is present, evidence of sleep disturbance is required to indicate the presence of pathology. &nbsp;However, obstruction at the mild end of the continuum of sleep disordered breathing (SDB) can occur without producing a drop in SpO2 or sleep disturbance; in which case it is referred to as &lsquo;primary snoring.&rsquo; Although statistically associated with co-morbidities of SDB, without there being a drop in SpO2 or sleep disturbance, primary snoring is not thought to be pathologic enough to warrant diagnosis or treatment.&nbsp; One promising means of detecting the pathological processes associated with primary snoring is molecular tissue oximetry, which detects skin tissue oxygen need, vs. oxygen supply.&nbsp;&nbsp; In cases of hypoxic challenge, regulatory mechanisms restrict blood flow to the skin to preferentially maintain blood oxygen supply to more vital organs.&nbsp; As a result, molecular tissue oximetry of the skin is a more sensitive measure of inadequate breathing than pulse oximetry measuring blood oxygen saturation.&nbsp; In this article we review molecular tissue oximetry technology and methodology and make the case that it is a promising tool for identifying pathology occurring in association with primary snoring.

Main Outcome Measure

Context:Pulse oximetry has become mobile with the use of smartphone and Bluetooth wireless technology. This technology offers many benefits but has not been extensively studied. There is a need to further validate its clinimetric properties for health professionals to provide proper guidance to patients.Objective:This investigation assessed the concurrent validity of the iSpO2pulse oximeter against a traditional pulse oximeter in measuring short-term resting blood oxygen saturation (SpO2) and pulse rate.Design:Observational study of reliability.Setting:University kinesiology laboratory.Participants:Thirty healthy, recre-ationally active adults (18 men, 12 women; mean age = 25.7 ± 5.46 years, mean height = 170.3cm ± 9.51, mean body mass = 76.4 kg ± 19.33).Intervention:Resting measurement of SpO2and pulse rate using the iSpO2pulse oximeter with the iPad Mini and a traditional pulse oximeter with Bluetooth.Main Outcome Measure:Resting SpO2and pulse rate were concurrently measured over 5 min.Results:The concurrent validity between the iSpO2and traditional pulse oximeter was moderate for measuring SpO2, intraclass correlation coeffcient (ICC)(3, 1) = .73,SEM= 0.70%, and good for pulse rate, ICC(3, 1) = .97,SEM= 1.74 beats per minute (bpm). The minimal detectable change at the 95% confidence interval for both instruments suggests that there may be 1.94% disagreement for SpO2and 4.82 bpm disagreement between pulse oximetry methods. The 95% limits of agreement (LoA) for measuring SpO2suggests that the iSpO2and traditional pulse oximeters may vary -0.28 ± 1.98%, or approximately 2%. The 95% LoA for measuring pulse rate suggests that the iSpO2and traditional pulse oximeter may vary 1.74 ± 4.98 bpm, potentially upward of 6 bpm. On the basis of the results of the LoA, it appears that there may be a slight systematic bias between the two devices, with the traditional pulse oximeter producing higher pulse rates than the iSpO2.Conclusion:The findings suggest that both instruments may be beneficial for indirect short-term measurements of resting SpO2and pulse rate.

It can be difficult to quantify progress or success when it comes to digital health, because there are many and highly varied stakeholders and perspectives to be considered, including some that are in opposition. Technological “advances” that bring clear benefits to patients, providers, and healthcare institutions are rare but do happen. In the 1980s, the first digital pulse oximeters changed the way blood oxygen saturation was monitored during surgery, an innovation that resulted in less pain for patients and better patient safety, superior real-time data for anesthetists, and greatly reduced surgical liability for hospitals. Inventions with such clear benefits to so many stakeholders remain rare three decades later. In this chapter, the evolution of digital pulse oximetry for oxygen saturation monitoring during surgical anesthesia is discussed via personal anecdote from the author.

BACKGROUND Chronic obstructive pulmonary disease (COPD) patients can suffer from low blood oxygen concentrations. Peripheral blood oxygen saturation (SpO2), as assessed by pulse oximetry, is commonly measured during the day using a spot check, or continuously during one or two nights to estimate nocturnal desaturation. Sampling at this frequency may overlook natural fluctuations in SpO2. OBJECTIVE This study used wearable finger pulse oximeters to continuously measure SpO2 during daily home routines of COPD patients and assess natural SpO2 fluctuations. METHODS A total of 20 COPD patients wore a WristOx2 pulse oximeter for 1 week to collect continuous SpO2 measurements. A SenseWear Armband simultaneously collected actigraphy measurements to provide contextual information. SpO2 time series were preprocessed and data quality was assessed afterward. Mean SpO2, SpO2 SD, and cumulative time spent with SpO2 below 90% (CT90) were calculated for every (1) day, (2) day in rest, and (3) night to assess SpO2 fluctuations. RESULTS A high percentage of valid SpO2 data (daytime: 93.27%; nocturnal: 99.31%) could be obtained during a 7-day monitoring period, except during moderate-to-vigorous physical activity (MVPA) (67.86%). Mean nocturnal SpO2 (89.9%, SD 3.4) was lower than mean daytime SpO2 in rest (92.1%, SD 2.9; P<.001). On average, SpO2 in rest ranged over 10.8% (SD 4.4) within one day. Highly varying CT90 values between different nights led to 50% (10/20) of the included patients changing categories between desaturator and nondesaturator over the course of 1 week. CONCLUSIONS Continuous SpO2 measurements with wearable finger pulse oximeters identified significant SpO2 fluctuations between and within multiple days and nights of patients with COPD. Continuous SpO2 measurements during daily home routines of patients with COPD generally had high amounts of valid data, except for motion artifacts during MVPA. The identified fluctuations can have implications for telemonitoring applications that are based on daily SpO2 spot checks. CT90 values can vary greatly from night to night in patients with a nocturnal mean SpO2 around 90%, indicating that these patients cannot be consistently categorized as desaturators or nondesaturators. We recommend using wearable sensors for continuous SpO2 measurements over longer time periods to determine the clinical relevance of the identified SpO2 fluctuations.
