Oximetry, Pulse

Oximetry and Pulse are important clinical measurements that provide insights into cardiovascular and respiratory function.
Oximetry involves the non-invasive assessment of oxygen saturation in the blood, while Pulse measurements track the rhythmic expansion and contraction of arteries.
These parameters offer valuable data for diagnosing and monitoring a wide range of medical conditions, from heart disease to sleep disorders.
Researchers and clinicians rely on carefully designed protocols to accurately capture and interpret Oximetry and Pulse data, requiring a thorough understanding of the latest evidence-based approaches.
PubComapre.ai's innovative AI-driven comparison tool helps streamline this process, enabling users to quickly identify the most effective Oximetry and Pulse research protocols from the literature, preprints, and patents.
By leveraging this powerful resource, researchers can optimize their data collection and analysis, staying ahead of the curve in this critical area of medical research.

The study was approved by Institutional Review Board at Vanderbilt University Medical Center and involved two phases; Phase 1-derivation phase, followed by Phase 2-validation phase. In Phase 1, matched measurements of oxygen saturation by pulse oximetry (SpO2) and partial pressure of oxygen in arterial blood (PaO2) were obtained from 2 groups of patients: Group 1: those undergoing general anesthesia at Vanderbilt University Medical Center from 2002 to 2007 and Group 2: patients from the ARDS network -low versus high tidal volume for the Acute Respiratory Management of ARDS (ARMA) database.(8 (link)) We limited data points to those with SpO2 ≤ 98% to maximize matched data in the linear range of the sigmoidal association between SpO2 and PaO2 in the oxyhemoglobin curve, and at the same time maintain clinical relevance and adequate sample size, given that it is unlikely that patients with higher SpO2 would have PF ratios of less than 400 and thus impact the SOFA score. SF ratios corresponding to PF ratios of 100, 200, 300 and 400 were then derived. In Phase 2, the SOFA scores calculated by using these SF ratios were validated against outcomes in a 3rd group of surgical and trauma ICU patients.

Enrollment for ACTT-1 began on February 21, 2020, and ended on April 19, 2020. There were 60 trial sites and 13 subsites in the United States (45 sites), Denmark (8), the United Kingdom (5), Greece (4), Germany (3), Korea (2), Mexico (2), Spain (2), Japan (1), and Singapore (1). Eligible patients were randomly assigned in a 1:1 ratio to receive either remdesivir or placebo. Randomization was stratified by study site and disease severity at enrollment. Patients were considered to have severe disease if they required mechanical ventilation, if they required supplemental oxygen, if the oxygen saturation as measured by pulse oximetry (Spo2) was 94% or lower while they were breathing ambient air, or if they had tachypnea (respiratory rate ≥24 breaths per minute). Remdesivir was administered intravenously as a 200-mg loading dose on day 1, followed by a 100-mg maintenance dose administered daily on days 2 through 10 or until hospital discharge or death. A matching placebo was administered according to the same schedule and in the same volume as the active drug. A normal saline placebo was used at the European sites and at some non-European sites owing to a shortage of matching placebo; for these sites, the remdesivir and placebo infusions were masked with an opaque bag and tubing covers to maintain blinding. All patients received supportive care according to the standard of care for the trial site hospital. If a hospital had a written policy or guideline for use of other treatments for Covid-19, patients could receive those treatments. In the absence of a written policy or guideline, other experimental treatment or off-label use of marketed medications intended as specific treatment for Covid-19 were prohibited from day 1 through day 29 (though such medications could have been used before enrollment in this trial).
The trial protocol was approved by the institutional review board at each site (or by a centralized institutional review board as applicable) and was overseen by an independent data and safety monitoring board. Written informed consent (or consent by other institutional review board-approved process) was obtained from each patient or from the patient’s legally authorized representative if the patient was unable to provide consent. Full details of the trial design, conduct, oversight, and analyses can be found in the protocol and statistical analysis plan (available with the full text of this article at NEJM.org).

First we searched for relevant guidelines, using Medline, National Guideline Clearinghouse, Cochrane Health Technology Assessment, National Institutes of Health Consensus Development, and the US Preventative Services Task Force. On the basis of a review of those guidelines, each team developed a series of key questions. Examples of these key questions are “What is the utility of examination of urine for pyuria for the diagnosis of symptomatic urinary tract infection?” and “What is the diagnostic accuracy of pulse oximetry for nursing home pneumonia?” These key questions further guided the evidence review used to revise the existing surveillance criteria. Next, a search of the primary literature was performed, using Medline, CINAHL, Embase, Cochrane Systematic Reviews, and the Cochrane Controlled Clinical Trials Registry. Examples of key search terms include the following: nursing home, long-term care, aged, skilled nursing facility, older adults, elderly, fever, healthcare-associated infection, pneumonia, influenza, respiratory tract infection, functional impairment, confusion, leukocyte count, pulse oximetry, urinary tract infection, bacteriuria, urine culture, gastroenteritis, diarrhea, Clostridium difficile, norovirus, cellulitis, soft tissue infection, pressure ulcer, scabies. A line listing of articles that met the search criteria and were included in the final analyses is available upon request from the authors.

Infants were enrolled from February 2005 through February 2009. Permuted-block randomization was used, with stratification according to study center and gestational age (24 weeks 0 days to 25 weeks 6 days or 26 weeks 0 days to 27 weeks 6 days). Using sealed, opaque envelopes, we randomly assigned infants before birth to a target range of oxygen saturation of 85 to 89% (the lower-oxygen-saturation group) or 91 to 95% (the higher-oxygen-saturation group). Infants who were part of multiple births were randomly assigned to the same group.
Blinding was maintained with the use of electronically altered pulse oximeters (Masimo Radical Pulse Oximeter) that showed saturation levels of 88 to 92% for both targets of oxygen saturation, with a maximum variation of 3%. For example, a reading of 90% corresponded to actual levels of oxygen saturation of 87% in the group assigned to lower oxygen saturation (85 to 89%) and 93% in the group assigned to higher oxygen saturation (91 to 95%). A previous trial used a fixed 3% absolute oxygen-saturation variation throughout the entire range of saturation levels to keep caregivers unaware of study-group assignments and to separate levels of oxygen saturation in preterm infants,18 (link) but the algorithm used in the current trial differed, since the oxygen-saturation reading gradually changed and reverted to actual (non-skewed) values when it was less than 84% or higher than 96% in both treatment groups. Limits of 85% and 95% that would trigger an alarm in the delivery system were suggested, but they could be changed for individual patients.
Targeting of levels of oxygen saturation with altered pulse oximetry was initiated within the first 2 hours after birth and was continued until 36 weeks of postmenstrual age or until the infant was breathing ambient air and did not require ventilator support or CPAP for more than 72 hours, whichever occurred first. Infants who were weaned to room air but who subsequently received oxygen supplementation before 36 weeks of postmenstrual age were placed back on the assigned study pulse oximeter. The target ranges were kept unchanged from birth until 36 weeks of postmenstrual age. Adjustments in supplemental oxygen to maintain the target level of oxygen saturation between 88 and 92% were performed by the clinical staff rather than the research staff.
Data on oxygen saturation were electronically sampled every 10 seconds and downloaded by the data center. Readings of levels of oxygen saturation that were pooled (i.e., not separated according to treatment group) were provided quarterly to each center for feedback on compliance. Actual data on oxygen saturation were not provided to the clinicians or researchers but are used exclusively in this article. For the ventilation part of this trial with a 2-by-2 factorial design, participants were randomly assigned to CPAP with a protocol-driven limited ventilation strategy or to prophylactic early administration of surfactant with a protocol-driven conventional ventilation strategy.17 (link)

The outcome of interest was in-hospital mortality among children hospitalized with LRTI. As potential predictors of mortality, we considered the following classes of variables: Demographics, medical history, history of present illness, signs on physical exam, growth standards, chest radiography, and C-reactive protein levels. Information on these variables was collected by study physicians on a standardized case report form when a child was hospitalized. Subjective information on symptoms occurring prior to hospitalization was obtained from the child's caregiver at the time of hospitalization.
For this analysis, age was categorized based on IMCI categories: 6 weeks–2 months, 3–12 months, and 12–23 months. Children were considered to have low oxygen saturation if a pulse oximetry reading on room air was ≤90%. Three growth standards were also evaluated: weight for age, weight for length, and length for age, categorized based on the WHO z-scores [13] . Tables of growth standards were accessed at: http://www.who.int/childgrowth/standards/. Chest radiographs were evaluated independently by a pediatrician and a radiologist. C-reactive protein levels were categorized as >40 mg/L or ≤40 mg/L, which may indicate bacterial pneumonia [14] (link). For children with HIV infection, the clinical classification of HIV disease without CD4 count was recorded using the CDC categories – N (asymptomatic), A (mildly symptomatic), B (moderately symptomatic), C (severely symptomatic, AIDS-defining) [15] .

This was a prospective, randomized, simulation study that was conducted over 4 months, from November 2019 to February 2020, among second- to fourth-year paramedic students who had clinical practice at the Emergency Medical Center of a university-affiliated hospital. Those who voluntarily agreed to participate were included in the study. Participants were divided into 2 groups: men and women. In each group, the participants performed chest compressions on the Resusci Anne QCPR/SimPad PLUS with SkillReporter (Laerdal, Stavanger, Norway) in pairs. The total chest compression time was defined as 20 minutes assuming an in-hospital cardiac arrest scenario. In the 2-minute scenario, each participant was positioned opposite the other and performed chest compressions for 2 minutes, then took a 10-second break pretending to check the pulse and rhythm. Immediately after each chest compression, investigators measured heart rate using pulse oximetry and the degree of fatigue using questionnaires. This was repeated 5 times in 20 minutes. In the 1-minute scenario, each participant performed chest compressions for 1 minute and took a 10-second break every 2 minutes. This process was repeated 10 times in 20 minutes. After a 3-hour break, under the assumption of full recovery from fatigue, the participants in the 1-minute group crossed over to the 2-minute group and vice versa. In addition, to compare the quality of chest compressions over time, 1 set was performed for 4 minutes and 5 sets were performed in 20 minutes to compare parameters between the 2 groups. This was defined based on a minimum of 4 minutes taken for performing chest compressions by both sets of participants in the 2-minute group. All participants provided informed consent. The Institutional Review Board of the hospital reviewed and approved the specific procedures (CR-19-144).

The patients received their usual cardiac medications in the early morning on the day of surgery. Upon arriving OR, the patients were premedicated with midazolam 0.02 mg/kg and fentanyl 1 mcg/kg. A five-lead EKG, pulse oximetry, and noninvasive blood pressure monitoring were initiated. Then, we inserted a catheter into the radial artery under local anesthesia for invasive blood pressure monitoring. General anesthesia induction consisted of fentanyl 5–10 mcg/kg, midazolam 0.2–0.4 mg/kg, and pancuronium 0.1–0.15 mg/kg. Additionally, propofol 0.5–1 mg/kg was administered as appropriate. After intubation, we inserted a right internal jugular multilumen central venous catheter. Maintenance of anesthesia was with sevoflurane 1%–2%, adjusted by clinical conditions and pancuronium as needed.

All procedures were finished under general anesthesia following a standardized clinical routine. Routine monitoring of electrocardiogram, blood pressure, and pulse oximetry were carried out. General anesthesia was induced with propofol, remifentanil, and rocuronium, and the dosage of drugs depended on the body weight of the patient. The maintenance of anesthesia was implemented by the use of remifentanil and propofol, oxygen, and air (26 (link)). In accordance with the PONV prevention guidelines, we routinely provided dexamethasone and palonosetron at the end of surgery (13 (link), 27 (link)).

The study was conducted in accordance with the Declaration of Helsinki (as revised in 2013). This was a retrospective study registered as a service review and approved by the institutional review board of Guy’s and St Thomas’ NHS Foundation Trust (Approval No. LIRB: 2021/12240) and individual consent for this retrospective analysis was waived. Data were collected from the electronic patient records of all patients referred to the Lane Fox Unit (Respiratory High Dependency Unit, St Thomas’ Hospital, London, UK) and to the Sleep Disorders Centre (Guy’s Hospital, London, UK) for pre-operative screening of SDB prior to bariatric surgery (June 2014 to February 2021). The strategy employed in the pre-operative screening process has been outlined elsewhere (3 (link)). Patients referred for bariatric surgery completed a STOP-BANG questionnaire and those who scored >4 points were referred for a nocturnal pulse oximetry for two consecutive nights (3 (link)). Data collected included demographic data, sleep study data, co-morbidities, post-operative complications, maximal level of respiratory support, LOS, mortality, and the highest level of care (Appendix 1). Respiratory support data were included only if there was available documentation for the daily oxygen requirements during the whole inpatient stay. Complications are presented according to the Clavien-Dindo classification of post-operative complications. The follow up period was until discharge from hospital and these data were obtained from the electronic patient records.
All sleep data were analysed and reviewed by a sleep technician and a physician with a specialist interest in sleep who recommended the appropriate treatment. OSA was classified based on the 4% oxygen desaturation index (ODI); it was mild with an ODI of 5.0–14.9 events/hour, moderate with an ODI of 15.0–29.9 events/hour, and an ODI of 30 events/hour and above classified as severe OSA. Patients were generally offered CPAP therapy if they had moderate or severe OSA, or mild OSA with significant associated symptoms. Patients with no OSA, or mild OSA without significant symptoms were not offered CPAP therapy. The CPAP device offered was a ResMed AirSense 10 Autoset (ResMed, San Diego, California, USA) and the non-invasive ventilation (NIV) device offered was a ResMed Lumis 150 VPAP ST-A (ResMed, San Diego, California, USA).

We conducted a retrospective review of real-world data from routine care of all the patients admitted in a Level I trauma center (Centre Hospitalo-Universitaire des Hospices Civiles de Lyon, France) with severe thoracic trauma who underwent SSRF from September 2010 to January 2020. The study was conducted in accordance with the Declaration of Helsinki (as revised in 2013). The study received Institutional Review Board approval from the French Society of Thoracic and Cardio-Vascular Surgery (Société Française de Chirurgie Thoracique et Cardio-Vasculaire – IRB00012919 – 05/04/2022) and informed consent was taken from all the patients.
Severe thoracic trauma was defined by an Abbreviated Injury Scale (AIS) of 3 or more (16 (link)). All selected patients had 3 or more displaced rib fractures or flail chest [as defined per the taxonomy of Edwards et al. (17 (link))], a respiratory rate >25 cycles/min or hypoxemia on pulse oximetry (<90% without oxygen) or a circulatory failure (systolic arterial pressure <110 mmHg, or more than 30% decrease in systolic arterial pressure). On admission, full body CT scan (Figure 1) screened all patients with severe thoracic trauma without severe hemodynamic instability or life-threatening injury. Patients were managed according to the guidelines of the French society of critical care and anesthesia (18 (link)). All life threatening or hemorrhagic lesions were treated before SSRF.
