AI Article Synopsis
- The study aimed to determine the effectiveness of a finger-mounted tissue oximeter in assessing blood flow in patients with peripheral arterial disease (PAD).
- Researchers measured several indicators, including ankle-brachial index (ABI), transcutaneous oxygen pressure (TcPO), and skin perfusion pressure (SPP) in 72 PAD patients and found significant correlations between tissue oxygenation saturation (rSO) and these measurements.
- Results indicated that rSO was significantly lower in more severe PAD groups compared to less severe ones, highlighting that the finger-mounted tissue oximeter is a quick, simple, and painless method for evaluating limb circulation in PAD patients.
Article Abstract
: To investigate whether a finger-mounted tissue oximeter is useful in evaluating limb blood flow in patients with peripheral arterial disease (PAD). : Seventy-two patients with PAD were included, and the ankle-brachial index (ABI), transcutaneous oxygen pressure (TcPO), and skin perfusion pressure (SPP) were measured. The regional tissue oxygenation saturation (rSO) was measured using a finger-mounted tissue oximeter at the ankle, dorsal foot, and each dorsal and plantar toe. Correlations between rSO and ABI and between TcPO and SPP were analyzed. The patients were divided into three groups: Fontaine IIa (F-IIa), IIb (F-IIb), and III and IV (F-III/IV) groups. The difference in rSO between each group was analyzed. : Significant correlations were observed between rSO and TcPO and between rSO and SPP. TcPO and SPP in the F-III/IV group were significantly lower than those in the F-IIa group. rSO in the F-IIb and F-III/IV groups was significantly lower than that in the F-IIa group. : The measurement of rSO using finger-mounted tissue oximetry is quick, simple, and painless. It can be used on any skin area and is useful to evaluate limb circulation in patients with PAD.

Article Synopsis
- The research involved 78 pregnant women undergoing cesarean sections, measuring fetal and neonatal StO levels immediately before and after birth, mainly focusing on the first 5 minutes post-delivery.
- Results indicated a possible trend where neonates diagnosed with respiratory disorders had lower StO levels compared to those without, although the findings did not reach statistical significance.

: To determine the prognostic value of regional tissue oxygenation saturation (rSO) for ulcer healing after endovascular treatment (EVT) of peripheral arterial disease (PAD). : Among PAD patients, 34 patients with chronic limb-threatening ischemia underwent EVT for limb salvage. We retrospectively analyzed the cutoff rSO values on postoperative day 1 to predict ulcer healing and patient prognosis.

Purpose: To investigate the utility of the device for evaluating intestinal oxygenation and viability using an animal model.
Methods: Sprague-Dawley rats underwent laparotomy under general anesthesia, and the blood vessels in the terminal ileum were clamped to create ischemia. We measured the regional tissue oxygenation saturation (rSO) using an oximeter after 1, 3, and 6 h of vessel clamping.

Unlabelled: The Consensus on Resuscitation Science and Treatment Recommendations indicate the target SpO2 values during the first 10 min of life. There are a few studies of values of brain regional saturation of oxygen (rSO2) in newborns, conventional instruments are large and not suitable for measuring in the delivery room. The purpose of this study was to develop reference values for brain rSO2 up to 10 min after birth and to review the changes in cerebral oxygenation in late preterm and term newborn infants immediately after birth.

We conducted a single-center cross-sectional study to determine whether scrotal-testicular tissue oxygen saturation (S-T StO) measured by finger-mounted near-infrared spectroscopy is useful for the evaluation of testicular function. S-T StO was significantly higher in patients with nonobstructive azoospermia (NOA, p< 0.05), and showed a positive correlation with luteinizing hormone levels (LH) even in participants without NOA (r = 0.
