“…Serupa dengan Parameswaran, et al, Ena, et al juga menyimpulkan bahwa pulse oximetry tidak cukup sensitif sebagai metode screening PAD pada penderita diabetes melitus. 15,17 Banyak faktor yang mempengaruhi performa pulse oximetry antara lain penggunaan pewarna kuku, kuku buatan, ekstremitas yang dingin atau penderita dengan sirkulasi ekstremitas yang sudah terlalu jelek, penderita dengan kulit gelap, dan pada saturasi oksigen yang terlalu rendah (di bawah 80%). 18,19 Keseluruhan faktor tersebut mengarahkan pada hasil rendah palsu, kecuali penggunaan pewarna kuku, tetapi pada penelitian kali ini justru semua ketidaksesuaian pulse oximetry dengan APSV menunjukkan hasil perbedaan saturasi oksigen yang normal.…”

Background: Diabetes Mellitus is the most common complication of vascular complications, one of which is peripheral arterial disease (PAD), which can increase morbidity and mortality in diabetic patient.Early screening parameter and diagnosis of PAD that currently still largely accepted are Ankle-Brachial Index (ABI) and pulse oximetry. ABI and pulse oximetry each has advantages and disadvantages. Patients with diabetes, especially if accompanied by abdominal obesity often have arterial sti?ness so that the value of ABI actually increased, in this case pulse oximetry has a higher sensitivity. Ankle Peak Systolic Velocity (APSV) which is the average of Peak Systolic Velocity (PSV) of anterior and posterior tibial artery at ankle joint level is a new parameter for assessing ischemia of the lower limb and is not in?uenced by arterial sti?ness. The purpose of this study was to determine and analyze the correlation between ankle-brachial index, pulse oximetry and ankle peak systolic velocity in DM patients without abdominal obesity.Materials and methods: This study was observational analytic with cross-sectional design study in subjects with DM without abdominal obesity who meet the inclusion and exclusion criteria.Results: The subjects consisted of 38 limbs from 19 people, 11 (57.9%) males and 8 (42.1%) women aged 47-68 years. Spearman test showed a positive correlation was signifcant between ABI with APSV (r = 0.549, p <0.001). Correlation between ABI and pulse oximetry; pulse oximetry and APSV showed weak signifcant negative correlation (r = -0.347, p <0.05 and r = -0.369, p <0.05). Only APSV which has a strong positive correlation with clinical PAD signifcantly (r = 0.743, p <0.001).Conclusions: There is no strong correlation between ABI, pulse oximetry and APSV in DM patients without abdominal obesity. APSV can replace ABI and pulse oximetry as a non-invasive examination of diabetic patients for screening and follow-up PAD

“…Although Doppler ultrasound meets all these requirements, it only maps blood flow, which is operator dependent and influenced by motion artifacts, resulting in limited sensitivity and specificity to detect the disease in its early stage [ 4 ]. A POC technique that provides direct label-free molecular and functional information of vasculature is needed to reliably detect and monitor vascular diseases [ 5 , 6 ].…”

Vascular diseases are becoming an epidemic with an increasing aging population and increases in obesity and type II diabetes. Point-of-care (POC) diagnosis and monitoring of vascular diseases is an unmet medical need. Photoacoustic imaging (PAI) provides label-free multiparametric information of deep vasculature based on strong absorption of light photons by hemoglobin molecules. However, conventional PAI systems use bulky nanosecond lasers which hinders POC applications. Recently, light-emitting diodes (LEDs) have emerged as cost-effective and portable optical sources for the PAI of living subjects. However, state-of-art LED arrays carry significantly lower optical energy (<0.5 mJ/pulse) and high pulse repetition frequencies (PRFs) (4 KHz) compared to the high-power laser sources (100 mJ/pulse) with low PRFs of 10 Hz. Given these tradeoffs between portability, cost, optical energy and frame rate, this work systematically studies the deep tissue PAI performance of LED and laser illuminations to help select a suitable source for a given biomedical application. To draw a fair comparison, we developed a fiberoptic array that delivers laser illumination similar to the LED array and uses the same ultrasound transducer and data acquisition platform for PAI with these two illuminations. Several controlled studies on tissue phantoms demonstrated that portable LED arrays with high frame averaging show higher signal-to-noise ratios (SNRs) of up to 30 mm depth, and the high-energy laser source was found to be more effective for imaging depths greater than 30 mm at similar frame rates. Label-free in vivo imaging of human hand vasculature studies further confirmed that the vascular contrast from LED-PAI is similar to laser-PAI for up to 2 cm depths. Therefore, LED-PAI systems have strong potential to be a mobile health care technology for diagnosing vascular diseases such as peripheral arterial disease and stroke in POC and resource poor settings.

“…In the literature, the ABI relationship and a SpO 2 variation of 2% -5% have been suggested as an effective additional method for screening patients with PAD [9][10][11]. This relationship remains unclear considering the interacting factors [12][13]. Our aim was to assess the correlation between pulse oximetry and ABI in an academic referral hospital setting.…”
