The prevalence of pulmonary disease in patients with peripheral artery disease (PAD) has not been extensively studied. Recent evidence has shown that ∼20% of the patients have an atypical chest transcutaneous oxygen pressure (TcpO2) pattern during exercise, which suggests walking-induced hypoxemia. The main objectives of this study were to: (1) describe in a retrospective way the characteristics of the patients suffering from claudication, who attended a treadmill testing in our laboratory, (2) assess the prevalence of known or unknown pulmonary disease...

Polish brain death (BD) criteria established in 2007 are currently under review and therefore all reports about any problems noticed during diagnostic attempts are being carefully analyzed. According to information from intensive care units, patients with poor baseline lung function often do not tolerate ventilator disconnection during the apnea test (AT) despite previous preoxygenation and catheter O2 insufflation. Abortion of AT because of decrease of saturation as measured by pulse oximetry is quite common...

Although part of a common "blood gas" test panel with pH and pCO2, the pO2, %O2Hb, and related parameters are independently used to detect and monitor oxygen deficits from a variety of causes. Measurement of blood gases and cooximetry may be done by laboratory analyzers, point of care testing, noninvasive pulse oximetry, and transcutaneous blood gases. The specimen type and mode of monitoring oxygenation that are chosen may be based on a combination of urgency, practicality, clinical need, and therapeutic objectives...

A 52-years-old man, who had undergone coil embolization of saccular aneurysm of the brachiocephalic artery, presented with right back discomfort. Diagnosis by computed tomography was difficult because of an artifact from the coils. Angiography, on the other hand, revealed a rupture of the aneurysm, and emergency surgery was performed. A Y-shaped graft was anastomosed to the ascending aorta under partial clamp. Then, one of its branches was anastomosed to the common carotid artery also under partial clamp in an end-to-side fashion...

Circulatory management during replacement of the aortic arch is complex and involves a period of circulatory arrest to provide a bloodless field during arch vessel anastomosis. To guard against ischemic brain injury, tissue metabolic demand is reduced by systemically cooling the patient prior to circulatory arrest. Neurophysiological intraoperative monitoring (NIOM) is often used during the course of these procedures to provide contemporaneous assessment of brain status to help direct circulatory management decisions and detect brain ischemia...

INTRODUCTION: Health care demand is increasing due to greater longevity of patients with chronic comorbidities. This increasing demand is occurring in a setting of resource scarcity. To address these changes, high-value care initiatives, such as telemedicine, are valuable resource-preservation strategies. This study introduces the Roth score as a telemedicine tool that uses patient counting times to accurately risk-stratify dyspnea severity in terms of hypoxia. HYPOTHESIS: The Roth score has correlation with dyspnea severity...

Visible-light optical coherence tomography (Vis-OCT) is an emerging technology that can image hemodynamic response in microvasculature. Vis-OCT can retrieve blood oxygen saturation (sO2) mapping using intrinsic optical absorption contrast while providing high-resolution anatomical vascular structures at the same time. To improve the accuracy of Vis-OCT oximetry on vessels embedded in highly scattering medium, i.e., brain cortex, we developed and formulated a novel dual-depth sampling and normalization strategy that allowed us to minimize the detrimental effect of ubiquitous tissue scattering...
