Masimo O3 Regional Oximetry Device in Pediatric Patients Undergoing Cardiac Surgery
We evaluate the relationship between the regional tissue oxygenation value (ScO2 - cerebral, StO2 - lower limb) and mixed venous saturation (SvO2) and arterial oxygen saturation (SaO2) measured before and after correction surgery in pediatric patients undergoing cardiac surgery. In addition, we compared the sCO2 and sTO2 with reference value …

Trans-abdominal Fetal Pulse Oximetry; Tissue Light Scattering and Signal Integrity
The overall purpose of this study is to evaluate maternal-fetal tissue light scattering properties. The objectives of the study are: (i) integrate established mathematical principles of oxygen saturation to model with increasing accuracy the "body in a body" problem of fetus in mother; similar to existing pulse oximeters, the calculations …

The Effects of Vertical Position on Gas Exchange in Patients With Respiratory Failure
The purpose of this study is to investigate how changing from a supine to upright position affects gas exchange for patients with hypoxemic respiratory failure. The research question is: will oxygen saturation and/or partial pressure of oxygen in the blood change when a patient with hypoxemic respiratory failure moves from …

Physiological Values When Breathing in an Air-pocket. Mountain Lab 2019 (ML2019)
The literature describes and report neurologic intact patients surviving an avalanche several hours after they were buried. The most important factor for surviving more than 15-35 min of burial is considered to be the presence of an air-filled space around the head and neck, termed an air pocket. Little is …

The Effects of Wearing a Face Mask During Exercise in Youth Hockey Players During COVID-19
There is concern that wearing a face mask during COVID will affect oxygen uptake, especially during intense exercise. COVID transmission is especially prevalent in sports such as hockey, where there is close contact between players and arena ventilation is poor. This study will assess the effect of wearing a surgical …

Treatment of Metabolic Alkalosis in Acute Exacerbations of Cystic Fibrosis
Adult cystic fibrosis (CF) patients admitted with an acute infection complicated by acid-base disturbance and decreased ventilation will be studied. They will receive salt replacement to correct the acid-base disturbance and possibly their ventilation. Assessment of symptoms (questionnaire), acid-base and electrolyte status (blood and urine tests) ventilation (overnight oxygen and …
