INTRODUCTION Chronic arterial insufficiency (CAI) of lower extremities is important socio-economical and healthcare problem, due to its high incidence of morbidity, disability and mortality. OBJECTIVE The aim of our work was to determine the diagnostic importance of pulse oximetry in the early detection of stage of lower extremities CAI based on peripheral arterial oxygen saturation of haemog...

BACKGROUND Individuals residing at higher altitude may have oxygen saturation of hemoglobin different to those living at lower altitude. OBJECTIVES To find out the baseline value of SpO2 in healthy Nepali children (2-14 years) living permanently at high altitude using pulse oximeter and also to study the relation of SpO2 with age, sex and ethnicity. METHODS A descriptive observational study...

OBJECTIVE To determine if oxygen saturation measurement with pulse oximetry (SpO2) in combination with cardiotocograghy (CTG), improves the assessment of the intrapartum fetal condition. STUDY DESIGN Four expert obstetricians individually evaluated 119 cases that were monitored during labor: during the first session the CTG data were available, and in the second session CTG and SpO2 data were...

Nitric oxide (NO) has vasodilatory effects on the pulmonary vasculature in adults and animals. We examined the effects on systemic oxygenation and blood pressure of inhaling up to 80 parts per million by volume of NO at FiO2 0.9 for up to 30 minutes by 6 infants with persistent pulmonary hypertension of the newborn (PPHN). In all infants this treatment rapidly and significantly increased preduc...

INTRODUCTION Insufficient pre-oxygenation before emergency intubation, and hyperventilation after intubation are mistakes that are frequently observed in and outside the operating room, in clinical practice and in simulation exercises. Physiological parameters, as appearing on standard patient monitors, do not alert to the deleterious effects of low oxygen saturation on coronary perfusion, or t...

Cardiac related pulsatile signals can be detected in different parts of the human body, including the finger, ear lobe and forehead [1] by using near infrared (NIR) monitoring. These pulsatile signals are due to attenuation of light by the increase of arterial blood volume during systole in the cardiac cycle. Pulse oximetry exploits these pulsatile signals to calculate oxygen saturation (SpO2) ...

On the day of surgery, heart rate (HR) was 139 bpm, noninvasive blood pressure (BP) 93/31 mmHg, SpO2 81% on room air, and temperature 36.5° C. Patient was preoxygenated with 100% O2, which increased SpO2 to 99%. Anesthesia was induced by face mask with sevoflurane in oxygen with gradual increase in concentration to 6%. Immediately after venous access was obtained, propofol 2 mg/kg-1 was adminis...

INTRODUCTION Hypoxemia and high fractions of inspired oxygen (FiO2) are concerns in critically ill patients. An automated FiO2 controller based on continuous oxygen saturation (SpO2) measurement was tested. Two different SpO2-FiO2 feedback open loops, designed to react differently based on the level of hypoxemia, were compared. The results of the FiO2 controller were also compared with a histor...
