Capillary refill time (CRT) is a non-invasive technique to evaluate tissue perfusion, and quantitative CRT (Q-CRT) adapted to pulse oximetry was developed with patients with sepsis and compared to blood lactate and sepsis scores. In post liver transplantation, large amounts of fluid administration are necessary for maintaining tissue perfusion to grafted liver against intravascular hypovolemia.

The main mechanism of body temperature decrease during cesarean delivery under spinal anesthesia is core-to-peripheral redistribution of body heat, attributable to vasodilation. Perfusion index (PI) obtained with a pulse oximeter helps to assess peripheral perfusion dynamics by detecting the change in peripheral vascular tone.

Oxygen saturation has been shown in risk score models to predict mortality in emergency medicine. The aim of this study was to determine whether low oxygen saturation measured by a single-point measurement by pulse oximetry (SpO2) is associated with increased mortality in the general adult population.

Pulse oximetry is widely used in the clinical setting. The purpose of this validation study was to investigate the level of agreement between oxygen saturations measured by pulse oximeter (SpO2) and arterial blood gas (SaO2) in a range of oximeters in clinical use in Australia and New Zealand.

A double chain-sprocket winnower was developed to reduce the hand drudgery and increase the efficiency of the winnower. The winnower consisted of two stage chain and sprocket transmission system with an overall speed increment ratio of 6. The performance and ergonomical evaluation of the developed winnower was carried out using anemometer and pulse oximeter, respectively. Both the evaluation parameters were compared with the pinion driven winnower and single chain-sprocket type winnower.

Peripheral cyanosis is common in children at any age and is not important. Central cyanosis is always important but may be missed in a child with severe anaemia or children with pigmented skin. It is detected by looking at the colour of the tongue – blue colouration suggests a saturation of less than 85%. Central cyanosis is not improved by breathing 100% oxygen and its presence should be confirmed by a pulse oximeter. Long standing cyanosis may be associated with ‘clubbing’ of the nails of the hands and feet.
