Background: One of the most important methods of complementary medicine is music and phonotherapy and one of the most beautiful sounds is the sound from the recitation of the Quran. We aimed to investigate the effect of the sound of the Quran on physiological responses in preterm infants. Materials and Methods: <...

BACKGROUND Pre-hospital, high-concentration oxygen therapy during acute exacerbation of chronic obstructive pulmonary disease (AECOPD) has been associated with increased mortality. Recent COPD guidelines have encouraged titrated oxygen therapy with a target saturation range of 88-92%. Oxygen therapy leading to saturation above 92% is defined as 'inappropriate oxygen therapy'. OBJECTIVES To ex...

conclusions our case highlights the fact that the tip of the pulmonary artery catheter can easily advance into a peripheral branch of the pulmonary artery and cause pulmonary venous blood to be sampled instead of pulmonary arterial blood. a variety of monitoring techniques are needed to confirm accurate catheter placement. background pressure and waveform at the catheter tip are continuously mo...

Pulse oximeters are used to noninvasively measure oxygen saturation in arterial blood (SaO2). Although arterial oxygen saturation measured by pulse oximeter (SpO2) is usually indicated in 1% increments, the value of SaO2 from arterial blood gas analysis is not an integer. We have developed a new pulse oximeter that can measure SpO2 to one digit after the decimal point. The values of SpO2 from t...

The delivery of oxygen by arterial blood to the tissues of the body has a number of critical determinants including blood oxygen concentration (content), saturation (S O2 ) and partial pressure, haemoglobin concentration and cardiac output, including its distribution. The haemoglobin-oxygen dissociation curve, a graphical representation of the relationship between oxygen satur-ation and oxygen ...
