In aquatic environments, oxygen saturation is a relative measure of the amount of oxygen (O 2) dissolved in the water. Hemoglobin the colored substance in blood is a carrier of oxygen. The oxygen saturation of haemoglobin in arterial blood - which is a measure of the average amount of oxygen bound to each haemoglobin molecule. 1. Candona subtriangulata has the highest minimum oxygen requirement of 5.6 mg/L. Oxygen capacity is the maximal amount of oxygen that can be bound to hemoglobin. Oxygen is a critical nutrient and the body can die within six minutes without it. Any level below 88 per cent is dangerous and incapacitating to your body. If the oxygen level is below this, it can be an indicator that there is a lung problem. A pulse oximeter can measure oxygen saturation. Normal arterial blood oxygen levels as measured by an arterial blood gas range from 75 to 100 millimeters of mercury (mm Hg), which is a measurement of the amount of oxygen that is dissolved in the arterial blood. In the blood, hemoglobin binds free oxygen rapidly to form oxyhemoglobin leaving only a small percentage of free oxygen dissolved in the plasma. The Oxygen-Hemoglobin Dissociation Curve shows the percent of oxygen binding to Hgb per mmHg. Automatic compensation of T°C, atmospheric pressure and salinity. The The percentage saturation is given as a digital readout together with an audible signal varying in pitch depending on the oxygen saturation. Blood oxygen levels below 90% are considered low (hypoxemia). Pulse Oximeter Readings Normal Range The Dissolved Oxygen readings are automatically compensated for the temperature effects on the oxygen solubility and membrane permeability. Modern techniques involve either an electrochemical or optical sensor. These subtle, but important differences, are described in the following section.
