This sly American painter, subject of a poker-faced, challenging retrospective at the Whitney Museum of American Art in 2012, came to prominence for his printed canvases of black stripes, licking flames and stand-alone Xs and Us, whose repetitive computer imagery was made strange through imprecise edges and wonky ink saturations.

The preferred methods for calculating hydrocarbon saturations in a geologic model incorporate an estimate of pore throat size, the densities of the fluids, and the height of the cell above the water contact, since these factors exert the strongest influence on capillary action, which ultimately controls fluid saturations.

The treatment of bradycardia is dependent on whether or not the person is stable or unstable. If oxygen saturations are low, supplemental oxygen should be provided.

In this situation, some (including NICE) recommend against its use. During acute exacerbations, many require oxygen therapy; the use of high concentrations of oxygen without taking into account a person's oxygen saturations may lead to increased levels of carbon dioxide and worsened outcomes. In those at high risk of high carbon dioxide levels, oxygen saturations of 88–92% are recommended, while for those without this risk, recommended levels are 94–98%.

Platypnea–orthodeoxia syndrome is a condition in which a person has shortness of breath and low oxygen saturations when upright (platypnea and orthodeoxia), but no symptoms when lying down. It can be caused by ventilation-perfusion mismatch, intracardiac shunting, or pulmonary shunting. In some cases, the cause is multifactorial.

Oxygen therapy should be initiated if there is significantly low blood oxygen. High flow oxygen may be harmful in those with an acute exacerbation of COPD. In the prehospital environment those given high flow O2 rather than titrating their O2 saturations to 88% to 92% had worse outcomes. Antibiotics and steroids appear useful in mild to severe disease.

Estrogen-containing medications can exacerbate LAM and are contraindicated. Agents that antagonize the effects of estrogen have not been proven to be effective for treatment, but no proper trials have been done. A trial of bronchodilators should be considered in LAM patients, because up to 17% to 25% have bronchodilator-responsive airflow obstruction. Oxygen should be administered to maintain oxyhemoglobin saturations of greater than 90% with rest, exercise and sleep.

In most conditions a saturation of 94–96% is recommended, while in those at risk of carbon dioxide retention saturations of 88–92% are preferred, and in those with carbon monoxide toxicity or cardiac arrest they should be as high as possible. Air is typically 21% oxygen by volume while oxygen therapy increases this by some amount up to 100%. The use of oxygen in medicine became common around 1917. It is on the World Health Organization's List of Essential Medicines.

It can also dry out the nose and increase the risk of fires in those who smoke. The target oxygen saturation recommended depends on the condition being treated. In most conditions a saturation of 94-98% is recommended, while in those at risk of carbon dioxide retention saturations of 88-92% are preferred, and in those with carbon monoxide toxicity or cardiac arrest the saturation should be as high as possible. The use of oxygen in medicine become common around 1917.

Chest pain is a common symptom encountered by emergency medical services. Aspirin increases survival in people with acute coronary syndrome and it is reasonable for EMS dispatchers to recommend it in people with no recent serious bleeding. Supplemental oxygen was used in the past for most people with chest pain but is not needed unless the oxygen saturations are less than 94% or there are signs of respiratory distress. Entonox is frequently used by EMS personnel in the prehospital environment.

Exploration for coal seam gas is in early stages, and targets the thick coal seams of the Permian Betts Creek Beds, with a secondary target being the Aramac Coal Measures. Coal seam gas was generated by thermogenic processes when maximum burial depths of ~2 km were achieved in the Late Cretaceous as well as secondary biogenic gas generation following uplift. The challenges to a viable gas project in the Galilee Basin include low gas saturations, distance to market and large volumes of produced water.

The vampire squid is an extreme example of a deep sea cephalopod, thought to reside at aphotic (lightless) depths from or more. Within this region of the world's oceans is a discrete habitat known as the oxygen minimum zone. Within the zone, the saturation of oxygen is too low to support aerobic metabolism in most complex organisms. Nonetheless, the vampire squid is able to live and breathe normally in the minimum zone at oxygen saturations as low as 3%, an ability that few other animals possess.

The assumption that a low mixed venous oxygen saturation (normal = 60% except for the coronary sinus where it approximates 40% reflecting the high metabolic rate of the myocardium) represents less than adequate oxygen delivery is consistent with physiological and metabolic observations. High oxygen extraction is associated with low cardiac output and decreased mixed venous oxygen saturation. Except during hypothermia and in severe sepsis, low mixed venous oxygen saturations are indication of inadequate hemodynamics. The ability of the pulmonary artery catheter to sample mixed venous blood is of great utility to manage low cardiac output states.

Supplemental oxygen is recommended in those with low oxygen levels at rest (a partial pressure of oxygen less than 50–55 mmHg or oxygen saturations of less than 88%). In this group of people, it decreases the risk of heart failure and death if used 15 hours per day and may improve people's ability to exercise. In those with normal or mildly low oxygen levels, oxygen supplementation may improve shortness of breath when given during exercise, but may not improve breathlessness during normal daily activities or affect the quality of life. A risk of fires and little benefit exist when those on oxygen continue to smoke.

Muskat, with assistance of geophysicist Milan W. Meres (1906-1963), analyzed results from the steady-state and the transient flow experiments of Ralph Dewey Wyckoff and Holbrook Gorham Botset. The experimental results showed that the flow of a mixture experienced an effective permeability that was reduced compared to the single-phase permeability. The reduced permeability correlated non-linearly with volume fraction of the other phase, and the reduction factor (or function) is denoted relative permeability. The formulation is based on Muskat's theory that the porous medium has a local structure of macroscopic size that is defined by the saturations, or volume fractions, of the fluid mixture.

Prior to correction of an ASD, an evaluation is made of the severity of the individual's pulmonary hypertension (if present at all) and whether it is reversible (closure of an ASD may be recommended for prevention purposes, to avoid such a complication in the first place. Pulmonary hypertension is not always present in adults who are diagnosed with an ASD in adulthood). If pulmonary hypertension is present, the evaluation may include a right heart catheterization. This involves placing a catheter in the venous system of the heart and measuring pressures and oxygen saturations in the superior vena cava, inferior vena cava, right atrium, right ventricle, and pulmonary artery, and in the wedge position.

The above form for Darcy's law is sometimes also called Darcy's extended law, formulated for horizontal, one-dimensional, immiscible multiphase flow in homogeneous and isotropic porous media. The interactions between the fluids are neglected, so this model assumes that the solid porous media and the other fluids form a new porous matrix through which a phase can flow, implying that the fluid-fluid interfaces remain static in steady-state flow, which is not true, but this approximation has proven useful anyway. Each of the phase saturations must be larger than the irreducible saturation, and each phase is assumed continuous within the porous medium. Based on data from special core analysis laboratory (SCAL) experiments, simplified models of relative permeability as a function of saturation (e.g.

Increased oxygen consumption during sustained exercise reduces the oxygen saturation of venous blood, which can reach less than 15% in a trained athlete; although breathing rate and blood flow increase to compensate, oxygen saturation in arterial blood can drop to 95% or less under these conditions. Oxygen saturation this low is considered dangerous in an individual at rest (for instance, during surgery under anesthesia). Sustained hypoxia (oxygenation less than 90%), is dangerous to health, and severe hypoxia (saturations less than 30%) may be rapidly fatal. A fetus, receiving oxygen via the placenta, is exposed to much lower oxygen pressures (about 21% of the level found in an adult's lungs), so fetuses produce another form of hemoglobin with a much higher affinity for oxygen (hemoglobin F) to function under these conditions.

In the hospital setting, oxygen is generally given by nasal cannula or face mask for several hours until the person is able to maintain oxygen saturations above 90% while breathing the surrounding air. In remote settings where resources are scarce and descent is not feasible, a reasonable substitute can be the use of a portable hyperbaric chamber, which simulates descent, combined with additional oxygen and medications. As with prevention, the standard medication once a climber has developed HAPE is nifedipine, although its use is best in combination with and does not substitute for descent, hyperbaric therapy, or oxygen therapy. Though they have not formally been studied for the treatment of HAPE, phosphodiesterase type 5 inhibitors such as sildenafil and tadalafil are also effective and can be considered as add-on treatment if first-line therapy is not possible; however, they may worsen the headache of mountain sickness.

The pulmonary embolism rule-out criteria (PERC) helps assess people in whom pulmonary embolism is suspected, but unlikely. Unlike the Wells score and Geneva score, which are clinical prediction rules intended to risk stratify people with suspected PE, the PERC rule is designed to rule out risk of PE in people when the physician has already stratified them into a low-risk category. People in this low risk category without any of these criteria may undergo no further testing for PE: low oxygen saturations — SaO2 <95%, unilateral leg swelling, coughing up blood, prior DVT or PE, recent surgery or trauma, age >50, hormone use, fast heart rate. The rationale behind this decision is that further testing (specifically CT angiogram of the chest) may cause more harm (from radiation exposure and contrast dye) than the risk of PE. The PERC rule has a sensitivity of 97.4% and specificity of 21.9% with a false negative rate of 1.0% (16/1666).
