Adult diagnosis is based on a PaO 2 /FiO 2 ratio (ratio of partial pressure arterial oxygen and fraction of inspired oxygen) of less than 300 mm Hg despite a positive end-expiratory pressure (PEEP) of more than 5 cm H 2 O. [1] Cardiogenic pulmonary edema, as the cause, must be excluded. [4]
The total value produced by the economy is the sum of the values-added by every industry. The expenditure method is based on the idea that all products are bought by somebody or some organisation. Therefore, we sum up the total amount of money people and organisations spend in buying things. This amount must equal the value of everything produced.
IRDS affects about 1% of newborns and is the leading cause of morbidity and mortality in preterm infants. [5] Data have shown the choice of elective caesarean sections to strikingly increase the incidence of respiratory distress in term infants; dating back to 1995, the UK first documented 2,000 annual caesarean section births requiring ...
In fluid dynamics, the Hagen–Poiseuille equation is a physical law that gives the pressure drop in a fluid flowing through a long cylindrical pipe. The assumptions of the equation are that the flow is laminar viscous and incompressible and the flow is through a constant circular cross-section that is substantially longer than its diameter.
The primary cause triggers an uncontrolled inflammatory response. [citation needed] Sepsis is the most common cause of multiple organ dysfunction syndrome and may result in septic shock. In the absence of infection, a sepsis-like disorder is termed systemic inflammatory response syndrome (SIRS). Both SIRS and sepsis could ultimately progress to ...
In economics, distribution is the way total output, income, or wealth is distributed among individuals or among the factors of production (such as labour, land, and capital). [1] In general theory and in for example the U.S. National Income and Product Accounts , each unit of output corresponds to a unit of income.
It is possible for trauma to cause clotting problems even without resuscitation efforts. [3] Damage control resuscitation is based on three principles: permissive hypotension: tries to balance temporary suboptimal perfusion to organs with conditions for halting blood loss by setting a goal of 90 mmHg systolic blood pressure [3]
[2] [3] The law of diminishing returns does not cause a decrease in overall production capabilities, rather it defines a point on a production curve whereby producing an additional unit of output will result in a loss and is known as negative returns. Under diminishing returns, output remains positive, but productivity and efficiency decrease.
