Anaesthesiology Critical Care MCQs- 5th Year PMU

Most of the body water content is located within the extracellular compartment

Water content in a newborn child is 80-60% of its body weight

Plasma water content is only 5% of the body weight

Total body water content in adult females is 60% of their body weight

Tissue hypoxia with hyperlactatemia

Kidney failure

Metabolic intoxication

Diarrhoea

Bilateral opacities consistent with pulmonary edema on chest radiography Or computed tomography scan that are not fully explained by pleural effusions, lobar/lung collapse, pulmonary nodules or heart failure are required for the diagnosis

Several conditions can lead to the development of ARDS, including aspiration of gastric contents, pneumonia, sepsis (most common cause), trauma, transfusion of blood products (particularly plasma-rich products), pancreatitis, fat emboli, and drowning

Most patients with ARDS require intubation and mechanical ventilation with low tidal volumes (6 mL/kg predicted weight) and targeted plateau pressures of equal to or less than 30 cm H20

Moderate to severe impairment of oxygenation is defined by the ratio of arterial oxygen tension to fraction of inspired oxygen (PaO2/FiO2). In Severe ARDS PaO2/FiO2 is between 200 and 300 mmHg on PEEP >5 cm H2O
