Instructions: Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.
Input: Detection of small (10-20%) increases in lung water may be relevant to detect incipient pulmonary edema but no clinically usable method has demonstrated this capability to date.', 'In six pigs weighing 28 to 35 kg, we performed 18 determinations of extravascular lung water (EVLW; transpulmonary thermodilution method) before and immediately after the intratracheal introduction of 50 mL of saline solution. Six determinations were performed in normal lung and 12 in edematous lung.', 'In normal lung, the mean of EVLW increased from 245 +/- 18 mL to 288 +/- 19 mL (p < 0.001) after the intratracheal introduction of 50 mL of saline solution; therefore, 43 of the 50 mL (84%) were detected (range, 37-48 mL). In edematous lung, the EVLW increased from 491 +/- 106 mL to 530 +/- 108 mL after the introduction of 50 mL of saline solution; therefore, 39 of the 50 mL (77%) were detected (range, 15-67 mL).
Output:
Are small increases in extravascular lung water accurately detected by transpulmonary thermodilution?
