Words similar to pressure-volume
Example sentences for: pressure-volume
How can you use “pressure-volume” in a sentence? Here are some example sentences to help you improve your vocabulary:
Because of the difficulties associated with measurement of pressure-volume curves, incremental titration of PEEP in an attempt to find the 'best' PEEP, based on improvement in oxygenation, is common practice in the management of hypoxaemic respiratory failure.
Iron is necessary in the synthesis of collagen [ 39 ] , and collagen content has been shown to be reduced in iron deficient hearts [ 40 ] . If this is similarly true for arteries in iron deficient animals, a significant increase in distensibility would result, altering the normal pressure-volume relationship.
Third, PEEP opt in the study (approximately 11 cmH 2 O) was lower than levels reported in other ARDS studies [ 20 ] . Higher tidal volume (10 ml/kg) leading to higher mean airway pressure, the termination criteria used in our study, and the differences in titration technique (based on oxygenation versus pressure-volume curve) may account for this difference.
Whereas Kiefer and colleagues used pressure-volume curves for PEEP titration, we titrated PEEP on the basis of improvement in oxygenation, which is a commonly used method in clinical practice because determination of pressure-volume curves can sometimes be cumbersome.
Similarly, in humans without ALI or ARDS, PEEP reduces splanchnic oxygenation and this is accompanied by decreases in cardiac output, albeit with no change in lactate levels [ 14 ] . Recently, Kiefer and colleagues [ 9 ] reported no change in splanchnic perfusion when PEEP was titrated on the linear portion of the pressure-volume curve in patients with ALI [ 9 ] .
