Decremental PEEP titration: a step away from the table.
The setting of PEEP in patients with ARDS has become a standard of practice for nearly 46 years.1 One of the more widely used methods in current practice for PEEP selection is the ARDS Network PEEP/FIO2 table. 2 This table guides the clinician to increase or decrease PEEP and FIO2 based on oxygenation. The low-to-modest levels of PEEP utilized throughout the table have been challenged in 2 stud...
متن کاملA Coulometric-Titration Coulometer
A highly precise coulometer is described which permits time integration of currents totaling 100 coulombs or more with a precision of about 1 part in 100,000. The current to be integrated oxidizes hydroquinone in an electrolysis cell, producing quinone and acid. The quinone is t hen reduced by constant-current coulometric titration, the end point being indicated by hydrogen-ion concentration me...
متن کاملA Student-Designed Potentiometric Titration: Quantitative Determination of Iron(II) by Caro's Acid Titration
Oxidation–reduction titrations and potentiometric methods provide a convenient experimental means to quantitatively determine compositions of unknown mixtures containing oxidizable/reducible species. Over the past decade, numerous titration methods have appeared in this Journal (1–6) and in standard laboratory manuals (7–10) involving common titrants such as potassium dichromate, iodine, potass...
متن کاملBone CO2-titration curves in acute hypercapnia obtained with a modified titration technique.
Bone CO2-titration curves were obtained in mature rats weighing 500-600 g. Animals were exposed for one hour to 1, 3, 5, 10, or 15% CO2 in air. Measurements of bone CO2, were made using a modified titrimetric analysis on fresh and oven-dried samples of paired rat femurs. A manometric method was used for comparison. Arterial blood samples were obtained for measurements of partial pressure of CO2...
