Maximum respiratory rate at day 1 and SOFA score >7 at day 1 were higher in NIV.
For TTN group, significant correlation was found between plasma DLIS levels and maximum respiratory rate, duration of tachypnea, and length of hospitalization on the 1st day.
Together, these effects can inhibit substrate supply and cause the uncoupled rate to be lower than the true maximum respiratory rate.
In fact, the respiratory data indicate that mitochondria from Q111 cells are capable of higher spare respiratory capacity and higher maximum respiratory rate than their 'WT' counterparts in the absence of ZDON.
For intact cells, the best assay is the equivalent measurement of cell respiratory control, which reports the rate of ATP production, the proton leak rate, the coupling efficiency, the maximum respiratory rate, the respiratory control ratio and the spare respiratory capacity.
For this reason CCCP might have different oxidation rates in different breast cancer cells and thus potentially contribute to the differences in the maximum respiratory rates observed to some degree.
These factors are apparent in synaptosomes, where addition of pyruvate to circumvent limited glycolytic flux in the presence of uncoupler strongly increases 'maximum' respiratory rate [ 66].
Maximum Vt, maximum IPAP, EVT, Vmin, leaks, respiratory rate, heart rate, systolic blood pressure, diastolic blood pressure, and IPAP were measured upon hospitalization, after 1 hour, 3 hours, and 12 hours, and then every 24 hours during NIV.
ALI, acute lung injury; ARDS, acute respiratory distress syndrome; PaCO2, partial pressure of arterial carbon dioxide; Pmax, maximum airway pressure; RR, respiratory rate; VT, tidal volume.
Despite attempts to normalize partial carbon dioxide tension (PCO2) with increases in respiratory rate (maximum rate allowed by protocol was 35 breaths/min), hypercapnia in the low Vt/high PEEP group was substantial, resulting in significant respiratory acidosis at all time points compared with the high Vt/low PEEP group.
ALI = acute lung injury; ARDS = acute respiratory distress syndrome; FiO2 = fractional inspired oxygen; ICU = intensive care unit; LP = lung protective; MV = mechanical ventilation; PaO2 = arterial oxygen tension; PBW = predicted body weight; Pmax = maximum airway pressure; RR = respiratory rate; SEDIC = Sedation Intensive Care VTT = tidal volume.
