Increasing the depth of sedation decreased minute ventilation
and Ti/TT, but the only differences that achieved statistical significance were those between Ramsay 2 and both Ramsay 4 and 3 ( P < 0.
During the study the minute ventilation
, VE is graphed on the Y axis and PC[O.
technology, called the ExSpiron Patient Monitor, to measure minute ventilation
The usual initial settings were 100% minute ventilation
using the patient's ideal body weight, PEEP within the range of 2-12 cm [H.
(VE) increased similarly across Test Minute between the Study Visits.
Technical considerations related to the minute ventilation
/ carbon dioxide output slope in patients with heart failure.
This stability is achieved by the exquisite sensitivity of the chemoreceptor system, typically assessed by measuring the change in minute ventilation
as a patient rebreathes C[O.
Results--Respiratory rate was higher, tidal volume lower, and minute ventilation
not different in lateral versus dorsal recumbency.
The technical term for the movement of air into and out of the lungs is minute ventilation
(Ve), and it is measured in liters per minute (l/min).
Factors behind the increased vulnerability include their small mass for a given dose of food or water contamination, increased transdermal absorption due to thinner skin and increased surface-area-to-mass ratio, more hand-to-mouth activity, more time spent on the ground, higher relative minute ventilation
, and a longer window of exposure due to their longer life expectancy compared with adults, said Dr.
2010), we found that both the ventilation rate and the tidal volume were increased and that minute ventilation
2]O decreased minute ventilation
during exercise and had a tendency to decrease respiratory rate.
As a consequence of these changes a small fall in minute ventilation
of around 10 per cent occurs in normal subjects from wakefulness to non-rapid eye movement (NREM) sleep, resulting in a small rise in PaC[O.
While the respiratory rate and vital capacity [do] not change in pregnancy, there is an increase in tidal volume, minute ventilation
(40%), and minute oxygen uptake (20%) with resultant decrease in functional residual capacity and residual volume of air as a consequence of the elevated diaphragm .
By increasing the minute ventilation
(whether with an increase in frequency or respiratory rate) one will only further load the right ventricle (and limit the cardiac output with the predicted effect on mixed venous saturation).
