“…In PSV mode, comparisons with ICU or anesthesia ventilators, 2,13,14,23 home-care ventilators, 8,24 mid-level ICU ventilators, 25 and older-generation transport ventilators 2 show that all the turbine ventilators tested in this study had performance comparable to ICU ventilators. In the dynamic conditions, several ventilators were comparable to ICU or home-care ventilators, and had better performance than older-generation ICU ventilators.…”

“…The gas-powered ventilators had relatively long triggering delay and poor pressure sensitivity. The turbine ventilators had more sensitive triggering, comparable to ventilators designed for home care 8 and ICU use. 13,14 The Monnal T60 showed auto-triggering at the highest triggering sensitivity setting in a first study, but that was corrected by new software.…”

Evaluation of Ventilators Used During Transport of Critically Ill Patients: A Bench Study

OBJECTIVE: To evaluate the most recent transport ventilators' operational performance regarding volume delivery in controlled mode, trigger function, and the quality of pressurization in pressure support mode. METHODS: Eight recent transport ventilators were included in a bench study in order to evaluate their accuracy to deliver a set tidal volume under normal resistance and compliance conditions, ARDS conditions, and obstructive conditions. The performance of the triggering system was assessed by the measure of the decrease in pressure and the time delay required to open the inspiratory valve. The quality of pressurization was obtained by computing the integral of the pressure-time curve for the first 300 ms and 500 ms after the onset of inspiration. RESULTS: For the targeted tidal volumes of 300, 500, and 800 mL the errors ranged from -3% to 48%, -7% to 18%, and -5% to 25% in the normal conditions, -4% to 27%, -2% to 35%, and -3% to 35% in the ARDS conditions, and ؊4% to 53%, ؊6% to 30%, and ؊30% to 28% in the obstructive conditions. In pressure support mode the pressure drop range was 0.4 -1.7 cm H 2 O, the trigger delay range was 68 -198 ms, and the pressurization performance (percent of ideal pressurization, as measured by pressure-time product at 300 ms and 500 ms) ranges were -9% to 44% at 300 ms and 6%-66% at 500 ms (P < .01). CONCLUSIONS: There were important differences in the performance of the tested ventilators. The most recent turbine ventilators outperformed the pneumatic ventilators. The best performers among the turbine ventilators proved comparable to modern ICU ventilators.

“…From the standpoint of high responsiveness to the patient's flow demand, ''constant-revolution blower systems'' with a proportional valve perform very well. However, although in the past these systems had a clear responsiveness advantage over ''dynamic blower systems'', recent developments show that dynamic blowers with a small blower wheel diameter and a very high revolution rate per minute are also extremely responsive to patient demand [7,8].…”

“…Calderini et al 56 reported that, in the presence of leaks, time-cycled PCV provided better synchrony and patient comfort than flow-cycled PSV during NIV. Battisti et al 57 reported delayed cycling in the presence of leaks with bi-level ventilators. Borel et al, 36 however, found that expiratory cycling was not affected by the level of intentional leaks in masks, except with COPD conditions.…”

There is arguably more evidence to support the use of noninvasive ventilation (NIV) than any other practice related to the care of patients with acute respiratory failure. Despite this strong evidence base, NIV seems to be under-utilized and the failure rate (need for intubation) may be as high as 40%. Some of these failures potentially relate to asynchrony, although the relationship between asynchrony and NIV failure has not been well studied. Good NIV tolerance has been associated with success of NIV, and improved comfort has been associated with better synchrony. In one study a high rate of asynchrony occurred in 43% of patients during NIV. Asynchrony is commonly associated with leaks. Thus, reducing the leak related to the interface and using a ventilator with good leak compensation should reduce the rate of asynchrony. Asynchronies can also be related to the underlying disease process. This paper reviews issues related to asynchrony during NIV and suggests strategies that might be used to correct asynchrony when it occurs.
