Ventilation Performance

Background During the past few years, many manufacturers have introduced new modes of ventilation in anesthesia ventilators, especially partial-pressure modalities. The current bench test study was designed to compare triggering and pressurization of five new anesthesia ventilators with four intensive care unit ventilators. Methods Ventilators were connected to a two-compartment lung model. One compartment was driven by an intensive care unit ventilator to mimic "patient" inspiratory effort, whereas the other was connected to the tested ventilator. The settings of ventilators were positive end-expiratory pressures of 0 and 5 cm H2O, and pressure-support ventilation levels of 10, 15, and 20 cm H2O with normal and high "patient" inspiratory effort. For the anesthesia ventilators, all the measurements were obtained for a low (1 l/min) and a high (10 l/min) fresh gas flow. Triggering delay, triggering workload, and pressurization at 300 and 500 ms were analyzed. Results For the five tested anesthesia ventilators, the pressure-support ventilation modality functioned correctly. For inspiratory triggering, the three most recent anesthesia machines (Fabius, Drägerwerk AG, Lübeck, Germany; Primus, Drägerwerk AG; and Avance, GE-Datex-Ohemda, Munchen, Germany) had a triggering delay of less than 100 ms, which is considered clinically satisfactory and is comparable to intensive care unit machines. The use of positive end-expiratory pressure modified the quality of delivered pressure support for two anesthesia ventilators (Kion, Siemens AG, Munich, Germany; and Felix, Taema, Antony, France). Three of the five anesthesia ventilators exhibited pressure-support ventilation performance characteristics comparable to those of the intensive care unit machines. Increasing fresh gas flow (1 to 10 l/min) in the internal circuit did not influence the pressure-support ventilation performance of the anesthesia ventilators. Conclusion Regarding trigger sensitivity and the system's ability to meet inspiratory flow during pressure-supported breaths, the most recent anesthesia ventilators have comparable performances of recent-generation intensive care unit ventilators.

Mechanical ventilation (MV) is among the main basics of supportive treatment for respiratory failure in the intensive care unit (ICU). This supportive treatment may cause undesirable complications that led to the introduction of various MV modes. The current study was aimed to assess and compare outcomes of volume support ventilation (VSV) and pressure support ventilation (PSV) regarding spontaneous breath return, weaning and hemodynamic changes among patients admitted at ICU following surgical procedures. This single-blinded randomized-clinical-trial (RCT) was conducted on 100 patients admitted at ICU in 2018-2019. Patients were randomly divided into two fifty-member groups treated with PSV and VSV modes. Oxygen saturation, systolic (SBP) and diastolic blood pressure (DBP), mean arterial pressure (MAP), arterial blood gas (ABG), extubation and MV time and sedation based on RAMSY criteria were recorded and compared. Mean age (P=0.79) and gender distribution (P=0.57) were not statistically different in the two groups. Time has no effect on patients' hemodynamic (P>0.05) while hemodynamic stability was superior in VSV (P<0.05). ABG showed no statistical difference between groups (P>0.05) except for arterial oxygen pressure that was higher in the VSV group (P<0.001). The duration of MV, extubation time and duration of ICU admission was significantly lower in the VSV group. Furthermore, sedation based on RAMSY criteria showed the superiority of VSV (P<0.05). Use of VSV mode was accompanied with superior outcomes in four entities including earlier and easier weaning, shorter duration of ICU admission, least hemodynamic instabilities and least sedation requirement in comparison to PSV mode. © 2019 Tehran University of Medical Sciences.
