Comparison of Bilevel Ventilators with System Leaks

Seven bilevel ventilators were compared using the lung simulator with system leaks: Vision and Synchrony (Respironics; Murrysville, PA, USA); VENTImotion (Weinmann; Hamburg, Germany); VPAP III ST-A (ResMed; North Ryde, Australia); Flexo ST 30 (Curative Medical Inc, Santa Clara, CA, USA); Vivo 30 (Breas Medical AB; Mölnlycke, Sweden) and SmartAir Plus (Airox; Pau, France) (Table 1). Each ventilator evaluated was connected to the lung simulator by a standard disposable corrugated circuit (length, 2.0 m). All the ventilators were studied with a dry circuit; humidifiers and heat and moisture exchangers were removed.
All the ventilators were set in PSV mode as follows: positive end-expiratory pressure (PEEP), 5 cm H₂O; pressure support level, 15 cmH₂O; back-up respiratory rate, 10 breaths/min; maximal duration of the inspiratory phase, 1.5 s. The trigger sensitivity was set to be as sensitive as possible while avoiding auto-triggering. The inspiratory rise time was set to 100 ms, or the most rapid setting (90 ms for the VPAP III ST-A ventilator). The inspiratory termination criteria, when adjustable, were set to the most sensitive level. During data collection, trigger sensitivity and inspiratory effort were adjusted as leaks were introduced into the system, to avoid simulator-ventilator asynchrony (auto-triggering or back-up ventilation).

Bilevel NPPV Protocol for Respiratory Support

Check if the same lab product or an alternative is used in the 5 most similar protocols

Bilevel NPPV was delivered via nasal or oronasal mask using one of the following ventilators: (1) VPAP ST series (VPAP II ST, VPAP II ST-A, or VPAP III ST-A; ResMed, Sydney, Australia), (2) VS SERENA (Res Med, Sydney, Australia), or (3) BiPAP Synchrony series (BiPAP Synchrony or BiPAP Harmony; Respironics, Inc., Murrysville, PA). The commercial masks were sized appropriately to each patient's nose or face. In all cases, the ventilator was initially set to spontaneous/timed (S/T) mode. We start NPPV with low inspiratory pressures (8–10 cm H₂O) and gradually titrate upward as tolerated by the patient as previously reported[1 (link)] with an EPAP in the range of 2–5 cm H₂O, with a backup respiratory frequency (f_R) below the rate of awake spontaneous breathing. We did not set up any target minute ventilation or tidal volume on the initiation of NPPV. Oxygen was supplied from the mask's side port at a flow rate needed to achieve a target SpO₂ of 90%. Heated humidifiers were used for all patients.

Elective Initiation of Noninvasive Ventilation

Check if the same lab product or an alternative is used in the 5 most similar protocols

The majority of the patients started NIV in an elective setting. Patients had been admitted for diagnostic evaluation and NIV titration normally for 3-5 days. A mandatory back-up rate was always used and titration of inspiratory support and expiratory positive airway pressure were set with the aid of nocturnal monitoring with pulse oximeter, transcutaneous CO 2 and respiratory polygraphy. A further description of the ventilator titration algorithm is available in the Norwegian national guidelines for long term mechanical ventilation [38] . The included patients used the following mechanical ventilators: ResMed devices: VPAP III ST-A (n = 7), S8 VPAP IV ST (n = 20), S9 VPAP ST (n = 15), S9 VPAP ST-A (n = 5), Stellar 150 (n = 8) and Elisée 150 (n = 2). Philips Respironics devices: BIPAP AVAPS (n = 9) and BIPAP SYNCHRONY (n = 1).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
