Noninvasive Ventilation Comparison Study

The protocol was approved by the institutional review board (Comité de Protection des Personnes Sud Méditéranée IV, Montpellier; approval number 2012-A00098-35), and written informed consent was obtained from each subject. Twelve healthy volunteers were studied in a semi-recumbent position. The subjects (three women and nine men, age 30 ± 9 years) were all nonsmokers and had a body mass index of 24 ± 4 kg/m2. NIV was delivered trough an FM (Performatrak, Philips Respironics), HS (NIV-Castar R), and HN (NIV-Castar R Next), using an ICU ventilator equipped with software for air-leaks compensation (NIV module) (Servo-I, Maquet, Solna, Sweden) set in PS ventilation mode.

Ventilation Circuits and Mask Evaluation

We used a Vivo 50 ventilator (Breas, Gothenburg, Sweden). Ventilatory settings
are detailed in Table
1
. Pressure Support ventilation was delivered to a member of the team
(BM) with a voluntary respiratory rate of approximately 20 breaths/min. The mask
used was a Performatrak (Philips, Pennsylvania, USA) which is a non-vented
mask.
For both experiment 1 and 2, the circuits used are detailed in Figure 1. All circuits
contained a bacterial/viral filter (Intersurgical, Wokingham, UK) placed between
the subject (test lung or member of the research team) and the exhalation port
or valve.

Non-invasive ventilation for respiratory support

Check if the same lab product or an alternative is used in the 5 most similar protocols
NIV was performed with Respironics V60 Ventilator (Philips Respironics: USA) in S/T mode, as recommended in our unit protocol: the pressure support was increased by 2 cmH2O steps depending on the patient’s tolerance, up to a maximum of 20 cmH2O to reach a tidal volume of 8 mL/kg of ideal body weight. The expiratory positive airway pressure was between 5 cmH2O and 10 cmH2O. The FiO2 was adapted to reach an oxygen saturation of 90%–92%. The interface was a full-face mask (PerformaTrak, Philips Respironics).

NIV in Emergency and ICU Settings

Check if the same lab product or an alternative is used in the 5 most similar protocols
NIV was started in the emergency room and was carried on in the ICU. According to our local protocol, the same turbine-driven portable ventilator (BiPAP Vision, Philips Respironics, Murrysville, PA) and oronasal mask (PerformaTrak, Philips Respironics, Murrysville, PA) were used in all patients [18] (link). The patients were gently placed in the sitting position and received reassuring explanations about the technique. The BiPAP Vision was equipped with its specific single branch circuit including an intentional leak, which was calibrated before each use and placed the closest as possible to the mask to prevent rebreathing phenomenon. Bilevel positive pressure targeted mode was delivered with the BiPAP Vision. The settings were adjusted at the discretion of the attending clinician. Active humidification (MR 850, Fischer & Paykel Healthcare, Auckland, New Zealand) was incorporated among the inspiratory circuit of the ventilator. NIV was continuously applied until a significant clinical improvement of the patient occurred. If effective, gradual reduction of the duration of NIV could be then considered by the attending physician.

Noninvasive Ventilation for Acute Hypercapnic Respiratory Failure

Check if the same lab product or an alternative is used in the 5 most similar protocols
Once the diagnosis of acute hypercapnic respiratory failure was made, NIV was started by using a nonvented full face mask (PerformaTrak, Philips Respironics, Murrysville, Pennsylvania) and a turbine-driven portable ventilator (BiPAP Vision, Philips Respironics) connected via its single-limb circuit. The NIV circuit was equipped with a precalibrated intentional air leak that was positioned as close as possible to the subject. The subject was comfortably placed in the sitting position, either in the bed or in a chair, and received explanations regarding the NIV technique and the interface. The spontaneous-timed mode of the BiPAP Vision ventilator was used with adaptive triggering and cycling. The ventilator settings were left to the discretion of the physician in charge. The criteria used to define NIV success and NIV failure are fully described in previous publications. 11, 14 When NIV failed to reverse the acute respiratory failure episode, compassionate care with terminal sedation was instituted and the family was invited to remain with the dying patient until the end.

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.
