Asynchronies in NIV With External Gas

May 7, 2021 updated by: Cristina Lalmolda-Puyol, Corporacion Parc Tauli

Trigger Asynchronies Induced by the Introduction of External Gas Into the Non-invasive Mechanical Ventilation Circuit: a Bench-to-bedside Study

NIV can be combined with other treatments that require to introduce gas into the circuit during the treatment. This external gas produces trigger asynchronies that worse depending on the model ventilator, trigger design and gas source. It is advisable to monitor NIV when these treatments are requiring in chronic NIV.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

patients from the Pulmonology Service of the Corporació Sanitària Parc Taulí (Sabadell, Barcelona) who met the following criteria: over 18 years of age, hospital admission for acute chronic respiratory failure, home NIV (single-limb system with intentional leakage) users for more than 6 months with adequate compliance (greater than or equal to 5 hours/night). Patients with underlying psychiatric disease were excluded. The study was conducted during the patient's predischarge phase (the same day or the day before)

Description

Inclusion Criteria:

  • over 18 years of age,
  • hospital admission for acute chronic respiratory failure,
  • home NIV (single-limb system with intentional leakage) users for more than 6 months with adequate compliance (greater than or equal to 5 hours/night).

Exclusion Criteria:

  • Patients with underlying psychiatric disease were excluded

Study Plan

This section provides details of the study plan, including how the study is designed and what the study is measuring.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

one group
patients from the Pulmonology Service of the Corporació Sanitària Parc Taulí (Sabadell, Barcelona) who met the following criteria: over 18 years of age, hospital admission for acute chronic respiratory failure, home NIV (single-limb system with intentional leakage) users for more than 6 months with adequate compliance (greater than or equal to 5 hours/night). Patients with underlying psychiatric disease were excluded. The study was conducted during the patient's predischarge phase (the same day or the day before)
Device: external gas during NIV
The procedure was performed in the patient's room during his or her hospital stay to avoid additional visits for study participation. The patient was placed in the supine position, and the usual ventilator interface was placed in a single-limb system, along with the commercial ventilator to be studied. The ventilator model were evaluated at bedside in random order. The parameters of the ventilator were the same as those that the patients used at home (that is, unlike the bench study, the sensitivity of the trigger was not modified). A external polygraph was used to moritor the study, with the incorporation of thoracic and abdominal bands and parasternal electromyography, to better evaluate asynchronies, in addition to pulse oximetry control. The ventilation periods were 1 minute (without gas, gas, without gas). This sequence was performed twice in each group of established conditions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Asynchronies ( yes or no)
Time Frame: 1 day
Presence of asynchronies identify by SOMNONIV´s algorithm during the gas treatment with NIV
1 day
Type of asynchronies
Time Frame: 1 day
autotrigger or innefective effort identify by SOMNONIV´s group algorithm, during the gas treatment with NIV
1 day

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
