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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This was a prospective, randomized, crossover study to assess the tidal volume delivered using a standard and modified bag valve mask (BVM) device in a manikin airway model. Data was collected from July 2015 through October 2015 at the San Antonio Military Medical Center. Emergency medicine providers (physicians, physician assistants, residents, nurses, medics) were randomized to device order. Prior to participation each participant filled out a survey indicating their job status, gender, years of medical experience, and experience level with BVM ventilation. Hand grip strength and size (length, width, span) were measured. Each participant was then asked to provide BVM ventilation using the assigned devices at a rate of 10 breaths per minute for 3 minutes for a total of 30 breaths. Tidal volume of each delivered breath was recorded in milliliters. After a 3 minute rest period, testing was repeated with the second device. After ventilation with each device, participants completed an anonymous questionnaire that used a Likert scale to assess perceived qualities of the modified device including ease of use, ability to provide a superior mask seal, willingness to use in an emergency situation, and overall preference between the two devices. Each participant served as his/her own control.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.

Experimental: Modified Ambu Spur II bag valve mask
A health volunteer uses a modified Ambu Spur II bag valve mask with integrated internal handle (experimental device, not yet FDA approved) to deliver 10 breaths per minute for 3 minutes to a manikin (IngMar RespiTrainer manikin model).
Device: Modified Ambu Spur II bag valve mask
Subjects deliver breaths to manikin (IngMar RespiTrainer manikin model) a modified Ambu Spur II bag valve mask with integrated internal handle
Active Comparator: Conventional Ambu Spur II bag valve mask
A health volunteer uses a conventional Ambu Spur II bag valve mask to deliver 10 breaths per minute for 3 minutes to a manikin (IngMar RespiTrainer manikin model).
Device: Conventional Ambu Spur II bag valve mask
Subjects deliver breaths to manikin (IngMar RespiTrainer manikin model) a conventional Ambu Spur II bag valve mask

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
Mean Received Tidal Volume
Time Frame: 3 minutes
Each participant was asked to provide BVM ventilation using the assigned devices at a rate of 10 breaths per minute for 3 minutes for a total of 30 breaths. Tidal volume of each delivered breath was recorded in milliliters
3 minutes

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
Time Frame
Modified Bag Valve Mask (BVM) Ease of Use
Time Frame: Within 10 minutes of study completion
Likert scale measuring subject's perceived ease of use of the modified BVM device from not at all easy to use (1) to very easy to use (5).
Within 10 minutes of study completion
Modified Bag Valve Mask (BVM) Better Seal Formation
Time Frame: Within 10 minutes of study completion
Subjects response using a Likert scale (1-5) regarding their perceptions of whether the modified BVM forms a better seal compared to a standard BVM: 1 (much worse seal formation) to 5 (much better seal formation).
Within 10 minutes of study completion
Modified Bag Valve Mask (BVM) Willingness to Use in Emergency Situation
Time Frame: Within 10 minutes of study completion
Subject reported willingness to use the modified BVM in a real life emergency situation as measured on a Likert scale ranging 1 (not at all willing to use) to 5 (very willing to use).
Within 10 minutes of study completion
Number of Participants Who Preferred the Modified Bag Valve Mask (BVM)
Time Frame: Within 10 minutes of study completion
Each subject provides a binary response as to whether he/she overall prefers using the modified BVM instead of the conventional BVM.
