About this study
The purpose of this clinical study is to investigate how performing ventilations during pediatric resuscitation affects the ability to perform mental tasks. In particular, the effect on the participant's ability to perform dose calculations will be investigated. The aim is to draw conclusions about the effects of ventilations on other mental tasks.
How does the clinical trial work? This clinical trial will be conducted in several locations and will involve a total of 38 people. The study will be conducted by the Department of Anesthesiology of the Medical University of Vienna.

Participation in this clinical study is expected to last 30 minutes.
The following measures will be carried out exclusively for study reasons:
Depending on the sub-study you are participating in, different tasks will be performed:
Adult sub-study:
During this study, participants will be asked to perform mental arithmetic: Participants will be read a number every 2 seconds and have to add the last two in each case. The numbers are predetermined and randomly generated. At the end, we will evaluate how many results were correct.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Dose CalculationsBehavioural
Dose calculations either with or without performing ventilations during CPR (15:2)
VentilationsProcedure or surgery
Performing ventilations during CPR in a 15:2 manner
| Study group | Role | What they receive |
|---|---|---|
| Ventilations/CPR | Active comparator | Calculations made with/without performing ventilations - cross over design to decide what to do first, NASA-TLX will be measured Receives: Behavioral: Dose Calculations; Procedure: Ventilations |
| no ventilations/CPR | Active comparator | Calculations made with/without performing ventilations - cross over design to decide what to do first, NASA-TLX will be measured Receives: Behavioral: Dose Calculations |
What is being measured
The primary outcome is the main question the study is designed to answer.
Dose calculations
Number of correct calculations
Measured: during 2x2 minutes of inclusion
Secondary outcomes (1)
NASA-TLX
Nasa Task load index (min: 0, max: 120, higher scores mean higher cognitive load)
Measured: 4 minutes, 2 times in total per participant

Questions about this trial
What is this clinical trial studying?
A study testing Dose Calculations and Ventilations in people with Multitasking Behavior, run by Medical University of Vienna at 1 site in Austria.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Austria. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Dose calculations (time frame: during 2x2 minutes of inclusion). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Jan 2026.
