Miniature In-line Respirator

3 listopada 2026 zaktualizowane przez: National Institutes of Health Clinical Center (CC)

First-In-Human Trial of Miniature In-Line, Pressure-Cycled, Emergency Respirator Device in Human Organ Donors

This first-in-human pilot study will test an investigational miniature breathing device called the Hope inVent. The device is a small, single-use, in-line respirator that connects to a breathing tube and uses compressed oxygen to help move air in and out of the lungs. It has no moving parts and is designed to provide short-term breathing support in situations where standard ventilators may not be available, such as emergencies, disasters, battlefield settings, transport, or ventilator shortages.

The study will enroll up to 5 brain-dead organ donors who are already receiving mechanical ventilation at the Gift of Life Donor Care Center at the Hospital of the University of Pennsylvania. Donors will only be included after authorization for organ donation and research has been obtained through standard procedures. Donors who may donate lungs or who have significant lung disease will not be included.

During the study, investigators will briefly replace the standard ventilator with the Hope inVent device for up to 15 minutes. The standard ventilator will remain immediately available, and the donor will be continuously monitored by the clinical and research teams. Investigators will measure whether the device can maintain acceptable breathing measures, including oxygen level and carbon dioxide level. They will also record breathing pressures and tidal volume, which is the amount of air delivered with each breath. If the device does not perform as expected or if any safety concern occurs, the donor will be returned immediately to the standard ventilator.

There is no direct benefit to the organ donor. Information from this study may help determine whether this type of simple, low-cost breathing device could be useful for future patients who need emergency or short-term ventilator support when standard ventilators are not available.

Szczegółowy opis

Study Description:

Proof of Concept pilot study to support use of a miniature in-line patient respirator for patient ventilation needs.

Objectives:

Primary Objective:

To assess the effectiveness of the miniature respirator to ventilate intubated braindead research donors while maintaining respiratory measures within acceptable range.

Secondary Objective

The miniature respirator performs as designed and tested in a lung simulator.

Endpoints:

Primary Endpoint:

A binary variable equal to 1 ("success") if both of the following criteria are met (during the placement of the test device):

  1. the respirator maintains the end tidal CO(2) between 35- and 45-mm Hg;

    and

  2. the O(2) saturation measured by pulse oximetry is > 94%.

Otherwise, the primary endpoint is equal to 0 ("failure").

Secondary Endpoints:

Binary variables equal to 1 ("success") if tidal volume and airway pressure settings (PEEP and maximum peak airway pressure) are within 30% of predicted values. Otherwise, the secondary endpoints are equal to 0 ("failure").

Eksperymentalny: Hope inVent Miniature In-line Respirator

All enrolled brain-dead organ donors who meet eligibility criteria will receive the investigational Green Hope inVent miniature in-line, pressure-cycled respirator for up to 15 minutes. Respiratory and physiologic measures will be collected before device placement while the donor is on the standard mechanical ventilator and during use of the Hope inVent device. Each donor serves as their own control; there is no separate comparator arm. The standard ventilator will remain available, and donors will be returned to standard ventilation after testing or earlier if safety or performance criteria require.

The Hope inVent is an investigational, single-use, miniature in-line respirator designed to provide short-term ventilatory support for intubated individuals. The device is a 3D-printed, pressure-cycled, gas-powered respirator with no moving parts. It connects to the endotracheal tube breathing circuit and uses compressed oxygen as its power source. In this study, only the Green Hope inVent model will be used. The device cycles between fixed pressure settings: peak inspiratory pressure of 18 cm H2O and positive end-expiratory pressure of 6 cm H2O. Enrolled brain-dead research donors will be placed on the device once for up to 15 minutes, with continuous respiratory and physiologic monitoring. The donor will then be returned to the standard mechanical ventilator.

Success is defined as maintaining both end-tidal carbon dioxide between 35 and 45 mm Hg and oxygen saturation by pulse oximetry greater than 94% during placement of the Hope inVent device. If either criterion is not met, or if device use is stopped early because of inadequate ventilation or oxygenation, the outcome is classified as failure.
