Overview

The study aims to find if using a Biphasic Cuirass Ventilation is as effective as using a Non invasive Positive Pressure Ventilation in patients admitted with acute hypercapnic respiratory failure.

Description

Patients presenting via Emergency Room or inpatients who are noted to be in acute hypercapnic respiratory failure will be approached for consent and if they are agreeable will be randomized to the standard of care arm which would be the use of Bilevel Positive pressure ventilation via face mask vs the intervention arm which would use the Biphasic Cuirass Ventilation.

Patients will be monitored and treated in the Medical ICU and will be regularly clinically assessed as per usual standard of care. The study investigators will obtain periodic Arterial/Venous Blood gas sampling to assess for improvement or lack thereof in patients Carbon dioxide levels.

If patients' condition doesn't improve or deteriorates their primary treating physician will have full authority to withdraw such patients from study and or change the modality of the patient's treatment.

This is a pilot study, and the investigators are aiming to compare the success rate of Biphasic cuirass ventilation when compared to non-invasive positive pressure ventilation.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
