About

The VRI device may provide a complementary diagnostic tool for lung examination and aid the physician in determining whether a chest x-ray should be performed.

Full description

This study is a prospective, single center study to determine the value of VRI images as an aid in determining whether a chest x ray is necessary to evaluate children presenting with acute respiratory complaints.

Study participants will be children, selected from the Emergency Department (ED), who were designated to undergo a PA and Left Lateral CXR because of acute respiratory complaints such as a new respiratory condition, acute cough, onset of shortness of breath, or fever.

Patients who meet the study inclusion and exclusion criteria will be enrolled and will be recorded by the VRI device.

A technician will perform a CXR on the enrolled patients. The CXR and the VRI will be performed on the same day within 6 hours of each other.

VRI readers, who are blinded to the patient's CXR, history, and physical exam, will evaluate the VRI recording. The VRI reader will review the VRI images and, using the lexicon of images supplied by Deep Breeze, determine whether the VRI is normal or abnormal.

Certified radiologists will review the patient's CXR and will determine whether the CXR is normal or abnormal based solely on the CXR.

The VRI readers determination of normal or abnormal for each subject will be compared to the radiologists determination of normal or abnormal CXR for each subject.

Enrollment: 80 estimated patients

Sex: All

Ages: 3 to 18 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Subject's parent or legal guardian, is able and willing to read the Informed Consent, understands the Informed Consent, and provides written Informed Consent for the subject; if the minor child is in fact able to give consent, the minor's consent must be obtained in addition to the consent of the minor's legal guardian.

3. Patient presented with acute respiratory complaints, acute cough, onset of shortness of breath, or fever.
4. Patient referred by ED physician and presented for CXR.

Exclusion criteria

1. Body habitus or skin condition that might prevent the placement of the sound sensors on the back (e.g. severe scoliosis, kyphosis, chest wall deformation, skin lesion on the back or compression fracture);
2. Potentially contagious skin lesion on the back;
3. Subject has had lung surgery;
4. Subject was prescribed the CXR for monitoring or follow up of a lung condition that pre-existed the current, acute symptoms.
