Twenty subjects, 10 unventilated and 10 ventilated patients, will undergo clinical auscultation of the heart and lungs with the Auscul-X, a conventional stethoscope and an electronic stethoscope (Littmann 3200).

Twenty subjects, 10 unventilated and 10 ventilated patients, will undergo clinical auscultation of the heart and lungs with an Auscul-X with wireless capability, a conventional stethoscope and an electronic stethoscope (Littmann 3200). Phase II shall begin upon appropriate Health Canada approvals for the Auscul-X with wireless capability.

The Auscul-X System (AusculSciences Canada, Inc.), is novel, professional grade, touch free, multichannel, touch-free electronic stethoscope with disposable elements designed to protect HCPs from exposure to infection diseases by allowing them to auscultate patients from a safe distance (10 feet away). The sensors can stay in place and enable providers to listen on-demand to a patient's heart and lungs over an extended period of time. This practice of distancing in the workplace is a key CDC and PHAC recommendation to protect the frontline HCP from exposure risk to the highly contagious COVID- 19 virus and other communicable diseases. The Auscul-X not only has the potential to better protect HCPs from infection, but also eliminates the potential transmission of pathogens through the use of conventional stethoscopes. In addition, the Auscul-X allows multiple HCPs to listen to the patient's heart and lung sounds simultaneously

To determine the feasibility of implementing Auscul-X in the critical/intensive care environment (ICCU and CSICU).

1. Determine if the quality of the real-time heart and lung sounds (Likert scale) for the Auscul-X will be similar to the conventional stethoscope and digital electronic stethoscope in the ICCU and CSICU (Appendix A).
2. Determine if the acoustic recordings taken as part of Phase II for the Auscul-X and conventional electronic stethoscope are similar (as evaluated by independent blinded cardiologists and respirologists using a Likert scale for acoustic and diagnostic quality (Appendix B)).
3. Determine if the acoustic recordings for the Auscul-X and conventional electronic stethoscope provide similar signal quality using objective acoustic metrics (e.g. signal to noise ratios, etc.) (Phase II only)
