The ReDe Mask™ is a disposable, single use oxygen face mask and respiration monitor that simultaneously provides supplemental oxygen to patients while also detecting exhalation and displaying a visual signal of each exhalation.

The ReDe Mask™ provides a patient with supplemental oxygen while monitoring respiration.   It provides a visual signal with each exhalation and a visual alarm when the patient stops breathing.  Patients who need supplemental oxygen are those with respiratory insufficiency, either from pre-existing disease or due to the administration of sedatives, narcotics, or anesthetics.  All such patients are at risk of developing an obstructed airway or further respiratory depression that would cause them to stop breathing.  Thus, it is critical that a patient receiving supplemental oxygen be observed so as to assure that they continue to breathe adequately.  Healthcare providers generally monitor ventilation by direct visualization of the patient.  This requires that the provider be in close proximity to the patient, but even when the provider is immediately next to the patient, they regularly don’t correctly note when ventilation has ceased.  The ReDe Mask™ provides a more sensitive monitor of respiration because it detects exhalation at the nose and/or mouth and thus provides a sure measure of actual ventilation. 

Indicator lights are used to interpret breathing. A green light  will illuminate with each breath greater than 8 breaths per minute. 

A yellow light will illuminate with each breath from 3 to 8 breaths per minute to give an early alert that the patient needs attention and intervention.

A red light will flash when the respiration rate falls below 3 breaths per minute to warn that the patient needs immediate attention and intervention. 

The ReDe Mask™ does not take the place of the monitoring performed by a health care provider and is not a standalone device; rather, it provides a readily observed indication of the patient’s breathing state. The visual signal provided by the ReDe Mask™ allows the provider to move about the patient while still monitoring the patient’s breathing.

The ReDe Mask™ may be used in any situation in which an oxygen mask is currently used, such as during procedures in which sedation is provided, during transport of patients post-operatively, in the post anesthesia care unit, and on patients with respiratory problems that are being observed in an ambulance, emergency room, or hospital floor. It allows the provider to quickly count the respiratory rate, even if they are not immediately adjacent to the patient.

Monitoring of ventilation has become a Joint Commission and American Society of Anesthesiologists standard in any patient who receives sedation. To date, these organizations have recommended end-tidal CO2 monitoring, or capnography, to accomplish this. Capnographs are expensive however, and require significant training and manipulation of detection catheters to use accurately.

The ReDe Mask™ is inexpensive and requires no external machinery, catheters, or training. Because ReDe Masks™ are so portable and can be stored wherever oxygen masks are currently kept, they may be made readily available to EMTs, nurses, CRNAs, anesthesiologists and any physician who provides sedation to a patient or who must monitor a patient’s breathing.

  • Provides supplemental oxygen to patients who have respiratory insufficiency due to administered sedatives or anesthetics.
  • Displays a green light as each breath is detected with a respiration rate is greater than 8 breaths per minute so health care providers can easily and reliably see that the patient is breathing normally.
  • Displays a yellow light as each breath is detected with a respiration rate is 3 to 8 breaths per minute to alert health care providers that the patient is not breathing normally and needs attention and intervention.
  • Displays a flashing red light if the respiration rate is less than 3 breaths per minute to warn health care providers that the patient has not taken a breath for a long period of time and needs immediate attention and intervention.
