Abstract
A device for monitoring gases present in a breathing mask. A gas sensing element carried by the breathing mask senses the partial pressure of a gas present in the breathing mask and outputs signals corresponding to the sensed gas partial pressure. The gas sensing element may comprise a gas-sensing material configured to emit, in response to light excitation, an optical signal at an intensity corresponding to the partial pressure of a sensed gas.
Claims20
A respiratory gas monitoring device for monitoring gases present in a breathing mask, the device comprising:
- a breathing mask configured to be worn by a subject and to deliver gases to the subject for respiration;
- a first gas sensing element carried by the breathing mask and comprising a gas-sensing material configured to emit, in response to light excitation, an optical signal at an intensity corresponding to a partial pressure of a sensed gas.
A method for making a respiratory gas monitoring device, the method including the steps of:
- forming a breathing mask;
- embedding an optical fiber in a wall of the mask;
- and
- supporting a gas sensing element on the mask in optical communication with the optical fiber.
