A clinical study enrolling 70 subjects to: * evaluate the user performance of the Pivot Breath Sensor * compare measurements from the Pivot Breath Sensor to a similar device * assess user documentation comprehension * obtain feedback on the Pivot Breath Sensor via rating scales. No medical decisions will be made related to test results.
The objectives of this performance study are to: * Non-invasively measure carbon monoxide (CO) levels in the exhaled breath of study subjects using two different types of measurement devices. * We will assess the correlation between the measured CO levels (in parts per million, or ppm) of the study CO breath sensor (Carrot Inc.) and a similar device. * assess user documentation comprehension * obtain feedback on the Pivot Breath Sensor via rating scales.

User Performance of Pivot Breath Sensor
Assess user performance of the study device at a single visit. Participants will be observed if they can set up the Pivot Breath Sensor, and whether they can use the device. Observer ratings include 'Successful' and 'Unsuccessful'. Specific attention will be given to assess if any harms can occur from observed use errors. "Successful" = the participant was able to complete the task independently, safely, effectively, and without difficulty. "Unsuccessful" = the participant was unable to complete the task independently, safely, effectively, and/or without difficulty. Includes instances where the participant required study moderator assistance.
Time frame: Each study session lasted up to 60 minutes per participant. Use performance was assessed at approximately 10-15 minutes into the study session.
Compare Performance of Pivot Breath Sensor With a Similar Device.
Compare study device performance with a similar device at a single visit. Participants will then be asked to use a similar CO breath sensor device. The correlation between the measured CO levels (in parts per million, or ppm) of the study CO breath sensor (Carrot Sense) and the similar breath sensor will be assessed.
Time frame: Each study session lasted up to 60 minutes per participant.
User Documentation Assessment With Observer Ratings
Participant understanding of user documentation will be assessed at single visit through interpretation of three different CO test results: green, orange, and red. User documentation used for the interpretation of each result includes: packaging information, quick start guide and user manual. Observer ratings include 'Successful' and 'Unsuccessful'. "Successful" = the participant was able to complete the task independently, safely, effectively, and without difficulty. "Unsuccessful" = the participant was unable to complete the task independently, safely, effectively, and/or without difficulty. Includes instances where the participant required study moderator assistance. Participant will be asked to assess the user documentation throughout the study session and will take approximately 10 minutes.

Time frame: Each study session lasted up to 60 minutes per participant. The user documentation assessment with observer ratings was done between approximately 10 and 35 minutes into the study session.
Participant Feedback Using Rating Scale
Participant will be asked to provide ratings on the following: * How would you rate the ease or difficulty using the device? * How clear or unclear was the Quick Start Guide? Why? * How clear or unclear was the Packaging? Why? * How clear or unclear was the User Manual on the iPad? Why? * Overall, how clear or unclear were the provided reference materials? Why? * How easy or difficult was it to understand and interpret the test results? Why? The participant will use the following rating scale: 5 - Very Easy 4 - Easy 3 - Neither Easy nor Difficult 2 - Difficult 1 - Very Difficult Not Applicable Participant will provide the ratings prior to the conclusion of the study session. Participant assessment with questionnaire rating scales will take approximately 1-2 minutes each.
Time frame: Each study session lasted up to 60 minutes per participant. Use performance was assessed with rating scales at approximately 35 minutes into the study session.
