Transcutaneous Carbon Dioxide Monitoring Post Cardiac Surgery: Incidence and Severity Resp Insufficiency

This observational study is to determine the baseline carbon dioxide and severity of
respiratory distress and acute respiratory failure (ARF)/respiratory arrest in the post
cardiac surgery patients in the first 24 hours on a monitored telemetry floor.

Inclusion Criteria:

- ASA Class 1, 2, 3, or 4 men and women who are having cardiac surgery by one of the
participating surgeons

Exclusion Criteria:

1. Subject has participated in a trial with any experimental drug or device trial within
30 days prior to enrollment in the study, or has ever been enrolled in this study;

2. Subject has a condition that would require an extensive amount of time off of 13
Roberts during the first 24 hours of admission to the telemetry unit. (e.g.,
hemodialysis);

3. Subject has a condition or allergy which would prohibit placing the probe on the
earlobes;

4. Subject is unable to undergo any procedure required by the protocol;

5. Subject has any other condition or factor which, in the Investigator's opinion, might
increase the risk to the subject; or

6. If female, subject is non-lactating, and is either:

- Not of childbearing potential, defined as postmenopausal for at least 1 year or
surgically sterile due to bilateral tubal ligation, bilateral oophorectomy, or
hysterectomy; or

- Of childbearing potential but is not pregnant as confirmed by negative serum
pregnancy test at time of screening.
