Groups/Cohorts Assigned Interventions
Patients undergoing heart surgery Device: TOSCA 500 monitor
transcutaneous ear lobe probe that monitors pulse rate, oxygen saturation and carbon dioxide levels

Detailed Description:

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.
