Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a small trial to test feasibility of an idea for a potential device. The investigators tested the feasibility of prompting a volunteer to breathe when their breathing had slowed down during administration of anesthetic drugs.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* American Society of Anesthesia (ASA) Class I and Class II male and female (non-pregnant/non-lactating) volunteers.
* Normal healthy individual as indicated by medical history and a physical examination.
* At least 18 years of age and less than 55 years of age.
* Negative drug screen.
* Uncomplicated airway anatomy.
* A Body Mass Index between 18 and 32.
* Are fully informed of the risks of entering the study and willingly provide written consent to enter the trial.
* Female subjects of child bearing potential will have a negative urine pregnancy test on the day the study is conducted.

Exclusion Criteria

* Known or suspected neurological pathologies.
* A history of significant alcohol or drug abuse, a history of allergy to opioids or propofol, or a history of chronic drug requirement or medical illness that is known to alter the pharmacokinetics or pharmacodynamics of remifentanil and propofol.
* Known obstructive sleep apnea.
* Known or suspected hypersensitivity to any compound present in the study.
* Any potential subject suffering from medical problems that, in the judgment of the investigator, presents unacceptable risk to the volunteer are not eligible for enrollment.
* Vulnerable subject groups such as prisoners and the mentally disabled that are traditionally excluded from medical research are also excluded.
* The potential subject has taken any medication within 2 days prior to chosen drug administration, with the exception of oral contraceptives.
* The potential subject is wearing artificial nails.
* A positive urine pregnancy test (females only)
* Female subjects who are currently lactating \& breast-feeding.
* A positive drug-screening test.
* The subject consumed food or fluids within 8 hours prior to start of each chosen drug administration.
* Any medications or alcohol within 2 days prior to start of the chosen drug administration, with the exception of oral contraceptives.
