This course provides a detailed study of the structure and function of the heart and lungs, including their interdependency. The course discusses acid-base physiology including arterial blood gas interpretation and its relationship to normal and abnormal physiologic states.

Polk State College Mission and Program Outcomes

Polk State College, a quality driven institution, transforms lives through the power of education by providing access to affordable associate and baccalaureate degrees, career certificates, and workforce employment programs, delivered by diverse, qualified faculty and staff. In line with this purpose, Polk State’s Associate in Science and baccalaureate degree programs develop competence in various career-related skills. This course focuses on the development of competencies related to the following program outcomes:

To provide the student with a sound basis in the scientific principles which form the foundation of respiratory care practice.
To acquaint the student with the normal and abnormal states of cardiopulmonary physiology which are observed and/or treated in the clinical setting.
To promote and aid students in developing good study habits which will be a resource for continued personal and professional growth.

Course Objectives:

The student will (be)

Identify, describe and discuss the structure and function of the lungs and heart to 78% proficiency on a written test.
Define and describe the processes, and name the respiratory therapy method(s) of treatment to 78% proficiency on a written test.
Interpret arterial blood gas results to 78% proficiency on a written test.

Course Content:

The foundation for cardiopulmonary anatomy and physiology is formed. Normal and abnormal physiology will be presented. Acid-base physiology to include arterial blood puncture techniques and interpretation of the arterial blood analysis will be discussed.

College-Level Communication and Computation Skills

State Rule 6A-10.030 does not apply to this course.

Student Help

The professor is available for help during posted hours and by appointment during other non-class hours. Each student is encouraged to seek assistance from the professor. To further the educational process, the Learning Resources Centers, comprised of the campus Teaching/Learning and Computing Centers (TLCCs), JDA Student Success Center, and campus libraries, are available for student use. Each resource provides qualified staff and up-to-date equipment and facilities to promote academic success. The TLCCs and JDA Student Success Center provide tutoring services, computing resources, and other instructional support. The library provides information resources, individual and group study space, research assistance, information literacy instruction, and computing resources. Each facility provides free wireless access to the Internet. The Polk State College Library, Student Success Center, and TLCC hours of operation and tutoring schedules are posted at each facility and on the College website.

Withdrawing From a Course

A student may officially withdraw from a course during any given term, provided he or she follows the appropriate policy and procedure. Following the conclusion of the Drop period, students may officially withdraw without receiving a grade from any course, provided they do so no later than the published withdrawal deadline. The published deadline reflects approximately (but no more than) 70% of the term, based upon the course’s scheduled duration. It is the student’s responsibility to submit these withdrawal forms; failure to do so may result in a grade of F in the course. Under the Forgiveness Policy, a student is allowed only three attempts in any one course: one initial enrollment and two repeats. A student is not allowed to withdraw from a third course attempt. Limited admission programs may have specific guidelines regarding course withdrawal that vary from this policy; these guidelines are listed in the specific program handbooks. If a student stops attending class, the grade earned, usually an F, is assigned and posted. Prior to withdrawing from a course, the student should consult with the Financial Aid Office to determine what impact, if any, withdrawal from the course will have on his or her financial aid status. A student cannot use course withdrawal to avoid academic dishonesty penalties. A student who has been penalized for academic dishonesty in a course is not eligible to withdraw from the course.

Repeating a Course

Under the Forgiveness Policy, a student is allowed only three attempts in any one college credit course: one initial enrollment and two repeats. Under certain circumstances, a student may petition to repeat a credit course beyond the third attempt. Limited admission programs may have specific guidelines regarding repeating courses that vary from this policy; these guidelines are listed in the specific handbooks. The student should be aware that repeating a course may result in a higher course cost. A course cannot be repeated unless the previously earned grade is a D, F, or W (the Polk State Catalog provides further details regarding this process). Prior to repeating a course, the student should consult with the Financial Aid Office to determine what impact, if any, repeating the course will have on his or her financial aid status.

Academic Dishonesty

Each student is responsible for his or her work. It is assumed that each student is honest and will abide by this standard; however, in the event that there is an indication or suspicion of cheating or plagiarism, the situation shall be dealt with in accordance with the published College policy. Copies of this policy are available in the Student Services Office. More specific information can be found in the Course Syllabus.

Information Technology Access/Use Policy

The information technology resources provided by Polk State College (this includes, but is not limited to, telephones, computers, the Polk State Local Area and Wide Area Networks, and the Internet) must be used for academic purposes only. Use of these resources is a privilege, not a right. Inappropriate use can result in revocation or suspension of this privilege.

Equal Opportunity For Students With Disabilities

The College complies with The Americans with Disabilities Act and provides equal educational opportunity for qualified individuals. A student with a disability who requires special accommodations or auxiliary aids under The Americans with Disabilities Act (ADA) should contact the Coordinator or Director of Disability Services. Note: Limited admission programs may have performance restrictions that apply. Restrictions (where applicable) are outlined in each program’s student handbook.

Evaluative Criteria:

Multiple choice tests , take-home and scheduled in class, quizzes, equipment/procedure check-offs, individual projects and assignments, group activities and professional behaviors.

Assignments and/or projects that may be assigned are to be submitted on the designated date, during the class period. No assignments or projects will be accepted after the class has adjourned, unless arrangements have been made between the student and the instructor. Students failing to submit assignments on time and not following procedures will get a zero (0). Final Course grade will be determined as an average of tests, quizzes, and the final comprehensive exam. A grade of “C” or 78% must be made to satisfactorily complete this course. Professional behavior will be 15% of the final grade. This will include behavior (see the AARC Statement of Ethics and Professional Conduct) as well as participation in assigned activities as the Polk Fall Fest, Respiratory Care Week and other social activities.

Grading Scale:
92.5 – 100                 A
88.5 – 92.4                B+
83.5 – 88.4                B
80.5 – 83.4                C+
77.5 -80.4                  C
70.5- 77.4                  D+
65.5-70.4                   D
Below 65.4                 F

Attendance:

Regular attendance in the classroom and laboratory sessions is mandatory. When three (3) unexcused absences are accumulated, the student may be issued a written warning. If an additional absence occurs, the student may be dropped from the program in accordance with the attendance policies outlined in the general college catalog. In no case will a student receive a passing grade for a course if more than twenty-percent (20%) of scheduled lectures is missed.

Work Missed:

No Make-ups will be given for missed exams, quizzes, assignments, or projects unless the condition falls under extended medical, military leave, or family emergency . If any of these work items are missed, the grade assigned will be a zero (0). Students who need to be on extended medical, military leave and/or family emergency must submit copies of official documents to the program manager.
