"Excellent instructor!
Able to get point across in a very 
understandable manner."

INTRODUCTION

Interactions between the heart and lungs are complex, fascinating, andmultifaceted. This seminar is designed to explore the primary determinantsof heart lung interactions during health and disease, including venous return, right ventricular performance, pulmonary blood flow, intrapulmonary gasexchange, ventricular interdependence, left ventricular preload and afterload, effects of ventilation on regional blood flow, and others. 

This one-day seminar will focus on direct clinical application of cardiopulmonary physiology, with special emphasis on interventions intended to optimize both gas exchange and cardiac functionin critically ill patients undergoing ventilatory support.


"Barbara Mims has excellent people skills.
Her teaching technique made this 
a good learning experience." 

TARGET AUDIENCE

This seminar is intended for experienced critical care nurses and respiratory care practitioners.

SAMPLE QUESTIONS 

What is the relationship between airway pressure, pleural pressure, intrathoracic pressure, pericardial pressure, and lung volumes?

How can ventilation with smaller tidal volumes reduce intrathoracic pressure in an ARDS patient? How can this affect cardiac output?

How can you estimate the role that lung compliance plays in determining the effect of PEEP on the PCWP?

How can the exaggerated decrease in intrathoracic pressure associated with vigorous inspiratory efforts in some patients with pulmonary disease increase left ventricular afterload and thus compromise cardiac output?

What ventilator adjustments can be made to minimize the adverse hemodynamic effects of mechanical ventilation?

What ventilator adjustments can maximize beneficial hemodynamic effects of mechanical ventilation in patients with impaired cardiac contractility?

How does the use of CPAP reduce left ventricular afterload and provide hemodynamic support in the patient with heart failure?

How does maintained spontaneous breathing during ventilatory support improve: 
- pulmonary gas exchange?
- systemic blood flow? 
- oxygen supply to the tissues?

How can a decrease in cardiac output cause a decrease in arterial oxygen content?

How can a decrease in cardiac output cause an increase in arterial carbon dioxide?
