"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?
