How Effective Leaders Harness the Future.

Human beings are fundamentally future oriented. Most of our decisions and undertakings are for the sake of a future to which we are committed or obligated. This future orientation is essential to effective leadership in health care, especially during this time of significant reform, when people are at risk of becoming cynical and disengaged.

Precise quantification of pressure flow waveforms of a pulsatile ventricular assist device.

Unreliable quantification of flow pulsatility has hampered many efforts to assess the importance of pulsatile perfusion. Generation of pulsatile flow depends upon an energy gradient. It is necessary to quantify pressure flow waveforms in terms of hemodynamic energy levels to make a valid comparison between perfusion modes during chronic support.
