The capability for externally applied rhythmic limb compressions to improve the outcomes of patients with peripheral artery disease has been recognized for nearly a century. Modern technology has permitted the development of portable and cost-effective intermittent pneumatic compression (IPC) systems to be made readily available for affordable at-home use. Mounting clinical evidence attests to ...

BACKGROUND NO bioavailability has not been systematically examined in congenital heart disease (CHD). To assess NO in patients with CHD, we measured nasal NO (nNO) generated by the nasal epithelia, given blood NO is difficult to measure (half-life, <2 ms). Given NO's role in hemodynamic regulation and the association of NO bioavailability with heart failure risk, we hypothesized NO levels may d...

Physiology in microgravity is a challenging field of research because of limited resources. Though humans have been in space for 50 years most meaningful data has been collected only within the last 15 years. While expensive studies with small sample sizes make obtaining and interpreting data difficult, some general conclusions about the human physiological response to microgravity can be drawn...

Owing to multiplanar imaging capabilities and excellent tissue characterization, MRI can facilitate definitive diagnosis of benign conditions of the female pelvis. The purpose of this chapter is to review the spectrum of common benign conditions of the female pelvis and to illustrate the MRI features of these conditions, with an emphasis on the key imaging characteristics to suggest accurate di...

Anatomic and Physiologic Considerations Nerve fibers subserving the sense of smell have their cells of origin in the mucous membrane of the upper and posterior parts of the nasal cavity (superior turbinates and nasal septum). The entire olfactory mucosa covers an area of about 2.5 cm2 and contains three cell types—the olfactory or receptor cells (which number between 6 and 10 mil l ion in each ...

MUCH has been written relative to the physiologic abnormalities produced by mitral stenosis and insufficiency. Most of the data and the concepts derived therefrom have been obtained by right heart catheterization.'--8 The introduction of left heart and combined heart catheterization9-19 has greatly enhanced the value of physiologic study in patients with rheumatic mitral valve disease and has p...

INTRODUCTION Patients triaged to tertiary care centers frequently undergo rotary-wing transport and may be exposed to additional risk for adverse events. The incidence of physiologic adverse events and their predisposing factors in mechanically ventilated patients undergoing aeromedical transport are unknown. METHODS We performed a retrospective review of flight records of all interfacility, ...
