Expert review of medical devices
-
This review examines the diffusion of modern medical devices in India by analyzing trends in India's cross-border trade in medical devices, its domestic medical device production and utilization by households. We explore the implications of this process of diffusion for the efficacy, cost-effectiveness and equitable use of new medical devices in India, and review recent efforts to regulate the Indian medical device sector.

Masimo Rad-57 Pulse CO-Oximeter for noninvasive carboxyhemoglobin measurement.
Noninvasive methods of body fluid chemical measurement have been expanding. New technologies are enabling the quantification of different compounds in the blood and interstitial tissues. One example of this is the pulse oximeter, which has facilitated the measurement of oxyhemoglobin rapidly and reliably without the requirement of blood-draws. ⋯ Since the presentation of CO poisoning is nonspecific and overlaps with many other conditions, and since the presence of environmental CO is often unknown, the detection of this condition was only possible in cases where the presence of CO was obvious or where the symptoms were severe. We now know, from studies conducted using the Rad-57, the only US FDA-approved device for noninvasive measurement of SpCO, that there are a significant number of patients who experience CO exposure but are nonsymptomatic. The Rad-57 provides a clinical justification for screening in the healthcare setting to identify patients with significant CO exposure who would otherwise be undetected.
