-- Studies Reveal A Need To Identify And Implement A Screening Procedure For Obstructive Sleep Apnea Prior To Surgery As Americans get heavier and heavier, the incidence of obstructive sleep apnea increases, and results from two clinical studies presented at ANESTHESIOLOGY 2010 reinforce the need for physicians to screen for the disorder prior to surgery in order to … [Read more...] about Anesthesiologists Underdiagnose OSA in Preoperative Patients

Understanding Pressure Transducers and Pressure Flow Signals
By Rick Swanson, RPSGT, CRTT A sensor or electrode acts as a transducer by taking one form of energy and converting it to another form of energy (i.e., a signal that is put into sleep data recording systems). A snore sensor takes the vibrations of snoring and produces an electrical signal of that vibration. Similarly, a pressure transducer measures the pressures of breathing … [Read more...] about Understanding Pressure Transducers and Pressure Flow Signals
How Reliable is the Diagnosis of Positional Obstructive Sleep Apnea? – Helen S. Driver, Farzad Saberi, Neela Chatha, Alison M. Urton, Peter Munt and Michael F. Fitzpatrick
Helen S. Driver, Farzad Saberi, Neela Chatha, Alison M. Urton, Peter Munt and Michael F. Fitzpatrick Abstract Objectives: To examine the reliability of a diagnosis of positional obstructive sleep apnea (OSA), with an apnea hypopnea index (AHI) for lateral sleep less than half the supine AHI (S-AHI) and less than 15 per hour, in patients using positional therapy for a full … [Read more...] about How Reliable is the Diagnosis of Positional Obstructive Sleep Apnea? – Helen S.

Dig Deeper, or It Is About Time We Standardlize our Tools – Noam Hadas
I have been active in sleep for the past 15 years, and I am excited to see the explosive growth in activity and the recognition that sleep medicine has achieved over this period. Indeed, there are very few examples in medicine that showed such a move from a curiosity item hailed by some researchers, into a well-accepted and active medical specialty. Still, in at least one … [Read more...] about Dig Deeper, or It Is About Time We Standardlize our Tools – Noam Hadas
