Patients who spent much of their sleep time getting less than 90% oxyhemoglobin saturation
were nearly nine times more likely to die of cancer during the study, compared with controls, said Dr.
Chest and abdominal efforts were recorded using inductive plethysmography and arterial oxyhemoglobin saturation
by pulse oximetry with a finger probe.
It is imperative that the practitioners understand that the oxyhemoglobin saturation
reported by the pulse oximeter should be considered inaccurate (18).
Near-infrared spectroscopy (NIRS) is a relatively fast and noninvasive method to measure tissue oxyhemoglobin saturation
During each session, heart rate, blood pressure and exertional symptoms were monitored, Oxyhemoglobin saturation
was monitored by a respiratory therapist blind to the study.
Pulse oximetry is a noninvasive method of photoelectrically determining the oxyhemoglobin saturation
of arterial blood.
Masimo Rainbow SET Is the First and Only Way for Clinicians to Continuously and Noninvasively Monitor Their Patients' Carboxyhemoglobin, Methemoglobin, and Oxyhemoglobin Saturation
as Well as Pulse Rate and Perfusion Index
The type, number and duration of respiratory events were noted, as well as the median and minimum oxyhemoglobin saturation
In 10 women referred for sleep-disordered breathing in the third trimester, significant improvements were found in the apnea-hypopnea index, and minimum arterial oxyhemoglobin saturation
occurred in all 10 postnatally (Sleep 2005;28:737-41).
In 10 women referred for sleep-disordered breathing in the third trimester, the investigators found that significant improvements in the apnea-hypopnea index and minimum arterial oxyhemoglobin saturation
occurred in all 10 postnatally.
Among variables with frequently cited set-points are body weight, deep-body temperature, heart rate, arterial oxyhemoglobin saturation
, blood viscosity, and extra- and intracellular pH and salinity.
Jugular venous oximetry is achieved by cannulation of the internal jugular vein near the jugular bulb, with continuous or intermittent monitoring of jugular bulb oxyhemoglobin saturation
