"If a pulse oximetry
test had been taken when Poppy was born, I feel she could have been treated earlier rather than getting to the stage of needing resuscitation.
The technique of pulse oximetry
is by the use of spectrophotometric emission., The ratio of absorbance at these wavelengths is calculated and calibrated against direct measurements of arterial SpO[sub]2., The waveform, which as seen on pulse oximeter help the clinician to eliminate all artefacts [Figure 1].
The mean drop in pulse oximetry
oxygen saturation reading between baseline and occluded digits was found to be 14.7%.
Patients with suspected OSA were admitted electively to a dedicated polysomnography room in a medical ward for unsupervised overnight oximetry
studies performed in other wards of the hospital during hospitalisation were also included.
Prediction of cognitive dysfunction and patients' outcome following valvular heart surgery and the role of cerebral oximetry
. Eur J Cardiothorac Surg 2008;33(4):560-5.
The presence of crosstalk in the reflectance-type pulse oximetry
sensor (conventional sensor) tended to overestimate overall oxygen saturation in subjects with dark skin, and the estimation error was particularly large at low oxygen saturation.
BP was measured 15 minutes after BP measured by pulse oximetry
A number of studies have been carried out worldwide, but there is lack of locally published literature about the use of pulse oximetry
as a screening tool to detect cCHD in newborns.
The criteria were as follows: (a) Sp[O.sub.2] was assessed with pulse oximetry
; (b) Sp[O.sub.2] was used to detect CHD subjects; (c) true positive (TP), false positive (FP), true negative (TN), and false negative (FN) or other data available for calculating them were reported.
(8) New Jersey was the first state to implement legislation mandating newborn pulse oximetry
While pulse oximetry
does not detect all CHDs, it is both highly specific (5) and cost-effective.
The FDA's Manufacturer and User Facility Device Experience (MAUDE) database includes the case of a patient who received methylene blue for localization of the parathyroid glands during parathyroidectomy and who developed a blister on the finger where the pulse oximetry
probe was placed.
