Several market players are taking active part in the global smart
pulse oximeters market.
The difference in
pulse oximeter readings between normal and occluded digits was statistically significant (p < 0.05).
This pragmatic study demonstrated that a fingertip
pulse oximeter was accurate (within 3% Sp[O.sub.2]) in perioperative patients with normal oxygenation (Sp[O.sub.2] [less than or equal to] 93%) compared with a bedside
pulse oximeter.
No change in vendor for either the
pulse oximeters or the methylene blue was identified.
Study inclusion criteria were as follows: therapeutic medical requirement for measurement of arterial oxygen saturation, age 18 or older, physiologic stability (<10% variation in HR, blood pressure, respiratory rate, temperature, and noninvasive oxygen saturation within the past 15 minutes), lack of physical impediments to proper use of the noninvasive
pulse oximeter devices, no ventilator setting changes or changes in inspired oxygen concentration in nonventilator dependent patients 10 minutes prior to data collection, and/or absence of a medical diagnosis of peripheral vascular disease or tetralogy of Fallot.
The
pulse oximeters are pre- calibrated against direct measurements of arterial blood oxygen saturation (Sp[O.sub.2]) in volunteers.
Various studies have demonstrated that health professionals' knowledge about the
pulse oximeter is not always ideal.
There are no inexpensive portable pulse CO-oximeters on the market and a
pulse oximeter cannot indicate impending carbon monoxide-related hypoxemia.
With the identification of this and other hemoglo bins that interfere with
pulse oximeter measurement, complex and expensive examinations might be avoided.
This makes use of it a "no brainer." However, there are still basic principles to understand when using the
pulse oximeter that ensure more accurate results.
