Exactitud y Errores de la Oximetría de Pulso

Concordance among Measurements Obtained by Three Pulse Oximeters Currently Used by Health Professionals

“…Authors [17,18] state of existence a variety of situations and objects that may affect the correct reading of the oximeter. which in this specific study have not been taken into account because the objective of this research was to study the concordances between the devices provided by the health institutions and those acquired by health professionals, being all measurements performed in the same environmental conditions.…”

“…On the other hand, from the point of view of electromedicine [18], it is relevant to emphasize the importance of sensors in this type of devices, their calibration and measurements accuracy because many mistakes have been made due to the different wavelengths in LED and the risks which these mistakes can produce in patients, especially in conditions with low levels of oxygen saturation in arterial blood. Therefore, more control and supervision is required from the manufacturers during the production of the pulse oximetry sensor or the selection of its suppliers.…”

“…As it was stated above, there exist clinical scenarios where oximetry loses its utility [18], as in the case of CO 2 intoxications and laryngitis. Therefore, the health staff who make use of this instrumentation need to be aware of this situation.…”

Factors which influence concordance among measurements obtained by different pulse oximeters currently used in some clinical situations

“…In the sample studied, no cases of oxygen intoxication or laryngitis were found. In this sense, the loss of utility of pulse oximetry, which is associated to these cases, as stated by some authors (Rodríguez, Garrido, Martínez, & García, ), cannot be proven.…”
