Pulse Oximetry is usedmainly in many hospital environments and us used as a non-invasive method ofobtaining blood oxygen saturation or (SpO2) in patients. To find the amount of oxygensaturation the devise uses and reads different wavelengths of light and thencompares the amount of light that was absorbed and then transcribing it intocalculations giving us the percentage of oxygen saturation. This came to be abasic practice in the medical field as one did not have to analyze bloodsamples, and it is cost effective and is able to use in a rapid response emergency.
It has also been found beneficial to those especially who are receiving oxygen typetherapy to make sure that the patient is receiving an adequate supply and isnot being hindered by asthma or chronic obstructive pulmonary disease. However bylooking at a pulse oximeter one would conclude that there is no complicationwhen managing the device and appears to be rather simple there are complexitiesthat go with the devise and understanding the readings. This lead to ahypothesis that many other studies have shown that the knowledge based ofhealth care professionals relating to the use of pulse oximeters is insufficientspecifically aimed at nurses.
Themethods used were a type of cross sectional and multicenter study was conductedin the emergency department, adult intensive care units, and department of anesthesiology.In a clinical practices it’s customary for doctors and nurses to be able to useand interpret the pulse oximeters results that are taken from a patient. Beingunable to accurately interpret the data can lead to potential miscommunicationsand misdiagnosis and compromise the patient entirely. In the study 198 nursesbecame participants including 90 coming from the intensive care unit, 22 camefrom the department of anesthesiology and the final remaining nurses which madeup 86 came from the emergency department all having a minimum of a year ofworking in a clinical setting. Those who did not meet the requirements were notallowed to participate in the experiment.
The form of the study was conductedby a questionnaire that was turned in at the end of their shift. First part wascollecting data on the basic profile of the participant including age, years worked,education and so forth. The second part contained a true or false format aimedat 22 question that were specific to pulse oximetry.
The results came as a satisfactory level of reliabilityas scores for the knowledge based scored between 6 and 18 as the highest score being22 and the median being 12. Scores for pulse oximetry functioning came toaverage of 5 and conditions effecting its accuracy had a median of 6. The knowledgebased interpretation was varied by department as shown that the participantsthat came from the emergency room and intensive care units scored higher thatof the anesthesiology department. For example in table 3 shows the first 11questions of the questionnaire that the nurses would fill out at the end oftheir shift. This table shows the number and percentage that received thecorrect responses and not showing those that were incorrect. By look at thistable at first glance we can conclude from the first 11 questions that the intensivecare unit and the anesthesiology department scored the highest having each havingthe highest percentage on 4 questions each then the other departments while theemergency room had 3 question that had a higher percentage than the other departments.
There were also questions where the majority of either one or more departmentsscored lower than 50 percent demonstrating their lack of knowledge based on thequestion that was given as in question 3,4,5,7,8,9. This data for the firsthalf of the question does show strong knowledge based results of understanding theprinciples or concepts of the question however it also shows a misunderstandingof knowledge based questions as well. I believe to that experience with thepulse oximeter gave way to a better understanding of how it worked. The endresult came to that only about 54% of the nurses had a limited amount of knowledgeconcerning the uses and interpretation of pulse oximeters. This study was preformed to have a better understandingof the level of knowledge that nurses would have on pulse oximetry. The final conclusioncame to that nurses have a satisfactory level of knowledge when relating to thefactors and conditions that may affect the pulse oximeters when being used whichcan be estimated as having a better understanding with the amount of experiencethe nurse may have with using the device.
However there was a lowerunderstanding level when it came to the principles of the pulse oximeter and asa final conclusion came to the understanding that experience is key inunderstanding the proper use and function in when and how to use a pulseoximetry device and the principles and concepts that go with it.
