Pulse would conclude that there is no complication when

Pulse Oximetry is used
mainly in many hospital environments and us used as a non-invasive method of
obtaining blood oxygen saturation or (SpO2) in patients. To find the amount of oxygen
saturation the devise uses and reads different wavelengths of light and then
compares the amount of light that was absorbed and then transcribing it into
calculations giving us the percentage of oxygen saturation. This came to be a
basic practice in the medical field as one did not have to analyze blood
samples, 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 type
therapy to make sure that the patient is receiving an adequate supply and is
not being hindered by asthma or chronic obstructive pulmonary disease. However by
looking at a pulse oximeter one would conclude that there is no complication
when managing the device and appears to be rather simple there are complexities
that go with the devise and understanding the readings. This lead to a
hypothesis that many other studies have shown that the knowledge based of
health care professionals relating to the use of pulse oximeters is insufficient
specifically aimed at nurses.           The
methods used were a type of cross sectional and multicenter study was conducted
in 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 use
and interpret the pulse oximeters results that are taken from a patient. Being
unable to accurately interpret the data can lead to potential miscommunications
and misdiagnosis and compromise the patient entirely. In the study 198 nurses
became participants including 90 coming from the intensive care unit, 22 came
from the department of anesthesiology and the final remaining nurses which made
up 86 came from the emergency department all having a minimum of a year of
working in a clinical setting. Those who did not meet the requirements were not
allowed to participate in the experiment. The form of the study was conducted
by a questionnaire that was turned in at the end of their shift. First part was
collecting 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 aimed
at 22 question that were specific to pulse oximetry.

            The results came as a satisfactory level of reliability
as scores for the knowledge based scored between 6 and 18 as the highest score being
22 and the median being 12. Scores for pulse oximetry functioning came to
average of 5 and conditions effecting its accuracy had a median of 6. The knowledge
based interpretation was varied by department as shown that the participants
that came from the emergency room and intensive care units scored higher that
of the anesthesiology department. For example in table 3 shows the first 11
questions of the questionnaire that the nurses would fill out at the end of
their shift. This table shows the number and percentage that received the
correct responses and not showing those that were incorrect. By look at this
table at first glance we can conclude from the first 11 questions that the intensive
care unit and the anesthesiology department scored the highest having each having
the highest percentage on 4 questions each then the other departments while the
emergency 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 departments
scored lower than 50 percent demonstrating their lack of knowledge based on the
question that was given as in question 3,4,5,7,8,9. This data for the first
half of the question does show strong knowledge based results of understanding the
principles or concepts of the question however it also shows a misunderstanding
of knowledge based questions as well. I believe to that experience with the
pulse oximeter gave way to a better understanding of how it worked. The end
result came to that only about 54% of the nurses had a limited amount of knowledge
concerning the uses and interpretation of pulse oximeters.

            This study was preformed to have a better understanding
of the level of knowledge that nurses would have on pulse oximetry. The final conclusion
came to that nurses have a satisfactory level of knowledge when relating to the
factors and conditions that may affect the pulse oximeters when being used which
can be estimated as having a better understanding with the amount of experience
the nurse may have with using the device. However there was a lower
understanding level when it came to the principles of the pulse oximeter and as
a final conclusion came to the understanding that experience is key in
understanding the proper use and function in when and how to use a pulse
oximetry device and the principles and concepts that go with it.
