Pulse profile of the participant of the study

Pulse Oximetry has a primary
use that is mainly used in many different types of hospital environments and is
used as a non-invasive method of attaining blood oxygen saturation also known
as (SpO2) in patients. To find the amount of oxygen saturation the devise compares
and contrast the different wavelengths of light that is emitted from the pulse
oximeter and then compares the light that was absorbed and then transcribing it
into parameters giving us the percentage of oxygen saturation for a given
patient. 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 inadequate specifically
aimed towards nurses.            

            The methods used during this experiment was a type of
cross sectional and multicenter study which 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 recognize
or interpret the data can lead to potential misunderstanding of the relevant
data and lead to a misdiagnosis and can potentially 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 requiring
a minimum of a year of working in a clinical or health care 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 the data on the
profile of the participant of the study including age, the number of years worked,
their level of 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 more in-depth
understanding of the level of understanding that nurses would have while using pulse
oximetry on patients. 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 broader knowledge based 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 a defining key in the process of understanding
the proper use and function when and how to use a pulse oximetry device and the
principles and concepts that go with it.
