Peak expiratory flow rate (PEFR) measurement & explanation - OSCE Guide | UKMLA | CPSA
Summary
TLDRIn this medical consultation, Andrew, a medical student, introduces himself to Simon, a 24-year-old patient, and explains the process of taking a peak flow measurement to assess lung function. Simon is guided through the setup of the equipment, including inserting the mouthpiece and setting the dial to zero. He is then instructed on the proper technique for taking the measurement, which involves sitting straight, taking a deep breath, and exhaling forcefully. After demonstrating, Andrew has Simon perform the test, achieving a good score of 700, and notes the importance of recording the best of three readings in a peak flow diary.

Q & A
What is the purpose of the peak flow measurement mentioned in the script?
-The purpose of the peak flow measurement is to assess how well a person's asthma is controlled at the moment.
Who is conducting the peak flow measurement in the script?
-Andrew, a medical student, is conducting the peak flow measurement.
What is the name and age of the person undergoing the peak flow measurement?

What are the important aspects of setting up the peak flow meter equipment?
-The important aspects include ensuring the mouthpiece is inserted into the peak flow meter and setting the dial to zero.
What are the key points of the technique for taking a peak flow measurement?
-The key points are sitting up straight, taking a deep breath, sealing the lips around the mouthpiece, and breathing out as hard and fast as possible.
Why is it necessary to look at the reading on the peak flow meter?
-Looking at the reading on the peak flow meter is necessary to record the peak expiratory flow rate, which is an indicator of lung function.
What does Simon need to repeat back to Andrew to confirm his understanding of the procedure?
-Simon needs to repeat the steps for setting up the mouthpiece, setting the dial to zero, sitting up straight, taking a deep breath, and breathing out hard and fast.
What is the initial peak flow score Simon achieved in the script?
-Simon's initial peak flow score was 700.
How many readings are usually taken for a peak flow measurement?
-Typically, three readings are taken for a peak flow measurement.
What is done with the three peak flow readings taken?
-The best of the three readings is taken, and this value is recorded in the peak flow diary.
Why is it important to record the peak flow readings in a diary?
-Recording the peak flow readings in a diary helps track lung function over time and can assist in managing asthma more effectively.

Transcripts
good morning my name is Andrew and one
of the finally our medical students
going to just confirm your name and age
please I'm Simon and I'm 24 nice to meet
you Simon
today I've been asked to take something
called a peak flow measurement this will
just involve breathing out into this
peak flow meter on the table would that
be okay yeah that's fine it'll just help
us assess how well your Asmus controlled
at the moment okay
okay Simon in terms of setting up the
equipment the important aspects are to
ensure that the mouthpiece is inserted
into the peak flow meter and to ensure
that the dial is set to zero now that
you've got your equipment set up Simon
there's some important aspects of the
technique to remember these are to
ensure that you set up nice and straight
to take a nice deep breath in as far as
you can to ensure that your lips are
sealed around the mouthpiece and to
breathe out as hard and as fast as you
can okay okay I'm now going to
demonstrate
you then need to look at the reading you
get on the peak flow meter okay was that
all quite clear I think so yeah
brilliant would you like to just repeat
to me what you've learned so far
sure okay and so I need to put my own
mouthpiece in set the dial back to zero
and then sit up nice and straight and
then take a nice deep breath in as far
as I can and then breathe out as hard
and fast as I can as well that sounds
perfect to you okay it's not time for
you to have a go all right
that's a really good score of 700 to
finish we just need to take another two
readings we'll take the best of all
three readings and record it in your
peak flow diary okay thank you very much
