Clinical Observations; temperature and Blood Pressure Flashcards
Normal Temperature Range
No such thing as a ‘normal’ as depends on age, health and gender. But 35.8-37.5 is required for normal cellular metabolism
Different Ways Temperature can be Taken
- Orally (mouth)
- Axillary (under arm)
- Tympanic (ear) (one we do as paramedics)
How to use an Oral Tempadot (used on placements
- Wait 15 mins if person has had hot or cold drink
- Place under tongue (see diagram)
- Ask Patient to press tongue down
- Leave for a minute
- Remove, wait 10 seconds
- Read along to the last blue dot, which is their temperature
How to use an Auxiliary Tempadot (used on placements)
- Position high under armpit with good torso contact
- Remove after 3 minutes
- Read to last blue dot
How to use a Tympanic Membrane Thermometer (one we do)
- Clean equipment
- Let patient know what happening
- Put plastic cover onto probe
- Take the top of the ear (pinna pull it up and back to straighten ear canal
- Place in ear
- Push button and wait till beep, document number
- Dispose of cover, clean equipment
What temperature is classed as Pyrexia
38 degrees
What causes pyrexia?
infection, post trauma, hypervolaemia, neurological disturbances eg stroke
What Temperature is classed as Hypothermic?
<35 degrees
What causes Hypothermia?
old age, hypothyroidism, post immersion, liver failure, alcoholism
Why do we take a BP?
- Determine if enough pressure to circulate blood + perfuse tissues
- Act as baseline to compare previous readings/patient knowledge
- Establish trend
- Monitor response to treatment
Things that Effect BP
Age, exercise, stress, emotions, weight, race
What is Hypertension
When blood pressure is too high
What is Hypotension
When blood pressure is too low
What causes Hypertension?
age, pain, stress, acute, long-term conditions
What causes Hypotension?
postural hypotension, shock hypovolaemia
What is blood pressure and what is it measured in?
“The pressure the blood exerts against the inner walls of the blood vessels and the force that keeps blood circulating continuously even between heart beats.” BP is measured in millimetres of mercury (mmHg)
What is Systolic Pressure?
the maximum pressure exerted one the vessel wall during left ventricular contraction
What is Diastolic Pressure?
the resting pressure that the blood exerts between ventricular contractions
What is Pulse Pressure?
the difference between the systolic pressure and the diastolic pressure
What are we doing when we take a BP?
Using the brachial artery, we stop blood flow and listen to its return into the vessel by inflating then deflating
Patient Prep for Blood Pressure
- Has the patient had a BP before?
- Are they resting/comfortable?
- Upper arm should be at heart level
- Remove tight clothing
Steps to Taking a BP Reading
- Locate the brachial artery
- Put on cuff, placing arrow onto artery just found
- Locate radial artery
- Inflate till you no longer feel the radial pulse
- Note pressure reading
- Deflate the cuff
- Place stethoscope in bridge of arm to the side of the brachial artery
- Inflate 20 above previous reading
- Note the numbers in which the ‘tapping’ sounds starts (systolic) to when they stop (diastolic)
