Vital signs review Flashcards
What are the vital signs
- heart rate
- o2 saturation
- respiratory rate
- pain
- blood pressure
- temperature
Why are vital signs important
to detect or monitor potential medical problems
What does body temp depend on
gender, menstruation, time of day, fluid intake, recent activity, and food
Average body temperature?
36.5 - 37.2 C
How can temperature be taken
Orally (mouth), Tympanic (ear), Rectal (Anus), temporal (skin), axillary (armpit)
Hyperthermia? Hypothermia?
Hyper- increased temperature (37.5–38.3 °C)
Hypo- decreased temperature (below 35)
Temperature during a fever + when is temperature the highest
38.5, during the evening
Temperatures we can take
Above 40 is life threatening (body)
41- brain death begins
45- near death
internal above 50- immediate death and rigid muscles
What is the pulse; what are you feeling?
Change in the diameter of the arteries that can be felt on the body’s surface following heart contractions
As the heart pushes blood through the arteries, the arteries expand and contract with the flow of the blood.
What does a pulse measure…HR..and..
HR, rhythm, and strength
Normal Heart Rate
60 to 100 beats per minute, average 70-72bpm
What can cause differences in HR
exercise, illness, injury, and emotions.
Females tend to have faster heart rates.. T/F
T; females above 12
Where can you take HR
carotid artery (neck); radial artery (wrist); brachial artery (elbow); femoral artery (groin); dorsalis pedis artery (foot) – for most people the easiest place to take the pulse and get a starting value is at the wrist (lease invasive)
Why would you never press both carotid arteries at the same time?
would cause a stroke; preventing blood from getting to Brain, cerebrovascular accident
Why would you not use your thumb while taking HR?
Your thumb has its own pulse
Why is RR done during HR?
So the patient can’t alter their regular breathing pattern
What can cause alterations?
(Temp)
Fever, illness, and other medical conditions
Adult avg RR
12-20
O2 saturation measures…?
Measure of the oxygen saturated hemoglobin relative to the total hemoglobin (saturated and unsaturated) in the blood
Acceptable Measures? Acceptable measure during covid
(O2 SAT)
Pre-Covid: 95-100
After/During Covid- 93+
What is O2 sat measured with
oximeter
The redder the blood…
Higher the O2 Sat
