Basic Monitors Flashcards
What #s = HYPERtension?
HTN
> 140/90
What #s = HYPOtension?
hTN
<90/60
hypOtension = lOw BP
What is the equation for mean arterial P?
(2 * Diastolic BP) + Systolic BP
_______________________
3
Does systolic or diastolic # come 1st in BP reading?
systolic
(systolic
_____
diastolic)
What is a normal value for mean arterial P?
70-100 mmHg
What is the equation for pulse P?
Pulse P = systolic - diastolic
What is a normal pulse P?
30-40 mmHg
50% systolic BP = wide BP
What are the consequences of HTN? (hypertension)
- possible MI (heart attack)-puts strain on heart
2. possible stroke
What are the consequences of hTN? (hypotension)
↓ tissue perfusion so could cause
- stoke
- MI
- renal failure
What is hypovolemia?
↓ volume of circulating blood
What is hypervolemia?
too much fluid in blood
What is a normal HR/EKG?
60-100
What HR is considered tachycardic?
Tachycardia (faster than normal HR @ rest)
>100
What HR is considered bradycardic?
Bradycardia (slower than normal HR @ rest)
<100
What is a normal pulse ox reading?
93-98%
What is EtCO2?
amount of CO2 breathed out
What is a normal EtCO2 reading?
35-45 mmHg
What 2 things does capnography reveal?
- EtCO2
2. respiratory rate (RR)
What is a normal respiratory rate if breathing on their own? If on ventilator?
Spontaneously breathing = 12-20 breaths/min
On ventilator = 8-12 breaths/min
What is normal body temp?
36-38°C
What happens to RR if pt in pain?
RR increases
What happens to RR if pt has pain relief?
RR decreases
What does it mean if a pt is hypoxic?
pt not getting enough O2
