What is the ‘Normal’ range for systolic and diastolic blood pressure in adults?
Ideal - 120/80mmHg
Systolic only counted on NEWS 2 - Value of 111-219 doesnt score on the scale.
NHS health check - 90/60mmHg to 140/90mmHg is ‘Normal’.
Define blood pressure, including systolic and diastolic.
Blood pressure is the force exerted by the blood against the arterial vessel walls. It is measured in mmHg and is presented in two values;
- Systolic is the maximum pressure exerted on the vessel wall, during ventricular contraction.
- Diastolic is the resting pressure, exerted on the walls when the ventricles are not contracting.
State three signs of hypertension.
(Increased BP : I.e. 140/90)
- Arrhythmia (irregular heart beat)
- Headaches
- Chest pain
- Vision problems
What are the risks of hypertension.
Damaged and narrow arteries, decreasing the flow.
Increased risk of a stroke, aneurysm, coronary artery disease or eye damage.
Enlarged left heart.
State three signs of hypotension.
(Low blood pressure: I.e. 90/60)
- Blurred vision
- Fainting
- Dizziness
- Increased falls
What is the ‘Normal’ range for heart rate in adults.
51 - 90 bpm scores 0 on NEWS 2.
> 100bpm increased HR = Tachycardic
< 50bpm decreased HR = Brachycardic
(Athletes and the elderly can have a low HR as their ‘Norm’.)
Define Tachycardia.
An abnormally rapid HR (>100bpm)
Define Brachycardia.
Abnormally slow HR (<50bpm)
State five sites to palate a pulse.
- Radial (wrist)
- Brachial (inner crease of elbow)
- Carotid (neck)
- Femoral (groin)
- Popliteal (behind knee)
- Posterior tibial (ankle)
- Dorsalis pedis (big toe)
What is the ‘Normal’ range for body temperature I’m an adult.
36°c to 37.5°c
NEWS 2 doesn’t score with values between 36.1°c and 38°c.
Define hypothermia.
Abnormally low body temperature. (<35°c)
Define hyperthermia.
Abnormally high body temperature. (>38°c)
Results when the hypothalamic regulation of the body temperature is overwhelmed and an uncontrolled increase of body temperature exceeds the body’s ability to lose heat.
Define pyrexia.
Fever: abnormally high body temperature due to the presence of pyrogen (released during an infection).
Pyrexia is a type of hyperthermia.
Define apyrexia.
Absence or intermission (pause/break) from fever.
State three reasons why a patient may have pyrexia.
- Bactrial Infection
- Virus
- Certain medications (I.e. antibiotics)
- Vaccinations
- Sepsis
State three reasons why a patient has hypothermia and hyperthermia.
Hypothermia:
- Cold exposure forong periods of time
- Low blood sugar
- Shock
Hyperthermia:
- Heat stroke
- Reduced sweating due to medications (I.e. diuretics)
- Sepsis
What is the ‘Normal’ respiratory rate range in adults
12-20 (Key indicator)
Define bradypneoa
Abnormally slow breathing rate.
Define tachypnoea
Abnormally fast/rapid breathing rate.
State three reasons why a patient has bradypnoea and tachypnoea.
Bradypnoea:
- Due to medications (I.e. anethisia or morphine).
- Choking
- Loss of consciousness
- Brainstem injury
Tachypnoea:
- Shock
- Athsma attack
- COPD
Normal range of oxygen saturation in adults.
About or equal to 96% oxygen saturation.
COPD 88%-92% or about 93% on oxygen.
Define oxygen saturation.
The concentration of oxygen attached to haemoglobin.
Define hypoxia.
Abnormally low oxygen saturation.
Inadequate level of oxygen in the tissue.
Oxygen deficiency.
State three signs of hypoxia.
- Colour (cyanosis)
- Confusion
- Shortness of breath
