Vital Observations Flashcards
Patient observations are undertaken for the following three reasons…
1) they provide a baseline
2) they assist in the recognition of improving or deteriorating health
3) they assess the effectiveness of care
Why are observation charts important? (i.e. NEWS2)
The data plotted onto the chart can allow for trends and patterns to be seen - good and bad.
The abbreviations BD, TDS and QDS mean what?
BD - 2 times a day (every 12 hours)
TDS - 3 times a day (every 8 hours)
QDS - 4 times a day (every 6 hours)
What is the function of respiration?
To provide the tissues and cells of the body with sufficient oxygen to support aerobic metabolism and the removal of C02 (the waste product of metabolism)
Which vital observation is an early indicator of illness?
Respiratory Rate
What are the two classifications of respiration and what do they do?
External Respiration - the exchange of gases at alveolar and capillary level
Internal respiration - the metabolism of gases at a cellular level (where the body combines the oxygen with carbohydrates to create energy, resulting in C02 as a waste product)
Respiratory Rate is recorded in what form?
Breaths per minute (BPM)
What would you do to take a patients Respiratory Rate ?
Observe the chest rising (inspiration) and falling (expiration) over 60 seconds.
What is one breath counted as?
One breath is counted as one cycle of inspiration and expiration.
What three things are included when assessing a patients Respiratory Rate?
Rate, Depth and Pattern
What does ‘depth’ indicate when assessing respiratory rate?
Depth indicates the volume of air moving in and out of the lungs with each respiration.
What can a change in a respiratory pattern indicate?
It can indicate that there is a problem with the respiratory centre in the brain.
What other respiratory observations may a nurse use apart from RR (rate, depth and pattern)?
Look, listen and feel.
What does normal respiration sound like and what sounds could indicate respiratory distress?
Normal respiration = quiet
Respiratory distress = sounds such as grunting, snoring and gurgling.
What is chest asymmetry and what are the accessory muscles?
Chest asymmetry is when both sides of the chest do not take off at the same time.
Accessory muscles = anything that is NOT the diaphragm, external intercostal or scalene muscles (primary inspiration muscles).
What is cyanosis and what may it indicate?
Cyanosis refers to a bluish tinge/cast to a patients skin and mucus membrane (normally observed on fingers and lips).
It indicates low oxygen levels and is a late sign of respiratory deterioration.
What are the two levels of cyanosis?
Peripheral cyanosis (n the extremities and fingers), often seen in shock.
Central cyanosis (around the core, lips and tongue), indicates the patient is very ill and represents gross hypoxemia (low oxygen blood concentration)
When taking a patients respiratory rate they should ideally be _______.
Unaware - patient’s RR often changes when they are aware their breathing is being observed.
this can be achieved by taking a patients RR alongside other obs e.g. pulse
______ lips and _____ flaring can be another sign of respiratory distress / dysfunction.
Pursed lips and nasal flaring.
Assessing a patients level of a________ is also important as lack of a________ can indicate hypoxaemia.
Alertness.
What is a normal respiratory rate for an adult?
12 - 20 BPM
What is tachypnoea and what RR is it considered as?
Tachypnoea is known as hyperventilation and is a RR of >20 BPM.
What is bradypnoea and what RR is it considered as?
Bradypnoea is known as hypoventilation and is a RR of <12 BPM.
What is dyspnoea?
Dyspnoea is shortness of breath.
