Q

How does a DA obtain a patient’s respiration?

A
  • By counting the number of breaths (chest rising and falling) a patient takes in a time frame

*Patients usually change their breathing pattern when they know that their breaths are being monitored
- count a person’s respirations while your fingers are still positioned on the wrist as if taking the pulse

Q

Temperature

A

A measurement of how hot or cold the internal body is
- associated with the metabolism of the body
- temperature can vary throughout the day, but illness can cause a person’s body temperature to elevate

20
Q

Thermometer

A

The instrument used to measure body temperature

21
Q

What are the different types of thermometers?

A

1) Digital
- battery operated, a timing system shows a digital reading after 30 seconds
- a disposable sheath slides over the probe before insertion

2) Tympanic
- an infrared signal is bounced off the eardrum and an accurate reading is provided within 2 seconds

3) Temporal scanner
- uses surface temperature of artery of forehead

4) Glass
- banned the use of mercury thermometers because of health hazards

22
Q

Where is temperature commonly measured?

A

1) Orally - under the tongue
2) Tympanic - inside ear
3) Axillary - under arm
4) Temporally - surface of forehead
5) Rectally - in rectum

23
Q

What is the normal temperature range for adults?

A

36.4 - 37.3 C

24
Q

What is the normal temperature range for children?

A

36.6 - 37.3 C

25
Q

What is the temperature difference between temporal and oral temperature?

A

Temperature taken with a temporal scanner is 0.3 - 0.6 C lower than oral temperature

26
Q

What could an unusual high blood pressure mean?

A
  • It could mean that the patient is anxious
  • It could also indicate a cardiovascular condition that could lead to a heart attack or stroke
27
Q

What could a low blood pressure indicate?

A

It could indicate that the patient is about to lose consciousness

28
Q

How often should a patient’s blood pressure be taken?

A

Should routinely be taken at the beginning of each appointment

  • if the patient is known to have a problem controlling high blood pressure, it should also be monitored pressures throughout any lengthy, invasive dental procedure
29
Q

How is blood pressure measured?

A
  • BP measures the force exerted by the blood against the walls of the arteries when the heart is contracting and again when the heart is in relaxation, between contractions
  • BP reflects the amount of work the heart has to do to pump blood throughout the body
  • There are 2 pressures of the heart:
    1) Systolic = reflects the amount of pressure it takes for the left ventricle of the heart to compress or push oxygenated blood out into the blood vessels

2) Diastolic = the heart muscle at rest when it is allowing the heart to take in blood to be oxygenated before the next contraction

30
Q

Systolic Pressure

A

Reflects the amount of pressure it takes for the left ventricle of the heart to compress or push oxygenated blood out into the blood vessels

Top number of the bp reading
- example 120/80 mmHg
- 120 is the systolic pressure

31
Q

Diastolic Pressure

A

The heart muscle at rest when it is allowing the heart to take in blood to be oxygenated before the next contraction

Bottom number of the bp reading
- example 129/85 mmHg
- 85 is the diastolic pressure

32
Q

What is the unit of measurement for systolic and diastolic pressures?

A

Measured in millimeters of mercury (mm Hg) above atmospheric pressure

  • readings are always recorded with the systolic value over the diastolic value
33
Q

What is the normal blood pressure reading?

A

Systolic: Less than 120
Diastolic: Less than 80

34
Q

What is the reading for elevated blood pressure?

A

Systolic: 120 - 129
Diastolic: Less than 80

35
Q

What is the reading for high blood pressure (Hypertension) stage 1?

A

Systolic: 130 - 139
Diastolic: 80 - 89

36
Q

What is the reading for high blood pressure (Hypertension) stage 2?

A

Systolic: 140 - 179
Diastolic: 90 -109

37
Q

What is the reading for Hypertensive crisis?

A

Systolic: Higher than 180
Diastolic: Higher than 110

Consult your doctor immediately

38
Q

List the different types of blood pressure equipment

A

1) Manual Device
- the clinician applies the cuff, inflates it, and listens for Korotkoff sounds with a stethoscope

2) Semi-automatic
- the clinician applies the cuff and pushes a button to inflate and deflate the cuff
- the device takes the reading

3) Fully automated
- the clinician applies the cuff and pushes a button to inflate and deflate the cuff
- the device can be programmed to obtain multiple BP measurements at specific time intervals and averages the measurements

39
Q

Sphygmomanometer

A

Manual BP equipment
- includes BP cuff and meter
- cuff is a cloth wrap that holds an inflatable rubber bladder
- rubber bulb is attached to the cuff with rubber tubing

40
Q

Proper cuff fit

A
  • The cuff’s air bladder should encircle 75-100% of the patient’s arm (it should not wrap around itself)
  • The width of the cuff should be at least 40-50% of the patient’s upper arm circumference
  • The cuff should be placed on a bare arm
  • Position the middle of the bladder of the cuff over the brachial artery (use the arrow on the cuff to guide you)
  • Position the patient’s arm so that the cuff is at heart level
  • The cuff should be snug at the top and bottom edges
41
Q

What are the 5 phases of Korotkoff sounds that occur during deflation of the blood pressure cuff?

A

1) Phase 1: Blood is beginning to flow back into the artery and can be heard as a sharp tapping sound
- this is the systolic bp reading

2) Phase 2: The cuff is deflate slowly, with blood flowing. A swishing sound may be heard. This sound is softened and becomes prolonged into a murmur

3) Phase 3: A large amount of blood is flowing into the artery. A distinct, sharp tapping sound returns and continues rhythmically

4) Phase 4: Blood is flowing easily and the sound changes to a soft tapping, This sound becomes distinctly muffled and fainter

5) Phase 5: At this point, the artery is fully open and the sound disappears.
- this is the diastolic bp reading

42
Q

How long would you have to wait to take another blood pressure reading if situations may arise?

A

Minimum of 10 minutes before obtaining another ready
- if taken too soon, the reading may be incorrect

For SAIT, wait for 5 minutes before taking another reading

43
Q

What are some medical considerations for blood pressure?

A
  • The stress and anxiety of a dental procedure could possibly elevate a patient’s bp
  • many drugs have adverse effects that can interfere with dental treatment
  • A patient who has been diagnosed with hypertension should be under the care of a physician during a treatment regimen
44
Q

How to take a blood pressure?

A
  • Seat the patient in an upright position that supports their back and feet
  • It is best to allow the patient to sit quietly for a few minutes (3-5) prior to taking bp
  • Ask the patient to keep their legs uncrossed before and during the measurement
  • Support the patient’s arm so that the cuff is positioned at heart level
  • The patient’s palm should be facing up and should be opened and relaxed
  • Neither you nor the patient should talk during the measurement
45
Q

Why are manual blood pressure devices less reliable?

A
  • Fragile
  • Require frequent calibration
  • More subject to human error due to the need of manual inflate/deflate of cuff and manually listening for Korotkoff sounds
46
Q

How is blood pressure documented in a patient’s record?

A

Record the systolic and diastolic bp
- note which arm was used
- note the type of device used

Example:
120/80 mmHg, left arm, automated device
