3. Chapter 9 2 Vital Signs most important measurements you will obtain when you evaluate or assess a client’s condition.

4. Copyright © The McGraw-Hill Companies, Inc. Chapter 9 3 Temperature Body temperature (T) is one of the first assessments done. Temperature Ranges – Normal adult temperature is 98.6ºF, or 37ºC. – Normal range can be from 96.8ºF to 100.4ºF, or 36ºC to 38ºC.

5. Copyright © The McGraw-Hill Companies, Inc. Chapter 9 4 Temperatures can vary due to: Time of day. Allergic reaction. Illness. Stress. Exposure to heat or cold.

6. Copyright © The McGraw-Hill Companies, Inc. Chapter 9 5 Temperature Sites Oral – within the mouth or under the tongue. Axillary – in the armpit. Tympanic – in the ear canal. Rectal – through the anus, in the rectum. Other sites include on the skin or in the blood.

10. Copyright © The McGraw-Hill Companies, Inc. Chapter 9 9 Pulse Rhythm – the pattern of the heartbeats. – Measure for one for minute if irregular. – When documenting pulse rhythm, record as regular or irregular. Click Pictures for Sounds RhythmRegular Irregular

11. Copyright © The McGraw-Hill Companies, Inc. Chapter 9 10 Respiration Respiration (R) is the act of breathing. Respiratory Rate (RR) – Observe the client’s chest movement upward and outward for a complete minute. – Children under 7 years of age use abdominal breathing. – Auscultation with a stethoscope may be necessary on clients who are aware that you are counting their respiratory rate.

12. Copyright © The McGraw-Hill Companies, Inc. Chapter 9 11 Characteristics of Respiration Rate of Respiration – the number of breaths per minute. – Normal range is 12 to 20 breaths per minute for an adult. – Rate will vary with age and size of client. An increased respiratory rate is called hyperventilation. A decrease in respiratory rate and depth is called hypoventilation.

13. Copyright © The McGraw-Hill Companies, Inc. Chapter 9 12 Rhythm of Respiration – should be regular. Quality of Respiration – Can be shallow or deep.

14. Copyright © The McGraw-Hill Companies, Inc. Chapter 9 13 Blood Pressure Blood pressure (BP) is the pressure or tension exerted on the arterial walls as blood pulsates through them. Systolic blood pressure (SBP) – pressure exerted on the arteries during the contraction phase of the heartbeat. Diastolic blood pressure (DBP) – the resting pressure on the arteries as the heart relaxes between contractions.

15. Copyright © The McGraw-Hill Companies, Inc. Chapter 9 14 Blood Pressure (cont.) Expected Blood Pressure Values – Expected SBP – 100 to 140 mm Hg. – Expected DBP – 60 to 90 mm Hg. – Hypotension – when the blood pressure drops below expected levels. – Hypertension – high blood pressure. – Prehypertension – classified by the American Heart Association as SBP 120 to 139 mm Hg or DBP 80 to 89 mm Hg.

33. Copyright © The McGraw-Hill Companies, Inc. Taking a Pulse The radial pulse is used for routine vital signs It is felt by placing the first two or three fingers of one hand against the radial artery. Count the pulse for one minute.

34. Copyright © The McGraw-Hill Companies, Inc. Respirations Process of breathing air into (inhalation) and out of (exhalation) the lungs. (Respiration Rate) Oxygen enters the lungs during inhalation. Carbon dioxide leaves the lungs during exhalation. The chest rises during inhalation and falls during exhalation. Normal rate 12-20 breaths per minute

35. Copyright © The McGraw-Hill Companies, Inc. Assessing Respiration Respirations is measured when the person is at rest. Rate may change is patient is aware that it is being counted. To prevent this, count respirations right after taking a pulse. Keep your fingers or stethoscope over the pulse site. To count respirations, watch the chest rise and fall.

36. Copyright © The McGraw-Hill Companies, Inc. Assessing Respiration Character and quality of respirations is also assessed: – Deep (diaphragmatic breathing) – Shallow (hypopnea) – Labored or difficult ( dyspnea) – Noises – wheezing, stertorous (a heavy, snoring type of sound) – Moist or rattling sounds Apnea – absence of respirations Cheyne-Stokes – periods of dyspnea followed by periods of apnea; often noted in the dying patient Rales – bubbling or noisy sounds caused by fluids or mucus in the air passages

43. Copyright © The McGraw-Hill Companies, Inc. Blood Pressure Measure of the pressure blood exerts on the walls of arteries Blood pressure is controlled by: – The force of heart contractions weakened heart  drop in BP – The amount of blood pumped with each heartbeat loss of blood  drop in BP – How easily the blood flows through the blood vessels Narrowing of vessels  increase in BP Dilatation of vessels  decrease in BP

44. Copyright © The McGraw-Hill Companies, Inc. Factors that Affect Blood Pressure Factors that  blood pressure Excitement, anxiety, nervous tension Stimulant drugs Exercise and eating Factors that  blood pressure Rest or sleep Depressant drugs Shock Excessive loss of blood

45. Copyright © The McGraw-Hill Companies, Inc. Measuring BP A sphygmomanometer is used to measure BP – Aneroid – has a round dial and needle – Mercury – has a column of mercury – Electronic – automated device BP is measured in millimeters (mm) of mercury (Hg). The systolic pressure is recorded over the diastolic pressure.

46. Copyright © The McGraw-Hill Companies, Inc. Contraindications for Taking BP Measurement of BP at the brachial artery is a generally benign procedure. However, there are some circumstances in which obtaining readings from a particular arm my not be appropriate: -Presence of an arterial-venous shunt -Recent axillary node dissection -Any deformity or surgical history that interferes with proper access or blood blow to the upper arm. If these relative contraindications are present, BP should be assessed in the opposite arm. There may also be pre-existing conditions that can interfere with the accuracy or interpretation of readings, such as aortic coarctation, arterial-venous malformation, occlusive arterial dz, or the presence of an antecubital bruit. If neither arm can be used, then measurement of blood pressure in a leg may be indicated.

47. Copyright © The McGraw-Hill Companies, Inc. Normal Range of Blood Pressure Systolic: Pressure on the walls of arteries when the heart is contracting. Normal range – less than 120 mm Hg Diastolic: Constant pressure when heart is at rest Normal range – less than 80 mm Hg Hypertension—BP that remains above a systolic of 140 mm Hg or a diastolic of 90 mm Hg Hypotension—Systolic below 90 mm Hg and/or a diastolic below60 mm Hg

48. Copyright © The McGraw-Hill Companies, Inc. Measuring Height and Weight Used to determine if patient is underweight or overweight Height and weight charts are used as averages Weight greater or less than 20% considered normal BMI or Body Mass Index a statistical measure of body weight based on a person's weight and height. BMI from 18.5 to 24.9 is considered normal

50. Measuring Height and Weight General Guidelines: Use the same scale every day Make sure the scale is balanced before use Weigh the patient at the same time each day Remove jacket, robe, and shoes before weighing OBSERVE SAFETY PRECAUTIONS! Prevent injury from falls and the protruding height lever. Some people are weight conscious. Make only positive comments when weighing patients

51. Copyright © The McGraw-Hill Companies, Inc. Types of Scales Clinical scales contain a balance beam and measuring rod. Bed scales or chair scales are used for patients unable to stand Infant scales come in balanced, aneroid, or digital. – When weighing an…keep slightly over but not touching the infant. – A tape measure is used to measure infant height.

52. Copyright © The McGraw-Hill Companies, Inc. Converting Weight to Metric Measurement To convert multiply by: Grams to ounces 0.0353 Grams to pounds 0.0022 Kilograms to pounds 2.2046 Ounces to grams 28.35 Pounds to grams 453.592 Pounds to Kilograms 0.4536

53. Copyright © The McGraw-Hill Companies, Inc. Converting Height Converting inches to centimeters is simple…just take the number of inches and multiply it by 2.54. So for example, 8 inches would be 20.3 cm (8 x 2.54= 20.3) 20.3 / 2.54 = 7.99 1foot = 12 inches
