Q

A

37 degrees Celsius (98.6 F)

28
Q

< 60bpm = bradycardia
^~ Difference between both is Pulse Pressure
~Radial artery is the most common site used to palpate the pulse
Pulsus Paradoxus- Significant decrease in pulse strength during spontaneous inspiration that can be quantified with a blood pressure cuff
Pulsus Alternans- Alternating succession between strong and weak pulses

29
Q

Respiratory rate

A

12-18 breathe/minute
~ Tachypnea- Rate > 20 breathes
~ Bradypnea- Rate < 10 breathes

30
Q

Arterial Blood Pressure
~ Force exerted by the heart against the systemic arteries as the blood moves through them

A

Arterial-Peak force exerted in the major arteries during contraction of the left ventricle
Diastolic-Force in the major arteries remaining after relaxation of ventricles
Hypertension- > 140/90
~Stage 1: 140-159/ 90-99
~stage 2: >160/ >100
~3Rd stage: pre-hypertension 120-139/80-89
Hypotension-
~ Systolic <90
~ Arterial pressure <65
~ Decrease in systolic pressure >40 from baseline
Shock- inadequate delivery of O2 and nutrients to the vital organs relative to their metabolic demand
Postural hypotension- Postural changes in a hypovolemic patient who often produces hypotension
Syncope- Fainting

31
Q

Jugular Venous Pressure (JVP)

A

~Estimated by determining how high the jugular vein extends above the level of the sternal angle
Kussmaul sign-When JVP increases during inhalation

32
Q

Jugular Venous Distension (JVD)

A

Present when the jugular vein is enlarged and can be seen more than 4cm above the sternal angle
~Chronic hypoxemia who develops right heart failure from hypoxemia-induced pulmonary hypertension
~ Left heart failure, Cardiac tamponade, tension pneumothoraxes
Lymphadenopathy-Enlarged lymph nodes

33

36
Q

Respiratory muscles

A

Can generate inspiratory pressures of 150cm H2O (112mm Hg)
Tracheal tugging-Downward movement of the thyroid cartilage toward the chest during inspiration in concert with the sternocleidomastoid muscle recruitment

37
Q

Abnormal Breathing Patterns

A

Cheyne Stokes- When RR and Vt gradually increase in intensity and then gradually decrease to complete apnea
Agonal breathing- Intermittent prolonged breathing
Apnea- No breathing
Apneustic breathing- Prolonged inspiratory pause at full inspiration typically lasting for 2-3 seconds
Asthmatic breathing- Prolonged exhalation with the recruitment of abdominal muscles
Biot respiration- Chaotic breathing pattern characterized by frequent irregularity in both rate and tidal volume that eventually deteriorates to agonal breathing and terminal apnea
Central neurogenic hyperventilation- Persistent hyperventilation

38
Q

Paradoxical breathing

A

~ Abdominal- abdominal wall moves inward on inspiration and outward on expiration
~ Chest- Part or all of the chest wall moves in with inhalation ad out with exhalation

39
Q

Fatigue vs. muscle weakness

A

~ Inability of contracting muscles to achieve a target pressure
~ Inability to achieve a target pressure in a rested muscle

40
Q

Respiratory Alternans

A

When the diaphragm and ribcage muscles alternately power breathing in an attempt to rest each muscle group

41
Q

Abdominal Paradox

A

Complete diaphragmatic fatigue, as the diaphragm is drawn upward into the thoracic cavity with each inspiratory effort of the rib cage muscles

42
Q

Palpation

A

touching chest wall to evaluate underlying structure and function
Vocal Fremitus- Vibrations created by vocal cords from speech
Tactile Fremitus- Vibrations felt on the chest wall
Subcutaneous Emphysema- Fine air bubbles collecting in subcutaneous tissues produce a crackling sound and sensation when palpated

43
Q

Percussion

46
Q

~Atelectasis, Fibrosis, pulmonary edema
Wheezes- (continuous) High or low-pitched quasi-musical sound
~Asthma, congestive heart failure
Stridor- (continuous) loud, high-pitched sound associated with upper airway obstruction and often heard without a stethoscope

A

A patient with heart disease who has S3 and S4

49
Q

Clubbing

A

Painless enlargement of the terminal phalanges of the fingers and toes associated with numerous cardiopulmonary and other diseases
~COPD

50
Q

Cyanosis

A

Peripheral- Poor perfusion of the extremities so that tissues extract more O2
Central- Mucosa or the torso are involved and may signal severe lung diseases
~Becomes visible when the amount of unsaturated hemoglobin in capillary blood when exceeds 5-6g/dL

51
Q

Capillary Refill

A

Pressing firmly on the patient’s fingernail until the nail bed is blanched, and then releasing the pressure
~ Normal refill time 3 sec or less
~ Poor output when exceeds 5 sec

52
