25
Thrombophlebitis/thrombosis
Blood clot (thrombus) formed in the vein
26
Embolus
-Particle or mass t moves through blood vessels until it reaches a vessel that is too small to let is pass (Lodges & causes obstruction of blood flow) -Can cause ischemia and/or infarction
27
Pulse Pressure
-Represents the force that the heart generates each time it contracts -Difference between systolic and diastolic pressures
28
Normal Pulse Pressure
Usually within the range of 30-40mmhg
29
Abnormal Pulse Pressure Causes
-Benign causes include vigorous exercise -Pathological causes: atherosclerosis, and aortic regurgitation
30
Hypertentive Crisis
-Acute, severe rise in blood pressure -May or may not have organ dysfunction
31
Urgency Hypertension
>180/>120 w/o organ damage -Need evaluation including medication
32
Emergency hypertension
>180/>120 mmHg with organ damage -Immediate emergency
33
Normal Pulse Pressure Description
-Pressure of the pulse: Normal -Contour: Smooth and rounded
34
Small/Weak Pulse
-Pressure of the pulse: Diminished -Contour: Upstroke slow, peak prolong
35
Large/Bounding Pulse
-Pressure of the pulse: Increased -Contour: Rapid rise and fall, peak brief
36
Bisferiens pulse
Increased rate with double peak
37
Pulsus Alternans
Regular rhythm but the beats alternate
38
Paradoxial Pulse
-Opposite of what normally happens -Inspiration: Amplitude decreases -Expiration: Increases
39
Pulsus bigminus
Irregular rhythm with 2 beats close together followed by a pulse
40
Inspection of hands and nails
Cyanosis, nail clubbing, splinter hemorrhages, palmar erythema, nicotine staining
41
Cyanosis-Related Disorders
Heart failure, COPD, Pulmonary embolism
42
Nail clubbing
Associated with cardiopulmonary disease
43
Splinter hemorrhages
Thin, red to reddish brown lines of blood under the nails that can occur with endocarditis, vasculitis or nail trauma
44
Endocarditis
Infection of heart valves
45
Vasculitis
Vessel damage from swelling of blood vessels
46
Palmar erythema
Portal hypertension
47
Nicotine Staining
Associated with smoking
48
Internal jugular vein
Lower neck in triangle formed the two heads of the SCM and clavicle
49
Jugular venous pressure (JVP) Measurement
-Patient is supine. Elevate trunk to 45 degrees. Tilt chin up &slightly away. • Use tangential light to find internal jugular vein pulsations. This is the top of the venous column of blood. • Extend a card/ tongue depressor horizontally from the pulsation while holding a ruler vertically from the sternal angle. • The card and ruler should intersect. Measure the vertical distance.
50
Interpretation of JVP
Normal: less than 2-3cm (<1 inch) Abnormal: Above 3cm (more than 1 inch), absent
51
Elevated JVP means
-Classic sign of venous hypertension -Right sided heart failure -Tricuspid stenosis
52
Observe the precordial area for:
-Asymmetry/deformities -Difficulty breathing -Heaves (lifting of chest) or pulsations (location, size, contour, & timing)
53
Apical Pulse (Apex beat)
• Look for Located at Point of Maximum Impulse (PMI) at 5th ICP, midclavicular line • Ask patient to exhale slowly & hold breath at end of expiration • If unable to visualize, have patient roll 45° toward left lateral decubitus position • Exhale completely while shining penlight across region. • Look for size, intensity, location
54
Apex Beat
If observed, suggests cardiomegaly, such as left ventricular hypertrophy
55
Orthopnea
Difficulty breathing while supine; Consider pulmonary edema due to left ventricular failure
56
Sternoclavicular pulsation
May suggest dissecting aneurysm of ascending aorta.
57
Epigastric & subxiphoid pulsations
Usually abnormal; Related to right ventricular hypertrophy or abdominal aortic aneurysm
58
Palpation: Apical Impulse (apex beat)
• Used fingertips • Palpate at Point of Maximal Impulse: Location: 5th intercostal space, midclavicular line • Normal: 2-3 cm diameter • Abnormal: >3 cm diameter: left ventricular hypertrophy (Laterally displaced: indicates cardiomegaly)
59
Palpation: Thrills interpretation
-Normal: No vibration -Abnormal: Individual locations can indicate different conditions; Aortic valve: ascending aortic aneurysm/Tricuspid valve: Left atrial enlargement
60
Percussion Interpretations (Heart)
Normal: dullness from sternum to approximately 6cm lateral to the left of the sternum Abnormal: If large, may suggest hypertrophy
61
Auscultation of Heart: Principles
-Diaphragm: High pitched sounds -Bell: Low pitched sounds
62
Heart Sounds: Types
-Normal: S1 (Lub) and S2 (Dub) -Extra 3rd sounds: S3 and S4 gallop -Heart murmur -Split sounds -Systolic: Interval between S1 and S2 -Diastolic: Interval between S2 and S1
63
S1 Lub
-Closure of mitral & tricuspid valves -Blood flows from atrium to ventricle -Start of systole -Best heard with bell -Ideal to hear sound over mitral
64
S2 Dub
-Closure of aortic and pulmonary valves -Blood flows from ventricles to body & lung -Best heard with diaphragm -Ideal listen at pulmonic
65
S2 physiological split
Best heard at pulmonic area with inspiration Use diaphragm (high pitched sound) Normal (90% have it)
