N.B.: In your exam.: Chest case → blue → CO2 narcosis →Renal Failure. Abdomen case → yellowish → hepatic encephalopathy → Liver Failure 2. Vital Signs: ((Puullssee+BP+RR+TTeemppeerraattuurree)) 2. Vital Signs: P +BP+RR+ m a) Pulse: Rate: using your watch. If regular→ 15 seconds then x 4. If irregular or bradycardia→ complete minute. N.B: Pulse deficit= apical pulse ( – )باىسماعتradial pulse ()باىُد If < 10 → occasional. If > 10 → marked. SAN rate = 150 impulse/min. Parasympathetic system takes the upper hand, so normal HR: 60-100 beat/min Bradycardia < 60 Tachycardia > 100 Sinus bradycardia (SAN): 50-60 Sinus tachycardia (SAN): 100-150 Escape junctional or nodal (AVN): 30-50 Paroxysmal (not SAN)> 150 أٌ وقطت تقىي فترة ثم ٍتختف Ventricular. Supraventricular. Heart block 20-30 Rapid AF. Complete heart block with escape idioventricular rhythm Rhythm: Regular Irregular: Regular irregularity Irregular irregularity Due to monofocal premature Occasional Marked beats (extrasystoles) Pulse deficit < 10 >10 In digitalis toxicity You can count 4 Can’t successive regular beats E.g.: Pulsus Bigeminus e.g.: Multifocal premature Rapid AF beats (multifocal Pulsus Trigeminus extrasystoles) Volume: Pulse pressure= systolic Pressure – Diastolic Pressure Normally 30-50 mmHg. Big Pulse volume > 50 mmHg Small Pulse Volume < 30 mmHg. Causes of Big Pulse Volume: 1. ↑↑↑ systolic /↑diastolic: Systemic hypertension. Clinical medicine – General Examination 3 2. ↑↑ systolic / normal diastolic: d. Anemia a. Thyrotoxicosis. 4. Normal systolic /↓↓↓ diastolic: b. Aortic atherosclerosis. a. PDA 3. ↑↑↑ systolic /↓↓↓ diastolic: b. A-V fistula a. AR c. Pregnancy b. PDA d. VD therapy c. Severe bradycardia with e. Beri-Beri complete HB. f. Paget’s disease N.B.: All of the above are causes of hyper-dynamic circulation except AR and systemic hypertension. Causes of small pulse volume: 2. ↓ Pumping: 1. ↓ Filling: Cardiomyopathy Constrictive pericarditis Myocarditis Pericardial effusion Myocardial Infarction Severe tachycardia 3. Obstruction: Hypo-volemia Any valve stenosis (MS, TS, AS, PS). Irregular Pulse Volume: (In irregular rhythm) Pulsus alternans( :)وحدة قىَت واألخري ضعُفتin severe LVF, the diseased fibres have longer REFRACTORY period, so: o An impulse stimulates the normal fibres only →weak contraction. o The next impulse stimulate normal + diseased fibres → stronger contraction. Pulsus Paradoxicus( :)تختفٍ مع اىىفسcauses: o COPD o Pericardial effusion inspiration o Constrictive pericarditis. Normally, with inspiration: o Lung is congested with blood o ↑↑ VR to right sided heart o ↓↓ Blood reaching left side. o ↓ C.O. o ↓ Pulse volume. Pulsus paradoxicus is an exaggeration of the normal criteria: The above causes affect the relaxation of R.V. more than LV due to thinner wall, so with inspiration: Lung congestion More ↓ blood reaching LV. More ↓ CO. More ↓ pulse volume. Character: when you describe character, you should comment on 3 components: volume of pulse+rate of expansion (upstroke)+rate of collapse (downstroke). E.g.: Water hummer pulse (in AR): big volume+sudden expansion+sudden collapse. Plateau pulse (in AS):small volume, slow rate of expansion+slow rate of collapse. Equality ح ّ اىىبض عيً اىُدَه بعدما تخٍّ اىعَان َرفع َدَه مأوه َدعى ي س Causes of inequality: Clinical medicine – General Examination 4 Outside wall: cervical rib, Pancoast tumor (apical bronchogenic carcinoma), saccular aneurysm of aorta. Wall: dissecting aneurysm, Aortic coarctation. Lumen: thrombus, embolism. N.B.: radio-femoral lag: due to abdominal Aorta narrowing: Dissecting aneurysm Coarctation Thrombus Arterial wall condition: Normally: not felt. Cord-like: → Monckburg medial calcinosis (in media)/ midium arteries. Atherosclerosis (subintimal) / big arteries, not radial. Grape-like: polyarteritis nodosa. Peripheral pulsations (sound, murmur, thrill): Arteries: Carotid, Axillary, Brachial, Ulnar, Radial, Femoral, Popliteal, Posterior Tibial, Dorsalis Pedis. Rule: avoid thumb except in big arteries. Your comment: Absent Peripheral pulsations. Present: Sound: Pistol shot Murmur: Droisier sign Carotid shudder. Palpation of radial artery: a. By tips of middle 3 fingers. b. Against lower end of radius. c. Using moderate compression. d. Wrist should be pronated and supported by thumb or palm. b) Blood Pressure: measured: a. Directly: by catheter. b. Indirectly: Palpatory and auscultatory. KROTOKOV Sounds: I. Clear fine taps II. Murmurs III. Clear strong taps IV. Murmur (3-4 mmHg). V. Silence. Diastolic BP: I. Direct: gives pressure of phase 4. i.e. when sound starts to fade. II. Indirect: Palpatory: not used for DBP. Auscultatory: In most cases: DBP = phase 4 i.e. when sound disappears. In case of: children, AR, Hyper-dynamic circulation → DBP=beginning of phase 4, as there is prolonged phase 4. Management of Auscultatory gap: Clinical medicine – General Examination 5 I. Continue deflating cuff till zero to avoid DBP overestimation. II. Use palpatory method to avoid SBP underestimation. General Rules: In the room i.e. basal conditions: Avoid emotional stress for 5 min. Avoid exercise for 10 min. Avoid smoking for 15 min. Avoid eating for 30 min (2 hours in elderly). Evacuate the bladder. Reassure the patient to avoid WHITE COAT HYPERTENSION. In the patient: Sitting or lying, but prone position to measure L.L., and standing to diagnose postural hypertension. Remove clothes perfectly, but if tight completely take off. Elbow should be slightly flexed. Upper limb should be supported. In the sphygmomanometer: Mercury reservoir should be at the same horizontal level of heart and anti-cubital crease. Mercury column should be placed vertically. Rubber tubes should be medially. Avoid so tight and so loose. The suitable rubber bag should be used (lower limb, children and obese have special bags). Steps: 1. Palpatory: to detect SBP only and to avoid SBP underestimation in presence of auscultatory gap. 2. Auscultatory: Apply the cuff, not so tight or loose, with its lower edge above the anti-cubital crease by 3 cm with rubber tubes medially. Avoid herniation of rubber bag from the cuff. Inflate rapidly, above the level of pulse disappearance by 20-30 mmHg. Deflate slowly at 1 mmHg/sec. While placing chest piece over the brachial artery (medial to bicipital tendon) auscultate Krotokov’s sounds. SBP is the first. Diastolic BP was discussed before. Continue deflating till zero. Measuring BP in LL: Patient lies in prone position. Use larger cuff. Wrap it around mid-thigh, or around calf muscles if there is no large cuff. Place rubber tubes in midline of popliteal fossa. Auscultate popliteal artery in popliteal fossa, or posterior tibial if cuff tighted around calf muscles. Uses of sphygmomanometer: Diagnostic uses: 1. Measuring ABP: Normal ABP: 100-140/60-90 mmHg i. To diagnose hypertension (DBP): Mild 90-110 Clinical medicine – General Examination 6 Moderate 110-120 Severe 120-130 Malignant > 130 (Encephalopathy, Retinopathy, Papilledema, acute pulmonary edema). Types (causes): Essential (1ry) Secondary (renal, endocrinal, multi-factorial). ii. To diagnose hypotension: SBP < 100 mmHg. Causes: a. Over-dosage of anti-hypertensive b. Shock (SBP < 70 mmHg → cold limbs). c. Addison’s disease: never SBP > 110 mmHg. d. Postural hypotension: SBP during standing < during flat by > 20 mmHg. iii. To diagnose unequal pressure on both sides: Right > left, or left > right by 10 mmHg. Same causes of unequal pulse. iv. Compare UL and LL pressures: Normally by direct method UL > LL as closer to heart. By indirect method, LL > UL due to stronger muscle tone (20 mmHg). If LL > UL by > 20 mmHg → mild AR, > 40 mmHg → moderate AR, >60 mmHg → severe AR. If UL > LL → same cause of radio-femoral lag. v. To detect pulse pressure: Normally 30-50 mmHg. If < 30 (causes of small pulse volume). If > 50 (causes of big pulse volume). In AR pulse pressure > 60 and diastolic < 60 mmHg. 2. Hiss test: to diagnose Idiopathic thrombo-cytopenic purpura. Elevate cuff pressure between systolic and diastolic. Wait for 5 minutes. Remove the cuff: if ≥ 5 petichial hemorrhage in an area of 5 cm diameter → ↓↓ platelets. 3. Walker’s test: to diagnose Myesthenia Gravis. 4. Treasseant test: elevate > SBP → carpo-pedal spasm → latent tetany (Ca+2: 7-9 mg%, normally 9-11 mg %). 5. Lown berg test: to diagnose DVT. Apply the cuff on calf muscle and elevate pressure → the patient shout. 6. Diagnose Pulsus alternans: By auscultation: false impression of bradycardia. To diagnose, stop at SBP then deflate → sudden doubling of Krotokov’s sounds. 7. Diagnose pulsus paradoxicus: While measuring BP, Krotokov’s sounds will disappear at a given cuff pressure during inspiration. Deflate in steps until Krotokov’s sound is heard all through the respiratory cycle. This = SBP at weak beats. If this < expiratory SBP by > 10 mmHg → Pulsus paradoxicus.

Systolic thrill: AR =carotid shudder AS + thrill at base of heart Carotid artery aneurysm or stenosis or throbus. o Neck Veins: Introduction: Any vein is: Capacitant: its capacity > its blood content (1/10), so blood accumulates in its dependent lower parts more than upper parts, so distension of the lower part > the upper. Collapsible: collapsed upper part due to decreased V.R. Distensible: in lower part due to effect of gravity. Right IJV EJV Deep to sternomastoid Superficial to sternomastoid Does not pierce deep fascia Pierces the deep fascia Has no valves Has valves In direct continuity with SVC Makes an angle with SVC Examination of Neck Veins: Pressure: N.B.: Distance from angle of Lewis to center of right atrium = 5 cm. JVP: it’s the vertical distance in cms between angle of Lewis (zero level) and upper level of distension or pulsation of IJV. Normally: 0-3 cm water or blood. CVP=JVP+5. Normally = 5-8 cm blood. How to measure the pressure? 1. Ask the patient to lie in 45° (starting position). 2. Ask him to lie in an angle between 30°-90° (according to the case) that makes the upper level of distension or pulsation obvious. 3. Keep patient’s head supported and looking forwards. 4. Place the ruler vertically with its zero at angle of Lewis level or at clavicle if he’s in 45°. 5. Determine the JVP. 6.
