Advanced cardiac life support or advanced cardiovascular life support (ACLS) refers to a set of clinical interventions for the urgent treatment of cardiac arrest, stroke and other life-threatening medical emergencies, as well as the knowledge and skills to deploy those interventions.
IT CREATES AWARENESS AMONG GENERAL PUBLIC REGARDING CPR A LIFE SAVING PROCEDURE. . IT ALSO HELPS PARA MEDICS & NURSING PERSONNEL TO ENHANCE THEIR KNOWLEDGE ABOUT & HELPS TO EDUCATOR TO TEACH THEIR STUDENTS ABOUT CPR.
Cardiac arrest, also known as cardiopulmonary arrest or circulatory arrest, is the end of normal circulation of the blood due to failure of the heart to contract effectively.
Also referred as a sudden cardiac arrest (SCA).
Cardiac arrest is a medical emergency that, in certain situations, is potentially reversible if treated early.
Unexpected cardiac arrest sometimes leads to death almost immediately; this is called sudden cardiac death (SCD).

MANAGEMENT OF ATRIOVENTRICULAR CONDUCTION BLOCK.pdfJim Jacob Roy
Cardiac conduction defects can occur due to various causes.
Atrioventricular conduction blocks ( AV blocks ) are classified into 3 types.
This document describes the acute management of AV block.
Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.
2. DEFINITION OF CARDIAC ARREST:
It is loss of cardiac function, breathing, and loss of
consciousness.
DIAGNOSIS OF CARDIAC ARREST: (TRIAD)
1) LOSS OF CONSCIOUSNESS
2) LOSS OF APICAL & CENTRAL PULSATIONS
3) APNEA
3. TYPES OF CARDIAC ARREST:
• ASYSTOLE (ISOELECTRIC LINE)
• Check that all leads are attached.
• Adrenaline 1 mg IV every 4 mins (2 cycles) (until a
shockable rhythm is achieved).
4. Ventricular fibrillation (VF)
• Bizarre irregular waveform.
• No recognizable QRS complexes.
• Random frequency and amplitude.
• Coarse / fine.
• Exclude artifact:
• movement
• electrical interference
5. Pulse less Ventricular tachycardia (VT)
• Broad bizarre-shaped complexes.
• Rapid rate: 120-250/min.
• Regular.
• Precordial thump: Rapid treatment of a witnessed and monitored
VF/VT cardiac arrest.
6. 4)PEA: pulseless electrical activity:
• Exclude / treat reversible causes.
• Adrenaline 1 mg IV every 4 mins (2 cycles) (until a
shockable rhythm is reached).
8. Causes of cardiac arrest (6 H & 4 T):
• Cardiac Tamponade.
• Tension pneumothorax.
• Thromboembolism (pulmonary, coronary).
• Toxicity (eg. digoxin, local anesthetics, TCA, insecticides).
9. • Cardiopulmonary resuscitation (CPR) is a
lifesaving technique useful in many
emergencies, including heart attack or near
drowning, in which someone's breathing or
heartbeat has stopped.
10.
11.
12. • Cardio Pulmonary Resuscitation is a
technique of basic life support for
oxygenating the brain and heart until
appropriate, definitive medical treatment
can restore normal heart and ventilatory
action.
13. • Cpr consists of the use of chest
compressions and artificial ventilation to
maintain circulatory flow and
oxygenation during cardiac arrest.
14. • To maintain an open and clear airway (A).
• To maintain breathing by external ventilation
(B).
• To maintain Blood circulation by external
cardiac massages (C).
• To save life of the Patient.
• To provide basic life support till medical and
advanced life support arrives.
15. • DIAGNOSIS OF CARDIO PULMONARY ARREST:
CARDIAC ARREST:
• Absence of pulse in major arteries (carotid or femoral in older
children and femoral or brachial in infants as carotid is
difficult to palpate due to short neck.)
• Absence of Heart Sounds on Auscultation.
• Asystole/ventricular fibrillation on ECG.
16. • RESPIRATORY ARREST:
Absence Of Respiration On Looking (Absent
Chest Movement), Listening (Absent Air Flow On
Bringing Ears In Front Of Mouth Or Nose).
18. Respiratory Arrest
• This may be result of following:
• Drowning
• Stroke
• Foreign body in throat
• Smoke inhalation
• Drug overdose
• Suffocation
• Accident, injury
• Coma
• Epiglottis paralysis
19. • To restore effective circulation and
ventilation.
• To prevent irreversible cerebral damage
due to anoxia. When the heart fails to
maintain the cerebral circulation for
approximately four minutes the brain
may suffer irreversible damage.
21. (A) Basic techniques for airway patency:
1) Head tilt, chin lift: one hand is placed on the
forehead and the other on the chin the head is tilted
upwards to cause anterior displacement of the
tongue.
23. • 3) Finger sweep: Sweep out foreign body in the
mouth by index finger (in unconscious pt only. This
is NOT advised in a conscious or convulsing patient).
24. • 4) Heimlich manoeuvre: if the pt is conscious or the
foreign body cannot be removed by a finger sweep. It
is done while the pt is standing up or lying down.
This is a sub diaphragmatic abdominal thrust that
elevates the diaphragm expelling a blast of air from
the lungs that displaces the foreign body. In infants
his can be done by a series of blows on he back and
chest thrusts.
35. Sequences of procedures performed to restore the
circulation of oxygenated blood after a sudden
pulmonary and/or cardiac arrest.

45. CHECK BREATHING
• Look, listen and feel for
NORMAL breathing
• Do not confuse agonal
breathing with
NORMAL breathing
46. • Occurs shortly after the heart stops
in up to 40% of cardiac arrests
• Described as barely, heavy, noisy or
gasping breathing
• Recognise as a sign of cardiac arrest
48. 30 CHEST COMPRESSIONS
Approach safely
Check response

Open airway
Check breathing
Call 108
30 chest compressions
2 rescue breaths
49. • Place the heel of one hand in the
centre of the chest
• Place other hand on top
• Interlock fingers
• Compress the chest
– Rate 100 min-1
– Depth 4-5 cm (1.5 to 2 inch)
– Equal compression :
relaxation
• When possible change CPR
operator every 2 min
CHEST COMPRESSIONS
51. • Pinch the nose
• Take a normal breath
• Place lips over mouth
• Blow until the chest
rises
• Take about 1 second
• Allow chest to fall
• Repeat
52. RECOMMENDATIONS:
- Tidal volume
500 – 600 ml
- Respiratory rate
give each breaths over about 1s with enough
volume to make the victim’s chest rise
- Chest-compression-only
continuously at a rate of 100 min
55. DRUGS USED IN CPR
1. ADRENALINE:
Epinephrine is a direct-acting sympathomimetic drug that acts as an
agonist at alpha and beta-adrenergic receptors. It produces
vasoconstriction to counteract the vasodilation and resulting
hypotension associated with anaphylaxis.
Epinephrine hydrochloride produces beneficial effects in patients
during cardiac arrest, primarily because of its α-adrenergic
receptor–stimulating properties. The adrenergic effects
of epinephrine increase myocardial and cerebral blood flow during
CPR.
Given immediately in non shockable rhythm (non VT-VF)
In VF and VT given after the 3 rd shock
REPEATED IN ALTERNATE CYCLE (EVERY 4 MINUTES)
DOSE: 1 mg IV for every 4 minutes
56. DRUGS USED IN CPR
2. AMIODARONE:
It also shows beta blocker-like and calcium channel blocker-
like actions on the SA and AV nodes, increases the refractory period
via sodium- and potassium-channel effects, and slows intra-cardiac
conduction of the cardiac action potential, via sodium-
channel effects.
DOSE: 300 mg IV bolus (5mg/kg)
Given in shockable rhythm after the 3rd shock
If unavailable give lidocaine 100mg IV (1-1.5 mg/kg)
(Blocking sodium channels in the conduction system, as well as the
muscle cells of the heart, raises the depolarization threshold, making
the heart less likely to initiate or conduct early action potentials that
may cause an arrhythmia.)
57. DRUGS USED IN CPR
3. NACHO3:
sodium bicarbonate dissociates to provide sodium (Na+) and
bicarbonate (HCO3
−) anions. Bicarbonate anions can consume
hydrogen ions (H+) and thereby be converted to carbonic
acid (H2CO3), which can subsequently be converted to water (H2O)
and carbon dioxide (CO2) which can be excreted by the lungs.
DOSE: 1 mEq/kg stat and 0.5 mEq/kg every 10 min
Avoid routine use due to complications:
1. Increases co2 load
2. Inhibits release of O2 to tissues
3. Impairs myocardial contractility
58. DRUGS USED IN CPR
4. IV FLUIDS:
Infuse fluids rapidly if hypovolemia suspected
Use normal or ringer lactate solution
5. THROMBOLYTICS
6. VASOPRESSIN
a pituitary hormone which acts to promote the retention of water by
the kidneys and increase blood pressure.
61. Adrenaline
• Adrenaline (epinephrine) is the main drug used
during resuscitation from cardiac arrest.
Atropine
• Atropine as a single dose of 3mg is sufficient to block
vagal tone completely and should be used once in
cases of Asystole. It is also indicated for symptomatic
bradycardia in a dose of 0.5mg - 1mg.
Amiodarone
• It is an antiarrhythmic drug.
62. • Maintains airway patency with use of airway
adjuncts as required (suction, high flow oxygen
with O2 or bag valve mask ventilation).
• Assist with intubation and securing of ETT
• Inserts gastric tube and/or facilitates gastric
decompression post intubation as required.
• Assists with ongoing management of airway
patency and adequate ventilation
63. • Supports less experienced staff by
coaching/guidance e.g. drug preparation
• If a shockable rhythm is present (VF/VT)
ensure manual defibrillator pads are
applied and connected.
• If CPR is in progress, prepare and
independently double check and label 3
doses of adrenaline
• Prepare and administer IV fluids
• Document medications administered
(including time)
