CARDIO-PULMONARY RESUSCITATION

DEFINITIONS
‡
‡
‡
‡
‡
‡

Respiratory arrest = the absence of breathing movements.
Cardiac arrest = the clinical picture of overall cessation of circulation.
Clinical death = coma, apnea and pulselessness in large arteries with cerebral
failure still potentially reversible.
Biological death = the irreversible absence of body functions due to irreversible
structural cell damage.
Cerebral death = the irreversible absence of brain and brainstem functions with
temporary presence of respiration and circulation.
Persistent vegetative state = absence of motility and reaction to external stimuli
due to persistent absence of cerebral activity with preservation of vegetative
functions (respiration, circulation, swallowing).
CARDIO-PULMONARY ARREST
Physiopathology
respiratory arrest ? / cardiac arrest ?
‡

There are semnificative differences, related to age, in the incidence of
primary respiratory arrest (more frequent in newborns and children) and
primary cardiac arrest (more frequent in adults and old persons)

‡

There are semnificative differences of BLS in primary respiratory arrest
and primary cardiac arrest.

RESPIRATORY ARREST

‡ Pathophysiology

± Heart and lungs continue the tissue delivery of oxygenated blood until exhaution of
alveolar O2 reserves; pulse is present, altered consciousness;
± Delay to cardio-circulatory arrest: variable (seconds-minutes); it depends on:
‡ Oxygen reserve in the moment of respiratory arrest (PAO2 şi PaO2)
‡ Miocardial capacity to sustain hypoxemia
± Uncorrected respiratory arrest results in cardiac arrest;

‡ Causes
± Drowning,, foreign body aspiration, toxic inhalation, epiglotitis, strangulation, etc.
± Coma of any origin, stroke, etc.
± Electrocution, trauma, etc.

‡ Clinical signs

Cardiac arrest results in circulatory arrest with the immediate cessation of tissue O2 delivery;
Cessation of brain O2 delivery:
‡ Depletion of O2 reserves in 10 seconds
‡ Depletion of phosphocreatine reserves in 2 minutes
‡ Depletion of glucose and ATP reserves in 5 minutes
For a short time delay (always seconds): agonal respiration (Gasping) (unefficient respiratory efforts with
recruitment of accessory respiratory muscles);
Always cardiac arrest result in respiratory arrest;

CARDIO-PULMONARY RESUSCITATION
DEFINITION

arrest in order to artificially deliver the oxygenated
blood to systemic circulatory beds at rates that are
sufficient to preserve the vital organ function and at
the same time providing the physiologic substrate for
the return of spontaneous circulation.

‡ The most important determinant of survival from sudden

(2005 AHA Guidelines for CPR and ECC, Circulation, 2005)

‡ ÄIn the 1990s some predicted that cardio-pulmonary
resuscitation (CPR) could be rendered obsolete by the
widespread development of community automated external
defibrillator (AED) programs. Cobb noted, however, as more
Seatle first responders were equipped with AEDs, survival
rates from sudden cardiac arrest fell. He atributted this
decline to reduces emphasis on CPR....´

CPR recomendations 2006 ± 2 esential aspects for the success of CPR:

‡ Avoid hiperventilation
±
±
±
±
±

for a pulmonary gas exchange (pulmonary blood flow decreased)
encrease the intrathoracic pressure
decrease the cardiac upload
decrease the efficience of chest compresions
stomach insuflation (encrease the risk of regurgitation/aspiration, push up the
diaphragm and encrease the intrathoracic pressure)

‡ Avoid interupting the chest compresions

± CPR performed by trainned medical team ± total time of interupting chest
compresions 24-49% of the cardiac arrest duration.
± Any interuption in chest compresions means the decrease of coronary
perfusion pressure, which slowly rises when the chest compresions are
delivered once again, and so the chances of returning to spontaneous
circulation are decreased.
± In the first minutes of cardiac arrest (VF) the artificial ventilation is not so
important as the chest compresions because the hipoxy is primary caused by
the lack of tissulary perfussion, and there are sufficiently blood O2 rezerves
in the first minutes. That is why the rescue person should concentrate in
delivering efficient chest compresions. The new recommendations regarding
the sequence chest compresions/ventilation 30:2 are made to minimalise the
time of chest compresion interuptions.

RESUSCITAREA CARDIO-RESPIRATORIE

F DEFIBRILAREA:
Defibrilarea este un termen utilizat pentru a desemna
livrarea nesincronizată cu complexul QRS a unui şoc
electric.
Şocul electric induce o depolarizare sincronă urmată de
repolarizare sincronă a tuturor fibrelor miocardice.
Deci, după şocul electric toate fibrele miocardice
ajung la un numitor comun: ´zero´ electric. Acest
fenomen permite intrarea în funcţie a centrului cardiac
cu funcţie spontană de pacemaker, care va prelua
controlul activităţii electrice şi mecanice a inimii.

ŞOCUL ELECTRIC EXTERN
‡ Termenul de cardioversie este utilizat pentru

şoc electric. Sincronizarea evită livrarea
şocului în perioada refractară relativă a ciclului

‡ Bolnavul trebuie să aibă monitorizare ECG şi monitorizarea

    CPR recomendations 2006± 2 esential aspects for the success of CPR: ‡ Avoid hiperventilation ± ± ± ± ± for a pulmonary gas exchange (pulmonary blood flow decreased) encrease the intrathoracic pressure decrease the cardiac upload decrease the efficience of chest compresions stomach insuflation (encrease the risk of regurgitation/aspiration, push up the diaphragm and encrease the intrathoracic pressure) ‡ Avoid interupting the chest compresions ± CPR performed by trainned medical team ± total time of interupting chest compresions 24-49% of the cardiac arrest duration. ± Any interuption in chest compresions means the decrease of coronary perfusion pressure, which slowly rises when the chest compresions are delivered once again, and so the chances of returning to spontaneous circulation are decreased. ± In the first minutes of cardiac arrest (VF) the artificial ventilation is not so important as the chest compresions because the hipoxy is primary caused by the lack of tissulary perfussion, and there are sufficiently blood O2 rezerves in the first minutes. That is why the rescue person should concentrate in delivering efficient chest compresions. The new recommendations regarding the sequence chest compresions/ventilation 30:2 are made to minimalise the time of chest compresion interuptions.

    RESUSCITAREA CARDIO-RESPIRATORIE F DEFIBRILAREA: Defibrilareaeste un termen utilizat pentru a desemna livrarea nesincronizată cu complexul QRS a unui şoc electric. Şocul electric induce o depolarizare sincronă urmată de repolarizare sincronă a tuturor fibrelor miocardice. Deci, după şocul electric toate fibrele miocardice ajung la un numitor comun: ´zero´ electric. Acest fenomen permite intrarea în funcţie a centrului cardiac cu funcţie spontană de pacemaker, care va prelua controlul activităţii electrice şi mecanice a inimii.
