16 Cardiopulmonary Resuscitation and Advanced Cardiac Life Support Flashcards
For non-shockable rhythms, the essential step will be early detection and ______.
Correction of potentially reversible underlying causes
Cardiac output during CPR with effective, uninterrupted
chest compression is at best ______ of the normal spontaneous circulation.
25% to 30%
In cardiac arrests without hypoxic causes (e.g., suffocation, drowning), oxygen content in the lungs at the time of cardiac arrest is usually sufficient for maintaining acceptable arterial oxygen content during the first several minutes of CPR.

______ rather than arterial oxygen content is the limiting factor for oxygen delivery to coronary, cerebral, and systemic circulation during CPR. Thus, rescue breaths are less important than initiating effective chest compressions as soon as possible after SCA.
Blood flow

Como reconhecer Parada Cardiaca? (3)
- Responsividade
- Respiracao ou gasping
- Pulso
(Breathing and pulse check can be performed simultaneously in less than 10 s)
Como ativar o sistema de resposta a emergências? (2)
- Sozinho e sem telefone: deixar a vitima e ativar o sistema de resposta e trazer DEA antes de iniciar RCP
- Caso contrario: enviar alguém e iniciar RCP imediatamente; usar DEA assim que disponivel
Como devem ser as compressões e ventilações em adultos? (4)
- 30:2
- Compressoes 100-120/min
- 1vent q6seg
- 5cm compressao
Compression depth should be no more than 2.4 inches (6 cm).
Compression- only CPR is easy for an untrained rescuer to perform and can be more effectively guided by dispatchers over the telephone. (…) However, for the trained lay rescuer who is able, the recommendation remains for the rescuer to perform both compressions and breaths, especially for victims with asphyxiation causes of cardiac arrest or prolonged CPR.
- V ou F
Verdadeiro
Physiologically, in most cases of SCA, the need for assisted ventilation is a lower priority because of:
- Availability of adequate arterial oxygen content at the
time of an SCA.
The presence of this oxygen and its renewal through gasping and chest compressions (provided there is a patent airway) also supported the use of compression-only CPR and the use of passive oxygen delivery.
Shock First or Chest Compressions in adult witnessed cardiac arrest?
- When an AED is immediately available, the defibrillator should be used as soon as possible.
- Caso contrario, iniciar RCP e colocar DEA assim que disponivel
Por que desfibriladores bifásicos necessitam de menos Joules para choque?
Habilidade de compensar e ajustar a impedancia do paciente
Stacked defibrillation is considered only during: (2)
- Cardiac surgery
- Cardiac catheterization lab. where invasive monitoring and defibrillation pads are in place already.
Em que situacoes a ventilacao é prioridade em relacao a compressões cardíacas? (3)
- Asfixia
- Afogamento
- Sufocamento
Qual o manejo de VA de escolha em PCR (2)
- BVM
- VA Avancada
The choice of bag–mask device versus advanced airway insertion is determined by the skill and experience of the provider.
Qual a FiO₂ que deve ser ofertada em PCR?
100%
What is the most reliable method of confirming and
monitoring correct placement of an ETT?
Capnografia
Em que situacoes a Capnografia pode dar falsos positivos ou negativos?
- Positivo: intubacao esofágica (ventilacoes iniciais)
- Negativos: TEP, ↓DC, doenca pulmonar obstrutiva grave
Por que é necessario cuidado para evitar excesso de ventilações na PCR?
↓Retorno venoso
Principais ddx de Assistolia (2)
- Bradicardia agonal
- FV fina
Qual o efeito de maior beneficio da Epinefrina na PCR
- Alfa: aumenta pressao de perfusão coronariana durante PCR
The β-adrenergic effects of epinephrine are controversial because they may increase myocardial work and reduce subendocardial perfusion.
High- dose epinephrine is not recommended for routine use in cardiac arrest. The exceptions to this recommendation are (3)
- overdose BBQ
- Overdose BCCa
- Epi titulada a parametros fisiologicos monitorizados em tempo real
Qual o momento ideal para Epinefrina na PCR? (2)
- Asystolia / PEA: precoce
- FV ou TVSP: apos Desf
Qual o efeito prognostico de antiarritimicos na PCR por ritmos chocaveis? (2)
- ↑RCE
- ↑Admissao hospitalar
Some antiarrhythmic drugs have been associated with increased rates of ROSC and hospital admission, but none have yet been proven to increase long- term survival or survival with good neurologic outcome.
