CPR should be initiated in any patient who has a cardiac arrest. This might improve overall outcome but implies that CPR is started in patients without any virtual chance for long-term survival (LTS). The aim of this study is, by analysing retrospectively 2713 out-of-hospital cardiac arrests (CA), to identify indices which might be of help in the decision making to continue or to discontinue CPR. In an important number of unsuccessful CPR attempts ALS-time did not exceed 20 min. This occurred more frequently in subgroups where limited chances of LTS are expected on clinical grounds. The decision to cease CPR might have been based on other clinical and/or ethical parameters which were not recorded in the registry. This behavior results in a "self-fulfilling prophecy". A subset of patients with limited chances for LTS (0/405) can be identified: patients in electromechanical dissociation (EMD) or asystole on arrival of the mobile intensive care unit (MICU) team, without pupil reaction to light during CPR and with inefficient cardiac massage by the MICU (405/2713). Other patients in EMD or asystole without pupil reaction to light during CPR (1373/2713) but with efficient ECC should be resuscitated for more than 30 min, especially if the patient is gasping during CPR (LTS 27/1373). Patients in EMD or asystole on arrival of the MICU with pupil reaction to light during CPR (236/2713) should have an ALS-time of at least 45 min (LTS 42/236). Cardiac arrests in ventricular fibrillation (VF) (699/2713) should be resuscitated for at least 45 min, especially when gasping during CPR (LTS 119/699).

Time is an essential element for successful CPR. Two time factors are particularly important: the duration of complete CA and the time to advanced life support. According to a registration protocol, these time factors, together with other variables and outcome were recorded in 3083 CA cases, treated by the NICU teams of 7 major Belgian hospitals. The mean duration of complete CA is 10.3 min for CPR failure (79%); 5.3 min for initial CPR success (21%); 3.4 min for long-term CPCR success (7%). The mean time to ALS is 19.7 min for CPR failure; 14.6 min for initial CPR success: 12.7 min for long-term CPCR success. Both duration of CA and time to ALS are independently related to outcome; the mean duration of BLS is less than 10 min and not significantly related to outcome. Response time of BLS and ALS are increasingly important in their 'rapid response' failure zone (time to ALS more than 8 min, time to BLS more than 4 min). The tiered MICU system, with nurse paramedics before physicians, has equal time to ALS and comparable outcome results to the non-tiered MICU system. According to our present experience, the following time goals are proposed for Belgian EMS-MICU systems: duration of CA less or equal to 4 min (introduction time less than or equal to 1 min and response time of BLS less than or equal to 3 min) and time to ALS less than or equal to 9 min. These time goals stand, in Belgium for perfection of public training in CPR and for spreading of a higher number of MICU teams countrywide.

Several time intervals, with important influence on the outcome of CA and CPR, are determined by the local EMS-MICU characteristics: time to introduction in the EMS, response time of BLS, duration of BLS before ALS. These time factors have been studied in 2779 out-of-hospital CA cases, treated by the MICU in teams of 7 major Belgian hospitals. The analysis compares the time intervals in the following pre-CPR conditions: the age of the patient; the previous health status of the patient; the disease underlying the CA; the site where CA occurs; the witnessing of the CA; the type of CA; the MICU center, responding to the CA. The mean introduction time is 4.6 min, the mean response time of BLS is 5.1 min, the mean duration of BLS before ALS is 11 min. Introduction in EMS should be improved in CA due to intoxication, drowning, SIDS and respiratory disease, and overall when CA occurs at home.

Outcome after prehospital cardiac arrest was examined in the EMS system of Bonn, a midsized urban community, and presented according to the Utstein style. The data were collected from January 1st, 1989 to December 31st, 1992 by the Bonn-north ALS unit, which serves 240,000 residents. Fifty-six patients suffered from cardiac arrest of non-cardiac aetiology and were excluded; 464 patients were resuscitated after cardiac arrest of presumed cardiac aetiology (incidence of CPR attempts: 48.33 per year/100,000 population). The collapse was unwitnessed, bystander witnessed or EMS personnel witnessed in 178, 214 or 72 patients, respectively. In these subgroups discharge rates and 1-year survival accounted for 7.3% (4.5%), 22.9% (15.9%) and 16.7% (11.1%), respectively. Thirty-four patients were discharged without neurological deficits (cerebral performance category 1: CPC 1), 22 and nine patients scored CPC 2 or CPC 3, respectively. Nine patients were comatose (CPC 4) when they were discharged and remained in this state until they died. Of the 50 1-year survivors 35 lived without neurological deficit, eight demonstrated mild (CPC 2) and five severe (CPC 3) cerebral disability at 1-year after resuscitation, and, finally, two patients remained comatose for more than 1 year. The Utstein template recommends the selection of patients who were found in VF after bystander witnessed collapse. In our cohort 118 patients met these criteria. Of them 41 (35%) could be discharged from hospital and 28 (24%) lived more than 1 year. The comparison of our data with those from double-response EMS systems of other communities revealed that, in midsized urban and suburban communities the highest discharging rates could be achieved. Our study demonstrated that survival depends crucially on short response intervals and life support which will be performed by well-trained emergency technicians, paramedics and physicians.

In April 1997 the ILCOR Basic Life Support advisory statements were announced in conjunction with changes to the recovery position for use in the UK. This study compared the new and old positions by using a questionnaire to assess how well each position satisfied the ILCOR statements. The study was carried out over six different hospital trusts by eight resuscitation training officers. Each tutor alternately taught the 1992 or 1997 recommended positions. After the practical session each student completed a questionnaire on ease of learning and use of the position, as well as other factors such as spinal stability. They were also asked to score the position when they were placed in recovery by other students. Their competency was assessed using the ALS criteria. Over the duration of the study 687 forms were suitable for analysis. For every question there was a significant trend in favour of the 92 position, with students finding the technique easier to learn and use, simpler for positioning for CPR and with less spinal movement during rolling. Possible sources of bias such as previous training, tutor or staff grade made no statistical difference to the results. When performed competently the 1997 position appears to cause less brachial compression, but other problems with learning or use of the 97 position outweigh this advantage. The 1992 position currently provides the best compromise between ease of use, spinal stability and other factors, and better satisfies the ILCOR advisory statements.

Key changes in Guideline 2010 by Japanese Resuscitation Council were described and the reasons of the change were explained based on 2010 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care with Treatment Recommendations. In BLS, the value of chest compression was further emphasized and it became an initial skill of CPR In ALS, post resuscitation care was systemized by incorporating hypothermia, PCI, and other diagnostic and therapeutic modalities. Indication of hypothermia was further expanded to non-VF categories. Use of AED was expanded to infant. Education, Implementation and Teams were newly included as a chapter to promote the knowledge and skill of resuscitation science into the society.

Standard hospital CPR policies in many countries require CPR to be attempted on all patients having a cardiac arrest unless a Not-for-CPR order is in place. It has recently been shown that this approach is legally inappropriate in New Zealand. It appears that this argument may also potentially apply in other common law countries given the role that 'best interests' has in these jurisdictions in providing treatment to patients lacking decision-making capacity. Not-for-CPR orders provide an important and transparent mechanism for making advanced decisions regarding resuscitation. However, advanced planning is not always possible and it is legally inappropriate to require CPR to be performed when it is not in the patient's best interests. Notwithstanding the difficult practical balance that exists at the time of arrest between initiating CPR without delay or interruption for it to be effective for those whom CPR is in their best interests, and recognising as quickly as possible those patients for who CPR is not appropriate, it is argued that policies should be modified to allow clinicians to consider whether CPR is appropriate at time of arrest. Such a change may require ALS training to include a stronger emphasis on early recognition of patients for whom CPR is not in their best interests.

In 2012 the Reassessment Campaign on Veterinary Resuscitation (RECOVER) published evidence-based treatment recommendations for dogs and cats with cardiopulmonary arrest (CPA), to optimize the clinical practice of small animal CPR and positively impact outcomes. Six years after the release of these guidelines, we aimed to determine the compliance of small animal veterinary CPR practices with these RECOVER guidelines. To identify current CPR practices in clinically active small animal veterinarians and their awareness of the RECOVER guidelines, we conducted an internet-based survey. Survey invitations were disseminated internationally via veterinary professional organizations and their social media outlets. Questions explored respondent demographics, CPR preparedness, BLS and ALS techniques and awareness of RECOVER guidelines. Responding small animal veterinarians (n = 770) in clinical practice were grouped by level of expertise: board-certified specialists (BCS, n = 216) and residents (RES, n = 69) in anesthesia or emergency and critical care, practitioners in emergency (GPE, n = 299) or general practice (GPG, n = 186). Large disparities in preparedness measures, BLS and ALS techniques emerged among levels of expertise. Only 32% (95% CI: 29-36%) of respondents complied with BLS practice guidelines, varying from 49% (95% CI: 42-55%) of BCS to 15% (95% CI: 10-20%) of GPG. While incompliances in BCS, RES, and GPE were predominantly due to knowledge gaps, GPG compliance was further compromised by limitations in the resuscitation environment (e.g., defibrillator availability, team size). Those aware of RECOVER guidelines (100% of BCS and RES; 77% of GPE; 35% of GPG) were more likely to comply with recommended preparedness (OR = 2.4; 95% CI: 1.2-4.8), BLS (OR = 4.5; 95% CI: 2.4-9.1), and ALS techniques (OR = 7.8; 95% CI: 2.4-9.1) independent of age, gender, region of practice or level of expertise. We conclude that awareness of RECOVER guidelines is high in specialists and residents, but incomplete among general practitioners. This awareness positively influenced compliance with CPR guidelines, but CPR practices continue to be variable and largely not in agreement with guidelines. A widely accessible educational strategy is required to broadly improve compliance with best practices in small animal CPR.
