The document provides guidelines for cardiopulmonary resuscitation (CPR) published by the European Resuscitation Council in 2010. It highlights several main changes from the 2005 guidelines, including increased emphasis on high-quality, uninterrupted chest compressions; minimizing interruptions during defibrillation; and recognition of the potential harm of hyperoxaemia after return of spontaneous circulation. Other changes covered include updated treatment recommendations for acute coronary syndromes, greater use of capnography and therapeutic hypothermia, and revised pediatric CPR guidelines focusing on compression quality and automated external defibrillator use in children.
The document summarizes updates to resuscitation guidelines from 2010, including:
- Increasing chest compression depth to 5-6 cm during CPR.
- Emphasizing minimizing disruptions to chest compressions for actions like defibrillation, intubation, and pulse checks.
- Favoring supraglottic airway devices over endotracheal intubation during CPR due to risks of prolonged interruptions to compressions from intubation.
- Simplifying drug administration by giving adrenaline and amiodarone together after the third shock.
2. Special consideration in cardiac rehabilitation program for older adults.ShagufaAmber
An increasing number of cardiac patients are above the age of 65 years . They are susceptible to the adverse effect of bed rest . So early mobilization is especially important to return them to active and independent lifestyle.
- Most of the patients with heart failure, are elderly patients, shooting up to 80% in both incidence and prevalence.This is due to improved and better survival after cardiac insults, such as myocardial infarction, especially in developed countries.(AHA,2013).
-The safety and efficacy of cardiac rehabilitation have been demonstrated in the elderly (age >65 years) .(Pasquali ,et al.,2001)
-CR has a class IA recommendation by the AHA and ACSM for secondary prevention after any coronary heart disease
4. Physiotherapeutic approach of management in mechanically ventilated patient.ShagufaAmber
Mechanical ventilation (MV) is one of the most common interventions in the intensive care unit (ICU). Physical therapy includes early mobilisation to improve functional outcomes. Physical therapy interventions include passive movements of the extremities for deeply sedated patients, in-bed and out-of-bed mobility, active or passive cycling ,neuromuscular electrical stimulation and ambulation.Chest physiotherapy facilitates removal of retained or profuse airway secretions aiming to reduce airway resistance, optimize lung compliance, and decrease the work of breathing. Multimodality respiratory physiotherapy appeared to reduce mortality in ICU patients.

This document summarizes the key changes to cardiopulmonary resuscitation (CPR) guidelines from the American Heart Association in 2010. It emphasizes continued focus on high-quality CPR with adequate rate and depth of chest compressions and minimizing interruptions. It also recommends simplifying training for lay rescuers by starting with chest compressions rather than breaths. Additionally, the guidelines place new emphasis on improving outcomes after cardiac arrest through enhanced post-cardiac arrest care.

Heart failure with preserved ejection fraction (HFpEF) is the fastest growing form of heart failure in the United States and is associated with high morbidity and mortality. It refers to the preserved left ventricular (LV) ejection fraction and this phenotype is more common in older individuals, women, and those with history of hypertension, obesity, and anemia. (Benjamin et al., 2019, Fukuta et al., 2019)Exercise intolerance ( decreased peak oxygen uptake and · Vo2peak) secondary to impaired cardiac, vascular, and skeletal muscle function is a hallmark feature in clinically stable HFpEF patients and is associated with reduced quality of life
The document discusses the negative effects of prolonged bed rest in critically ill patients, including decreased mobility, respiratory function, cardiac output, and muscle mass. It then outlines guidelines and criteria for a mobility protocol in the ICU to safely increase patient mobility and activity levels. The protocol involves 4 levels of increasing mobility from passive range of motion to ambulation. Strict criteria must be met for each level and vital signs are closely monitored during activities. Studies show early mobility protocols can improve patient outcomes like independent functioning and may decrease ICU and hospital length of stay.

This article reviews chest physical therapy techniques used in the intensive care unit (ICU) to clear pulmonary secretions and improve lung function in critically ill patients. Chest physical therapy typically includes postural drainage, percussion, vibration, cough stimulation, breathing exercises, suctioning, and patient mobilization. While studies on the efficacy of chest physical therapy in ICU patients are limited, the resolution of atelectasis and improvements in oxygenation seen in some studies suggest it may help patients in the ICU by removing retained secretions and improving lung function. The article describes indications for treatment and provides details on appropriate chest physical therapy techniques for critically ill patients in the ICU.
1. A Cochrane review found that for untrained bystanders, continuous chest compressions without rescue breathing improved survival to hospital discharge compared to interrupted CPR. For trained professionals, interrupted CPR had slightly better outcomes.
2. The AHA recommends that untrained lay rescuers provide continuous chest compressions with or without dispatcher assistance for adults in cardiac arrest. For trained lay rescuers, compression-only CPR is recommended.
3. A study found no difference in outcomes between continuous compressions with asynchronous ventilations and 30:2 CPR. 30:2 CPR was associated with better outcomes than 15:2 CPR. It may be reasonable for EMS to use 10 breaths per

1. The study examined survival outcomes for pediatric patients receiving extracorporeal cardiopulmonary resuscitation (ECPR) for in-hospital cardiac arrest.
2. Of 199 pediatric patients who received ECPR, 87 (43.7%) survived to hospital discharge.
3. Patients with preexisting cardiac conditions had higher survival rates at 48% compared to other conditions like pneumonia or renal insufficiency which were associated with higher mortality.
1) This study examined the quality of ventilation delivered during simulated cardiac arrest by 97 healthcare professionals from various specialties using a manikin.
2) The participants hyperventilated the simulated patient, providing a mean minute ventilation of 13.1 L/min compared to guidelines recommending 5 L/min.
3) Suboptimal ventilation exceeding guidelines was found across all specialties, though doctors performed best. The results suggest continued hyperventilation during cardiac arrest contrary to guidelines and research on its adverse effects.
The AutoPulse device provides automated chest compressions that are more consistent, effective at circulating blood, and safer than manual compressions. It applies the right amount of pressure tailored to each patient's size using its load-distributing band, improving vital signs and coronary perfusion compared to manual CPR. Clinical studies show it increases rates of return of spontaneous circulation and survival to hospital discharge. The device aims compressions intelligently and stops if an unsafe situation is detected, making it sure, smart, and safe.
This document provides an overview and summary of new standards for procedural sedation set by the Joint Commission on Accreditation of Healthcare Organizations (JCAHO). It discusses the continuum of sedation depth, from minimal to deep sedation. The new JCAHO standards were developed based on American Society of Anesthesiologists guidelines and require facilities to have processes, facilities, equipment, and credentialed personnel for procedural sedation comparable to an operating room. Facilities must meet standards related to patient assessment, care of patients, and improving organizational performance around procedural sedation.

The document summarizes key points from guidelines on pre-hospital resuscitation:
1) Chest compression-only CPR without mouth-to-mouth breaths may increase bystander participation and is supported by a study.
2) Higher energy levels for defibrillation are better when multiple shocks are needed to restore rhythm.
3) New evidence supports paramedics terminating resuscitation efforts for certain out-of-hospital cardiac arrests with very low survival rates.
The document summarizes key changes and recommendations from the 2015 American Heart Association (AHA) Resuscitation Guidelines. Some of the major updates include: emphasizing high-quality chest compressions; allowing higher maximum compression rates of 100-120/min; delaying ventilation for initial continuous compressions; and cautioning on prognostication after resuscitation given new therapies. The guidelines are based on an extensive evidence review process involving hundreds of international participants. While manual CPR remains standard, mechanical devices may be considered in specific settings. Areas for further research are identified around physiologic monitoring during CPR and post-resuscitation care.
1. Adult cardiac arrest requires rapid recognition, prompt CPR, defibrillation of shockable rhythms, and post-resuscitation care and treatment of underlying causes.
2. Key aspects of CPR include compressions at least 2 inches deep and 100-120 times per minute, as well as rescue breaths in a 30:2 ratio prior to advanced airway placement.
3. Early defibrillation is critical for shockable rhythms like ventricular fibrillation, while epinephrine and high-quality CPR improve survival for non-shockable rhythms. Specialized management is also needed for certain patient populations.
This document provides guidelines for resuscitation of adult cardiac arrest victims. It summarizes changes from 2010 guidelines, emphasizing the importance of coordination between emergency dispatchers, bystander CPR, and automated external defibrillators (AEDs) to improve survival. Key changes include endorsing chest compressions-only CPR; maintaining a compression depth of 5-6 cm and rate of 100-120 per minute; and encouraging public access AED programs in locations where cardiac arrests are frequently witnessed. The guidelines apply basic life support techniques like CPR and use of AEDs to increase chances of survival when sudden cardiac arrest occurs.
This document summarizes guidelines for adult advanced cardiovascular life support. It outlines the key components of basic life support including immediate recognition of cardiac arrest, activation of emergency response, early CPR, and use of an automated external defibrillator. For advanced life support, it describes the treatment of shockable (ventricular fibrillation, pulseless ventricular tachycardia) and non-shockable (asystole, pulseless electrical activity) cardiac arrest rhythms. It also reviews adjuncts to CPR including oxygen supplementation, capnography, ultrasound, and airway management techniques.
The document summarizes updates from the 2015 CPR and ECC guidelines developed by the International Liaison Committee on Resuscitation (ILCOR). Key changes included emphasizing high-quality chest compressions, use of automated external defibrillators, and early defibrillation for cardiac arrest. The guidelines were informed by reviews of over 250 studies and recommendations were made using the GRADE methodology. Updates were provided for defibrillation, airway management, drug administration including epinephrine timing, and post-cardiac arrest care such as targeted temperature management.
Basic life support is a course run by American Heart Association that teaches about handling cardiac arrest in Out of Hospital and In Hospital Situations. This Presentation covers important aspects of the same.
This document summarizes guidelines for cardiopulmonary resuscitation (CPR) from 2010. It discusses the history and development of CPR techniques from the 1960s onward. Key points covered include recommendations for chest compressions-only CPR by lay rescuers, a compression-to-ventilation ratio of 30:2, minimizing interruptions in chest compressions, and initial defibrillation energies of 150-200 joules for biphasic defibrillators. The guidelines provide evidence-based recommendations to optimize survival from cardiac arrest.
1. The document discusses advanced cardiac life support (ACLS) guidelines for treating cardiac arrest. It outlines the chain of survival and emphasizes high-quality CPR, defibrillation, airway management, monitoring during CPR, and drug therapy.
2. Key ACLS interventions include chest compressions, rescue breathing, defibrillation, and vasopressor administration to treat cardiac rhythms like ventricular fibrillation.
3. The document also reviews special considerations for cardiac arrest associated with pregnancy and post-cardiac arrest care.
1. Cardiorespiratory arrest is the sudden, unexpected cessation of respiration and functional circulation. CPCR may be successful if performed within 4-6 minutes before biological death of vital tissues develops.
2. CPCR involves circulating oxygenated blood to vital organs like the heart and brain. It aims to restore breathing, circulation, and cerebral functions in those experiencing sudden failure of these systems.
3. Defibrillation is required for ventricular fibrillation, while continued CPR is important for asystole and PEA. Drugs like adrenaline, amiodarone, and atropine may be used if initial shocks and CPR fail to restore a perfusing rhythm.
Cardiopulmonary resuscitation (CPR) involves chest compressions and artificial ventilation to maintain blood flow and oxygen during cardiac arrest. CPR should be started immediately for anyone found unconscious and pulseless. The key steps of CPR include 30 chest compressions followed by 2 rescue breaths in a repeated cycle until a pulse returns or advanced care arrives. Defibrillation using an automated external defibrillator is critical for shockable rhythms like ventricular fibrillation to restore an effective heartbeat. Proper CPR technique is essential to optimize the chances of survival from cardiac arrest.
This document provides an overview of an Advanced Life Support training manual published by the Ministry of Health Malaysia. It was developed by the ALS Subcommittee of the National Committee On Resuscitation Training. The manual covers topics such as airway management, defibrillation, ECG rhythms, drugs used in resuscitation, ALS algorithms, and ethical issues. It is intended to train doctors and healthcare providers in resuscitation skills through lectures, skill stations, and simulated cardiopulmonary cases.
The document discusses the chain of survival and approach to cardiovascular resuscitation for a patient experiencing cardiac arrest. The chain of survival involves 4 steps: 1) activating emergency services, 2) beginning CPR, 3) early defibrillation if needed, and 4) providing advanced care. For a patient in cardiac arrest, rescuers should confirm unresponsiveness, call for emergency help, begin CPR, and use an automated external defibrillator or defibrillator when available to analyze the patient's rhythm and administer shocks if ventricular fibrillation or pulseless ventricular tachycardia is detected. The likelihood of survival increases when each step in the chain of survival is quickly followed.
This document summarizes a seminar on the management of cardiac arrest and cardiac arrest survivors. It defines cardiac arrest and discusses mechanisms and causes. It reviews changes to CPR guidelines including a compression to ventilation ratio of 30:2. It discusses factors that affect blood flow during CPR and prognostic factors for poor outcomes. Management strategies are outlined for defibrillation, antiarrhythmic drugs, vasopressors, steroids and extracorporeal CPR. Adjuncts to CPR like oxygen support and monitoring techniques are also summarized.
The document discusses automated external defibrillators (AEDs), which are portable devices that diagnose and treat ventricular fibrillation by delivering an electric shock to restore a normal heartbeat. AEDs are designed to be simple for laypeople to use with audio and visual instructions. They were first demonstrated on dogs in 1899 and used on humans in 1947. Now, AEDs are recommended for use on people experiencing cardiac arrest who are pulseless and not breathing. To operate an AED, one turns it on, applies adhesive pads to the patient's chest, follows instructions to analyze the heart rhythm and deliver a shock if needed, then resumes CPR. AEDs allow for safer defibrillation and better compliance with
The document outlines the general and specific objectives of a class on cardio pulmonary resuscitation (CPR) and care of the deceased. The general objectives include defining CPR, describing how to perform CPR, outlining risk factors and guidelines. The specific objectives cover introducing CPR, defining it, reviewing causes of cardiac arrest, procedures, drugs used and post-care, as well as introducing death, defining it, physiological changes after death and procedures for caring for the deceased.
The document provides guidelines for basic and advanced life support from the European Resuscitation Council. It outlines the steps for assessing an unresponsive victim and providing CPR, including calling for help, checking breathing and pulse, opening the airway, delivering rescue breaths and chest compressions, using an AED if available, and treating reversible causes of cardiac arrest. It also describes treating shockable and non-shockable heart rhythms, minimizing interruptions to chest compressions, considering advanced airways and vascular access, and focusing on high-quality CPR when performing advanced life support.
A 21-year-old female developed stridor and bilateral pneumothorax after undergoing subtotal thyroidectomy. She required reintubation and mechanical ventilation. Further investigations revealed bilateral pneumothorax, hypocalcemia, and chest infection. She was treated with antibiotics, calcium supplementation, chest tube insertion, and showed gradual improvement over an 11-day hospital stay.
This document provides an overview of shock, including its classification, pathophysiology, diagnosis, and management approaches. Shock is defined as profound reduction in effective tissue perfusion leading to cellular injury. The main types of shock are hypovolemic, cardiogenic, obstructive, and distributive (e.g. septic). Diagnosis involves clinical assessment, lab tests, and potentially invasive monitoring like a pulmonary artery catheter. Treatment focuses on hemodynamic support and reversal of the underlying cause through fluid resuscitation, inotropes, or addressing structural problems.
This document summarizes different types of shock, including their definitions, classifications, pathophysiology, diagnostic approaches, and management strategies. The main types discussed are hypovolemic, cardiogenic, extracardiac obstructive, and distributive shock. Diagnosis involves clinical evaluation, laboratory tests, imaging, and hemodynamic monitoring using a pulmonary artery catheter. Treatment goals are hemodynamic support and reversal of the underlying cause of shock.
Xanthogranulomatous pyelonephritis is a rare chronic kidney infection characterized by a granulomatous reaction. It typically occurs in middle-aged females with a history of recurrent urinary tract infections and is often associated with kidney stones or obstruction. On pathology, lipid-laden macrophages are seen destroying renal tissue in either a diffuse or focal pattern. Clinically, patients experience fever, flank pain, and weight loss. Diagnosis is made through CT scan or ultrasound showing a heterogeneous kidney mass with destruction of renal parenchyma. Treatment involves nephrectomy or partial nephrectomy along with long-term antibiotics. Prognosis is generally good with rare deaths.

Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

4. Keeping the airway open, look, listen and feel for breathing:
• look for chest movement;
• listen at the victim’s mouth for breath sounds;
• feel for air on your cheek;
• decide if breathing is normal, not normal or absent.
In the first few minutes after cardiac arrest, a victim may be
barely breathing, or taking infrequent, slow and noisy gasps. Do
not confuse this with normal breathing. Look, listen and feel for
no more than 10 s to determine whether the victim is breathing
normally. If you have any doubt whether breathing is normal, act
as if it is not normal.
5a. If he is breathing normally:
• turn him into the recovery position (see below);
• send or go for help – call 112 or local emergency number for an
ambulance;
• continue to assess that breathing remains normal.
5b. If the breathing is not normal or absent:
• send someone for help and to find and bring an AED if available;
or if you are on your own, use your mobile phone to alert the
ambulance service – leave the victim only when there is no other
option;
• start chest compression as follows:
◦ kneel by the side of the victim;
◦ place the heel of one hand in the centre of the victim’s chest;
(which is the lower half of the victim’s breastbone (sternum));
◦ place the heel of your other hand on top of the first hand;
◦ interlock the fingers of your hands and ensure that pressure is
not applied over the victim’s ribs. Keep your arms straight. Do
not apply any pressure over the upper abdomen or the bottom
end of the sternum.
◦ position yourself vertically above the victim’s chest and press
down on the sternum at least 5 cm (but not exceeding 6 cm);
◦ after each compression, release all the pressure on the chest
without losing contact between your hands and the ster-
num; repeat at a rate of at least 100 min−1 (but not exceeding
120 min−1 );
◦ compression and release should take equal amounts of time.
6a. Combine chest compression with rescue breaths.
• After 30 compressions open the airway again using head tilt and
chin lift.
