- 1. BASIC LIFE SUPPORT (BLS) Mr. Ahmed Sodha M.Sc. (N). – M.S.N.
- 2. Introduction • According to recent statistics sudden cardiac arrest is rapidly becoming the leading cause of death. • Once the heart ceases to function, a healthy human brain may survive without oxygen for up to 4 minutes without suffering any permanent damage. Unfortunately, a typical EMS response may take 6, 8 or even 10 minutes. • It is during those critical minutes that CPR (Cardio Pulmonary Resuscitation) can provide oxygenated blood to the victim's brain and the heart, dramatically increasing his chance of survival and if properly By- Ahmed Sodha
- 3. What is BLS ? • Basic Life Support (BLS) refers to the care healthcare providers and public safety professionals provide to patients who are experiencing respiratory arrest, cardiac arrest or airway obstruction. • BLS includes psychomotor skills for performing high-quality cardiopulmonary resuscitation (CPR), using an automated external defibrillator (AED) and relieving an obstructed airway for patients of all ages. By- Ahmed Sodha
- 4. Timeline of CPR • 0 to 4 minutes, unlikely development of brain damage • 4 to 6 minutes, possibility of brain damage • 6 to 10 minutes, high probability of brain damage • 10 minutes and over, probable brain damage By- Ahmed Sodha
- 5. Indications • Road Traffic Accident • Drowning • Electric Shock • Airway Obstruction • Cardiac Arrest By- Ahmed Sodha
- 6. Goals of Resuscitation • To support and restore effective:- - oxygenation - ventilation - circulation with return of intact neurologic function • ROSC (Return of spontaneous circulation) is an intermediate goal By- Ahmed Sodha
- 7. CHAIN OF SURVIVAL By- Ahmed Sodha
- 8. a.) For Adults By- Ahmed Sodha
- 9. b.) For Pediatric • Emergencies in children and infants are not usually caused by the heart. Children and infants most often have breathing problems that trigger cardiac arrest. The first and most important step of the Pediatric Chain of Survival is prevention By- Ahmed Sodha
- 11. Latest changes in AHA Guidelines (In 2015) • Change in sequence to C-A-B from A-B-C • Emphasis on high quality CPR • No look, listen and feel • No routine use of cricoid pressure during bag mask ventilation • Continued de-emphasis on pulse check By- Ahmed Sodha
- 12. CAUTION Use of cricoid Pressure • The routine use of cricoid pressure in cardiac patients is not recommended. • Cricoid pressure in nonarrest patients may offer some measure of protection to the airway from aspiration and gastric insufflation during bag and mask ventilation. However, it also may impede ventilation and interfere with placement of a supraglottic airway or intubation By- Ahmed Sodha
- 13. In 2020 Guideline • The importance of early initiation of CPR by lay rescuers has been re-emphasized. The risk of harm to the patient is low if the patient is not in cardiac arrest. Bystanders should not be afraid to start CPR even if they are not sure whether the victim is breathing or in Cardiac Arrest. • A sixth link, Recovery, was added to the Chains of Survival for both Pediatric and Adults. • Care of the patient after return of spontaneous circulation (ROSC) requires close attention to oxygenation, blood pressure control, evaluation for percutaneous coronary intervention, targeted temperature management, and multimodal neuroprognostication. By- Ahmed Sodha
- 14. Contd.. • Because recovery from cardiac arrest continues long after the initial hospitalization, patients should have formal assessment and support for their physical, cognitive, and psychosocial needs. • After a resuscitation, debriefing for lay rescuers, EMS providers, and hospital- based healthcare workers may be beneficial to support their mental health and well-being. • Management of cardiac arrest in pregnancy focuses on maternal resuscitation, with preparation for early perimortem cesarean delivery if necessary to save the infant and improve the chances of successful resuscitation of the mother.

- 69. PRIMARY ASSESSMENT By- Ahmed Sodha
- 70. AIRWAY • Is the airway patent ? • Is an advanced airway indicated? • Is proper placement of airway device confirmed? • Is tube secured and placement confirmed frequently? By- Ahmed Sodha
- 71. Is the airway patent ? • Maintain the airway patency in unconscious patients by use of the head tilt-chin lift , oropharyngeal airway or nasopharyngeal airway By- Ahmed Sodha
- 72. Is an advanced airway indicated? • Use advanced airway management if needed (eg- laryngeal mask ,laryngeal tube , oesophageal –tracheal tube, endotracheal tube) NOTE:- Health care providers must weighs the benefit of advanced airway placement against adverse effects of interrupting chest compressions. If bag-mask ventilation is adequate, health care providers may defer insertion of advanced airway. By- Ahmed Sodha
- 73. Contd… If using advanced airway devices:- • Confirm proper integration of CPR and ventilation • Confirm proper placement of advanced airway devices by - Physical examination - Quantitative waveform capnography • Secure the device to prevent dislodgement • Monitor airway placement with continuous quantitative waveform capnography By- Ahmed Sodha
- 74. Continuous waveform capnography • Quantitative waveform capnography is the continuous, noninvasive measurement and graphical display of end-tidal carbon dioxide/ETCO2 (also called PetCO2). Capnography uses a sample chamber/sensor placed for optimum evaluation of expired CO2. • The inhaled and exhaled carbon dioxide is graphically displayed as a waveform on the monitor along with its corresponding numerical measurement. By- Ahmed Sodha
- 75. Contd.. Two very practical uses of waveform capnography in CPR are: 1.) evaluating the effectiveness of chest compressions, and 2.) identification of ROSC. Evaluating the effectiveness of chest compressions is accomplished in the following manner: Measurement of a low ETCO2 value (< 10 mmHg) during CPR in an intubated patient would indicate that the quality of chest compressions needs improvement. • Normal ETCO2 in the adult patient should be 35-45 mmHg. • High quality chest compressions are achieved when the ETCO2 value is at least 10- 20 mmHg. By- Ahmed Sodha
- 76. Contd.. • When ROSC occurs, There will be a significant increase in the ETCO2. (35- 45 mmHg) This increase represents a drastic improvement in blood flow (more CO2 being dumped in the lungs by the circulation) which indicates circulation. By- Ahmed Sodha
- 77. Contd.. • The 2020 AHA Guidelines for ACLS recommend using quantitative waveform capnography in intubated patients during CPR. Waveform capnography allows providers to monitor CPR quality, optimize chest compressions, and detect ROSC (return of spontaneous circulation) during chest compressions. • Also, according to the AHA, continuous waveform capnography along with clinical assessment is the most reliable method of confirming and monitoring correct placement of an ET tube. By- Ahmed Sodha
- 78. BREATHING • Are ventilation and oxygenation adequate? • Are quantitative waveform capnography and oxyhemoglobin saturation monitored? By- Ahmed Sodha
- 79. Contd.. • Give supplementary oxygen when indicated - For cardiac arrest patients, administer 100% oxygen - For others, titrate oxygen administration to achieve oxygen saturation of 94% or greater by pulse oximetry • Monitor the adequacy of ventilation and oxygenation by - Clinical criteria( chest rise and cyanosis) - Quantitative waveform capnography - oxygen saturation • Avoid excessive ventilation By- Ahmed Sodha
- 80. CIRCULATION • Are chest compressions effective? • What is the cardiac rhythm? • Is defibrillation or cardioversion indicated? • Has IV/IO access been established? • Is ROSC present? • Is the patient with a pulse unstable? • Are medications needed for rhythm or blood pressure? • Does the patient need volume (fluid) for resuscitation? By- Ahmed Sodha
- 81. Contd.. • Monitor CPR quality - Quantitative waveform capnography (if PETCO₂ is less than 10 mm Hg, atte to improve CPR quality) - Intra-arterial pressure (if relaxation phase [diastolic] pressure is less than 20 mm Hg, attempt to improve CPR quality) • Attach monitor/defibrillator for arrhythmias or cardiac arrest rhythms (eg, tricular fibrillation [VF], pulseless ventricular tachycardia [PVT], asystole, pulse electrical activity [PEA]) • Provide defibrillation/cardioversion By- Ahmed Sodha
- 82. Contd.. • Obtain IV/IO access • Give appropriate drugs to manage rhythm and blood pressure • Give IV/IO fluids if needed • Check glucose and temperature • Check perfusion issues By- Ahmed Sodha
- 83. DISABLITY • Check for neurologic function • Quickly assess for responsiveness, levels of consciousness, and pupil dilation • Assess for AVPU A - Alert V - Voice P - Painful U- Unresponsive By- Ahmed Sodha
- 84. EXPOSURE • Remove clothing to perform a physical examination, looking for obvious signs of trauma, bleeding, burns, unusual markings, or medical alert bracelets By- Ahmed Sodha
- 85. SECONDARY ASSESSMENT • Secondary assessment involves the differential diagnosis, including a focused medical history and searching for and treating underlying causes (H;s andT;s) • Ask specific question related to the patient's presentation consider using memory aid SAMPLE By- Ahmed Sodha
