HEART AND STROKE BLS|UPDATED&VERIFIED|100% SOLVED|GUARANTEED SUCCESS

high-quality CPR start compressions within 10 seconds of recognition of cardiac arrest compression rate 100-120/min depth of compression for adults At least 2 inches depth of compression for children one-third the death of the chest about 2 inchs or 5 cm depth of compression for infants one-third the depth of the chest about 1 and 1/2 inch or 4 cm IHCA In hospital cardiac arrest OHCA Out of hospital cardiac arrest chain of survival OHCA call 911, CPR, AED, EMS, ED, Cath lab, ICU cardiac arrest is based on unresponsiveness, no breathing or no normal breathing or only gasping and no pulse cardiac arrest in children usually which order cardiac arrest is often secondary to respiratory failure and shock sudden cardiac arrest definition occurs when the heart develops abnormal rhythm and cannot pump blood a heart attack definition occurs when the blood flow two part of the heart muscle is blocked heart attack symptoms severe discomfort in the chest or areas of the upper body, shortness of breath, cold sweats, nausea / vomiting and women and men can experience pain in the jaw arms and back or neck, lightheadedness, nausea vomiting Hands-On CPR a single rescuer with little training and limited equipment who witnesses a cardiac arrest may do chest compressions only until help arrives CPR consists of three main components chest compressions, airway, breathing no normal breathing but has pulse provide rescue breathing, one breath every 5 to 6 seconds or about 10 to 12 breaths a minute single rescuers perform 30 compressions to 2 breaths ratio Chest recoil Allows blood to flow into the heart if a jaw thrust does not open the airway use a head tilt chin lift one-way valve mask it diverts exhaled air blood or bodily fluids away from The rescuer and allows The rescuers breath to enter the victim's mouth and nose one way valve mask fitting technique placing the mask on the patient's face using the bridge of the nose is a guide for a correct position the air we breathe out and the air we breathe in the air we breathe out 17% oxygen and the air we breathe in is 21% oxygen deliver each breath over what amount of time one second and checking for visible chest rise squeeze BVM over how many seconds over 1 second when should two rescuers switch compressions about every two minutes or five cycles typically when the AED is analyzing the rhythm try to limit interruptions of CPR to less than blank seconds 10 seconds PAD Public access defibrillation always after a shock or the AED prompts no shock advised - given you must do blank resume high-quality CPR it is better to give higher effective CPR then shock with child pads if you place pads directly over implanted medical device the implanted medical device may blank block delivery of shock to the heart chest compression fraction is the proportion of time that chest compressions are performed during cardiac arrest and at least 60% is recommended and a goal of 80% or greater is often achievable with good teamwork
