Thirty compressions and two breaths should be continued till either first aid arrives or the person's pulse returns. After 30 compressions take a deep breath, seal your mouth over the person's mouth, pinch their nose, and give two firm breaths. Using the heel of the hand, give 30 compressions.Įach compression should depress the chest by about one third.

For protocol after an infant or child has collapsed with possible cardiac arrest, see figure Pediatric comprehensive emergency cardiac care. Continue giving sets of 30 chest compressions and 2 breaths until: You notice an obvious sign of life An AED is ready to use Another trained responder is. Position the heel of your hands in the centre of the person's chest, interlace your fingers and lift them off the chest. Standards and guidelines for CPR from the American Heart association are followed (see table Child and Infant CPR Techniques for Health Care Practitioners ). You should visualise the 'centre of the chest' and compress at that point. The compressions ventilation ratio is 30:2 (30 compressions to 2 breaths) for infants, children and adults.įind the lower half of the sternum. Objective: Chest compressions are interrupted during cardiopulmonary resuscitation (CPR) due to human error, for ventilation, for rhythm analysis and for. Ventilation for children should occur at.

interruptions to compressions should be minimised Compression to ventilation ratio for children should optimally be 15:2, if possible (such as if there are 2 rescuers).

However, effective infant CPR comes down to proper. Spontaneous gasping by the patient during CPR was able to extend the effectiveness of chest compression only CPR for much longer.When there are no signs of life present, then the rescuer should commence cardiopulmonary resuscitation (CPR). Compressions should be delivered at a rate of 100-120 compressions/minute. The ratio for infant CPR is 30:2, so for every 30 chest compressions, you stop and give 2 rescue breaths. After 3-4 min however, hypoxia meant that continuous compressions became worse than the other techniques. The best oxygen delivery was provided by continuous chest compression in the early stages of CPR. In many practical conditions the compression to ventilation ratio, based on the traditional ABC (airway, breathing circulation) method, is 15 : 2 8. For unwit- nessed cardiac arrest, immediate assessment of the cardiac rhythm by an auto. The ratios of 15:2 and 50:5 produced significantly greater oxygen delivery to the body than 5:1, the greater blood flow with these techniques offsetting the slightly lower arterial oxygen levels. A universal compression:ventilation ratio of 30:2 is recommended. The most appropriate measure of CPR efficiency appears to be the amount of oxygen delivered to the body during CPR. However, the ratio of 5:1 produced the highest arterial oxygen levels, with continuous chest compressions the lowest. After ROSC, oxygenation and ventilation should be titrated to achieve normal values. In infants and children, the method and depth of compressions vary by age. Computer simulations of blood flow and gas exchange during CPR showed that continuous chest compressions produced much greater blood flow (1.39 l/min) than 5:1 (0.73 l/min), 15:2 (0.86 l/min) or 50:5 (0.94 l/min) ratios. A compression to ventilation ratio of 30:2 should be used until an advanced airway is inserted, when a ventilation rate of 10 min 1 should be used without interrupting chest compressions. Two or more rescuers: If a single rescuer is acting, CPR (C-A-B) should be initiated with a ratio of 30 compressions to two breaths if two or more rescuers are acting, the ratio should be 15 compressions to two breaths. However, it is not clear from clinical or experimental studies whether such techniques offer any physiological benefit over more usual 5:1 or 15:2 compression:ventilation ratios.

Simple CPR techniques, such as using only chest compressions, lead to better skill retention and greater willingness to attempt resuscitation on strangers.

Experience has shown that better quality CPR leads to a greater chance of a patient surviving a cardiac arrest. New data reaffirm the key components of high-quality CPR: providing adequate chest compression rate and depth, minimizing interruptions in CPR, allowing full chest recoil between compressions, and avoiding excessive ventilation.
