Q. The compression to ventilation ratio in CPR in case of single rescuer is:(a) 5:2 |
CPR:-(Cardiopulmonary resuscitation) It is emergency medical care to a person whose heart and lung function is going to stop or has recently stopped.In this procedure give the patient artificial respiration and cardiac massage are the two principle components of CPR.
Recognition: Unresponsive, No breathing or no normal breathing i.e only gasping, No pulse palpated within 10 seconds.
CPR sequence: C-A-B (circulation Airway Breathing)
Compression rate: 100 to 120/ min.
Compression depth: At least 2 inches(5cm) in adults, in children at least 1/3 anterior posterior diameter about 2 inches(5cm)
CPR Quality: -Push hard (at least 2 inches[5cm]) and fast (100-120/ min)and allow complete chest recoil.
– minimize interruptions in compressions.
-Avoid excessive ventilation.
– Rotate compressor every 2 minutes, or sooner if fatigued.
– If no advanced airway, 30:2 compression-ventilation ration
– Quantitative waveform capnography-If PETCO2<10 mm Hg, attempt to improve CPR quality
– Intra-arterial pressure- If relaxation phase (diastolic) pressure <20 mm Hg, attempt to improve CPR qulity .
Drugs during CPR:-Epinephrine IV/IO dose: 1mg every 3-5 minutes.
-Amiodarone IV/IO doses: 300mg bolus. second dose 150mg.
Shock Energy for defibrillation:- Biphasic: manufacturer recommendation( eg initial dose of 120-200J) If unknown , use maximum available.
Second and subsequent doses should be equivalent, and higher doses may be considered.
Monophasic: 360J.
