What happens when you give excess air while ventilating?1 Venous return to the heart is compromised Blood pressure goes up Next breath will be difficult Heart's own blood supply is stopped Roles in a 2-rescuer BLS in a cardiac arrest1 Both gives breaths. One secures the mask, the other squueezes the bag. One rescuer goes to get an AED, the other gives breaths continuously One rescuer gives compressions and other waits for AED One rescuer can give breaths the other, compressions If there are 3 members in a team doing CPR, what can they do ideally1 All can cycle through compressions. All can cycle through ventilations 2 operate the AED and 1 at ventilations 2 alternate for compressions and 1 at ventilations When performing CPR with an advanced airway,1 Compressions are continuous and breaths at every 6 seconds Maintain 30:2 compressions to breaths ratio No need of giving breaths, just continue compressions Advanced airway should be attempted only if there's a pulse Regarding depth of chest compressions1 Compress 1/3rd the chest Compress upto 4cm in adults Compress as deep as possible Compress 5cm depth How to check the response in an adult?1 Gently tap on feet Call his name in a calm composed manner Punch the victim till he responds Use a flash light Firmly tap the shoulders and shout Head tilt – Chin lift1 Head is tilted to one side, left or right Should be attempted only when there is no pulse. Must be avoided if neck injury is suspected Is an advanced airway manouvre, must be done by advanced heath care providers only Regarding a bag mask device1 Use C-E technique to secure the mask on face Ideally used when there are 2 people. All the options are correct Should be used from the head end What is closed loop communication1 Speaking to each other in a closed room, sharing a secret Repeating the given orders back completely Giving an order twice in a loop Acknowledge the order by saying "Got it" When do you check pulse during CPR?1 At the end of 30 compressions, before giving a breath At the end of each breath During compressions At the end of 5 cycles of CPR About rescue breaths1 Given every 5-6 seconds in someone with a pulse Given 30:2 in someone with a pulse Given every 5-6 seconds in someone without a pulse Given every 2 seconds in someone with a pulse What is step 1 while using AED?1 Plug in the connector Remove batteries Turn on the AED Apply pads on victim Call EMS In a 2-rescuer BLS1 Switch roles after 2 minutes Never switch roles Switch roles after 5 minutes Switch roles after 2 cycles What happens with interruptions in chest compressions?1 Drastic improvement in perfusion Perfusion pressures go down Improved output from heart Rescuers get tired What is knowing your limitations?1 Knowing what you are capable of doing and what you are not good at. Knowing the limits of your work location Knowing when to stop the CPR Knowing the complete details about the case In which of these cases, AED pads can be used normally?1 If the victim is in water If there is a medicine patch Unresponsive adult without pulse If there is excess hair on chest If there's an implanted ICD under skin Your AED says shock adviced, what is your next step?1 Press the SHOCK button STOP CPR Listen to AED voice Announce CLEAR Check pulse Which of the following can help you suspect Airway obstruction?1 All of the options Stridor Gurgling sounds Snoring What happens when you compress at a faster rate than recommended 100-120 / min?1 Heart chambers will not have time to refill You will get tired faster Oxygen cannot reach lungs You might break the ribcage What can AED shock do?1 Stop the abnormal rhythm Get the pulse back Prevents the cardiac arrest Shocks the patient to calm him Start the regular rhythm You are part of a team documenting the resuscitation. You notice the ventilations are ineffective. What should you do?1 Tell the person giving breaths to take care of it Complain to the team lead at the end of CPR Pull him out and you start giving effective breaths Just document the error, do not intervene Why is chest recoil important1 Chest recoil helps with oxygenation Increased chest pressures impair blood flow returning to the heart Ribcage gets strengthened with recoil Heart can get injured if there's no recoil Which is not a feature of high quality CPR1 A rate of 100-120 compressions/min Minimize chest recoil Minimize interruptions Depth of 1/3rd chest diameter (2inches/5cms) Position of your hands during Chest compressions1 At 90 degrees to the floor, with elbows bent to 90 degrees At 90 degrees to the floor, with straight elbows Place them close to the neck Place them at the center of abdomen What to do after delivering a shock?1 Resume CPR for 2 minutes Turn off the AED. and do CPR Wait for 2 minutes Remove pads from chest Check pulse for 10seconds For chest compressions to be effective, the surface should be1 Soft and fluffly to avoid injuries Surface with a bump in middle It doesn't matter Flat and firm What is the full form of AED1 Automated external defibrillator Automated energy device Automatic energy delivery Automatic electric defibrillator Adult external defibrillator Back to: BLS Exam
