Excessive ventilation during CPR can lead to complications such as increased intrathoracic pressure, which may hinder effective chest compressions and reduce blood flow to vital organs. It can also cause hyperventilation, leading to respiratory alkalosis and a decrease in carbon dioxide levels, which may impair the body's ability to circulate oxygen effectively. This can ultimately reduce the chances of successful resuscitation and recovery. Therefore, it's crucial to deliver ventilations at a controlled rate and volume.
Excessive ventilation during CPR can lead to several adverse effects, including increased intrathoracic pressure, which can impede blood flow to the heart and reduce cardiac output. It may also cause hyperventilation, leading to decreased carbon dioxide levels (hypocapnia) and potentially resulting in respiratory alkalosis. This can impair the body's ability to effectively oxygenate tissues and may hinder the overall success of resuscitation efforts. Proper ventilation techniques should aim for a balance to optimize outcomes.
There are 30 chest compressions between ventilation's for 1-rescuer CPR.
For every 30 compressions, you give 2 rescue breaths.
30:2
30:2
15:2
During CPR the lungs and heart are stimulated.
the same as for 1 person CPR 30:2 (Compression:Breaths)
For 1-person CPR the compression-ventilation ratio for children (and adults and infants) are 30 compressions to 2 breaths.
In an unconscious victim you perform CPR the same for an obstructed airway as you would for regular CPR with one exception, before attempting ventilation you should look for the object in the mouth and if you see it, remove it. But never perform a blind finger sweep!
During CPR the heart and lungs are stimulated.
