The correct compressions-to-ventilations ratio during a 1-person rescue on an adult :True
What is ventilations ratio?
The ventilatory ratio is a straightforward bedside assessment that assesses compromised ventilation by using commonly measurable respiratory variables. The ventilation ratio is calculated as follows: (predicted body weight 100 37.5)/(minute ventilation (ml/min) PaCO2 (mm Hg)]. The number of times a rescuer aggressively depresses a victim's chest during emergency cardiac care for each breath given. For each cycle of cardiopulmonary resuscitation, the American Heart Association (2010) recommends that an adult perform 30 chest compressions, followed by 2 ventilations. When a single rescuer is working alone, the same ratio is applied for newborns and kids. With a baby or young toddler, two rescuers should work in a 15:2 ratio.
