Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of standard and a modified method of two resuscitator adult cardiopulmonary resuscitation: description of a new system for research into advanced life support skills.
The study compares two methods of Advanced Life Support by a pair of resuscitators using a bag-valve-mask (BVM) technique. Standard two resuscitator cardiopulmonary resuscitation (CPR) was compared with a modified method of two resuscitator CPR. During the modified CPR one resuscitator held the face mask while the other resuscitator alternates between squeezing the self inflating bag and performing simulated cardiac compressions. ⋯ Modified CPR produced a greater tidal volume (TV) (P < 0.001), a slower respiratory rate (RR) (P < 0.001) and a faster compression rate (CR) (P < 0.01) (means with (S. D.): modified CPR: TV 990 (220) ml, RR 6 (1) min(-1), CR 82 (8) min(-1); standard CPR: TV 570 (190) ml, RR 10 (2) min(-1), CR 65 (11) min(-1)). A new method for the simultaneous computerised recording of simulated cardiac compressions together with mask pressure and expired gas composition in anaesthetised patients is described.
