Abstract

Conventional E-C technique of mask holding is unreliable during single person bag mask ventilation (BMV) due mainly to leak around the mask and inexperience of the persons. In this manikin study, conventional E-C technique was compared with E-O technique during single person BMV both with experienced (n = 50) and novice (n = 50) volunteers. The E-O technique involved encircling the mask neck with the web between thumb and index finger while the other digits provided chin lift. Two independent observers recorded the chest expansion as 1 (nil), 2 (minimal), 3 (moderate) and 4 (good). For analysis ideal and average chest expansion were clubbed as acceptable. E-C technique in experienced volunteers showed acceptable results in 49 (31 ? 18) occasions, while with novices acceptable is 39 (17 ? 22). With E-O technique, expansion was acceptable in 47 (38 ? 9) experienced volunteers, and acceptable in 46 (32 ? 14) novices. (P = 0.003). In cross over analysis for experienced volunteers, similar chest expansion was obta ned on 30 occasions with both techniques, E-C better than E-O on 8 and E-O better than E-C on 12 occasions. Novices had comparable results on 17 occasions, E-C better than E-O on 8 and E-O better than E-C on 25 occasions (P = 0.016). The conventionally taught E-C technique of single person BMV provides acceptable chest expansion on most occasions with experienced operators than novices. Novices should use E-O technique as the first choice for single person BMV. Both techniques may be used interchangeably when one fails.
