 gan's, " nervous or cerebral respiration." Frequent 

 shallow and blowing breathing in low fevers — e. g., in

Resuscitation. (See lllus. Diet.) R., Marshall 

 Hall's Method. See under Artificial Respiration 

 (lllus. Diet.). R. of the New-born, Ogata's 

 Shaking Method, the feet are grasped by one hand 

 and the shoulders held by the other ; the trunk is 

 gradually raised, and the head brought near the feet, 

 the body being strongly flexed at the hip joint while 

 the chest is pressed with the hand. The head is then 

 raised, the trunk gradually extended, and the child 

 thus returned to its former extended position. Should 

 a repetition of this procedure prove unavailing, after a 

 moment's pause in the second position the hand on the 

 back is suddenly removed, the upper part of the child's 



body being thus thrown down and shaken. This 

 should be done eight to ten times a minute, and a 

 warm bath given after each eight or ten shakings. R., 

 Stroke, for asphyxia (Ogata's method): A light stroke 

 over the anteroinferior margin of the chest with the 

 palmar side of the extended fingers, repeated 10 to 15 

 times a minute. The respiration is stimulated, the 

 heart's action excited, and the circulation accelerated.
