To the Editor.—
The report entitled "One Caution in Pneumatic Antishock Garment Use" concerns me greatly. The time course for the events from birth is described sketchily. One is left with the impression that the patient underwent cardiopulmonary resuscitation for a considerable interval (how soon after parturition?) before help was summoned. Proper application of the pneumatic antishock garment after an interval of seven minutes without vital signs would increase intraabdominal and inferior vena caval pressure1 and act as a barrier to cephalad migration of blood2 and, presumably, air. Creation of a negative intrathoracic pressure would also be obviated by mechanical ventilation.One should look more closely at the negative intrathoracic pressures created on the release of chest compression during cardiopulmonary resuscitation before sounding an alarm against therapy with the pneumatic antishock garment. To deny therapy of potential lifesaving magnitude like that of a properly applied pneumatic antishock garment
