A short explanatory foreword to this monograph appears imperative. Abdominal decompression is the device offered for study and consideration to the reader of the following pagesA short explanatory foreword to this monograph appears imperative. Abdominal decompression is the device offered for study and consideration to the reader of the following pages. If that reader accepts, for various cogent reasons, that abdominal decompression has certain effects upon the human organism— these being beneficial—and wishes to try its application, this is simple. Nothing is needed beyond the knowledge that the atmospheric pressure around the human trunk is to be reduced by one to three pounds a square inch of surface. The reader can then improvise some simple equipment and observe the effects of decompression upon him- or herself, upon another laboratory subject or on a patient who is pregnant, in labour, or suffering from menstrual pain or ordinary acute backache. The present work is but a record of the observable phenomena and their variations : matters which can be ascertained independently by the reader. As there is a wide range of application of the method and much time is needed to put possibilities to the test, an experimenter will be saved two years of work if he or she sets out equipped with the knowledge at present available.enLower Body Negative PressureAbdominal CavityPlacentaMicro-Electrical-Mechanical SystemsFetal HemoglobinMalformations of Cortical DevelopmentThesis
