The Relationship between Intra-abdominal and Intra-pleural Pressure by Artificial Pneumoperitoneum

Intra-abdominal complications and sequellae of pneumoperitoneum.

Several reports in the literature concern animal experiments with pneumoperltoneum and none of these describes any significant local pathologic changes attributed to the presence of air in the peritoneal space.’ Trimble, Eaton and Moore,2 in 1939, reported necropsy findings In 20 patients who had received pneumoperitoneum for varying lengths of time prior to death. Less than half showed any mnt...

Intra-Pleural Pressure

Intra-abdominal pressure, intra-abdominal hypertension, and pregnancy: a review

The last several decades have seen many advances in the recognition and prevention of the abdominal compartment syndrome (ACS) and its precursor, intra-abdominal hypertension (IAH). There has also been a relative explosion of knowledge in the critical care, trauma, and surgical populations, and the inception of a society dedicated to its understanding, the World Society of the Abdominal Compart...

Interaction Between Intra-Abdominal Pressure and Positive-End Expiratory Pressure

OBJECTIVE The aim of this study was to quantify the interaction between increased intra-abdominal pressure and Positive-End Expiratory Pressure. METHODS In 30 mechanically ventilated ICU patients with a fixed tidal volume, respiratory system plateau and abdominal pressure were measured at a Positive-End Expiratory Pressure level of zero and 10 cm H2O. The measurements were repeated after plac...

On the relationship between intra-oral pressure and speech sonority

We address the question of the relationship between two time series associated to the speech signal. The first one is the sonority function which was introduced in Galves et al. (2002) as an index of the local regularity of the speech signal. The second time series is the intra-oral pressure during the production of speech. We argue that the joint evolution of both time series can be well descr...
