Blood oxygenation during hyperpressure intraperitoneal fluid administration in a rabbit model of severe liver injury: Evaluation of a novel concept for control of pre-hospital liver bleeding

Oxygen is an essential part of the most important metabolic pathways in aerobic organisms. Oxygen delivery is merely dependent on blood, rendering blood loss a devastating event. Traumatic pre-hospital liver bleeding is a major cause of early trauma deaths in human and animals, with no established therapeutic method yet. Increasing intra-abdominal pressure (IAP) has been shown to reduce liver b...

A comparison of the effects of thiopentone and halothane anaesthesia on critical oxygen tension.

RECENT WORK has shown that barbiturate anaesthesia protects tissues against hypoxic damage. ~,2 The mechanism by which this occurs is unknown. ~ However, it is known that barbiturates as well as halothane affect the respiratory enzymes. 4-9 This information has been obtained from tissue culture. Unfortunately it is difficult to extrapolate results from tissue culture to whole animals. It is als...

Hypoxic ventilatory drive in normal man.

A technique is described which permits the inscription of the ventilatory response to isocapnic hypoxia in man as a continuous curve relating alveolar oxygen tension and minute ventilation. The adjustment of ventilation to changes in alveolar oxygen tension is complete in 18-23 sec and this is sufficiently rapid to justify the use of a non-steady-state method. Changes in alveolar carbon dioxide...

Polaro-cryptic mirror of the lookdown as a biological model for open ocean camouflage.

With no object to hide behind in 3D space, the open ocean represents a challenging environment for camouflage. Conventional strategies for reflective crypsis (e.g., standard mirror) are effective against axially symmetric radiance fields associated with high solar altitudes, yet ineffective against asymmetric polarized radiance fields associated with low solar inclinations. Here we identify a b...
