Capnography is a graphic representation of the carbon dioxide concentration in the airways plotted against time. We report an unusual biphasic-shaped capnogram in a single-lung transplant recipient. In keeping with the only 2 prior reports of which we are aware, we ascribe the unusual biphasic pattern to differential emptying of the native and transplanted lungs. This experience reminds respira...

Although it has never been prospectively validated, the base excess (BE) is regarded as the standard end-point of resuscitation in trauma patients. In a rat hemorrhage model, in this edition of Critical Care, Totapally and colleagues demonstrate that the BE is an insensitive and slowly responsive indicator of changes in intravascular volume. This contrasts with changes in the esophageal-arteria...

Although there is growing evidence that breathing is modulated by various motor and cognitive activities, the nature of breathing in musical performance has been little explored. The present study examined the temporal breath pattern in piano performance, aiming to elucidate how breath timing is related to musical organization/events and performance. In the experiments, the respiration of 15 pr...

The patient was having a minor procedure undertaken under general anaesthetic and was self-ventilating via a laryngeal mask. Constant gas flows and volatile agent concentration were used and the patient’s minute ventilation remained constant. However, ETCO2 values, as measured by Hewlett Packard M1026A gas analyser (Hewlett Packard, Berkshire, UK), varied between 22 and 43 mmHg. Initially no ca...

The purpose of the study was to review modern recommendations regarding monitoring patients during procedural sedation and analgesia as well assess its conformity standards in Ukraine.
 Materials methods. Recommendations from European, American, British Australian organizations which cover topic or levels anesthesia that conform corresponding ASA, standard anesthesia, were published betwee...
