Gas exchange and pulmonary stress variations during SCUBA and breath‐hold diving in open seawater
The Journal of Physiology, EarlyView.Abstract figure legend Healthy, trained divers were studied before, during and after diving in open seawater with different techniques. SCUBA divers (diving to 15 or 40 m with air; cycling at depth) and breath‐hold divers (BHDs; sled‐assisted dives to 15, 25 or 40 m) underwent underwater and surface arterial blood gas (ABG) sampling.

The Journal of Physiology, EarlyView.Abstract figure legend Group III/IV leg muscle afferent feedback has previously been recognized as an important determinant of the cardiovascular response to exercise lasting <5 min. Here we demonstrate that the activity of these neurons is crucial in regulating central and peripheral haemodynamic responses during steady state exercise of longer ...

Exercise hyperpnoea: Unravelling layers of regulation
The Journal of Physiology, EarlyView.Abstract figure legend Intensity‐dependent changes in hypercapnic ventilatory response (HCVR) and feedforward gain (GEX) during exercise hyperpnoea below the respiratory compensation point (RCP). Participants (N = 20; 10 females) completed a 44 min step‐incremental cycling protocol in the moderate (below gas exchange threshold (GET)) and heavy ...

The Journal of Physiology, EarlyView.Abstract figure legend Participants completed cycling exercise with (placebo) and without (25 µg intrathecal fentanyl) intact group III/IV muscle afferent feedback in three settings: normoxia, acute hypoxia and chronic hypoxia after 7–9 days of acclimatisation (∼3800 m). Blocking afferent feedback suppressed exercise hyperpnoea across all environments,

Bailliere's Best Practice and Research in Clinical Anaesthesiology, 2014
Since its inception, the pulmonary artery catheter has enjoyed widespread use in both medical and surgical critically ill patients. It has also endured criticism and skepticism about its benefit in these patient populations. By providing information such as cardiac output, mixed venous oxygen saturation, and intracardiac pressures, the pulmonary artery

Current Opinion in Critical Care, 2023
Purpose of review To review recently published data on pulmonary artery catheter (PAC) use in critically ill patients and consider optimal use of the PAC in personalized clinical practice. Recent findings Although PAC use has decreased considerably since the mid-1990s, PAC-derived ...

Current Opinion in Critical Care, 2002
Controversy concerning the pulmonary artery catheter (PAC) and its use as a bedside clinical tool continues to be a significant bone of contention. In the pursuit of evidence-based medicine, a substantial effort has been made over the last 25 years to demonstrate the benefit or lack thereof of PAC-led therapy, and this endeavor still persists with ...

Pediatric Critical Care Medicine, 2011
After its introduction in 1970, the use of the pulmonary artery catheter became a central part of the management of critically ill patients in adult and pediatric intensive care units. However, because it was introduced as a class II device, efficacy for its safety and clinical benefit did not exist during the early years of use.
