Influence of a Six-Week Swimming Training with Added Respiratory Dead Space on Respiratory Muscle Strength and Pulmonary Function in Recreational Swimmers. [PDF]

Int J Environ Res Public Health, 2020
The avoidance of respiratory muscle fatigue and its repercussions may play an important role in swimmers’ health and physical performance. Thus, the aim of this study was to investigate whether a six-week moderate-intensity swimming intervention ...

A non invasive estimate of dead space ventilation from exercise measurements. [PDF]

PLoS ONE, 2014
RATIONALE: During exercise, heart failure patients (HF) show an out-of-proportion ventilation increase, which in patients with COPD is blunted. When HF and COPD coexist, the ventilatory response to exercise is unpredictable.

Warm-Up With Added Respiratory Dead Space Volume Mask Improves the Performance of the Cycling Sprint Interval Exercise: Cross-Over Study [PDF]

Frontiers in Physiology, 2022
Special breathing exercises performed during warm-up lead to hypercapnia and stimulation of mechanisms leading to increased exercise performance, but the effect of a device that increases the respiratory dead space volume (ARDSv) during warm-up has not ...

Impairment in Preextubation Alveolar Gas Exchange Is Associated With Postextubation Respiratory Support Needs in Infants After Cardiac Surgery

Critical Care Explorations, 2022
OBJECTIVES:. To determine if indices of alveolar gas exchange preextubation predict postextubation respiratory support needs as well as the need for escalation of therapies following infant cardiac surgery. DESIGN:. Retrospective chart review.

Dead space estimates may not be independently associated with 28-day mortality in COVID-19 ARDS

Critical Care, 2021
Background Estimates for dead space ventilation have been shown to be independently associated with an increased risk of mortality in the acute respiratory distress syndrome and small case series of COVID-19-related ARDS.
