MEASUREMENT OF LUNG DEAD SPACE VOLUME BY CAPNOVOLUMETRY

open access: yesПаёми Сино, 2020
The article provides information on the lung dead space – a part of the respiratory volume that does not participate in gas exchange. The anatomical and alveolar dead spaces jointly together form the physiological dead space.

Understanding the Relationship between Vaccine Supply Dead Space and Wasted COVID-19 Vaccine Doses [PDF]

open access: yesRevista da Sociedade Brasileira de Medicina Tropical, 2023
Introduction: By July 2023, Brazil had administered approximately 540 million COVID-19 vaccine doses. This study aimed to quantify wasted doses resulting from dead space in vaccine supplies.

PUBLIC SPACE IS NOT DEAD

open access: yesOn the W@terfront, 2007
Some authors have announced the death of the public space. It is not for missing. The comfort and security of the commercial centres is operating as a revulsive to the management of the risk that, daily, we should practice in the public 'real space', the street.

A case of bladder and pelvic dead space inflammation successfully treated with endoscopic ultrasound drainage [PDF]

open access: yesClinical Case Reports, 2023
Key Clinical Message Interventional endoscopic ultrasound (EUS) is effective not only for biopsy, but also for abscess drainage. We report the first use of EUS to drain inflammation of the bladder and pelvic dead space through the ileal conduit.

One‐way valves in breathing tubing reduce dead space during spontaneous breathing in anesthetized piglets [PDF]

open access: yesPediatric Discovery
The circle breathing system was unsafe for spontaneous breathing because of hypercapnia during anesthesia. Few studies have examined the minimizing dead space in breathing tubing.

How Does Respiratory Rate Affect Alveolar Ventilation in Pediatric Patients?

open access: yesJournal of Behçet Uz Children's Hospital, 2022
Objective: Minute ventilation is a combination of alveolar ventilation (V'alv) and dead space ventilation which is also a result of multiplication of respiratory rate (RR) by tidal volume.

Correction for Mechanical Dead Space in the Calculation of Physiological Dead Space [PDF]

open access: yesJournal of Clinical Investigation, 1972
When physiological dead space (Vd(p)) is calculated for a patient who has alveolar dead space, e.g., after pulmonary vascular occlusion, less than the full volume of attached mechanical dead space (Vd(m)) appears in the measured dead space (Vd(n)). Under these conditions the traditional subtraction of Vd(m) from Vd(n) leads to underestimation of Vd(p ...

Changes in dead space components during pressure-controlled inverse ratio ventilation: A secondary analysis of a randomized trial.

open access: yesPLoS ONE, 2021
BackgroundWe previously reported that there were no differences between the lung-protective actions of pressure-controlled inverse ratio ventilation and volume control ventilation based on the changes in serum cytokine levels.

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

open access: yesPLoS 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.
