Inspiratory Effort and Lung Mechanics in Spontaneously Breathing Patients with Acute Respiratory Failure due to COVID-19: A Matched Control Study. [PDF]

Am J Respir Crit Care Med, 2021
A great debate has started as to whether acute respiratory failure (ARF) induced by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection (coronavirus disease [COVID-19]) should be classified as a classic form of acute respiratory ...

Effects of non-invasive respiratory supports on inspiratory effort in moderate-severe COVID-19 patients. A randomized physiological study. [PDF]

Eur J Intern Med, 2022
Rationale and objective Various forms of Non-invasive respiratory support (NRS) have been used during COVID-19, to treat Hypoxemic Acute Respiratory Failure (HARF), but it has been suggested that the occurrence of strenuous inspiratory efforts may cause ...

Inspiratory threshold loading negatively impacts attentional performance

Frontiers in Psychology, 2022
RationaleThere are growing concerns over the occurrence of adverse physiologic events (PEs) occurring in pilots during operation of United States Air Force and Navy high-performance aircraft. We hypothesize that a heightened inspiratory work of breathing

Positive end-expiratory pressure limits inspiratory effort through modulation of the effort-to-drive ratio: an experimental crossover study. [PDF]

Intensive Care Med Exp
How assisted spontaneous breathing should be used during acute respiratory distress syndrome is questioned. Recent evidence suggests that high positive end-expiratory pressure (PEEP) may limit the risk of patient self-inflicted lung injury (P-SILI).

Central venous pressure swing outperforms diaphragm ultrasound as a measure of inspiratory effort during pressure support ventilation in COVID-19 patients. [PDF]

J Clin Monit Comput, 2022
Purpose The COVID-19-related shortage of ICU beds magnified the need of tools to properly titrate the ventilator assistance. We investigated whether bedside-available indices such as the ultrasonographic changes in diaphragm thickening ratio (TR) and the

Early Inspiratory Effort Assessment by Esophageal Manometry Predicts Noninvasive Ventilation Outcome in De Novo Respiratory Failure. A Pilot Study. [PDF]

Am J Respir Crit Care Med, 2020
Rationale: The role of inspiratory effort still has to be determined as a potential predictor of noninvasive mechanical ventilation (NIV) failure in acute hypoxic de novo respiratory failure.

Comparison of inspiratory effort with three variable-flow nasal continuous positive airway pressure devices in preterm infants: a cross-over study. [PDF]

Arch Dis Child Fetal Neonatal Ed, 2021
Objective Patient’s work of breathing may vary between different neonatal nasal continuous positive airway pressure (NCPAP) devices. Therefore, we aimed to compare the inspiratory effort of three variable-flow NCPAP delivery systems used in preterm ...

Differential effects of repeated inspiratory and limb muscle loading on effort perception in patients with obstructive sleep apnea and healthy males

Physiological Reports, 2023
Obstructive sleep apnea (OSA) is characterized by collapse of the upper airways during sleep. The contribution of alterations in effort perception is not understood. This study investigated the response of inspiratory and quadriceps muscles to repetitive

Outcomes of ventilatory asynchrony in patients with inspiratory effort. [PDF]

Rev Bras Ter Intensiva, 2020
Objective To identify the relationship of patient-ventilator asynchrony with the level of sedation and hemogasometric and clinical results. Methods This was a prospective study of 122 patients admitted to the intensive care unit who underwent > 24 hours ...

Effect of inspiratory synchronization during pressure-controlled ventilation on lung distension and inspiratory effort

Annals of Intensive Care, 2017
Background In pressure-controlled (PC) ventilation, tidal volume (V T) and transpulmonary pressure (P L ) result from the addition of ventilator pressure and the patient’s inspiratory effort.
