Estimation of Patient’s Inspiratory Effort From the Electrical Activity of the Diaphragm*

Critical Care Medicine, 2013
To calculate an index (termed Pmusc/Eadi index) relating the pressure generated by the respiratory muscles (Pmusc) to the electrical activity of the diaphragm (Eadi), during assisted mechanical ventilation and to assess if the Pmusc/Eadi index is affected by the type and level of ventilator assistance.

"Effects of fenoterol on inspiratory effort sensation and fatigue during inspiratory threshold loading"

Journal of Applied Physiology, 1996
We studied the effects of a single dose of fenoterol on the relationship between inspiratory effort sensation (IES) and inspiratory muscle fatigue induced by inspiratory threshold loading in healthy subjects. The magnitude of the threshold was 60% of maximal static inspiratory mouth pressure (PI,mmax) at functional residual capacity, and the duty ...

Relationship between inspiratory drive and perceived inspiratory effort in normal man

Clinical Science, 1990
1. To examine the relationship between the inspiratory effort sensation (IES) and respiratory drive as reflected by mouth occlusion pressure (P0.1) we have studied loaded and unloaded ventilatory responses to CO2 in 12 normal subjects. 2.

Rib cage deformation during static inspiratory efforts

Journal of Applied Physiology, 1979
Patterns of rib cage (RC) deformation were studied in six normal subjects during moderate static inspiratory efforts such that esophageal pressure (Pes) as an index of transthoracic pressure fell to between -30 and -60 cmH2O during each maneuver. At lung volumes below 50% inspiratory capacity (IC), static inspiratory efforts deformed RC to a more ...

Expiratory versus inspiratory efforts in suffocating pigeons

Agents and Actions, 1972
The respiration of anaesthetized pigeons, suffocated to death by tracheal occlusion, is followed by means of the intratracheal pressure tracing. A special procedure allows to distinguish expiratory from inspiratory efforts.

Relationship between inspiratory effort and breathlessness in pregnancy

Journal of Applied Physiology, 1991
Using open-magnitude scaling, we compared the relationships between breathlessness, inspiratory esophageal pressure swing (delta Pes), and ventilation in pregnancy and postpartum. Thirteen healthy women performed progressive cycle exercise tests at 33 +/- 2 wk gestation and 12 +/- 3 wk postpartum.

Airway Occlusion Pressure as an Estimate of Respiratory Drive and Inspiratory Effort During Assisted Ventilation.

American Journal of Respiratory and Critical Care Medicine, 2020
Rationale Monitoring and controlling respiratory drive and effort may help to minimize lung and diaphragm injury. Airway occlusion pressure (P0.1) is a non-invasive measure of respiratory drive.

The impact of inspiratory effort on inspiratory flow through Turbuhaler in asthmatic patients

European Respiratory Journal, 1997
To investigate the impact of the inhalation effort on the peak inspiratory flow through Turbuhaler, 100 asthmatics having a wide range of asthma severity (baseline forced expiratory volume in one second 28-127% of predicted normal) were studied.

REDUCED INSPIRATORY EFFORT DURING INTERMITTENT MANDATORY VENTILATION WITH PEEP

Survey of Anesthesiology, 1976
The use of intermittent mandatory ventilation (IMV) and positive and expiratory pressure (PEEP) may demand the patient mount an inspiratory pressure equivalent to the pressure level of the PEEP for spontaneous breathing. During respiratory failure, ineffective inspiratory muscles may be unable to consistently meet such demands, especially if high ...

Assessing inspiratory drive and effort in critically ill patients at the bedside

Critical Care
Monitoring inspiratory drive and effort may aid proper selection and setting of respiratory support in patients with acute respiratory failure (ARF), whether they are intubated or not.
