This study was designed to test whether awareness of the measurement of breathing influences the breathing pattern in healthy subjects under routine laboratory conditions. Seventy four subjects (40 females and 34 males), aged 21-63 yrs, were studied under three different conditions whilst their breathing was being recorded for 5 min by means of inductance plethysmography (Respitrace): 1) subjec...

BACKGROUND Heat and moisture exchangers (HMEs) are commonly used for humidifying respiratory gases administered to mechanically ventilated patients. While they are also applied to tracheostomized patients with spontaneous breathing, their performance in this role has not yet been clarified. We carried out a bench study to investigate the effects of spontaneous breathing parameters and oxygen fl...

STUDY OBJECTIVE To study tonic inputs to medullary respiratory neurons during rapid eye movement (REM) sleep. DESIGN Single medullary-respiratory-neuron recordings during sleep with spontaneous breathing and during apnea caused by mechanical hyperventilation. SETTING Academic laboratory. SUBJECTS Three tracheostomized adult cats implanted for polysomnography and extracellular microelectro...

The paper describes the design of a novel corpus of respiratory activity in spontaneous multiparty face-to-face conversations in Swedish. The corpus is collected with the primary goal of investigating the role of breathing for interactive control of interaction. Physiological correlates of breathing are captured by means of respiratory belts, which measure changes in cross sectional area of the...

l P r V ρ π Δ = • Abstract—The study deals with the modelling of the gas flow during heliox therapy. A special model has been developed to study the effect of the helium upon the gas flow in the airways during the spontaneous breathing. Lower density of helium compared with air decreases the Reynolds number and it allows improving the flow during the spontaneous breathing. In the cases, where t...

Introduction Weaning from mechanical ventilation is defined as the process of release of ventilatory support and how the evaluation of this phase is conducted in the Spontaneous Breathing Test (SBT). One of the most used modes of SBT is the Continuous Positive Airway Pressure (CPAP). However, together with the mechanical ventilation modes it can be used the Automatic Tube Compensation (ATC), wh...

Background: Electroconvulsive Therapy (ECT) is a successful treatment option for various psychiatric disorders. It is performed under general anesthesia where succinylcholine is the preferred muscle relaxant in this process. However its several contraindications and potential adverse effects, and the fact that it is not always available should be considered. Therefore, finding an effective and ...
