Stimulation of sciatic nerve produced a rise in arterial blood pressure followed by a fall with an increase in the rate and depth of respiration in dogs under pentobarbitone anaesthesia. Application of cotton swabs soaked with GABA in 0.9 % saline to the spinal cord at Ll and L. segments did not change the basal arterial pressure and respiratory rate, but elicited only the pressor effect of sci...

Tracheostomy used to be reserved for the severely ill patient with acute respiratory obstruction. As the incidence of diphtheria declined the operation came to be performed only occasionally, particularly as the high mortality and complication rates associated with the use of tracheostomy in diphtheria were well remembered. But within the past 20 years a great change has occurred as the indicat...

N Engl J Med 2007;357:e4. Copyright © 2007 Massachusetts Medical Society. Indications Providing positive-pressure ventilation with a face mask and a bag-valve device can be a lifesaving maneuver. Although seemingly simple, the technique requires an understanding of the airway anatomy, the equipment, and the indications. Face-mask ventilation is used in patients who have respiratory failure but ...

This study aimed to update knowledge regarding to noninvasive ventilation (NVI) on postoperative of cardiac surgery in addition at investigating if exists superiority of any modalities NVI in relation to the others. The literature review was performed on the period between 2006 and 2011, on PubMed, SciELO and Lilacs databases crossing the keywords: artificial respiration, continuous positive ai...

OBJECTIVE To compare the effects of 3 types of noninvasive respiratory support systems in the treatment of acute pulmonary edema: oxygen therapy (O2), continuous positive airway pressure, and bilevel positive pressure ventilation. METHODS We studied prospectively 26 patients with acute pulmonary edema, who were randomized into 1 of 3 types of respiratory support groups. Age was 69+/-7 years. ...

The postural control system dynamically interacts with the respiratory system [2], as spontaneous respiration alters the body’s center-of-mass. In order to study this multi-system interaction, we introduced a new metric termed posturerespiratory synchronization. This metric quantifies the effect of respiration on the body’s postural sway (as measured by center-of-pressure, COP, movement under t...

The interaction between respiration and lowfrequency rhythms of the cardiovascular system is studied. The obtained results count in favor of the hypothesis that low-frequency rhythms in blood pressure and R-R intervals are generated in different central neural structures involved in the autonomic control of the cardiovascular system. Keywords—Cardiovascular system, R-R intervals, blood pressure...

Cheyne-Stokes respiration (CSR) during sleep is common in patients with congestive heart failure (CHF). This pattern of breathing fragments sleep, leading to daytime symptoms of sleepiness and fatigue. It was hypothesized that by controlling CSR with noninvasive pressure preset ventilation (NPPV), there would be a decrease in sleep fragmentation and an improvement in sleep quality. Nine patient...

Respiration rate allows to differentiate between happy and sad excerpts which may be attributable to entrainment of respiration to the rhythm or the tempo rather than to emotions [Etzel, J.A., Johnsen, E.L., Dickerson, J., Tranel, D., Adolphs, R., 2006. Cardiovascular and respiratory responses during musical mood induction. Int. J. Psychophysiol. 61(1), 57-69]. In order to test for this hypothe...
