There is no published data about mask features that impact skin contact pressure during mask ventilation. To investigate the physical factors of skin contact pressure formation. We measured masks with original and reduced air cushion size and recorded contact pressure. We determined cushion contact and mask areas by planimetric measurements. Contact(More)
BACKGROUND Inhalation of l-menthol inhibits cough and has been shown to reduce respiratory discomfort associated with loaded breathing. We investigated the effect of the inhalation of a 1% l-menthol solution in the premedication of fiberoptic bronchoscopy (FB) on the frequency of cough and the irritability of the tracheobronchial mucosa during FB in a(More)
OBJECTIVE We investigated the necessity of using sterile water in humidifiers for avoiding respiratory tract infections during nasal continuous positive airway pressure (nCPAP) therapy. METHODS Water in a convection-type humidifier (Sirius; Heinen and Löwenstein GmbH; Bad Ems, Germany) was labeled with (99m)Tc-diethylenetriamine penta-acetic acid.(More)
BACKGROUND The link between haemoglobin and physical performance was established a long time ago and is the underlying principle of blood doping. Blood loss on the other hand decreases physical capacity. The aim of this study is to evaluate physical performance loss and underlying mechanisms following voluntary blood donation. METHOD AND PATIENTS Eleven(More)
INTRODUCTION Patients receiving mechanical ventilation and oxygen therapy frequently complain about the dryness of their airways. Humidifiers increase air humidity by generating water vapour and thus preventing the mucosa from desiccation. In this bench study, we compared the efficiency of several humidifiers. METHODS Two identical humidifiers of each(More)
Reported in this paper are postoperative results recorded from 120 patients, 3 years after selective proximal vagotomy for uncomplicated duodenal ulcer. There was no intraoperative lethality and no recurrence in 96.7 per cent of all cases, while Visick grades I on II were recorded from 98.2 per cent. Radiologically and gastroscopically detected pathological(More)
Hypercapnic respiratory failure is usually caused by an overload of the respiratory muscles (respiratory pump). After treatment of the underlying disease, mechanical ventilation will achieve optimal treatment success and higher degrees of respiratory muscle unloading will improve the outcome in terms of lower PaCO (2) levels and improved exercise(More)
Pimax measurement is useful for quantifying the fatigue of the respiratory muscles (the "respiratory pump" of the mechanics of respiration), for controlling the therapeutic effect of artificial respiration performed at home, and assessment of the possibility of relieving a patient from artificial respiration. So far, such measurement had required(More)
RATIONALE Non-invasive ventilation (NIV) has been shown to improve clinical outcomes in acute and chronic hypercapnic respiratory failure. A new timed, automated, auto-adaptive non-invasive ventilatory mode (TA-mode) has been recently introduced. OBJECTIVE To investigate the degree of respiratory muscle unloading with this new mode in comparison to(More)
Cough is a common symptom of pulmonary diseases. For a number of reasons it would be of interest to have information about the frequency of coughs over a given period of time. So far, the cough recorders which are available are either too expensive or unwieldy. Hence, we developed a cough recorder linked to a portable, commercially available actigraph(More)
