NCT06911541
Comparing a wireless accelerometer-based sensor that continuously measure breathing rate with the gold standard capnography. The aim is to evaluate if both methods are equivalent.
NCT06824610
This study aims to detect the effect of different O2 flow rates on end tidal carbon dioxide level in patients scheduled for minor gynaecological procedures under deep sedation using laryngeal mask airway. * Primary outcome was measuring end tidal carbon dioxide ( EtCO2 ) non invasively by laryngeal mask all through the procedure. * Secondary outcomes included peripheral O2 saturation, hemodynamics, time to recovery, total propofol dose, patients' satisfaction, sedation score, and complications.
NCT05817864
A prospective observational diagnostic study will be conducted to assess the sensitivity and specificity of using capnography in detecting the correct placement of nasogastric tubes using the reference standards of radiography and measurement of aspirates for pH value.
NCT05696860
Purpose: Researchers wanted to investigate the effect of capnography monitoring in addition to routine monitoring on the development of desaturation and other vital parameters in endobronchial ultrasonography (EBUS) cases. Method: 100 patients who underwent EBUS under sedation will be included in this prospective and randomized controlled study. The cases will be divided into two groups of 50 people each. In the first group, standard monitoring will be performed, and in the second group, in addition to standard monitoring, capnography monitoring will be used. Heart rate, blood pressure, peripheral oxygen saturation (SpO2) values in both groups, end-tidal carbon dioxide (EtCO2), respiratory rate and integrated pulmonary index (IPI) values in the second group will be recorded in all cases. Disturbances in vital parameters and airway interventions, which were common in both groups, will ve compared. The frequency of problems detected by capnography monitoring in the second group will be examined.

Type 2 diabetes mellitus (T2DM) poses a significant burden on the patients and the health care system. The increasing number of surgery performed in elderly population results in an increased number of perioperative T2DM-related adverse effects. T2DM has a prevalence of 30-40% in a population undergoing cardiovascular surgery. Cardiac surgery, especially cardiopulmonary bypass (CPB) is also known to deteriorate respiratory mechanics. The vascular effects of T2DM are well characterized, however, its effects on the mechanical properties of the respiratory system or the exhaled carbon-dioxide concentration curve (capnogram) during and following CPB are yet to be fully discovered. Therefore, the study is aimed at characterizing the respiratory consequences of T2DM, i.e.: i: deteriorations of airway function that might be a result of smooth muscle dysfunction; ii: deterioration of the viscoelastic properties of the lung as a result of lung volume loss or structural changes, iii: exploring whether the changes of respiratory mechanics caused by cardiac surgery exhibit a different time course in T2DM and control patients. The study also aims at characterizing the effects of T2DM on capnogram parameters: i: whether it influences capnogram shape factors, ii: whether any differences can be detected in the dead-space parameters and iii: whether cardiac surgery has a different effect on capnogram parameters in T2DM patients compared to controls.
NCT02816190
Beneficial effect of prone position in ARDS on mortality is not linked to increase in PF ratio. It is probably due to improvement in ventilation-perfusion ratio (V/Q). Volumetric capnography allows assessment of dead space and homogeneity of V/Q. All prone positionned patients will be included in the study with usual monitoring (i.e. respiratory system basic mechanics, volumetric capnography, blood gas samples). Epidemiologic and monitoring data will be collected during all prone position sessions.
NCT02889770
This studies´ objective is to describe how different PEEP levels affect dead space measured by Bohr´s formula.
