Filter by:Oxygenation with high-flow nasal cannula with 100% oxygen has only been evaluated in a limited number of studies. Although data are convincing it is of importance to evaluate this new concept in our department before implementing it into clinical practice. The general purpose of this project is to evaluate a new ventilation strategy during ENT-surgery based on oxygenation with high-flow nasal cannula with 100% oxygen with focus on gas exchange.
Electric Impedance Tomography (EIT) is a technique based on the injection of small currents and voltage measurements using electrodes on the skin surface generating cross-sectional images representing impedance change in a slice of the thorax.It is a radiation free, non- invasive and portable lung imaging technique. Impedance changes in lung ventilation as well as in lung perfusion can be shown. To investigate lung perfusion by EIT measurements, cardiac output measured by routinely undergone stress echocardiography at rest and stress are compared to parameters measured by EIT.
Home bi-level positive pressure ventilators are equipped with built-in softwares which measure and record specific items such as tidal volume, total ventilation, leaks, respiratory rate, cycles triggered by the patient. These items have not to date been described in a large group of patients under home mechanical ventilation.
The purpose of this study is to find out, whether it is possible to improve the ventilatory care of premature infants by using Neurally adjusted ventilatory assist (NAVA). The study hypothesis is that by using NAVA-technology and/or by monitoring Edi-signal (the electrical signal of diaphragm), it is possible to accomplish ventilatory care to premature infants more individually.
The purpose of this study is to find out if NAVA-technology is better in detecting patients own inspiratory efforts during mechanical ventilation than currently used flow-triggering in PRVC (pressure regulated volume controlled) ventilation, and if NAVA gives real benefits for patients or not. The investigators study hypothesis is that NAVA-technology can detect spontaneous inspiration more accurately than currently used methods, and thus will lead to more smooth adaptation to mechanical ventilation in pediatric patients. The investigators expect this to decrease the time of ventilatory support needed.
Investigation of effects of SiPAP versus NCPAP on oxygenation and ventilation in LBW infants with respiratory distress. Our hypothesis is that the LBW infants will achieve the same level of oxygenation and improved ventilation when being treated with SiPAP as compared to NCPAP.
To evaluate the effectiveness of use of the bispectral index for monitoring of depth of sedation in ventilated patients during their prehospital management by a physician- staffed EMS. Hypothesis: there is a correlation between BIS and sedation scores.
In ventilated patients open endotracheal suctioning may lead to alveolar derecruitment, which can be monitored by means of functional residual capacity (FRC) measurements. The investigators hypothesized that a recruitment strategy based on FRC measurements would improve oxygenation and regional ventilation after an open endotracheal suctioning manoeuvre.
The ProSeal laryngeal mask airway (PLMA) is a new laryngeal mask device with a modified cuff to improve the seal and a drain tube to prevent aspiration and gastric insufflation. The manufacturer recommends inserting the PLMA using digital manipulation, like the Classic LMA, or with an introducer tool (IT), like the Intubating LMA. The mean (range) frequency of insertion success at the first attempt for these techniques is 84% (81-100) and 95% (90-100) respectively, with the main causes of insertion difficulty being impaction at the back of the mouth and failure of the distal cuff to reach the hypopharynx. Howarth et al described an insertion technique which overcomes these difficulties by using a gum elastic bougie (GEB) placed in the esophagus to guide the PLMA around the back of the mouth and into its correct position in the hypopharynx. Howarth et al reported no failed uses from 100 consecutive insertions. In the following study, we test the hypothesis that GEB-guided insertion is more frequently successful than the digital and IT techniques in patients with difficult airway.
Background: Fracture of several ribs in more than one place as the result of trauma, leads to paradoxical movement of the chest wall and ventilatory failure. The mainstay of management in these patients has traditionally been analgesia and positive pressure ventilation to splint the chest wall and allow healing of the ribs to begin. However, this management option leads to prolonged intensive care unit (ICU) stay with increasing complication rates as patients remain on a ventilator for prolonged periods. Patients often remain on a ventilator for two to three weeks while waiting for enough rib healing to provide sufficient chest wall stability to allow the patient to take over all their breathing themselves. Until that time, patients are at risk of pneumonia and sepsis and other complications. Long term disabilities which have been reported in these patients include ongoing pain syndromes, inability to return to work, particularly manual type labour and cosmetic chest wall deformities. An alternative treatment strategy is to operatively fix the ribs. By fixing the ribs operatively, the patient no longer requires internal pneumatic stabilization (provided by mechanical ventilation) and can be weaned from the ventilator within days rather than weeks. This can potentially lead to earlier discharge from the intensive care unit, and an avoidance of the multiple complications which arise in the ventilated patient. Rib fixation may also lead to less pain and deformity, improved mobility in the post injury phase and earlier return to work. Hypothesis: that early operative fixation of ribs in patients presenting with flail chest secondary to trauma will result in less mechanical ventilatory requirements, earlier discharge from the intensive care unit and lower rate of complications associated with prolonged mechanical ventilation. This will lead to cost savings in the treatment of these patients.
