Filter by:This study will compare the ability of pulsed-dose oxygen from a concentrator to reverse altitude-induced hypoxemia compared to compressed gas from a standard oxygen cylinder.
Alfentanil (Alf) is used in combination with Propofol (Pro) in fiber-bronchoscopy and in many other conscious sedation procedures. Alf and Pro have the characteristic of rapid anesthetic onset and quick recovery, synergic sedative effect and unwanted side effects too. However, the amount of Alf needed in combination with Pro for induction and the timing of administration was no standardized. The investigators designed this study to evaluate the optimal regimen, dose and timing of Alf in Target-Controlled infusion (TCI) of Pro for flexible bronchoscopy sedation, and also to evaluate the influence of variable regimen of Alf and Pro on hypoxemia, hypotension, cough severity, and Pro injection related pain.
The risk of respiratory failure after cardiac surgery is high, and it may result in many complications. The maneuver of alveolar recruitment may improve the oxygen transport in the human organism. The investigators compare three different types of alveolar recruitment in patient after cardiac surgery, to reveal which one is better.
The purpose of this study is to determine whether indacaterol maleate 300 micrograms (mcg) is effective in the acute treatment of COPD and in particular on reducing lung hyperinflation and dynamic volumes.
Infants will be observed in the neonatal intensive care unit for 4 hours. The observer will note the timing of oxygen saturation alarms, staff response, and interrupted staff activities.
In the study the value of capnography for avoiding complications during sedation for colonoscopy is evaluated.
In the study the value of capnography for avoiding complications during sedation for ERCP is evaluated.
Morbidity frequency associated to a endotracheal suctioning is different between a necessity endotracheal suctioning protocol versus a routine endotracheal protocol.
The purpose of this study is to evaluate the safety and efficacy of a recruitment maneuver immediately after intubation in hypoxemic patients.
Some patients with chronic obstructive pulmonary disease (COPD) need supplementary oxygen during air travel. Guidelines issued by The British Thoracic Society (BTS) for pre-flight evaluation do not discriminate sufficiently between those who need supplementary oxygen during flight, and those who can do without. Previous studies have indicated that decreasing hemoglobin oxygen saturation during exercise may predict in-flight hypoxemia. The objective of the present study is to examine if adding exercise oxygen desaturation to the BTS algorithm will better predict requirements for in-flight supplementary oxygen.
