This study hypothesizes that a novel reversal V-E ventilation technique will retain its high efficiency as that of standard V-E technique and will be easier to use.
Despite advances in intubation technology, difficult airways persist. Because it is failure to oxygenate, not failure to intubate, that ultimately leads to brain injury and cardiovascular collapse, effective mask ventilation is at least as important as successful intubation. Therefore optimizing mask ventilation is crucial for clinicians. When difficult mask ventilation encounters, clinicians often switch to two hand technique to hold the mask including either "C-E" clamp or "V-E" clamp. Both volume mode ventilation and pressure mode ventilation are superior with the V-E technique as compared to the C-E technique. The study will test the hypothesis that a novel reversal V-E mask ventilation technique will retain its high efficiency as that of standard V-E technique but be easier to use than standard V-E technique.

A type of oropharyngeal airway that provides an alternative to endotracheal intubation and standard mask anesthesia in certain patients. It is introduced into the hypopharynx to form a seal around the larynx thus permitting spontaneous or positive pressure ventilation without penetration of the larynx or esophagus. It is used in place of a facemask in routine anesthesia. The advantages over standard mask anesthesia are better airway control, minimal anesthetic gas leakage, a secure airway during patient transport to the recovery area, and minimal postoperative problems.
Techniques for administering artificial respiration without the need for INTRATRACHEAL INTUBATION.
Ventilatory support system using frequencies from 60-900 cycles/min or more. Three types of systems have been distinguished on the basis of rates, volumes, and the system used. They are high frequency positive-pressure ventilation (HFPPV); HIGH-FREQUENCY JET VENTILATION; (HFJV); and high-frequency oscillation (HFO).
Techniques for effecting the transition of the respiratory-failure patient from mechanical ventilation to spontaneous ventilation, while meeting the criteria that tidal volume be above a given threshold (greater than 5 ml/kg), respiratory frequency be below a given count (less than 30 breaths/min), and oxygen partial pressure be above a given threshold (PaO2 greater than 50mm Hg). Weaning studies focus on finding methods to monitor and predict the outcome of mechanical ventilator weaning as well as finding ventilatory support techniques which will facilitate successful weaning. Present methods include intermittent mandatory ventilation, intermittent positive pressure ventilation, and mandatory minute volume ventilation.
Mechanical ventilation delivered to match the patient's efforts in breathing as detected by the interactive ventilation device.
