Objective description of mask ventilation

Difficult mask ventilation.

Mask ventilation is the most fundamental skill in airway management. In this review, we summarize the current knowledge about difficult mask ventilation (DMV) situations. Various definitions for DMV have been used in the literature. The lack of a precise standard definition creates a problem for studies on DMV and causes confusion in data communication and comparisons. DMV develops because of m...

Noninvasive Nasal Mask Ventilation

Setting: A ward of respiratory medicine of a tertiaryreferral teaching hospital. Patients: The study group included 15 patients with acute respiratory acidosis. These patients had pH less than 7.35 and PaC02 more than 60mm Hg, respiratory rate of 30 breaths or less per minute, hemodynamic stability, and alertness and willingness of cooperation with the NMV treatment. The control group consisted...

Difficult mask ventilation.

To the Editor:-As a bearded anesthetist, 1 was interested to read the solution of Drs. Johnson, Bradway, and Blood to the problem of good mask ventilation in the presence of an hirsute face.' Although they are correct in their assertion that it is a frequently encountered situation, they are incorrect in their statement that the only previously published solution has been to skive the patient p...

Noninvasive ventilation is more than mask ventilation.

Prediction of difficult mask ventilation.

BACKGROUND Maintenance of airway patency and oxygenation are the main objectives of face-mask ventilation. Because the incidence of difficult mask ventilation (DMV) and the factors associated with it are not well known, we undertook this prospective study. METHODS Difficult mask ventilation was defined as the inability of an unassisted anesthesiologist to maintain the measured oxygen saturati...
