The use of the LMA-ProSeal in airway resuscitation

Abstract:
Insufflation of the stomach with air can be a complication of face mask ventilation in the case of airway obstruction. Although the laryngeal mask airway has proven value in airway resuscitation, it has two major failings: a relatively low seal pressure and lack of access to the alimentary tract. A case is reported in which failed intubation (by multiple techniques) and intermittent face mask ventilation resulted in gastric distension, decreased airway compliance, and compromised gas exchange. The patient experience oxyhemoglobin saturation that did not improve despite laryngeal mask ventilation. The patient was resuscitated with a LMA-ProSeal, which permitted ventilation with high airway pressures. Return of oxyhemoglobin saturation occurred after decompression of the stomach with a gastric tube inserted via the LMA-ProSeal's gastric drain.

Ventilatory Modes
There are three ventilatory modes: full support, partial support, and spontaneous. These are described below.
Full Support Modes
Full support modes include controlled mechanical ventilation, continuous mandatory...

Assessment of Respiration
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like asthma or COPD,...
Respiratory Assessment: Purpose and Indications
Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...
