Bag-Mask ventilation. • Definition: delivery of positive pressure ventilation to patients with absent or impaired respiratory effort. • Indications: • - Reduced ventilation: cardiac arrest, respiratory failure, accidental oversedation, failed intubation attempt. - Bridge to intubation: following induction of apnoea by administration of sedatives and muscle relaxants. Initiate ventilation: - • Adults: 500-600 mL (6-7mL/kg) tidal volume to 10-12 tidal vo Procedure: Laryngeal mask insertion • • Definition and descriptions: - Supraglottic device used as a temporary method to maintain opening of the airway. - It does not require laryngeal visualisation for adequate placement. - It has tubing, with a 15 mm connector, attached to an elliptical, inflatable cuff at a 30-degree angle. Indications: - Impending or actual loss of airway patency. - Airway protection. - • • Recuse the airway in a failed intubation algorithm. Precautions: - Patient intolerance. - Airway trauma. - May precipitate vomiting and aspiration. Procedure: - Place patient in sniffing position (neutral if suspicion of C-spine injury). - With the distal opening of the LMA facing anteriorly, insert the tip of the LMA into the patient’s mouth. - Advance the mask tip over the hard and soft palate. - Continue to advance the mask as far as possible into the laryngopharynx until resistance is met. - Ensure the black line of the tubing is in line with the patient’s upper lip. - Inflate the cuff with a volume of air as appropriate. - To ensure the effectiveness of placement: misting of the tube, auscultation and etCO2 detection and waveform. - Consider the placement of a bite block and secure the LMA.
