Ans;D. Empty stomach.
This technique is bag and mask ventilation
Bag-valve-mask ventilation
- It is an essential emergency skill .
- This basic airway management technique allows for oxygenation and ventilation of patients until a more definitive airway can be established and in cases where endotracheal intubation or other definitive control of the airway is not possible.
- In the pediatric population, BVM may be the best option for prehospital airway support.
- BVM ventilation is also appropriate for elective ventilation in the operating room when intubation is not required, but it is now often substituted by the laryngeal mask airway.
- BVM ventilation requires a good seal and a patent airway.
- Bag-mask ventilation can produce gastric inflation with complications, including regurgitation, aspiration, and pneumonia.
- Gastric inflation can elevate the diaphragm, restrict lung movement, and decrease respiratory system compliance.
- Indications for bag-valve-mask ventilation include
- respiratory failure (failure of ventilation and/or oxygenation) and failed intubation.
Contraindications:
- severe facial trauma
- complete upper airway obstruction
- After paralysis and induction (because of the increased risk of aspiration)
Full stomach patients - Patients at high risk of aspiration like pregnancy and hiatus hernia.
Intestinal obstruction. - Diaphragmatic hernia (as there will be distension of bowel increasing further respiratory difficulty).
- Tracheo-esophageal fistula (air through fistula can lead to increase in gastric pressure).
- Meconium aspiration syndrome (as patient has already aspirated, bag and mask ventilation will further increase aspiration)
