简要总结
- Bag mask ventilation (BMV) has been used routinely for oxygenation and ventilation during induction of anaesthesia, in emergency departments, during transportation of patients by the paramedical staff and especially in cardiopulmonary resuscitation. During emergency situations, the primary care givers might be with less experience to provide the airway care, when anaesthesiologist is not available readily. That’s why all healthcare providers should master the art of BMV. After general anaesthesia the tone of the oral and pharyngeal muscle tone reduces leading to collapse of the tongue, soft palate and epiglottis. An improperly placed fingers especially middle and ring, over the submandibular soft tissue, can compress the upper airway and may lead to obstruction in anesthetized and unconscious apnoeic patients. To bypass the obstruction adjustable pressure level valve will be closed high, which further can lead to gastric insufflation. Therefore we suggest C - ARM, where little finger is placed at the Angle (A), 4th finger over the Ramus (R) and 3rd finger over Mentum (M) of the mandible. This will eliminate the soft tissue compression and airway obstruction by precisely placing the fingers over the mandible and chin lift provided with 3rd finger. It is also easier to remember C – ARM acronym, for novice practitioners.
