The technique used to seal the mask to the patient's face when using a mask in conjunction with a BVM is called the mask seal technique.
Step-by-step explanation:
The technique used to seal the mask to the patient's face when using a mask in conjunction with a BVM (Bag-Valve-Mask) to ventilate a patient is called the <strong>mask seal technique</strong>.
This technique ensures that the mask properly fits the patient's face and creates an airtight seal, which is crucial for effective ventilation.
The mask seal technique involves proper positioning of the mask on the patient's face, ensuring that it covers the nose and mouth completely. The mask is then secured using straps or other fastening mechanisms to hold it in place and maintain the seal.
