Working Principle of Manual Ventilators

Manual ventilators operate by delivering airflow through a mechanical process, often involving a compressible bag or valve system. They rely on operator effort to provide breathing support, ensuring reliable ventilation in emergency or clinical settings.

3.1 Mechanism of Airflow Delivery

Manual ventilators deliver airflow through a compressible bag or valve system, enabling controlled breath delivery. The operator squeezes the bag to push air into the patient’s lungs, while the valve regulates airflow direction. This mechanism ensures consistent ventilation, with the operator adjusting compression force to maintain appropriate pressure and flow, critical for patient oxygenation and carbon dioxide removal in emergency or clinical settings.

3.2 Role of the Operator in Manual Ventilation

The operator plays a crucial role in manual ventilation, requiring skill and attention to ensure effective airflow delivery. They must compress the bag or adjust valves to regulate pressure and flow, tailoring breaths to the patient’s needs. Proper technique, including rate and force, is vital to maintain adequate ventilation and prevent complications, emphasizing the importance of training and real-time adaptability in critical situations.
