How Manual Resuscitators Work
A manual resuscitator operates by compressing a flexible bag to push air into a patient’s lungs, providing ventilation when they cannot breathe independently․ This simple, portable device ensures reliable emergency respiratory support․
4․1 Mechanism of Operation
A manual resuscitator functions by compressing a self-inflating bag to deliver air into a patient’s lungs, simulating natural breathing․ The device includes a bag valve mask (BVM) system, where the bag is squeezed to push air through a one-way valve into the patient’s airway․ Exhaled air escapes through a separate valve, preventing rebreathing․ Optional features like oxygen reservoirs and PEEP valves enhance ventilation efficiency and control․ The mechanism ensures reliable, portable respiratory support in emergencies․
4․2 Oxygen Supply and Delivery
A manual resuscitator can be connected to an external oxygen source to deliver enriched oxygen to the patient․ The oxygen flows through tubing into the device, often passing through a reservoir to increase oxygen concentration․ The bag is compressed to push oxygenated air into the lungs․ Some models include flow meters or pressure gauges to regulate oxygen delivery․ Optional features like PEEP valves help maintain consistent airway pressure, ensuring efficient ventilation and improving patient outcomes in critical situations․
