An ambu (artificial manual breathing unit) device is connected to a patient. Ambu and lungs of the patient are formed a closed system. The pressure value of the closed system PI = 755mmHg, the initial volume of lungs is VL=5L. The initial volume of ambu is VA=1L. Ambu is manually controlled and when it is squeezed to 50% of its initial volume the lungs volume is increased by AV. AV= 582 mL. What will be pressure value (in terms of mmHg) of the closed system after the ambu is squeezed? (PS=?)
