Over-response of needle is normal. Note: MEDUMAT Basic / Basic p briefly switches to expiration if the maximum ventilation pressure is exceed- ed, but then tries to continue inspiration in the same inspiration phase. If the maximum ventilation pressure is exceeded for a second time during the same inspiration phase, the unit finally switches to expiration and vents the patient tube system completely. -
