Nasal Mask

Full-Face Mask

Total Face Mask

mode n Spontaneous(S) n Spontaneous/Timed(S/T) n Timed(T) n CPAP

操作 n IPAP Control：range 4 -30 cm. H 2 O (Inspiratory positive airway pressure) n EPAP Control ：range 4 -30 cm. H 2 O (Expiratory positive airway pressure) n BPM Control ：range 4 -30 BPM (Breaths per minute) n %IPAP Control ：range 10 -90 % is a time control mode %IPAP time functional in Timed(T) Mode only， %IPAP的 設定值如果大於 50%，I/E inverse

IPAP 增加tidal volume；減少Pa. CO 2 減少tidal volume；增加Pa. CO 2 EPAP 增加FRC 減少tidal volume；增加Pa. O 2 減少FRC 增加tidal volume；減少Pa. O 2 如果EPAP<4 cm H 2 O，可能造成CO 2 再吸入

FIO 2 增加Pa. O 2 減少Pa. O 2 Rate 增加minute volume in time mode， 減少Pa. CO 2 減少minute volume in time mode， 增加Pa. CO 2

pressure line連接處

OFL 兩個壓力監視器的壓力相差 1 cm. H 2 O Assess the patient Check for circuit disconnect Check the proximal pressure line Check the ventilator system, circuit configuration and settings.

flashing 兩次呼吸間的漏氣>15 LPM Assess the patient Check the circuit for excessive leak Check mask for large leaks

ooo >20 sec以上沒有流量的變化 Assess the patient for apnea and adequate ventilation Check the ventilator system, circuit configuration and settings. Verify unit is triggering properly

氧氣 n O 2供應：連接O 2 flow meter應小於 15 L/min或等於 15 L/min
