Intermittent Abdominal Pressure Ventilation: An Alternative for Respiratory Support

Table 2

IAPV parameters: we suggest starting with Pbelt of 0–70 Hpa (at the beginning: 30–40 Hpa); select desired Ti (during Ti set, PBAir will be deflated, while the patient will be able to inhale); backup rate as desired; rise time usually 1.0 s; expiratory time (abdominal compression) will be linked to the backup rate and inspiratory time set. For example, set inspiratory time: 1.5 sec, Fr: 15 bpm, and derivative expiratory time: 2.5 sec.
