PHYSIOLOGICAL EFFECTS OF IPPB

1) increased mean airway pressure 2) increase tidal volume 3) decreased work of breathing 4) alteration of inspiratory and expiratory time 5) mechanical bronchodilation 6) cerebral blood flow alteration

DECREASED COMPLIANCE results in

an a decreased delivered Vt, when giving a IPPB treatment

INCREASED COMPLIANCE results in

an increased delivered Vt, when giving a IPPB treatment.

DECREASED AIRWAY RESISTANCE results in

an increased delivered Vt, when giving a IPPB treatment

INCREASED AIRWAY RESISTANCE results in

an decreased deliverd Vt, when giving a IPPB treatment

INDICATIONS FOR IPPB THERAPY

-INCREASED WOB -HYPOVENTILATION -ATELECTASIS -PULMONARY EDEMA -DELIVER MEDS TO PT'S WHO CANNOT BREATH IN DEEP -INADEQUATE COUGH -INCREASED AIRWAY RESISTANCE -NEED FOR AID WHEN WEENING FROM MECHANICAL VENTILATOR

HAZARDS OF IPPB THERAPY

-EXCESSIVE VENTILATION (leads to decreased levels of PaCO2) -EXCESSIVE OXYGENATION (in COPD pt's who's normal PaO2 is 50-65mmHg) -DECREASED CARDIAC OUTPUT -INCREASED ICP -PNEUMOTHORAX -HEMOPTYSIS -GASTRIC DISTENTION -NOSOCOMIAL INFECTION

ABSOLUTE CONTRAINDICATION OF IPPB THERAPY

1) UNTREATED PNUEMOTHORAX (IPPB is safe for the pt. with a pnuemothorax who have a chest tube in place) 2) PULMONARY HEMORRHAGE
