Duo Positive Airway Pressure: A Case Study

My mode is Duo Positive Airway Pressure on the Hamilton G5. It is pressure control, a set inspiratory pressure is set to be proportional to patient inspiratory pressure. The breath sequence is intermittent mandatory ventilation (IMV). Ventilatory support is between mandatory and spontaneous breaths. The rate setting directly affects the number of mandatory breaths and the level of ventilatory support. Spontaneous breaths are allowed between mandatory breaths. DuoPAP has two set points; the therapist’s sets two pressure levels the inspiratory positive airway pressure (IPAP) and expiratory positive airway pressure (EPAP). DuoPAP is equivalent to pressure support ventilation with CPAP. The tidal volume depends on the patient effort and the difference between IPAP and EPAP (IPAP-EPAP). IPAP determines how much volume the patient will receive. EPAP determines how much PEEP will be delivered during exhalation. DuoPAP on the Hamilton G5 is pressure targeted, patient triggered, and flow cycled.

For patients with acute exacerbation of COPD to not be intubated. For patients with congestive heart failure, pulmonary edema, and obstructive sleep apnea. Restrictive thoracic disorders and neuromuscular diseases. Cystic fibrosis patients who have acute exacerbation. Hypoxemic respiratory failure and acute respiratory distress syndrome. Patients who develop mild to moderate hypercapnia or hypoxemia after extubation. Moderate to severe dyspnea, accessory muscle use, paradoxical breathing, and a respiratory rate greater than twenty-four breaths per min. Also, on an arterial blood gas a pH less than 7.35 and PaCO2 greater than 45
