Individual air cells deflate to protect patient's vulnerable areas in prone position

Treating ARDS with Prone Position Ventilation 

Prone position ventilation is proven to provide substantial clinical benefits to patients with moderate or severe acute respiratory distress syndrome (ARDS) (PaO2/FiO2200 mmHg). Patients treated in a prone position during mechanical ventilation are usually in a prone position for prolonged periods >12 hours per day1. According to various published clinical studies, prone position ventilation could improve oxygenation through more uniform distribution of blood flow/airflow for ARDS patients2. 

Excessive pressure to vulnerable areas increases pressure injury risks and recovery time 

Prone positioning significantly increases pressure injury risk in vulnerable areas. Non-optimized pressure distribution system applies excessive pressure to vulnerable areas such as the patient's face, ears, shoulder, chest, genitalia, iliac crests and anterior leg region, resulting in a higher risk of pressure injury complications and longer recovery3. The original clinical practice was that to further reduce the pressure exerted on breasts, abdomen, or knees, a caregiver team lifts the patient's chest, pelvis, or chin to insert pillows. Lacking proper tools for caregivers to keep track of pressure settings for different regions of the support surface increases the burden on the caregiver's workload.

Protect patient's vulnerable areas   

Optima Prone mattress provides the individual air cell deflation feature.  

It allows the caregivers to customize the pressure-relief area based on patient’s body contour, height, and clinical condition, to optimize pressure injury prevention effect. 

Control over individual air cell airflow allows zero pressure and personalized care to vulnerable areas, preventing pressure-induced injuries and avoiding excess pressure in the abdomen area to improve respiratory system function.
