The LUISA ventilator by Löwenstein Medical is a modern, portable device designed for both invasive and non-invasive ventilation. It is widely used in home care and hospital settings to support patients with respiratory conditions such as COPD, neuromuscular disorders, and chronic respiratory failure.

Understanding the correct ventilator settings is essential to ensure safe, effective, and comfortable breathing support.

1. Ventilation Mode

• CPAP – Continuous pressure for sleep apnea
• BiPAP (S/T mode) – Different pressure for inhale/exhale
• Pressure Control (PCV) – Controlled pressure delivery
• Volume Control (VCV) – Fixed volume per breath

The mode depends on the patient’s condition and doctor’s recommendation

2. Inspiratory Pressure (IPAP)

• Controls the pressure during inhalation
• Helps improve airflow into lungs
• Common range: 10–25 cmH₂O

3. Expiratory Pressure (EPAP)

• Maintains airway pressure during exhalation
• Prevents airway collapse
• Common range: 4–10 cmH₂O

4. Respiratory Rate (RR)

• Number of breaths delivered per minute
• Usually set between 10–20 breaths/min

5. Tidal Volume (VT)

• Amount of air delivered per breath
• Typically based on patient weight

6. FiO₂ (Oxygen Level)

• Percentage of oxygen delivered
• Adjusted based on patient oxygen saturation

7. Rise Time

• Controls how quickly pressure increases
• Lower = faster delivery, Higher = smoother comfort

8. Trigger Sensitivity

• Detects patient’s breathing effort
• Ensures synchronization with ventilator

Using LUISA at home is simple when guided by professionals:

1. Device placement near the patient
2. Connect tubing and mask
3. Set prescribed parameters
4. Ensure proper mask fit (no leakage)
5. Monitor oxygen levels and comfort

Always follow instructions from healthcare providers.

✔ Never change settings without medical advice
✔ Regularly clean mask and tubing
✔ Check alarms and battery backup
✔ Monitor patient comfort and breathing
