Avoid Intubation with CPAP
Non-invasive Ventilation Modes (NIV)
If the patient is breathing spontaneously, you can avoid emergency intubation and the risks associated with it by using non-invasive ventilation. Non-invasive ventilation has proved successful in certain symptoms; this refers to mask ventilation without intubation or tracheotomy. The patient’s breathing is supported, they can continue to breathe spontaneously, and often do not need to be sedated at all or only very lightly – they remain responsive.
A typical indication for NIV therapy in an out-of-hospital environment is acute shortness of breath e.g. exacerbated COPD, asthma, or pulmonary edema.
MEDUMAT Transport and MEDUMAT Standard² have an integrated CPAP mode and additional ventilation modes which can be used for non-invasive ventilation. In CPAP therapy, positive airway pressure is continuously maintained. The combination with ASB (assisted spontaneous breathing) allows for pressure support during inhalation to be switched on.
The CPAP mode is integrated into the MEDUMAT Transport and MEDUMAT Standard².
In MEDUMAT Transport, the additional NIV function can be activated in all pressure-controlled modes. This deactivates the leakage alarm and MEDUMAT Transport uses accordingly optimized trigger algorithms. This function is not necessary for MEDUMAT Standard².
Oxygen therapy, during which the patient inhales oxygen without breathing support by means of a mask or nasal cannula, is possible with all WEINMANN medical ventilators. In the demand or pre-oxygenation function, oxygen is saved during inhalation, as the oxygen is exclusively administered during inhalation.
In MEDUMAT Transport and MEDUMAT Standard², the following ventilation modes can be administered via the mask as non-invasive ventilation methods:
CPAP (continuous positive airway pressure)
CPAP + ASB (continuous positive airway pressure + assisted spontaneous breathing)
BiLevel + ASB, aPCV and PCV
Continuous Positive Airway Pressure
The set value CPAP/PEEP is used to increase the pressure level of respiration in order to raise the functional residual capacity (FRC) of a spontaneously breathing patient. The patient is able to breathe spontaneously without any restriction at the set pressure level. The CPAP mode is used exclusively on patients with adequate spontaneous breathing.
CPAP + ASB
Continuous Positive Airway Pressure + Assisted Spontaneous Breathing
The CPAP + ASB mode can be separated into its individual elements:
- The set value CPAP/PEEP is used to increase the pressure level of respiration in order to raise the functional residual capacity (FRC) of a spontaneously breathing patient.
- The ASB function is used for pressure support of insufficient or exhausted spontaneous breathing. The patient is able to breathe spontaneously without any restriction, but is supported in their breathing effort by the device.
Demand Flow Mode
For MEDUMAT EasyCPR
In the demand flow position, MEDUMAT EasyCPR is switched to breathing-controlled O2 inhalation. Inhalation can be carried out using the ventilation mask. A low inhalation (trigger) pulse causes oxygen to continue flowing until a slight overpressure interrupts the flow; expiration then takes place via the patient valve as in ventilation. Inhalation takes place with the following settings:
Trigger: < 1 mbar
Peak flow: > 40 l/min
Switch-off pressure: 3 mbar
These settings cannot be changed.
