1. What is Neopuff?
The Neopuff is a T-piece resuscitator designed specifically for the resuscitation and stabilization of newborns. Unlike manual resuscitation bags, the Neopuff offers a PIP and one PEEP constant and controlled, which minimizes the risk of barotrauma y volutrauma pulmonary.
Neopuff Key Features
Precise control of PIP: Ensures that each breath delivered does not exceed a safe pressure limit.
PEEP constant: It helps keep the alveoli open, improving gas exchange and oxygenation.
Consistent inspiration time: Controlled by the operator through T-piece occlusion.
Integrated pressure gauge: Allows continuous visual monitoring of pressures.
It is an essential tool in the delivery room and neonatal intensive care units, allowing more physiological and safe ventilation for the delicate lung of the newborn.
Considerations about Masks and Types:
The Neopuff is used with different sizes of face masks or nasal cannulas, depending on the size and condition of the newborn. Selecting the proper mask is crucial to ensure a tight seal and effective ventilation, minimizing leaks and optimizing pressure delivery.
2. Neopuff Indications
The Neopuff is indicated in situations where the newborn requires positive pressure ventilatory support. The main indications include:
Apnea: When the newborn is not breathing or has ineffective respirations for a prolonged period.
Hypoxia: Low blood oxygen levels (SpO2 low) that do not improve with supplemental oxygen or CPAP.
Neonatal Resuscitation: As part of the advanced resuscitation algorithm, especially when controlled positive pressure ventilation is required.
Respiratory Distress Syndrome (RDS): Can be used to provide PEEP and improve oxygenation in infants with RDS, although CPAP is often preferred in stable situations.
Post-Intubation Stabilization: To maintain ventilation with controlled parameters after endotracheal intubation.
Remember!
The decision to use Neopuff should be based on rapid clinical evaluation and compliance with neonatal resuscitation algorithms. Proper training is essential.
3. Configuration and Initial Parameters
Before using the Neopuff, it is crucial to set it up correctly and establish the appropriate initial parameters for the newborn. Proper preparation ensures effective and safe resuscitation.
Configuration Steps
Connect to gas source: Connect the Neopuff to a source of compressed air or oxygen (or a mixture of both) with a flow rate of 8 to 10 liters per minute (LPM).
Connect the circuit: Make sure all circuit connections are tight, with no leaks.
Adjust the PIP maximum (relief valve): Set the pressure relief (pop-off) valve to a safe maximum, usually around 30-40 cmH2O, to avoid accidental excessive pressures.
Adjust the PEEP: Turn the control PEEP to establish a PEEP initial 5 cmH2O.
Adjust the PIP desired: Adjust the control PIP for a maximum initial inspiratory pressure of 20-25 cmH2O. This will be adjusted based on the baby's response.
Check operation: Occlude the end of the circuit and observe the pressure gauge. When occluding and deoccluding, pressures must fluctuate between PEEP established and the PIP desired.
Typical Initial Parameters:
Gas Flow: 8 - 10 L/min
PIP (Maximum Inspiratory Pressure): 20 - 25 cmH2O (adjust to see chest movement)
PEEP (Positive Pressure at the End of Expiration): 5 cmH2O
Remember that these are initial parameters and should be adjusted immediately according to the clinical response of the newborn, evaluating chest movement, heart rate and oxygen saturation.
4. Modification of Parameters according to the Patient's Status
Adjusting the parameters of the Neopuff is a dynamic process that depends on the response of the newborn. Continuous monitoring and rapid adaptation are key to effective and safe ventilation.
Setting PIP (Maximum Inspiratory Pressure):
Increase PIP: If there is no visible chest movement or heart rate and SpO2 do not improve, it may be necessary to increase the PIP in increments of 2-3 cmH2O until adequate chest expansion is obtained. The goal is a gentle, visible elevation of the chest.
Decrease PIP: If there is excessive chest expansion or signs of lung overdistension (for example, difficulty exhaling, deterioration of SpO2 paradoxical), the PIP should be reduced.
Setting PEEP (Positive Pressure at the End of Expiration):
Increase PEEP: It can be increased if oxygenation is insufficient despite a PIP adequate, to improve alveolar recruitment or prevent lung collapse. Increase by 1-2 cmH2O, up to a maximum of 8-10 cmH2O in specific cases.
Decrease PEEP: Consider reducing PEEP if there is significant air trapping or if the aim is to facilitate weaning from ventilatory support.

Constant Monitoring:
While using the Neopuff, it is essential to monitor:
Thoracic Movements: Observe the smooth and symmetrical elevation of the chest.
Heart Rate: Should increase to >100 bpm with effective ventilation.
Oxygen Saturation (SpO2): Monitor with a pulse oximeter to ensure adequate oxygenation.
Skin Coloration: Observe changes in color (cyanosis).
Respiratory Sounds: Assess air entry bilaterally.
Key Principle:
Always use the minimum effective pressure and inspiratory time to achieve adequate ventilation and oxygenation, thus minimizing the risk of lung damage.
5. Retirement Criteria and Weaning Process
The process of removing Neopuff, also known as weaning, should be done gradually and only when the newborn meets certain criteria. Premature or abrupt withdrawal can lead to relapse of respiratory distress.
Criteria to Start the Withdrawal
Effective Spontaneous Breathing: The newborn shows vigorous and regular respiratory efforts.
Stable Heart Rate: Heart rate >100 beats per minute consistently.
Adequate Oxygen Saturation:SpO2 within the target ranges for gestational age, with a FiO2 low.
Good Coloration: Pink skin without signs of cyanosis.
General Stability: Absence of apnea, bradycardia or signs of respiratory distress.
Neopuff Weaning Process
Gradual reduction of PIP: Once the baby is stable, the PIP It can be gradually reduced in increments of 1-2 cmH2O, allowing the baby to take on more work of breathing.
Maintenance of PEEP: The PEEP It is usually maintained at 5 cmH2O during weaning, as it is essential to keep the alveoli open and improve functional residual capacity. In some cases, it can be reduced to 4-3 cmH2O if the baby is very stable.
Observation: During the reduction process, the baby's response, heart rate, SpO2 and respiratory efforts.
Final Withdrawal: Once the PIP has been reduced to the effective minimum and the baby maintains adequate spontaneous ventilation with PEEP minimal (or no PEEP if the protocol allows it), the Neopuff can be removed.
Post-Withdrawal Monitoring: After device removal, the newborn should be closely monitored for any signs of recurrent respiratory distress. The use of nasal CPAP may be considered if necessary.
Key point:
Weaning should be a slow and careful process, adapted to the individual response of the newborn. Patience and constant monitoring are essential.

7. Common Problem Solving
Below are some common problems that may arise while using the Neopuff and how to quickly address them:
The desired pressures are not reached (PIP/PEEP)
Possible causes: Circuit or mask leaks, insufficient gas flow, incorrect adjustment of pressure controls PIP/PEEP.
Solutions:
Check the seal of the mask on the baby's face.
Check all circuit connections for leaks.
Ensures a gas flow of 8-10 L/min.
Reset the controls PIP y PEEP.
Erratic pressure gauge reading
Possible causes: Circuit obstruction, pressure gauge malfunction, intermittent leaks.
Solutions:
Check that there are no secretions or obstructions in the circuit or T-piece.
If you suspect a faulty gauge, replace the Neopuff with another one.
No chest movement despite adequate pressures
Possible causes: Airway obstruction (e.g. head position, secretions), poorly sealed mask.
Solutions:
Reevaluate the position of the head and neck to ensure opening of the airway.
Aspirate secretions if necessary.
Ensures an airtight seal of the mask.
Consider the need for intubation if ventilation does not improve.
