Neonatal resuscitation in the delivery room

The first minutes after birth can determine whether a newborn transitions safely from placental oxygenation to independent breathing. Most infants need only routine care, such as drying, warmth, and observation. A smaller group requires stimulation, respiratory support, or advanced resuscitation. For that reason, every birth setting needs a prepared team, reliable equipment, and a shared response plan.

Delivery-room practice is guided by recommendations from organizations such as the International Liaison Committee on Resuscitation (ILCOR), the American Heart Association, the American Academy of Pediatrics, and national neonatal societies. These guidelines are updated as evidence develops, but their central priorities remain consistent: prevent heat loss, assess breathing and heart rate, establish effective ventilation, and use chest compressions or medication only when indicated.

Perinatal teams also need to recognize that resuscitation does not end when the infant begins breathing. Babies who have experienced prolonged hypoxia, difficult transition, or extensive assisted ventilation require continued observation and careful assessment for neurological injury, respiratory problems, glucose abnormalities, and temperature instability.

Preparation begins before birth

A short prebirth briefing improves performance when the situation becomes urgent. The team should review gestational age, fetal condition, labor complications, meconium, multiple pregnancy, maternal medication exposure, and the likelihood of preterm delivery. This information helps determine who should attend and what equipment should be prepared.

At least one trained professional should be capable of providing positive-pressure ventilation. Higher-risk births may require personnel skilled in intubation, umbilical venous access, chest compressions, and medication administration. Roles should be assigned in advance, including airway management, monitoring, medication preparation, documentation, and communication with the family.

Equipment checks should take place before every delivery. The warmer must be functioning, towels and hats should be available, and the team should confirm access to appropriately sized masks, a self-inflating bag or T-piece resuscitator, suction equipment, oxygen and air blending, pulse oximetry, cardiac monitoring, and emergency vascular-access supplies. For preterm infants, plastic wraps, thermal mattresses, and carefully controlled respiratory support may be needed to reduce heat loss.

The first assessment guides immediate care

At birth, the initial assessment asks three practical questions: Is the baby term? Is the infant breathing or crying? Is muscle tone appropriate? If the answers are reassuring, routine care can usually occur skin-to-skin with the parent, provided the infant remains warm and is monitored appropriately.

Routine care includes drying, maintaining warmth, positioning the airway, and observing breathing and color. Unnecessary suctioning should be avoided. Suction is reserved for obstruction or clear difficulty managing secretions; routine oral and nasal suction can cause bradycardia, mucosal injury, or delayed ventilation.

If breathing is absent, gasping, or ineffective, or if tone is poor, the infant should receive prompt support under a radiant warmer or through an appropriate thermal strategy. Gentle stimulation may be provided while positioning the head in a neutral or slightly extended “sniffing” position. The priority is not prolonged stimulation but rapid recognition of ineffective breathing and timely ventilation.

Heart rate is the most important indicator of response to resuscitation. It can be assessed by auscultation initially, with electrocardiographic monitoring providing a rapid and reliable measurement when advanced support is needed. A pulse oximeter placed on the right hand or wrist gives preductal oxygen saturation and helps the team adjust oxygen gradually rather than relying on color alone.

Ventilation is the central intervention

For a newborn who is apneic, gasping, or has a persistently low heart rate, positive-pressure ventilation should begin without unnecessary delay. The mask must fit over the nose and mouth without covering the eyes or pressing on the soft tissues beneath the chin. A neutral head position, a good seal, and visible chest movement are essential indicators that air is entering the lungs.

Current neonatal algorithms generally begin with room air for term and late-preterm infants, while preterm infants may require a carefully titrated oxygen concentration according to local guidance and oxygen-saturation targets. Excess oxygen can contribute to oxidative injury, so oxygen should be adjusted using pulse oximetry whenever possible.

If the heart rate does not rise, the team should troubleshoot ventilation before escalating treatment. Common problems include a poor mask seal, an obstructed airway, incorrect head position, insufficient pressure, or a need for an alternative airway. Repositioning the mask, opening the airway, clearing an obstruction when present, and increasing pressure cautiously may restore effective ventilation.

An endotracheal tube or laryngeal mask may be considered when mask ventilation is ineffective, prolonged ventilation is expected, or chest compressions are required. Intubation should be performed by a trained clinician, with confirmation of placement through clinical assessment and exhaled carbon dioxide detection where available. Ventilation remains the intervention most likely to correct newborn bradycardia caused by respiratory failure.

When compressions and medication are justified

Chest compressions are considered when the heart rate remains below 60 beats per minute after at least 30 seconds of effective ventilation that visibly moves the chest. Starting compressions before correcting ventilation can delay the treatment of the underlying problem, so the team should verify airway support first.

The preferred technique is coordinated two-thumb compressions over the lower third of the sternum, using a depth of approximately one-third of the chest’s anterior-posterior diameter. Compressions are coordinated with ventilation in a three-to-one ratio, producing 90 compressions and 30 breaths per minute. A secured airway and 100% oxygen are commonly used during this advanced stage, with oxygen concentration adjusted after the heart rate improves according to local protocol.

If the heart rate remains below 60 beats per minute despite effective ventilation and coordinated compressions, epinephrine may be indicated. Intravenous or intraosseous access is preferred where available, and an umbilical venous catheter is often the most practical emergency route in the newborn. Volume expansion may be considered when blood loss or hypovolemia is suspected, rather than administered routinely.

The team should document the timing of each intervention, heart-rate response, oxygen concentration, airway device, medication dose, and vascular-access route. Clear records support clinical handover, quality review, and communication with parents.

Special considerations for preterm infants

Premature newborns have a higher risk of respiratory distress, hypothermia, apnea, and cardiovascular instability. Their thin skin and limited fat reserves make temperature management especially important. A preterm infant who is breathing may benefit from continuous positive airway pressure rather than routine intubation, depending on respiratory effort, gestational age, oxygenation, and the unit’s protocol.

Thermal care begins immediately. The delivery room should be warm, wet towels should be replaced with dry materials, and very preterm infants may be placed in a polyethylene wrap without drying. A hat, warmed gases when available, and careful monitoring can further reduce heat loss. Both hypothermia and hyperthermia are associated with poorer outcomes, so temperature should be measured and managed deliberately.

Delayed cord clamping may be appropriate for many vigorous preterm and term infants, offering potential circulatory benefits. When immediate resuscitation is required, the clinical team must balance the value of placental transfusion with the need to provide effective support. Umbilical cord milking is subject to gestational-age considerations and local recommendations, particularly in extremely preterm infants.

Respiratory support should use the lowest effective oxygen concentration, guided by preductal saturation targets and clinical response. Excessive airway pressure can injure immature lungs, while inadequate support can prolong hypoxia. A neonatal team should be ready to transfer the infant to intensive care when ongoing respiratory support, intravenous therapy, or close neurological observation is needed.

Neurological protection continues after stabilization

Once spontaneous circulation and adequate breathing are established, care shifts toward preventing secondary injury. The newborn should remain warm, with glucose checked when risk factors are present. Recurrent apnea, seizures, abnormal tone, poor consciousness, metabolic acidosis, and unstable oxygenation require prompt evaluation.

Infants with moderate or severe hypoxic-ischemic encephalopathy may be candidates for therapeutic hypothermia when they meet gestational-age, timing, neurological, and biochemical criteria. Cooling should follow an established protocol and begin within the relevant treatment window, usually under specialist guidance. It should never replace effective ventilation, circulation support, or treatment of hypoglycemia and other reversible problems.

The relationship between early resuscitation and later neurological outcome is complex. The duration of low heart rate, quality of ventilation, acid-base status, seizures, and evidence of organ dysfunction all contribute to prognosis. Families need clear, compassionate explanations about what is known, what remains uncertain, and which assessments will follow. Clinicians who want wider background on neurological outcomes can review material on neonatal encephalopathy biomarkers and their potential prognostic role.

Communication is part of clinical care. A designated team member should update parents during or soon after resuscitation, explain the interventions used, and describe the infant’s current condition. When transfer to a neonatal unit is required, the handover should include the initial status, Apgar scores, ventilation details, oxygen exposure, heart-rate response, medications, temperature, glucose, and concerns about neurological injury.

Building reliable team performance

Neonatal resuscitation guidelines are most effective when translated into repeated practice. Simulation training allows teams to rehearse airway support, closed-loop communication, equipment troubleshooting, and escalation to compressions without exposing patients to avoidable risk. Debriefing after real or simulated events can identify delays, unclear responsibilities, or equipment problems.

Standardized checklists support preparation, especially during preterm birth, shoulder dystocia, maternal hemorrhage, or unexpected fetal compromise. They should be short enough to use under pressure and adapted to the resources of the delivery unit. A checklist cannot replace clinical judgment, but it reduces omissions during a rapidly changing event.

Hospitals should monitor process measures such as time to first ventilation, use of oxygen, intubation success, chest-compression frequency, admission temperature, and unplanned transfers. Reviewing these data alongside clinical outcomes helps distinguish individual performance issues from system problems, such as inadequate staffing, missing equipment, or delayed access to specialists.

Healthcare professionals should use the current guidance adopted by their institution and participate in accredited neonatal resuscitation training. The FAOPS 2020 resource reflects the wider perinatal and neonatal medicine community in which evidence, education, and international collaboration shape care standards.

Practical priorities for delivery-room teams

• Assign trained roles and complete an equipment check before every high-risk birth.
• Start effective ventilation promptly when breathing is absent, gasping, or inadequate.
• Use heart rate, chest movement, and preductal oxygen saturation to guide escalation.
• Protect temperature, glucose balance, and oxygen exposure after initial stabilization.
• Document the event clearly and provide a structured handover to neonatal care.

A well-prepared delivery-room team combines technical skill with disciplined assessment. The safest approach is to intervene according to the infant’s response, correct ventilation problems before escalating, and maintain close observation after apparent recovery. Applying current neonatal resuscitation guidance consistently gives newborns the strongest possible start while supporting families through an intense and uncertain moment. Teams should review their local protocol, rehearse it regularly, and keep training aligned with the latest evidence from recognized neonatal authorities.
