Brief Summary

Oxygen treatment is common in babies born early (preterm) and requiring intensive care. Having too much or too little oxygen can increase the risk of damage to the eyes and lungs, and contribute to death or disability. Preterm infants because of their immaturity experience episodes of low oxygen levels. The low oxygen episodes are primarily due to pauses in their breathing (Apnoea of prematurity) and immaturity of their lung. These episodes persist for weeks to months. The lower the gestation at birth the longer the duration of these events. Studies have shown that these episodes of low oxygen saturations especially if frequent and prolonged is associated with poor developmental outcome, severe eye disease and lung disease. Traditionally, the oxygen delivery is manually adjusted when infant has low oxygen saturation. However previous studies have shown despite the best efforts the oxygen level can only be maintained less than half of the time and nearly a one-fifth of the time infant spends in low oxygen levels and nearly one-third of the time in high oxygen levels. With advancement in the neonatal care, preterm infants tend to spend more time on non invasive respiratory support. Now it is possible to maintain oxygen level in target range by using automatic control of oxygen delivery on non invasive support. With the proposed study, we would like to study the efficacy of automatic control of oxygen delivery in reducing the time spent in very low and high oxygen levels when infants are on non invasive respiratory support namely High Flow Nasal Cannula support.

Outcome Measures

Primary Outcomes (1)

  • Proportion of time spent in extreme saturation (<80% and >98%) in preterm infants receiving HFNC as respiratory support.

    The primary outcome of this study is proportion of time spent in extreme saturation (\<80% and \>98%) in preterm infants receiving HFNC as respiratory support.

    Through study completion on an average of 3 months

Secondary Outcomes (3)

  • Proportion of time spent in target saturation

    Through study completion on an average of 3 months

  • Proportion of time spent in saturation >95%

    Through the study completion on an average of 3 months

  • episodes of prolonged hypoxemia (SpO2 < 80% for more than 60 sec)

    Through study completion on an average of 3 months

Study Arms (2)

Automatic control of FiO2

EXPERIMENTAL

Infants randomized to this arm will be monitored using automatic oxygen control system on the High Flow Nasal Cannula. When infants oxygen saturation are out of the target range the OAM module on HFNC will adjust the oxygen delivery depending on the saturation of the infant to bring the saturation in the target range.

Device: High Flow Nasal Cannula withAutomatic control of FiO2 using OAM

Manual Control of FiO2

ACTIVE COMPARATOR

Infants randomized to this arm will be receive oxygen delivery adjustments manually by the nursing and medical team taking care of the infants. When the infants oxygen saturation are out of the target range, the staff will manually adjust the oxygen delivery.

Device: High Flow Nasal Cannula with manual control of FiO2

Interventions

The target oxygen saturation (SpO2) value will to be determined and set by the clinician according to specific patient needs. The target SpO2 in preterm infants is 90-95% with alarm limits at 89-96%. In automatic control of oxygen, the OAM automatically increases or decreases the FiO2 (oxygen delivery) setting on the Vapotherm Precision Flow based on pulse oximetry readings of the OAM. The target saturation will be set at 93% and the FiO2 will be adjusted by OAM to maintain the target saturation. The automated FiO2 setting can be overridden for a clinician pre-set period of time (30-120 sec) by simply manually adjusting the FiO2 on the Precision Flow. Automated control resumes after the clinicians pre-set period of time (30-120 sec) based on the current SpO2 and FiO2. The OAM utilizes a feedback control algorithm that receives a patient's oxygen saturation value from a build in pulse oximetry device (Masimo SET OEM - normal sensitivity, averaging time window set at 8 seconds).

Automatic control of FiO2

In manual control of oxygen all FiO2 adjustments will be done by the clinical staff to maintain saturations between 90-95%. The alarm limits will be 89-96%.

Manual Control of FiO2
