The respiratory rate, tidal volume and ventilation were measured in newborn infants with a body plethysmograph. A continuous recording revealed that, with one exception, no significant change occurred in these parameters when seven mature infants were turned from supine to prone position or vice versa. Two mature infants with periodic breathing, one of whom had congenital heart disease, exhibited periods of apnea when placed from the supine into the prone position.

Relative Inability

The effects of administering atmospheres containing 10 and 12% oxygen to healthy newborn infants of different ages have been studied. Infants under 24 hours of age tended to hypoventilate throughout the period of hypoxia. Infants six to 11 days of age hyperventilated for the first two or three minutes and then showed a decrease, although not so marked as observed in the infants under 24 hours of age. Infants 16 to 48 days of age showed the most marked increase in ventilation, but even in these infants it was poorly maintained as compared to responses seen in adults. Hypoxia produced a slowing of the respiratory rate in all infants except the very oldest. Tidal air was increased at first and then decreased. The increases in tidal air accounted for most of the increase in minute volume seen in the older infants. Hypoxia increased the incidence of periodic breathing in the two older groups of infants, but had very little effect on infants under 24 hours of age. Respiratory patterns did not appear to be altered by the hypoxic conditions employed in this study. It has been postulated that the comparatively weak response to hypoxia made by infants immediately after birth possibly is dependent on relatively poor chemoreceptor reflexes and that the latter increase in strength during the first weeks of postnatal life. It has also been suggested that the relative inability to induce periodic breathing in infants under 24 hours of age as compared to those several weeks old is further evidence indicating that metabolism of the medullary respiratory centers is to a larger extent anerobic than at the later periods of postnatal life.

Hypoxic State

The response to breathing 12 per cent oxygen by newborn premature and full-term infants and premature infants several weeks old has been studied. Comparisons show that newborn premature and full-term infants during the first days after birth failed to respond with increases in respiratory rate or tidal volume during the hypoxic state. In fact, there was some decrease in ventilation which was largely related to reductions in tidal volume. Premature infants several weeks old, on the other hand, showed an immediate and significant hyperpnea while breathing 12 per cent oxygen. The younger infants, particularly the premature infants, seemed to be less disturbed by the hypoxia than older infants. These results substantiated previous results obtained on full-term infants. The hypothesis was advanced that the chemoreceptor reflexes were less active immediately following birth than later on in life.

Definite Effect

Values for respiratory rates in the supine and prone positions in 96 premature and 49 full-term infants have been presented. Premature infants have a significant increase in respiratory rate in the prone position compared to the supine position. This difference decreases with increasing weight and age. Mature infants show a slight increase in respiratory rate in the prone compared to the supine position. The position of the premature infant has a definite effect on the physiology of respiration. Further studies must be done to establish whether the supine or prone position is superior. Irregularity of rate and amplitude of respirations are noted in the supine position, while respirations of regular rate and amplitude are frequently found in the prone position. The amplitude of respiration was greater in the supine position than in the prone position.

Early Warning Scores

Tools for clinical assessment and escalation of observation and treatment are insufficiently established in the newborn population. We aimed to provide an overview over early warning- and track and trigger systems for newborn infants and performed a nonsystematic review based on a search in Medline and Cinahl until November 2015. Search terms included ‘infant, newborn’, ‘early warning score’, and ‘track and trigger’. Experts in the field were contacted for identification of unpublished systems. Outcome measures included reference values for physiological parameters including respiratory rate and heart rate, and ways of quantifying the extent of deviations from the reference. Only four neonatal early warning scores were published in full detail, and one system for infants with cardiac disease was considered as having a more general applicability. Temperature, respiratory rate, heart rate, SpO2, capillary refill time, and level of consciousness were parameters commonly included, but the definition and quantification of ‘abnormal’ varied slightly. The available scoring systems were designed for term and near-term infants in postpartum wards, not neonatal intensive care units. In conclusion, there is a limited availability of neonatal early warning scores. Scoring systems for high-risk neonates in neonatal intensive care units and preterm infants were not identified.

Serial Measurements

Serial measurements have been made of the resting tidal and minute volumes and respiratory rates on 40 premature infants during the first 2 weeks after birth. The 40 infants were divided into three groups according to the trend of their respiratory rates. Infants whose respiratory rates were normal from birth (Group I) had the highest mean resting tidal volumes during the first 2 weeks. Mean resting tidal volumes were significantly lower throughout the first week among infants whose respiratory rates were initially high during the first hour and subsequently declined to normal (Group II) and among infants whose respiratory rates significantly increased after the first hour (Group III). Infants in Group III had the lowest tidal volumes and the most severe degrees of respiratory insufficiency. The mean resting tidal volume among infants in Group III was less at the end of the first week than that of infants in Group I at the end of the first day. Although tidal volumes in infants in Group II were in general much lower than normal the first few days after birth, exceptions to this rule may occasionally be encountered. Although all three groups showed an increase in mean tidal volumes of about 25% at the end of 24 hours over the volumes obtained during the first 3 hours after birth, the respiratory rates were different. In Group I the increase in tidal volume was accompanied by no significant change in respiratory rate; in Group II, by a significant decrease in respiratory rate; in Group III, by a significant increase in respiratory arte. During the second day Group III showed clinical improvement accompanied by a significant decrease in mean respiratory rate but not by any significant increase in mean tidal volume. Fluctuations in mean minute volumes in Groups II and III on the first 2 days were largely dependent on changes in respiratory rates.
