The respiratory centre of newborns is not fully developed, the cough reflex is weak (puffing milk, eating may cause asphyxia), the pectoralis diaphragm muscle is weak, and the lung surface-active material is insufficient. Compared with adults, the respiratory status of newborns requires close attention. If it is found that the newborn is suffering from hypoxia during delivery, it is necessary to closely monitor neonatal blood oxygen status after the baby is discharged from the hospital to avoid severe hypoxia and affect the normal development of the baby.

Causes of Neonatal Hypoxia

· Reasons from Internal Medicine Perspective

Pneumonia, aspiration syndrome (meconium, amniotic fluid, blood, milk), wet lung, atelectasis, pulmonary hemorrhage, lung dysplasia, apnea, emphysema, interstitial emphysema, non-surgical upper airway obstruction (small Jaw deformity, back tongue, obstruction, laryngotracheal softening), non-surgical abdominal distension; congenital heart disease with or without heart failure, shock (infectious, hypovolemic, hemorrhagic), polycythemia; central nervous system System abnormality etc.

· Reasons from Surgical Perspective

Pneumothorax, diaphragmatic hernia, oesophagal atresia with or without distal oesophagal-tracheal fistula, pleural effusion (empyema, chylothorax, hemothorax), congenital emphysema, lung cyst or mass, upper respiratory tract or mediastinum or lung tumour, upper respiratory tract obstruction, etc.

For newborns with the above symptoms, it is recommended to pay close attention to the neonatal blood oxygen level after discharge.

Manifestation of Neonatal Hypoxia

Neonatal hypoxia is mainly manifested as ①Breathing faster or slower; ② Deep or superficial breathing: infants or newborns can manifest as mouth breathing, groaning, nasal agitation (nostrils closed in one piece), and nodding breathing; ③Lips, the complexion turns purple or grey; ④The suprasternal fossa is sunken. The standard for increasing respiratory rate is: under the condition of calm and no oxygen inhalation, less than 2 months old ≥60 times/min, 2 months old-12 months old ≥50 times/min.

Usage of Neonatal Oximeter

The neonatal oximeter is designed to monitor the blood oxygen saturation and pulse rate of newborns. Arterial blood oxygen saturation is an important parameter reflecting the respiratory function and whether hypoxia. Hypoxia can cause many diseases and severely can lead to death. Real-time oxygen monitoring is especially important for the health of newborns.

How to Use Neonatal Oximeter?

The neonatal pulse oximeter is a non-invasive device for measuring blood oxygen saturation or pulse rate. It is easy to operate and suitable for hospitals and homes. In newborn oximeter testing, you only need to tie the neonatal blood oxygen probe to the outside of the baby’s dorsal foot. The arterial blood flow is relatively rich in this position. Because the newborn’s body movement will affect the blood oxygen measurement, you can use a strap to connect the probe data line. It is tied to the ankle to fix the probe and reduce the shaking of the sensor, which can monitor the baby’s blood oxygen status for a long time.
