Child Car Safety Seats Can Deprive Babies of Oxygen

While child car safety seats are a must for newborns riding in cars, the seats can also cause a baby to experience breathing problems. Infants have to be placed in an upright position when in a child safety seat. However, according to a new study published in Pediatrics, this can cause the baby’s chest wall to become compressed, decreasing airway size and lowering oxygen levels in the blood.
T. Bernard Kinane, Massachusetts General Hospital’s chief of pulmonary pediatrics, says that 20% of newborns that are placed in car beds and car seats may experience mild respiratory compromise. This can increase the chances that an infant will experience breathing problems.
The study examined 200 healthy newborns. Each baby was placed in a car bed for 60 minutes, a hospital crib for 30 minutes, and a car seat for 60 minutes. The infants’ oxygen levels were lower when they were in the car beds and car seats than when they were in the hospital cribs. In a car seat, the babies’ average oxygen saturation level was 95.7%, 96.3% in a car bed, and 97.9% in a hospital crib.
This is important to note, as many parents will take the car seat out the vehicle and let their babies sleep in them. Researchers are now telling parents to only use car beds and car seats for travel and definitely not as a replacement for a child’s bed.
While some physicians have said that the side effects are relatively mild and long-term consequences are unlikely, Kinane is recommending that child safety seat makers redesign infant car seats so that chest compression doesn’t happen. He says that one way to do this is to install a new seat back and new buckles so that the baby’s head can fall back.
Selena Silva, of the Child Passenger Safety Program at Children’s Hospital, says that an infant car seat’s reclining angle should be at around 45 degrees to keep the baby’s airway open and prevent slumping. This angle has been crash-tested.
Child Safety Seats
The makers of child safety seats must make sure that their products are safe for use. This means that the seats will ensure the greatest amount of protection for babies and other young children during a car crash. A child car safety seat should also not be designed in a way that could cause a baby’s health to suffer. Manufacturers also need to warn of any possible injuries or health issues that may result from use.
If you think your child was injured or became sick because of the way a child car safety seat was designed, a car seat defect, or because the child car safety seat malfunctioned, you may have grounds for filing a products liability lawsuit.
