Baby nasal aspirators to remove nasal mucus are generally of three types: 1) Bulb syringe 2) Battery-powered and 3) Self-suctioning. The last type is regarded as the most effective because, by using your own suction, you can effectively generate greater and more consistent suction. Self-suctioning type aspirators are designed so that mucus is captured in a receptacle or a filter so that the operator (most often a parent) is not exposed to mucus and germs.
Hospitals send new parents home with a traditional bulb syringe nasal aspirator, however, they are not necessarily the best tool for the job. The main drawback of the bulb syringe aspirator is that because the bulb is of limited size, it can only generate limited suction. This requires that the bulb be inserted into the nostril of the child repeatedly in order to remove mucus. This is difficult with a child that will inevitably be squirming and can cause damage to the delicate nasal membranes.
We have tested all available battery-operated nasal aspirators on the market today and generally find them to be ineffective for the reason that they do not generate sufficient suction. A battery-powered vacuum pump is not generally strong enough to remove mucus that is deeper inside the sinus cavity, and this is the mucus that is most important to remove.
Baby nasal aspirators that employ self-suctioning have the advantage that the amount of suction that can be generated is limited only by the lung capacity of the operator. Here we would like to address some of the typical concerns that parents have regarding self-suctioning baby nasal aspirators:
Concern: I will catch my child's cold using a self-suctioning aspirator.
Response: Virus and bacteria are water-borne, they can only be spread if they are contained in droplets of water or mucus. Properly designed self-suctioning aspirators are designed expressly to prevent the passage of droplets through the suction tube. In addition, self-suctioning aspirators generally employ filters to catch liquid droplets.
Concern: I will generate too much suction and injure my child.
Response: We only need consider the relatively large pressures generated by sneezing, which can exceed velocities of 100 miles per hour. Compared to this the pressure generated by a parent suctioning is relatively low, on the order of 1/10th the velocity and therefore pressure. In other words, the human body is designed to withstand and indeed generate significantly more sinus pressure than is created in the nasal suctioning process.
