How long will it take to recover from persistent pulmonary hypertension in the neonate (PPHN)?

After treatment for pulmonary hypertension, your baby’s lungs will take weeks or even months to recover fully. It will be important to help protect your baby from catching colds or flu bugs. You can help with this by practicing good hand washing and keeping your baby away from sick people and large crowds. It will also be especially important for your baby to see his or her pediatric healthcare provider and other specialists regularly to be screened for normal developmental milestones.
