Shortness of breath

The prevalence of pneumonia in prenatal infections is mostly within 3 to 7 days after birth. Symptoms are often atypical, and the symptoms are less typical at younger gestational ages, with about half of those with normal body temperature, and the rest with unstable body temperature. The temperature of severely sick or premature babies is usually not high. Symptoms are mostly non-characteristic manifestations such as antifeeding, lethargy, or irritability, poor complexion, no weight gain, and no cough. Shortness of breath, nasal flaps, moaning, soft tissue depression during inhalation, and heart rate increase quickly. Premature babies are prone to apnea, and lung signs have increased or decreased breathing sounds with dry or wet snoring sounds, but may also be completely negative. Various pneumonias that occur after birth start later, with more typical symptoms, such as nasal congestion, cough, shortness of breath, and often fever in term infants, but they can also have normal body temperature, and premature infants may not have a high temperature. Wet sounds of varying thickness can be heard in the lungs. With empyema or pneumothorax, respiratory sounds are reduced, dullness or reverberation is enhanced on percussion, and pneumonia caused by various pathogens has some characteristics.
