It is acquired outside the hospital. The most commonly identified pathogens are Streptococcus pneumoniae, Haemophilus influenzae, atypical bacteria (ie, Chlamydia pneumoniae, Mycoplasma pneumoniae, Legionella species), and viruses. Symptoms and signs are fever, cough, sputum production, pleuritic chest pain, dyspnea, tachypnea, and tachycardia. Diagnosis is based on clinical presentation and chest x-ray. Treatment is with empirically chosen antibiotics. Prognosis is excellent for relatively young or healthy patients, but many pneumonias, especially when caused by S. pneumoniae, Legionella, Staphylococcus aureus, or influenza virus, are serious or even fatal in older, sicker patients.

My pediatric patients in the hospital common diagnosis there are PCAP with different classifications. They're struggling, some are infants and unable to cope up but with help of health care professionals & their best patients are goin' better. It's fun interacting with them chika while taking vital signs also to establish rapport that their son/daughter is in good hands. At the end of the shift, feeling overwhelmed because new day new experience and knowledge.
