1.RR in tachypnea? -The normal respiratory rate (RR) for adults at rest is typically in the range of 12 to 20 breaths per minute. Tachypnea is generally defined as a respiratory rate that exceeds this normal range, that is respiratory rate higher than 20 breaths per minute in adults considered tachypneic. 2.why there is tachypnea in community acquired pneumonia (CAP)despite a normal SpO2 reading of 99% ? Reasons for tachypnea in CAP: Ventilation-Perfusion Mismatch: Pneumonia can lead to a mismatch between ventilation (airflow) and perfusion (blood flow) in the lungs. Even with adequate oxygen levels in the inhaled air, the exchange of gases in the affected areas of the lungs may be compromised, triggering a respiratory response. Increased Work of Breathing: The body's effort to overcome the decreased lung function and maintain sufficient oxygen supply to the bloodstream can result in tachypnea, despite the overall oxygen saturation appearing normal. 3.Respiratory findings in Com
