Final answer:
An increased respiratory rate in a severely injured patient should not be ignored as it signifies a change in their respiratory function, potentially indicating hypoxemia or increased metabolic demand. Constant monitoring and reassessment are paramount, along with appropriate interventions which could include oxygen therapy and advanced airway management.
Step-by-step explanation:
If a patient's respiratory rate has increased during transport to a trauma center, it suggests a potential change in their condition that should not be ignored. The increase in respiratory rate can indicate a compensatory response to hypoxemia, shock, pain, or other causes of increased metabolic demand. It is vital to continually monitor the patient, reassessing their vitals, and providing appropriate interventions as necessary.
Biologically, the respiratory rate is controlled by the medulla oblongata, adjusting in response to changes in carbon dioxide, oxygen, and pH levels in the blood. In cases where ventilation is low (inadequate oxygen intake or carbon dioxide removal), the respiratory rate and volume can change in different ways. For example, hyperpnea is an increase in rate and depth of respiration typically initiated by neural mechanisms in response to exercise or other stimuli requiring more oxygen or carbon dioxide expulsion.
In the clinical scenario where a patient has a high respiratory rate with decreased volume per breath, this may signal restrictive breathing patterns commonly seen in conditions such as tension pneumothorax, pulmonary edema, or severe asthma attacks. In such situations, immediate medical actions, such as administering oxygen, positioning the patient to facilitate easier breathing, or preparing to perform advanced airway management procedures, could be necessary.
