In cases of cardiovascular distress, which of the following is vital to monitor?

Monitoring in cases of cardiovascular distress is crucial to ensure patient safety and facilitate timely medical intervention. Each of the listed parameters provides essential information about the patient's cardiovascular status.

Patient weight is less relevant in acute situations of cardiovascular distress; however, it can be useful in the broader context of managing conditions like heart failure, where fluid retention can lead to significant weight changes.

Heart rhythm is a critical measure because irregularities may indicate arrhythmias, which can compromise cardiac function and require immediate intervention.

Oxygen saturation is also vital as it indicates how well oxygen is being transported in the blood, which is essential in cardiovascular distress. Low oxygen saturation can lead to hypoxia, which exacerbates cardiovascular problems and can quickly become life-threatening.

Collectively, monitoring heart rhythm and oxygen saturation makes it imperative to keep tabs on the patient’s overall status. Hence, incorporating all these indicators provides a comprehensive understanding of the patient's condition, making monitoring all of them vital in cases of cardiovascular distress.
