4 11.3 Brief Scan: Cardiovascular System
A brief scan provides a quick overview of the cardiovascular (CV) and peripheral vascular (PV) systems when the client enters the room. This initial assessment helps determine how the client may need support, any modifications required in further assessment, and identifies cues that warrant further investigation. Recognizing abnormalities early is crucial for timely intervention. If concerning findings arise, notify the provider, seek additional help, or activate rapid response as needed.
Step 1: Primary Survey – Circulation (C) Assessment
The primary survey focuses on circulation, evaluating signs of perfusion and cardiovascular function through inspection, palpation, and vital signs.
1. Inspection
-
Pallor: Observe for paleness in the face, lips, and nail beds, which may indicate anemia or poor circulation. In darker skin tones, assess for pallor in the conjunctiva, mucous membranes, and palms of the hands.
-
Cyanosis: Look for a bluish tint around the lips, fingertips, or extremities, suggesting hypoxia or inadequate oxygenation. In darker skin tones, cyanosis may appear as a gray or ashen discoloration, particularly around the mouth and nail beds.
-
Cold, Clammy Skin: Moist, cool skin may be a sign of shock or compromised perfusion.
-
Capillary Refill Time: Press and release the nail bed; if refill takes longer than 2 seconds, it suggests poor circulation. In darker skin tones, assess capillary refill by pressing on the palm or sole of the foot.
2. Palpation
-
Pulse Quality: Assess the radial, carotid, or femoral pulses for strength and regularity. Weak or thready pulses may indicate poor perfusion.
-
Pulse Rate: Measure the pulse and recognize tachycardia (>100 bpm) as a sign of shock, fever, or hypovolemia, or bradycardia (<60 bpm) as a possible sign of severe cardiovascular distress.
-
Skin Temperature: Cool skin suggests poor circulation, while warm, flushed skin may indicate fever or a hyperactive circulatory response.
-
Peripheral Edema: Check for swelling in the lower extremities. Pitting edema could suggest heart failure or venous insufficiency.
3. Vital Signs
-
Heart Rate (HR):
-
Tachycardia (>100 bpm): May indicate hypovolemia, pain, fever, or shock.
-
Bradycardia (<60 bpm): Could signal impending cardiac arrest or severe cardiovascular compromise.
-
-
Blood Pressure (BP):
-
Hypotension (SBP <90 mmHg): Suggests shock, dehydration, or cardiac failure.
-
Hypertension (SBP >180 mmHg, DBP >120 mmHg): Raises concerns for hypertensive crisis, stroke, or heart failure.
-
-
Respiratory Rate (RR):
-
Tachypnea (>20 breaths/min): May indicate cardiac failure or pulmonary edema.
-
Bradypnea (<12 breaths/min): Poses a risk for respiratory failure, especially with altered mental status.
-
-
Oxygen Saturation (SpO2):
-
SpO2 <90%: Suggests significant hypoxia, which may result from heart failure, pulmonary embolism, or severe anemia.
-
Conclusion
A brief cardiovascular and peripheral vascular scan allows nurses to quickly assess circulation and perfusion. Identifying abnormal findings early supports timely intervention and patient safety. If signs of cardiovascular compromise are present—such as severe hypotension, unresponsive bradycardia, or SpO2 dropping below 90%—notify the provider immediately, seek additional support, or activate the rapid response team.
Key Takeaways:
-
A brief scan is a quick but crucial step in assessing circulation.
-
Inspection, palpation, and vital signs help detect early signs of cardiovascular compromise.
-
Early identification of abnormal findings allows for prompt intervention and improved patient outcome
