Which physiological response might indicate that a tilt table session needs to be halted?

1. Increased heart rate

2. Signs of discomfort

3. Signs of intolerance such as dizziness

4. Increased blood pressure

The correct answer is: Signs of intolerance such as dizziness

The indication to halt a tilt table session due to signs of intolerance is crucial for ensuring patient safety and comfort. Signs of intolerance, such as dizziness, suggest that the patient may be experiencing a negative physiological response to the upright position. This can result from inadequate cardiovascular adjustments, which could lead to more severe complications like syncope or blackouts. Recognizing signs like dizziness can be vital in guiding care, as they indicate that the body is struggling to maintain stable blood flow and pressure in the upright position. This awareness allows a therapist to intervene promptly, ensuring that the patient's needs are prioritized, and avoiding unnecessary distress or injury. Increased heart rate and increased blood pressure can sometimes be expected responses during tilt table training as the body works to accommodate to the change in position. Similarly, while signs of discomfort should certainly be monitored, they are not as definitive of physiological intolerance as dizziness. Therefore, identifying signs of intolerance, such as dizziness, provides a clear and urgent reason to stop the session and reassess the patient's condition.
