What systolic blood pressure value below which hypotension is listed as a contraindication for CPAP?

The main idea is that CPAP can improve oxygenation and reduce the work of breathing, but it also increases intrathoracic pressure. In someone who is hypotensive, this added pressure can further decrease venous return to the heart and lower cardiac output, worsening perfusion. That’s why a systolic blood pressure under about 90 mmHg is a contraindication to starting CPAP. If the patient’s BP is at or above 90 and they can protect their airway and cooperate, CPAP may be used to help with respiratory distress. In hypotension, prioritize stabilizing circulation and airway management rather than initiating CPAP.
