The astronaut has no heartbeat and no respiration, but does have blood pressure. While this is shown as a scientific implausibility, it's not explained how the doctors can detect the astronaut's blood pressure without a heartbeat. Blood pressure readings using a sphigmomanometer (blood pressure cuff) rely on the heartbeat to determine both the systolic (which is the pressure of a compressing heart) and diastolic (which is the pressure of a relaxed heart). In other words, no matter what technobabble you want to offer, there's no way to determine blood pressure without a heartbeat.
