    摘要： This disclosure describes systems and methods for adjusting a determination of the amount of breathing assistance a patient requires while on a ventilator. In general, in determining the amount of breathing assistance required, the ventilator takes into account an airflow resistance attributable to the tube used to deliver ventilation to the patient's lungs. A tube compensation factor is calculated using a tube compensation algorithm, or similar equation. In particular, the tube compensation factor represents the resistance to airflow attributable to the breathing tube itself based on, inter alia, frictional drag, turbulence, and an internal diameter of the tube. Changes in the tube during ventilation impact the calculation of the breathing assistance required by the patient and are accounted for when compensating for the breathing tube.

    摘要： The current techniques provide a system for monitoring a physiological parameter of a patient using microneedles that are coupled to an optical system, allowing spectroscopic measurements to be made immediately below the outer layer of the epidermis. In embodiments of the present invention, the results of the spectroscopic measurements are used to control the administration of a drug through an intravenous tube. In other embodiments, the microneedles may be coated with a drug for administration to the patient. In other embodiments, the microneedles may be mounted in a probe, wherein an actuator is used to move the needles into contact with the skin, and a drug delivery system is used to infuse the drug into the patient. A method for making needles is also provided.
