|Lavon O ||Case study||Hoist rescue missions with mechanical ventilation of the patient using the Oxylator EM-100®||intubated prehospital trauma patients (ISS > 15), n = 5||Automated flow-limited mechanical ventilation is efficient for ventilating adult patients with protected airway during the short periods of hoist rescue and facilitates a smooth rescue operation.|
|Burns BJ ||Case study||One intubated prehospital trauma patient underwent resuscitation bag ventilation during a stretcher hoist. Manikin model of bag ventilation during a stretcher hoist in downwash of an AW 139 helicopter, with two resuscitation bags with differing compliances.||intubated prehospital trauma patient, n = 1 manikin model, n = 2||
50 ft under the rotor disc, the resuscitation bag failed due to compression by the downwash.|
The stiffer, less compliant resuscitation bag did not fail in the manikin model.
|Murphy D ||Randomized crossover trial||Adults suspended in single sling, double sling, supine in a rescue stretcher, and in a rescue basket. Primary variables measured were FEV 1, FVC, FEV 1/FVC ratio, and IC in each modality versus control. Secondary measurements: peripheral oxygen saturation, heart rate, and respiratory rate.||healthy adults, spontaneous breathing, n = 27||
The rescue basket was not associated with any change in measured outcomes.|
The stretcher was associated with small decreases in expiratory volumes, but an increase in IC.
Single sling had detrimental effects on respiratory function (not applicable after advanced airway management).
