Treatment - Devices

Intervention 1: Vibration of the back of thorax using vibrator device once for two minutes.

Intervention 2: Percussion of the back of thorax knocking gentling one for four minutes.

Intervention 3: Manual hyperinflation using ambo bag to inspire via tracheal tube or thoracotomy, stop for three seconds then expire rapidly relaxing ambo bag.

Design outcomes

Primary

Measure	Time frame
The outcome of interest is cardiopulmonary function which will be assessed as follows: (a) systolic and diastolic blood pressure per mmHg using monitor device; (b) heart beat per minute using monitor device; (c) arterial oxygen saturation per percent using monitor device; (d) assessing pulmonary compliance per mL/mBar using monitor device; (e) airway resistance per mBar/mL/s using monitor device. Timepoint: 5 min. Method of measurement: Monitor device.	—
