Answer :
Final answer:
The best indicator of effective ventilations for an asthma patient is when the patient's chest rises and falls. This shows that air is entering the lungs properly. Other signs may indicate complications or ineffective ventilation.
Explanation:
Indicator of Effective Ventilations in Asthma Patients
When managing an asthma patient who requires ventilation, it is crucial to assess the effectiveness of your interventions. Out of the options provided, the best indicator of effective ventilations is the patient's chest rises and falls with ventilations. This response signifies that air is entering the lungs adequately and that the ventilatory effort is successfully achieving positive pressure ventilation.
Here's a brief evaluation of the given options:
- The patient becomes quiet and stops breathing on his own: While a quiet patient may indicate improvement, it can also be misleading. It could indicate a lack of respiratory drive and potential deterioration.
- The patient's stomach begins expanding with ventilations: This indicates poor ventilation technique, leading to air entering the stomach rather than the lungs, which can cause gastric distension and respiratory compromise.
- The patient's color changes from cyanotic to mottled: Cyanosis indicates a lack of oxygen, and a change to mottled may suggest worsening circulation or perfusion, which is not a good sign.
- The patient's chest rises and falls with ventilations: This is the most reliable indicator that your ventilations are effective, demonstrating that air is reaching the lungs.
In summary, observing chest rise and fall is a positive sign that ventilation is being effectively delivered to the lungs, crucial for the patient's recovery.
