Our Summary

This study is about how we can measure cough strength after lung surgery and if a certain technique can improve it. After lung surgery, patients often have a weak cough, which can lead to lung complications. The researchers wanted to see if they could use a measure called the peak expiratory flow rate (PEF) to gauge cough strength. They also wanted to test if compressing the chest during the breath out phase could make the cough stronger.

They studied 153 patients who had had lung surgery. Of these, 102 had a strong enough cough and 51 had a weak cough. They found that PEF could indeed be used to measure cough strength. They also found that when they compressed the chest wall during the breath out phase, both the PEF and another measure of lung function (FEV1) were higher than when they didn’t compress the chest.

So, they concluded that PEF can be used to quantify cough strength and that chest wall compression can improve the cough in patients with a previously weak cough.

  3. What is the peak expiratory flow rate (PEF) and how does it relate to cough strength?

Doctor’s Tip

A helpful tip a doctor might tell a patient about lung surgery is to practice deep breathing exercises regularly to help strengthen the lungs and improve cough strength. Additionally, following post-operative instructions such as taking prescribed medications, staying hydrated, and avoiding smoking can also aid in the recovery process. It’s important to follow up with your healthcare provider for regular check-ups and to address any concerns or complications that may arise.

Suitable For

Patients who are typically recommended lung surgery include those with lung cancer, chronic obstructive pulmonary disease (COPD), emphysema, lung infections, lung nodules, and other lung conditions that have not responded to conservative treatment. Additionally, patients with severe breathing difficulties, persistent cough, chest pain, and other symptoms that significantly impact their quality of life may also be candidates for lung surgery.

Timeline

Before lung surgery:

  • Patient undergoes pre-operative evaluations and testing to determine eligibility for surgery
  • Patient meets with surgeon to discuss procedure and potential risks
  • Patient may need to stop certain medications or make lifestyle changes before surgery
  • Patient undergoes surgery, which can vary depending on the type of procedure being performed

After lung surgery:

  • Patient is closely monitored in the recovery room for any complications or side effects
  • Patient may need to stay in the hospital for a period of time for observation and pain management
  • Patient undergoes physical therapy to regain strength and lung function
  • Patient may experience coughing and breathing difficulties, which can lead to lung complications
  • Patient is discharged from the hospital and continues with follow-up appointments and rehabilitation
  • Researchers study cough strength using measures like PEF and chest wall compression to determine ways to improve lung function post-surgery.
