Checking Responsiveness in Elderly Parents: Why a Sternal Rub Is Not a Home Test

When Your Parent Won't Wake Up

Finding your elderly parent unresponsive — or less responsive than usual — is terrifying. If they do not respond to your voice and a gentle shoulder tap, call 911 immediately, then check whether they are breathing normally.

The sternal rub is a painful stimulus used by trained clinicians. It is not necessary for a caregiver to decide whether an unresponsive person needs emergency help, and it should not delay the emergency call.

Start With the Basics Before Any Physical Check

Use a shout-tap-shout check for no more than 10 seconds:

1. Call their name loudly from across the room, then from beside them
2. Tap their shoulders firmly while speaking their name
3. Shout again and look for normal breathing

If they respond to voice or touch but are difficult to wake or are not acting normally, call 911 or seek immediate medical help.

Why a Sternal Rub Is Not a Home Test

Because a sternal rub can cause bruising or skin injury, particularly in older adults or people taking blood thinners, do not use it as a home responsiveness test. If your parent does not respond to voice or a gentle shoulder tap, call 911 immediately. If they are not breathing normally or are only gasping, begin CPR with chest compressions and follow the dispatcher's instructions. If they are breathing normally, keep monitoring them and follow the dispatcher's instructions.

What to Tell the 911 Dispatcher

When you call, the dispatcher will ask about your parent's responsiveness. Relay exactly what you found:

• "They are not responding to voice or touch" — describe whether they are breathing normally, not breathing, or only gasping
• "They respond to voice or touch but won't fully wake" — this tells dispatch they have an acute change in responsiveness
• "They're breathing normally" or "They're not breathing normally" — use the dispatcher's questions to describe what you see

Also report any medications they take that cause sedation (opioids, benzodiazepines, sleep medications, muscle relaxants), the time you last saw them alert, and whether you find any medication bottles nearby that suggest a dosing error.

Common Causes of Reduced Responsiveness in Seniors

Unresponsiveness in an elderly parent isn't always a stroke or cardiac arrest. Common causes include:

• Medication effects — oversedation from pain medications, sleep aids, or accidental double-dosing
• Hypoglycemia — dangerously low blood sugar, especially in diabetics on insulin
• Severe infection — sepsis can present as profound lethargy before other symptoms appear
• Stroke — particularly a large territory stroke or brainstem event
• Post-seizure state — a seizure can leave the person deeply unresponsive for minutes to hours afterward
• Severe dehydration — electrolyte imbalance affecting brain function

Regardless of the cause, an elderly parent who does not respond to voice or touch, or who is not breathing normally, needs emergency help. Don't try to diagnose the cause — get EMS there.
