The Wound Nobody Could See

Tree Lipton served in the US Air Force as fuels and security forces. He did his job. He kept others safe. He came home — but he didn’t come home whole.

The trauma happened in a place where he was supposed to be safe. He never reported it. He buried it. He moved from active duty to the reserves, hoping the change in pace would help. It didn’t.

Sleep fell apart. Mood fell apart. Drinking got worse. Two or three years later, Tree was in a VA psychiatric facility after a suicide attempt.

His motivation to keep living was simple: his wife and his daughter. That was it.

“Perpetual negative energy. Like a black hole. That’s what it feels like.”

— Tree Lipton, describing life with untreated PTSD

Five Days in Colorado with No Expectations

Tree’s wife had a relative who’d been working with veterans. Mark Squibb reached out and offered an olive branch: “If you can make it out to my place, we’ll give something a shot.”

At that point, Tree was on a stack of medications that had turned him into what he calls “a zombie.” Stage 3 hypertension. Energy swings from nothing to uncontrollable. He drove to Colorado with zero expectations.

Over five days, he did multiple sessions per day on a stationary bike — at least 15 minutes each — with oxygen switching between high and low concentrations.

After the first few sessions, something he hadn’t expected started happening.

“I had a release. It felt like a cramp — like letting go of my head. Pins and needles in places I didn’t feel before. Some part of me has been reignited.”

What Day 5 Looked Like

The emotional “ping-pong” — the erratic highs and lows that had defined his days — slowed down. His emotional responses became more stable. He cried, but it wasn’t from sadness. It was understanding. The pieces fell back together.

“I felt more complete. Like a whole piece of something split apart, and the halves fell back together.”

Before Treatment

  • Stage 3 hypertension
  • Could not maintain anger or aggression levels
  • Emotionally erratic — wide swings within hours
  • VA hospitalization, long-term inpatient stays
  • Suicide attempt
  • Zombie state from medications

After Five Days

  • Emotional swings stabilized
  • Able to process memories without re-traumatization
  • Speech and thought patterns clearer
  • Returned home able to put daughter to bed
  • “I’m still here. I did all the things. I’m still here.”
  • Went on to complete full year of trade school

His Family Got Their Dad Back

The week after Tree returned home, he told his wife: “I’ll put Theresa to bed.”

She didn’t know what to do with herself. For years, bedtime had been impossible — too much noise in Tree’s head, not enough patience. His wife had been the sole parent by necessity.

In Their Own Words

“I got my husband back. It was like a miracle. I was able to get my life back, too — because I’d put myself on the back burner for both him and our daughter.”

— Tree’s wife

“She comes and asks me for stuff. She asks my opinion. She asks what I think. She asks for help. She asks for advice. I’m the dad — I’m somebody she can come to, as opposed to somebody who needed to be avoided.”

— Tree Lipton

Why This Works Without Talking About the Trauma

Years of talk therapy hadn’t unlocked what five days of oxygen training did. Tree noticed the difference.

“Kind of magical to just breathe deep and seek peace and have that be the primary vehicle for healing. Kind of hilarious how easy it was and how quickly it changed things inside my head.”

The Biology Underneath the Trauma

Talk therapy addresses the psychological layer. Oxygen training addresses the biological layer underneath it.

Trauma — especially repeated trauma — creates inflammation and restricts blood flow to the brain’s regulatory centers. Those systems go offline. They’re not destroyed. They’re just starved of what they need to function.

When oxygenated blood reaches those dormant areas, they come back online. Often quickly. Often in ways that years of medication and therapy hadn’t been able to produce.

“You don’t need to talk about whatever it is you’re going through,” Tree says. “If you can get on a bike and spin, you can do this.”

Frequently Asked Questions

Tree’s PTSD originated from a traumatic experience during his deployment in the Air Force — not from combat, but from a personal assault in a place where he expected to be safe. He chose not to report it at the time. He describes the result as “perpetual negative energy, like a black hole” — persistent emotional dysregulation, sleep disruption, drinking, manic episodes, and eventually suicide attempts.
He left it as a “closed case” — he didn’t want to pursue the pain of a report, didn’t feel his account would be believed, and didn’t want to relive the experience in a formal process. When he reached out to his NCO in the first week back, he was laughed off. So he dropped it, and the condition worsened over the following two to three years before he finally entered the VA system.
Tree describes the first sessions as producing a physical release — “like a cramp letting go of my head.” He felt pins and needles in parts of his brain he hadn’t felt before, and described the emotional experience as pieces falling back together. The hypoxic intervals (low oxygen phases) were intense but manageable, and the recovery when oxygen was restored was immediate and pronounced.
She said she “got her husband back” and described it as “like a miracle.” She noted that she’d been a full-time caregiver for years — emotionally responsible for managing Tree’s environment and her daughter largely alone. After his treatment, she had to adjust to no longer needing to do that. The first sign: Tree offered to put their daughter to bed for the first time — something that had previously been impossible due to his emotional state.
LiveO2 works at the biological layer. PTSD — especially when combined with concussion history or blast exposure — can have an organic brain component: reduced blood flow to the brain’s regulatory centers. Those areas go offline, not from psychological damage, but from physical hypoxia. Oxygen training restores blood flow and allows those neural systems to function again. The trauma doesn’t disappear, but the brain regains the capacity to process it without being overwhelmed.
“Life is measured in opportunity. We should never deny ourselves the opportunity to heal.” Tree emphasizes that PTSD is not exclusive to combat veterans or any specific experience — anyone can be injured, and anyone can have a hard time recovering. He also notes that you don’t have to understand the mechanism or talk about what happened. You just need to get on the bike. The biology does the rest.
