⚠ Prescription Required
A valid physician prescription is required to purchase the P2-E7 Portable Oxygen Concentrator. Broadway Home Medical cannot dispense this device without a current, valid Rx from a licensed prescriber.

The Rhythm Healthcare P2-E7 is a portable pulse-dose oxygen concentrator weighing 4.37 lbs. with seven flow settings (1–7), up to 7 hours of battery life on Setting 1, a maximum oxygen output of 1,400 ml/min, and a 2.8" LCD display. It is designed for 24/7 use, FAA compliant for commercial air travel, and includes both an AC and DC car charger. The auto-sensing 100–240V AC power supply works worldwide. HCPCS codes E1390 and E1392. Device warranty is 5 years (units purchased on or after January 1, 2026). A prescription from a licensed physician is required to purchase this device.

A portable oxygen concentrator pulls ambient air, filters it, and concentrates the oxygen to therapeutic levels — eliminating the need to carry heavy compressed oxygen tanks. The P2-E7 delivers pulse-dose oxygen in flows synchronized to the user's breathing pattern. At 4.37 lbs. with a seven-hour battery at the lowest setting, it's one of the most practical POCs available for users who need supplemental oxygen across a full day of activity, travel, or outings. Purchasing the P2-E7 requires a valid prescription — this is a federal requirement for oxygen therapy equipment dispensed in the United States.
The P2-E7 is a pulse-dose concentrator, meaning it delivers oxygen in timed bursts (pulses) synchronized to the user's inhalation rather than flowing continuously. When you breathe in, the unit delivers a pulse of concentrated oxygen. When you breathe out, no oxygen is delivered. This is more efficient than continuous flow because oxygen isn't wasted between breaths — which is why pulse-dose units can be significantly smaller, lighter, and longer-running on battery than continuous-flow units of the same output class. Pulse dose is appropriate for many oxygen therapy patients, but not all — some patients require continuous flow. Your prescribing physician specifies the delivery mode and flow setting on your prescription. If your prescription calls for continuous flow oxygen, the P2-E7 is not the appropriate device. Broadway Home Medical can help confirm whether the P2-E7 matches your prescription. About pulse dose vs. continuous flow →
The P2-E7 has seven flow settings, giving prescribers and users precise control over oxygen delivery. Higher settings deliver more oxygen per pulse but reduce battery life proportionally. The chart below shows rated battery duration at each setting. Actual duration varies with breathing rate, activity level, temperature, and battery condition.
| Setting | Battery Duration | Approximate Use Case |
|---|---|---|
| 1 | 7 hours | Low activity / rest |
| 2 | 5.5 hours | |
| 3 | 3.7 hours | |
| 4 | 3 hours | |
| 5 | 2.5 hours | |
| 6 | 2 hours | |
| 7 | 1.7 hours | Higher activity demand |
The P2-E7 conforms to all applicable FAA criteria for portable oxygen concentrator carriage and use on board commercial aircraft. FAA regulations require that POCs used on commercial flights appear on the FAA-accepted device list — the P2-E7 qualifies. Rhythm Healthcare provides an FAA Travel Letter for the P2-E7 to assist with airline documentation. Individual airlines may have additional requirements for advance notification, documentation, and battery quantity limits. Always confirm your specific carrier's policy well before your travel date. The included DC car charger also allows charging during road travel between flights. About FAA compliance and air travel →
"The P2-E7 is one of the lightest pulse-dose portable concentrators we carry with this kind of output range and battery life. Under five pounds with seven hours at Setting 1 and seven flow settings gives a lot of flexibility for patients whose oxygen needs vary with activity. The five-year device warranty is one of the strongest in this class."

Common questions from customers at Broadway Home Medical about the P2-E7 Portable Oxygen Concentrator.
Yes — a valid prescription from a licensed physician is required to purchase the P2-E7 Portable Oxygen Concentrator. This is a federal requirement. Oxygen therapy equipment is classified as durable medical equipment requiring a physician order, and Broadway Home Medical cannot dispense the P2-E7 without a current, valid Rx. Your prescription should specify the flow setting, delivery mode (pulse dose), and hours of use per day. If you have a prescription, bring it, email it, or fax it to either of our Wichita locations.
Pulse dose oxygen is delivered in timed bursts synchronized to your inhalation — when you breathe in, the unit delivers a pulse of concentrated oxygen; when you breathe out, it pauses. This is more efficient than continuous flow, which is why pulse dose units can be significantly lighter and longer-running on battery. However, pulse dose is not appropriate for all patients — some require continuous flow oxygen, particularly during sleep or at certain activity levels. Your prescribing physician will specify whether pulse dose or continuous flow is appropriate for your clinical situation. If your prescription calls for continuous flow, the P2-E7 is not the correct device.
Your flow setting is specified by your prescribing physician on your oxygen prescription — do not adjust the setting above what is prescribed without consulting your doctor. Higher settings deliver more oxygen per pulse but reduce battery life. The P2-E7 offers seven settings, giving your physician flexibility to prescribe the exact output level your condition requires. If you feel your prescribed setting is not meeting your needs, contact your physician rather than self-adjusting to a higher setting.
Yes — the P2-E7 is FAA compliant for carriage and use on board commercial aircraft. Rhythm Healthcare provides an FAA Travel Letter for the P2-E7 to assist with airline documentation requirements. Airlines typically require advance notification (usually 48–72 hours before flight), documentation of the device, and may have specific battery quantity rules. Always confirm your carrier's specific policy before travel. The included DC car charger allows recharging between flights during ground transport.
Yes — the P2-E7 is designed for 24/7 continuous use. When plugged into AC power it operates indefinitely; on battery it runs up to 7 hours at Setting 1 and recharges in approximately 4 hours via AC. The included DC car charger allows use and charging during vehicle travel. Users who require oxygen continuously should plan their charging schedule to ensure the battery is charged before departing on outings, and bring the AC charger for access to power at their destination.
The P2-E7 includes six alarm types: power failure (loss of power), temperature (unit is too hot), low oxygen (oxygen output below therapeutic threshold), battery (battery critically low), pressure (internal pressure issue), and sieve bed replacement (sieve bed has reached end of service life). The oxygen sensors alert specifically when concentration drops below 87% or below 50%. If any alarm activates, stop using the device, consult your emergency oxygen backup plan, and contact Broadway Home Medical or your respiratory care provider for service guidance.
Prescription Required: The P2-E7 Portable Oxygen Concentrator is a regulated medical device requiring a valid physician prescription under federal law. Broadway Home Medical cannot dispense this device without a current Rx. The oxygen flow setting, delivery mode, and hours of daily use specified on your prescription must match the device's capabilities. Do not self-adjust your prescribed flow setting without consulting your physician.
The P2-E7 is a pulse-dose portable oxygen concentrator intended for use by patients with a physician prescription for supplemental oxygen. It is not appropriate for all oxygen therapy patients — continuous flow requirements cannot be met by a pulse-dose device. Battery duration varies with breathing rate, activity level, altitude, temperature, and battery condition. HCPCS codes E1390 and E1392 should not be considered legal advice and do not guarantee reimbursement. Medicare coverage requires documented medical necessity, qualifying diagnosis, and blood oxygen saturation criteria. FAA compliance applies to commercial aircraft; other transportation modes may have separate requirements. Warranty terms apply to units purchased on or after January 1, 2026 — prior purchases remain subject to original warranty terms.
