Handheld Pulse Oximeter

WhatsApp Order
A Handheld Pulse Oximeter is a professional-grade, portable medical device used by healthcare providers for accurate and reliable monitoring of blood oxygen saturation (SpO2) and pulse rate. It consists of a durable, feature-rich monitor unit and separate, interchangeable sensors for use on fingers, toes, or ears. Superior to basic fingertip models, it offers advanced functions like configurable alarms, detailed plethysmograph display, trend memory, and data connectivity. Its robust design, clinical accuracy under challenging conditions (motion, low perfusion), and versatility make it an essential tool in hospitals, clinics, ambulances, and home health for patient assessment and monitoring.
Description

Handheld Pulse Oximeter

PRIMARY CLINICAL & DIAGNOSTIC USES

1. Professional Clinical Spot-Check & Continuous Monitoring:
  • Primary Use: Designed for use by healthcare professionals across all care settings for both quick spot checks and short-term continuous monitoring of oxygen saturation (SpO2) and pulse rate. It is the standard tool in physician offices, clinics, and nursing stations.
  • How it helps: Provides healthcare professionals with a reliable, professional-grade instrument that delivers accurate readings they can trust for clinical decision-making, whether for a quick check during rounds or continuous monitoring of a patient with respiratory concerns.
2. Hospital Ward & Emergency Department Assessment:
  • Primary Use: Used for initial patient triage, routine vital sign rounds, and monitoring patients who require more frequent checks than those on bedside monitors but not continuous telemetry.
  • How it helps: Allows busy emergency and ward nurses to quickly assess oxygenation in every patient, identifying those who need immediate attention while providing routine monitoring for stable patients.
3. Respiratory Therapy & Pulmonary Function:
  • Primary Use: A core tool for respiratory therapists to assess patients with acute and chronic lung diseases (COPD, pneumonia, asthma exacerbations) before and after treatments like bronchodilator administration or oxygen therapy.
  • How it helps: Gives respiratory therapists immediate feedback on whether treatments are working, showing them in real-time how a patient’s oxygen levels respond to breathing treatments and adjustments in oxygen therapy.
4. Anesthesia & Sedation Monitoring:
  • Primary Use: Employed during procedural sedation, in post-anesthesia recovery (PACU), and by anesthetists for stable patients undergoing minor procedures as a reliable, portable monitor.
  • How it helps: Provides an extra layer of safety during procedures that require sedation, alerting the medical team immediately if a patient’s oxygen levels drop so they can intervene before any harm occurs.
5. Neonatal & Pediatric Care:
  • Primary Use: Often preferred over fingertip models for infants and small children due to the availability of durable, reusable sensors (e.g., wrap-style or adhesive) that are less likely to be dislodged and can be used on fingers, toes, or ears.
  • How it helps: Ensures that even the smallest patients receive accurate, continuous oxygen monitoring with sensors designed to stay in place on tiny fingers and toes, protecting vulnerable infants and children.

SECONDARY & SUPPORTIVE USES

1. Sleep Studies & Overnight Monitoring: Used in sleep labs or at home for overnight oximetry studies to screen for sleep-disordered breathing like obstructive sleep apnea, providing continuous trend data over many hours that can reveal dangerous drops in oxygen during sleep.
2. Patient Transport & Ambulance Services: Its robust build and reliable battery life make it ideal for monitoring patients during intra-hospital transfers (e.g., to Radiology) or in ambulances during emergency transport, ensuring continuous monitoring even when patients are moving.
3. Home Healthcare Visits: Used by visiting nurses and home health aides to obtain accurate readings for patients with advanced COPD, heart failure, or those recovering from serious illness at home, extending hospital-quality monitoring into the home.
4. Long-term Care Facility Rounds: A durable, professional-grade device for daily vital sign checks on elderly residents in nursing homes, helping detect early signs of respiratory decline in a vulnerable population.
5. Sports Medicine & High-Altitude Research: Used in controlled settings where a more robust device than a consumer fingertip model is required for accurate data collection during exercise physiology tests or altitude simulation, supporting athletic performance and scientific research.
KEY PRODUCT FEATURES

1. BASIC IDENTIFICATION ATTRIBUTES

  • Device Type: Handheld, Professional Medical Pulse Oximeter.
  • Form Factor: Consists of a separate, ruggedized main monitor unit and a detachable sensor probe connected via a flexible cable.

SAFETY HANDLING PRECAUTIONS

1. SAFETY PRECAUTIONS

  • Personal Protective Equipment (PPE): Follow standard infection control. Clean and disinfect the sensor and monitor (as per protocol) between patients. Wear gloves if risk of exposure to bodily fluids.
  • Sensor Placement & Selection:
    • Choose the correct sensor type and size for the patient (adult, pediatric, neonatal, finger, toe, ear).
    • Ensure the sensor site is clean, dry, and has adequate perfusion. Rotate sites during long-term monitoring to prevent pressure sores.
    • Ensure the sensor is properly aligned (LEDs opposite the photodetector).
  • Device Interpretation: Understand that the plethysmograph is as important as the numbers. A poor or erratic waveform indicates an unreliable SpO2 reading, regardless of the displayed number. Correlate readings with the patient's clinical condition.

2. FIRST AID MEASURES

  • General: The device is a monitor. In case of a hypoxemic emergency (low SpO2 with distress), follow clinical protocols for airway management and oxygenation.
  • Device Malfunction: If the device fails, provides consistently implausible readings, or shows error messages, replace it with a known-working monitor immediately.
  • Battery Issues: If the rechargeable battery pack is damaged, swollen, or leaking, discontinue use and follow facility procedures for safe disposal.

3. FIRE FIGHTING MEASURES

  • Flammability: Plastic housing, display, and internal electronics are combustible. The lithium-ion battery poses a fire risk if damaged or improperly charged.
  • Extinguishing Media: For electrical/battery fires, use a COâ‚‚ or dry chemical (Class C) extinguisher. A Lithium-ion battery fire may require a Class D extinguisher or large quantities of water to cool and prevent thermal runaway.
  • Hazardous Combustion Products: Toxic fumes from burning plastics and battery chemicals.
  • Firefighter Instructions: Wear full PPE and SCBA. If safe, remove the device from the vicinity of the patient. Be aware of the potential for battery explosion.
